Green Seal 2022 — GS-8 Edition 5.7 Standard for Cleaning Products for Household Use
The binding text of Green Seal’s voluntary environmental certification standard for general-purpose, bathroom, glass, and carpet cleaning products marketed specifically for household or similar residential use. Edition 5.7 was issued June 23, 2022, replacing Edition 5.6 from November 11, 2021; per the Foreword (p. 4) corrections and clarifications were last made to this standard on January 28, 2022. The version retrieved (©2021 Green Seal, Inc., file Green_Seal_GS-8_Household_Cleaners_2022.pdf) is 22 pages organised into 6 main clauses (Scope; Product-Specific Performance Requirements; Product-Specific Health and Environmental Requirements; Packaging Requirements; Product Label Requirements; Trademark Use Requirements) and 4 normative annexes (Definitions; Powders/Solids/Non-Aqueous Liquids; Enzymes; Microorganisms) plus one informative appendix (Appendix 1 Scope).
Heavy-metal coverage in Edition 5.7 operates through two distinct by-name mechanisms across the Product-Specific Health and Environmental Requirements and Packaging Requirements clauses. First, the Other Prohibited Ingredients criterion (section 3.10) prohibits in the undiluted product the heavy metals lead, hexavalent chromium, or selenium, either in the elemental form or compounds, alongside 2-butoxyethanol, alkylphenol ethoxylates, phthalates, ozone-depleting compounds, and optical brighteners. Second, the Packaging Requirements > Heavy Metal Restrictions sub-clause (section 4.5) sets a sum-of-concentrations numerical ceiling on lead, mercury, cadmium, and hexavalent chromium in primary packaging: these four metals shall not be intentionally introduced, and the sum of their concentration levels shall not exceed 100 parts per million by weight (0.01%), with an exception for refillable packages or packages that would not exceed this maximum but for the addition of recovered material. A parallel Other Restrictions sub-clause (section 4.6) prohibits intentional introduction of phthalates, bisphenol A, and chlorinated packaging material to a plastic primary package, with the same post-consumer-material exception. A separate Per- and Polyfluorinated Alkyl Substances (PFAS) criterion (section 3.9) prohibits any PFAS in the undiluted product, mirroring the parallel § 3.9 PFAS clause in the sibling greenseal2024-gs37-industrial-institutional-cleaners but absent from the sibling greenseal2022-gs52-specialty-household-cleaners.
GS-8 covers household general-purpose, bathroom, glass, and carpet cleaning products that fall outside the specialty household scope of the sibling Green Seal Standard GS-52 (Specialty Cleaning Products for Household Use; greenseal2022-gs52-specialty-household-cleaners) and outside the industrial and institutional scope of the sibling greenseal2024-gs37-industrial-institutional-cleaners. Appendix 1 (p. 22) enumerates household products INCLUDED in GS-8 (bathroom cleaners; floor cleaning products; glass cleaners and mirror cleaning products; general-purpose cleaners; carpet cleaners; products that contain microorganisms; products that contain enzymes and are sold and/or designed for use in non-spray packaging) and EXCLUDED from GS-8 (air fresheners; cleaners/degreasers marketed for production/maintenance applications, covered by GS-34; deck and outdoor furniture products for household use, covered by GS-52, and for industrial and institutional use, covered by GS-53; antimicrobial pesticide products such as disinfectants or sanitizers for household use, covered by GS-52, and for industrial and institutional use, covered by GS-53; floor finish and finish strippers, covered by GS-40; furniture polish products, covered by GS-52 and GS-53; general-purpose, restroom, glass, and carpet cleaners for industrial and institutional use, covered by GS-37; hand cleaning products for industrial and institutional use, covered by GS-41, and for household use, covered by GS-44; motor vehicle cleaning products for household use, covered by GS-52, and for industrial and institutional use, covered by GS-53; oven cleaning products for household use, covered by GS-52, and for industrial and institutional use, covered by GS-53; paint remover/thinner products; specialty cleaning products for household use, covered by GS-52, and for industrial and institutional use, covered by GS-53; upholstery cleaning products for household use, covered by GS-52, and for industrial and institutional use, covered by GS-53; products that contain enzymes and are sold in, or designed for use in, spray packaging).
This page documents the binding standard text as the operative GS-8 reference for general-purpose, bathroom, glass, and carpet cleaning products marketed for household use. The sibling greenseal2022-gs52-specialty-household-cleaners is the operative reference for the specialty household-cleaning product scope; the sibling greenseal2024-gs37-industrial-institutional-cleaners is the operative reference for the industrial and institutional general-purpose, restroom, glass, and carpet cleaning scope; the sibling greenseal2009-gs37-version-comparison is the 2006-vs-2008 GS-37 version-comparison artefact.
Key numbers
Numerical content below is the subset most relevant to HMI synthesis on general-purpose household cleaning product groups: the two heavy-metal-specific clauses in full, plus the adjacent numerical thresholds (VOC limits, oral/inhalation LC/LD50, vapor-pressure thresholds, biodegradability percentages, BCF-equivalent biodegradability gate, aquatic LC50, eutrophication phosphorus, combustibility flashpoint, post-consumer-material percentage, dilution-instruction temperature, and the Annex B/C/D thresholds) that contextualise the heavy-metal limits within the standard’s overall quantitative register.

CARB regulatory VOC limits (Edition 5.7 reproduced subset, p. 9-10 table)
The standard reproduces the current California Air Resources Board (CARB) regulatory limits for VOC content as the binding ceiling for product categories regulated by CARB. The full table at pp. 9-10 spans six product-category rows. Per footnote 4 (p. 9), these limits are a reference to the current CARB regulatory limits and will be updated to reflect any future CARB amendments. Where the row corresponds to a product type not strictly enumerated in Appendix 1’s GS-8 included scope (e.g., Spot Removers, which are GS-52 / GS-53 scope), the row is preserved for completeness because the standard’s text reproduces it without scope filtering.

Heavy-metal-specific summary
The standard captures heavy metals through two distinct regulatory mechanisms.
(1) Other Prohibited Ingredients in the formulated product (§ 3.10). The undiluted product shall not contain three named heavy metals — lead, hexavalent chromium, or selenium — in either elemental form or compounds. The same three-metal list appears in the parallel GS-52 § 3.18 Prohibited Components clause and in the parallel GS-37 § 2.1.13 Prohibited Ingredients clause. The Edition 5.7 GS-8 § 3.10 list is shorter than the parallel GS-52 § 3.18 list: GS-8 § 3.10 covers Pb/Cr-VI/Se + 2-butoxyethanol + alkylphenol ethoxylates + phthalates + ozone-depleting compounds + optical brighteners (6 categories total), whereas GS-52 § 3.18 covers Pb/Cr-VI/Se + 2-butoxyethanol + alkylphenol ethoxylates + halogenated organic solvents + nitro-musks + o-phenylphenol + ozone-depleting compounds + phthalates + polycyclic musks + TRI PBT chemicals + triclosan (11 categories total). The differences (halogenated organic solvents, nitro-musks, o-phenylphenol, polycyclic musks, TRI PBT chemicals, triclosan; plus optical brighteners which GS-8 § 3.10 lists but GS-52 lists separately as § 3.22) reflect each standard’s product-scope-specific contaminant concerns rather than a Green Seal-wide policy difference. The clause is a binary prohibition on intentional formulation with no numerical concentration threshold reproduced in the standard text.
(2) Packaging Heavy Metal Restrictions in primary packaging (§ 4.5). Lead, mercury, cadmium, and hexavalent chromium shall not be intentionally introduced to primary packaging. The sum of these four metals’ concentrations in the packaging shall not exceed 100 ppm (0.01%). An exception applies for refillable packages or packages that would not exceed but for the addition of recovered material. The Annex A definition of “Intentional Introduction” (p. 14) carves out processing aids and intermediates that impart certain chemical/physical changes during manufacturing, provided their residual presence in the primary package is below 100 ppm. The 100 ppm sum ceiling is the standard’s single explicit heavy-metal numerical limit and is identical to the parallel clauses in greenseal2022-gs52-specialty-household-cleaners § 5.5 and greenseal2024-gs37-industrial-institutional-cleaners § 3.3.1. The 100 ppm sum corresponds to the four-metals sum convention used in the U.S. Coalition of Northeastern Governors (CONEG) Model Toxics in Packaging Legislation (1989), adopted by 19+ US states, and in EU Directive 94/62/EC Article 11; Edition 5.7 does not reference those external regulations by name in the Heavy Metal Restrictions sub-clause, but the structural and numerical parallel is direct.
Heavy-metal coverage outside these two by-name clauses operates through other criterion families on a compound-by-compound basis: Prohibition of Carcinogens, Mutagens, and Reproductive Toxins (§ 3.2) covers heavy-metal compounds with IARC Group 1/2A/2B, NTP Group 1/2, EPA IRIS A/B1/B2/C carcinogen classifications, OSHA classifications, GHS Category 1 germ-cell mutagenicity (H334-equivalent threshold per Annex A Mutagen definition referencing UN 2003 Harmonized System), or California Proposition 65 reproductive toxin classifications; Skin Sensitization (§ 3.4) covers heavy-metal compounds at ingredient-level concentrations in the undiluted product; Aquatic Toxicity (§ 3.5) covers heavy-metal compounds with acute LC50 <100 mg/L; Aquatic Biodegradability (§ 3.6) gates on the organic-ingredient subset (heavy-metal compounds typically not subject to this gate); PFAS (§ 3.9) is a class-level prohibition that does not target the metallic elements covered on this page but does represent a parallel non-metal class-level prohibition added in Edition 5.7.
GS-8 lacks a Colorants clause. Unlike the sibling GS-52 (§ 3.21 Colorants) and GS-37 (§ 2.1.4 Colorants) standards, GS-8 Edition 5.7 does NOT have a Colorants criterion that names a 9-metal exclusion list (arsenic, cadmium, cobalt, hexavalent chromium, lead, manganese, mercury, nickel, and selenium). Heavy-metal coverage in colorant components within GS-8 products operates through the broader § 3.2 Carcinogens/Mutagens/Reproductive Toxins criterion and the § 3.10 Other Prohibited Ingredients clause’s three-metal list. The absence of a parallel Colorants clause in GS-8 may reflect the smaller surface area (4 in-scope categories) and the lower colorant prevalence in general-purpose, bathroom, glass, and carpet cleaning products versus the broader specialty and industrial scopes covered by GS-52 and GS-37.
Other criterion-family additions in Edition 5.7 relevant to heavy-metal-adjacent contamination
| Item | Edition 5.7 | Source location |
|---|---|---|
| PFAS — class-level prohibition (added since predecessor editions) | “The undiluted product shall not contain any ingredients or components that are Per- and Polyfluorinated Alkyl Substances (PFAS).“ | p. 10 § 3.9 PFAS |
| Animal Testing — § 3.15 | ”To avoid new animal testing, previous test results will be accepted as evidence of meeting a criterion.” Preferred methods include those recommended by the Interagency Coordinating Committee on the Validation of Alternative Methods (ICCVAM) or the European Centre for the Validation of Alternative Methods (ECVAM); other non-animal (in-vitro) test results, modeling data, data from structural analogs, and other lines of evidence may be accepted if methods are peer-reviewed and applicable. A mixture need not be tested if existing information demonstrates that each applicable component complies. | pp. 10-11 § 3.15 Animal Testing |
| Disposable Wipes — § 3.16 | Products may contain disposable wipes/towelettes/sheets or other disposable single-use materials if made from agricultural products, wood pulp, or other cellulosic materials; exception for reusable wipes/towelettes/sheets intended for multiple uses (e.g., three or more uses). | p. 11 § 3.16 Disposable Wipes |
| Ingredient threshold | ”Any constituent that comprises at least 0.01% by weight of a product, whether it is intentionally added or present as a contaminant” | p. 14 Annex A Ingredient |
| Naturally-occurring exemption from “Ingredient" | "Naturally occurring elements and chlorinated organics that may be present as a result of chlorination of the water supply, are not considered intentional components if the concentrations are below the applicable maximum contaminant levels in the National Primary Drinking Water Standards found in 40 CFR Part 141” | p. 13 Annex A Component footnote 6 |
Methods (brief)
Not applicable in the experimental sense. This is the binding text of a third-party voluntary environmental certification standard, not an analytical study. It does not perform original sampling, analytical measurement, or contamination quantification. The standard does not specify the analytical methods Green Seal uses to verify heavy-metal absence in formulated products or in primary packaging; those audit methods are located in Green Seal’s certification audit procedures, not in the standard text itself. The standard does, however, name the test methods that conformity assessment for each non-metal criterion shall follow.
The standard references the following test-method identifiers in its non-metal criteria (preserved here as scientific-method names per CLAUDE.md Part 14 Exception 2):
- Acute toxicity: existing component-level acute-toxicity data; weighted-average mixture formula TP = (Σ wt_i / TV_i)⁻¹ where TP = toxicity of product, wt_i = weight fraction of ingredient i, TV_i = toxicity value LD50 for ingredient i (§ 3.1, p. 7); pH-based skin/eye corrosivity assumption with pH ≤2.0 or pH ≥11.5 (§ 3.3, p. 8); in vitro / in vivo standard test methods accepted in lieu of testing where sufficient information exists (§ 3.3, p. 8).

Speciation. Edition 5.7 maintains the hexavalent-chromium speciation discipline: both by-name heavy-metal clauses (Other Prohibited Ingredients § 3.10; Packaging Heavy Metal Restrictions § 4.5) name “hexavalent chromium” specifically and never name “chromium” without speciation. Mercury is not speciated (the Packaging clause names “mercury” without inorganic/organic/methyl distinction; mercury does not appear in Other Prohibited Ingredients).
Basis. The Other Prohibited Ingredients clause operates as a binary prohibition on intentional formulation with no numerical concentration threshold reproduced in the standard text. The Packaging Heavy Metal Restrictions clause expresses its numerical ceiling as a sum of the four named metals’ concentrations not exceeding 100 ppm (0.01%) by weight in the packaging material; the basis is mass-per-mass of packaging, not of the formulated product within the packaging. Annex A defines “Ingredient” as any constituent comprising at least 0.01% by weight of a product, whether intentionally added or present as a contaminant. VOC content limits are expressed as percent by weight of the product as used. Eutrophic Agents phosphorus limit is expressed as percent by weight in the product as used. Acute oral toxicity threshold is mass-per-mass body weight (mg/kg). Inhalation LC50 is mass-per-volume in air at 1 hr (mg/L); note that Edition 5.7’s inhalation LC50 units (mg/L) differ from the sibling greenseal2022-gs52-specialty-household-cleaners § 3.3 which expresses inhalation LC50 as ppmV (parts-per-million by volume in air at 1 hr) — these are different units of measurement, not directly comparable without compound-specific molar-mass conversion. Aquatic LC50 is mass-per-volume in water (mg/L). Annex B’s powder/solid/non-aqueous-liquid alternate threshold of 300 mg/kg replaces the 5,000 mg/kg threshold for the oral LD50 only and does not change the inhalation, aquatic, or packaging thresholds.
Naturally-occurring elements carve-out. Annex A’s “Component” footnote 6 (p. 13) states that naturally occurring elements (and chlorinated organics from water-supply chlorination) are not considered intentional components if their concentrations are below applicable maximum contaminant levels in the National Primary Drinking Water Standards (40 CFR Part 141). The § 3.2 Carcinogens/Mutagens/Reproductive Toxins clause repeats this carve-out for that criterion specifically (p. 7). This carve-out is relevant for heavy-metal contaminants entering the product through water inputs or naturally-occurring trace presence in raw materials, distinct from intentional addition.
Implications
- The standard documents Green Seal’s current operative regulatory floor for heavy metals in general-purpose, bathroom, glass, and carpet cleaning products marketed for household use. Heavy-metal coverage operates through two by-name mechanisms (Other Prohibited Ingredients 3-metal list, Packaging 4-metal sum ≤100 ppm) plus indirect compound-by-compound coverage via the Carcinogens / Mutagens / Reproductive Toxins, Skin Sensitization, and Aquatic Toxicity criterion families. Downstream HMI synthesis citing GS-8 as a regulatory floor for heavy metals in household general-purpose, bathroom, glass, and carpet cleaning products should differentiate the by-name mechanisms (binary prohibitions on intentional addition / introduction; the 100 ppm packaging sum is the single explicit numerical ceiling) from indirect coverage via the broader criterion families.
- GS-8 and the sibling greenseal2022-gs52-specialty-household-cleaners and greenseal2024-gs37-industrial-institutional-cleaners form a three-standard Green Seal regulatory triangle for cleaning products: GS-8 covers household general-purpose / bathroom / glass / carpet; GS-52 covers specialty household (adhesive remover, boat cleaning, dish cleaning, motor vehicle cleaning, oven cleaning, etc.); GS-37 covers industrial and institutional general-purpose / restroom / glass / carpet. All three use the same Packaging Heavy Metal Restrictions 4-metal sum and 100 ppm ceiling. All three name Pb, Cr-VI, and Se as Prohibited Ingredients / Prohibited Components in the undiluted product. GS-8 and GS-37 (but not GS-52) include a PFAS § 3.9 / § 2.1.10 prohibition. GS-52 and GS-37 (but not GS-8) include a Colorants clause naming a 9-metal exclusion list. Downstream HMI synthesis treating Green Seal as a regulatory baseline for heavy metals in cleaning products should route GS-8 to household general-purpose / bathroom / glass / carpet categories; GS-52 to household specialty categories; and GS-37 to industrial and institutional general-purpose categories; the gap between GS-8’s two-mechanism heavy-metal coverage and GS-52’s / GS-37’s three-mechanism coverage is by-name only and does not change the underlying binary prohibition on intentional addition.
- Edition 5.7’s shorter Other Prohibited Ingredients list (§ 3.10) versus GS-52’s broader Prohibited Components list (§ 3.18) reflects the narrower household-cleaner scope of GS-8 (general-purpose / bathroom / glass / carpet) versus the broader specialty household scope of GS-52. Both standards share the Pb / Cr-VI / Se three-metal baseline and the 2-butoxyethanol + alkylphenol ethoxylates + phthalates + ozone-depleting-compounds shared organic-substance baseline. The additions in GS-52 § 3.18 (halogenated organic solvents, nitro-musks, o-phenylphenol, polycyclic musks, TRI PBT chemicals, triclosan) reflect specialty-product-specific concerns (motor vehicle cleaners, boat cleaners, dish soaps with antimicrobial claims, etc.) rather than a Green Seal-wide policy difference. Future synthesis comparing the two standards should treat the broader GS-52 § 3.18 list as a scope-driven addition rather than as evidence of policy drift.
- The 50°F cold-tap-water dilution ceiling in GS-8 § 2.1 and § 5.2 is a household-use design requirement (typical residential cold-tap water reaches ≤50°F across most US climates and seasons) that drives the standard’s performance-criterion test conditions and the in-use disclosed dilution-instruction label requirement. This is GS-8-specific (GS-52 § 3.23 instead specifies 1:8 minimum dilution ratios for certain specialty categories; GS-37 § 4.4.1 specifies 1:32 / 1:16 dilution ratios by category for industrial and institutional categories). HMI synthesis on household versus institutional cleaning-product performance should note this water-temperature constraint as a household-use design parameter, not as a heavy-metal limit.
- This standard text is not a primary source for any contamination distribution, occurrence value, or threshold-setting analysis. It is the binding programme document recording what compliance to GS-8 requires. HMTc threshold-setting work on household general-purpose / bathroom / glass / carpet cleaning product categories should treat this standard as upstream regulatory context, not as a literature contributor to per-analyte percentile calculations.
Limitations
- Standard text, not occurrence data. The standard contains no original sampling, no analytical measurements, no contamination distributions, and no by-product occurrence values. It documents what compliance to GS-8 Edition 5.7 requires, not what products actually achieve. Any HMI session reasoning about how many household general-purpose / bathroom / glass / carpet cleaning products meet the GS-8 numerical limits must consult Green Seal’s certification database (greenseal.org) or independent occurrence surveys, not this standard text.
- One explicit heavy-metal numerical limit. The single explicit heavy-metal numerical limit is the § 4.5 Packaging Heavy Metal Restrictions 100 ppm sum-of-concentrations ceiling on the four named metals (Pb + Hg + Cd + Cr-VI) in primary packaging. The other heavy-metal coverage in Edition 5.7 is binary prohibition on intentional formulation (Other Prohibited Ingredients 3-metal list of Pb, Cr-VI, Se) or is indirect class-membership gating via the Carcinogens / Mutagens / Reproductive Toxins / Skin Sensitization / Aquatic Toxicity criterion families. Element-specific numerical concentration ceilings in the formulated product itself are not specified in Edition 5.7.
- Audit/verification methodology not in the standard text. The standard does not specify the analytical methods Green Seal uses in compliance verification for heavy-metal absence in formulated products or in primary packaging (e.g., ICP-MS, ICP-OES, GFAAS, XRF for packaging screening), nor LOD/LOQ targets, nor sample-prep digestion protocols. Those methods are in Green Seal’s internal certification audit procedures and are not reproduced in the published standard text.
- No Colorants clause. Unlike the sibling GS-52 (§ 3.21) and GS-37 (§ 2.1.4) standards, GS-8 Edition 5.7 does NOT have a Colorants criterion that names a 9-metal exclusion list (As, Cd, Co, Cr-VI, Pb, Mn, Hg, Ni, Se). HMI synthesis comparing the three Green Seal standards’ heavy-metal coverage should note that GS-8’s by-name metal set (Pb, Hg, Cd, Cr-VI in packaging + Pb, Cr-VI, Se in formulated product = 5 metals total) is narrower than GS-52’s and GS-37’s (which add As, Co, Mn, Ni via Colorants for a 9-metal total). Whether this reflects a deliberate Green Seal policy choice (e.g., that colorant prevalence in general-purpose / bathroom / glass / carpet cleaners is low enough not to warrant a separate clause) or an editorial gap in GS-8 is not stated in the Edition 5.7 text.
- Scope is household general-purpose / bathroom / glass / carpet only. The standard explicitly excludes specialty household cleaning products (Green Seal GS-52, sibling greenseal2022-gs52-specialty-household-cleaners); industrial and institutional general-purpose / restroom / glass / carpet cleaners (Green Seal GS-37, sibling greenseal2024-gs37-industrial-institutional-cleaners); industrial and institutional versions of specialty household products (Green Seal GS-53, not ingested); floor finish/strippers (Green Seal GS-40, not ingested); hand cleaners (Green Seal GS-41 for industrial/institutional, Green Seal GS-44 for household, both not ingested); cleaners/degreasers in production/maintenance applications (Green Seal GS-34, not ingested); air fresheners; paint remover/thinners; products containing enzymes sold in spray packaging; and antimicrobial pesticide products requiring EPA FIFRA registration. HMI sessions seeking Green Seal heavy-metal coverage for product splits outside household general-purpose / bathroom / glass / carpet should consult the named sibling standards.
- Withdrawn ASTM D4488-95 performance method. The general-purpose cleaner performance criterion (§ 2.1) references ASTM D4488-95 A5, which is the same withdrawn ASTM method noted in the sibling GS-52 page (Edition 2.6 footnote 5 acknowledges D4488 was withdrawn but remains “still the best available method”). Edition 5.7 GS-8 does not include the same footnote acknowledgment but cites the method by its ASTM D4488-95 designation in identical form. Conformity assessment relying on a withdrawn ASTM method is a noted procedural artefact shared across GS-8 and GS-52.
- B-tier qualitative source. Evidence tier B because: (i) the binding text of a third-party voluntary environmental certification standard, the operative current reference for Green Seal household general-purpose / bathroom / glass / carpet cleaner certification; (ii) no original measurements, no analytical methods used by Green Seal in compliance verification, no contamination values; (iii) the one explicit heavy-metal numerical limit (Packaging 100 ppm Pb + Hg + Cd + Cr-VI sum) is reproduced from the standard’s own clause text and is the binding ceiling for GS-8-certified products. B-tier reflects the standard’s binding-text status (matching the sibling GS-52 and GS-37 page tier rationale); A-tier is reserved for peer-reviewed occurrence/exposure studies, not for programme standards.
- No CAS numbers or compound enumeration for named metals. The Other Prohibited Ingredients and Packaging Heavy Metal Restrictions clauses name metals at the element level only (“lead”, “mercury”, “cadmium”, “hexavalent chromium”, “selenium”) without CAS numbers or compound-class enumeration. The Other Prohibited Ingredients clause uses “either in the elemental form or compounds” as a speciation qualifier on the three named metals (Pb, Cr-VI, Se). The Packaging clause does not carry that qualifier; “intentional introduction” is the operative test. HMI sessions interpreting metal coverage at the compound level must default to broad coverage absent narrower specification.
- Selenium named in Other Prohibited Ingredients clause but not in HMI’s metal taxonomy. Selenium is named in the § 3.10 Other Prohibited Ingredients clause of Edition 5.7 but is not currently a slug in HMI’s
wiki/metals/taxonomy. Selenium is therefore omitted from themetals:frontmatter array per CLAUDE.md Part 14 (taxonomy slugs only) and is surfaced as a missing-slug observation in Verification notes; if awiki/metals/selenium.mdpage were created, this standard would be a regulatory_context contributor (the same missing-slug pattern as the sibling GS-52 and GS-37 pages). - Inhalation LC50 units differ from GS-52. Edition 5.7 § 3.1 expresses the Acute Toxicity inhalation LC50 threshold as ≤20 mg/L at 1 hr, whereas the sibling GS-52 Edition 2.6 § 3.3 expresses the parallel threshold as ≤20,000 ppmV at 1 hr. The values 20 mg/L and 20,000 ppmV are different units of measurement (mass-per-volume vs parts-per-million-by-volume), not directly comparable without compound-specific molar-mass conversion. The numerical values are roughly comparable for typical small organic molecules (20 mg/L ≈ 5,000 ppmV at 100 g/mol for an ideal gas at 1 atm and 25°C, so 20,000 ppmV ≈ 80 mg/L at the same molecular weight) — the two standards’ acute-inhalation thresholds are NOT identical even at the same chosen units. HMI sessions interpreting Green Seal acute-inhalation thresholds across cleaning-product scopes should note this unit-and-value difference and not treat the two standards as imposing the same acute-inhalation ceiling.

Wiki pages this source may touch
- all-purpose-cleaners — within the GS-8 scope (§ 1.0 Scope; § 2.1 Standard Performance Requirement: ≥80% particulate soil removal per ASTM D4488-95, A5; Appendix 1 p. 22 included list “General-purpose cleaners”; Annex A defines General-Purpose Cleaner as “A product specifically marketed as suitable for cleaning common household surfaces. They do not include task-specific cleaners, such as scouring cleaners, toilet bowl cleaners, upholstery cleaners, laundry and dishwashing detergents, spot/stain removers, oven cleaners, furniture polish, or drain cleaners” p. 14). Routed as regulatory_context: both by-name heavy-metal mechanisms apply (Other Prohibited Ingredients 3-metal list; Packaging Heavy Metal Restrictions 100 ppm Pb+Hg+Cd+Cr-VI sum). General-purpose cleaners are the broadest in-scope category and have a dedicated performance criterion. CARB VOC limit 0.5% (effective 12/31/2012) applies per § 3.8 CARB table.
- bathroom-tub-tile-cleaners — within the GS-8 scope (§ 2.1 Standard Performance Requirement: ≥75% soil removal per ASTM D5343; Appendix 1 p. 22 included list “Bathroom cleaners”; Annex A defines Bathroom Cleaner as “A product used to clean hard surfaces in a household bathroom such as counters, walls, floors, fixtures, basins, tubs, and tile. This category does not include products specifically intended to clean toilet bowls” p. 13). Routed as regulatory_context. Same heavy-metal coverage. CARB VOC limit 1% (effective 12/31/2008) applies. Note: toilet bowl cleaners are explicitly EXCLUDED from the Bathroom Cleaner Annex A definition — they are not in GS-8 scope.
- carpet-cleaners — within the GS-8 scope (§ 2.1 Standard Performance Requirement: cleaning efficiency and resoiling resistance per AATCC, ASTM, IICRC, ISO, WoolSafe, Carpet and Rug Institute, or government-bid-evaluation laboratory methods; Appendix 1 p. 22 included list “Carpet cleaners”; Annex A defines Carpet Cleaner as “A product used for routine cleaning of household carpets and rugs. This category may include, but is not limited to, products used in cleaning by means of extraction, shampooing, dry foam, bonnet, or absorbent compound. It does not include products intended primarily for spot removal” p. 13). Routed as regulatory_context. Same heavy-metal coverage. CARB VOC limits 0.1% (dilutable, effective 1/1/2001) and 1% (ready-to-use, effective 12/31/2010) apply per § 3.8 CARB table. Note: spot-removal products are explicitly EXCLUDED from the Carpet Cleaner Annex A definition — those fall under sibling GS-52 specialty household scope.
- floor-cleaners-hard-surface — within the GS-8 scope (Appendix 1 p. 22 included list “Floor cleaning products”). Routed as regulatory_context. Same heavy-metal coverage. Edition 5.7 does not provide a separate § 2.1 performance criterion for floor cleaners specifically; floor cleaning products that fit the General-Purpose Cleaner Annex A definition (common household surfaces, not task-specific) would meet the § 2.1 general-purpose cleaner performance criterion (≥80% particulate soil removal per ASTM D4488-95, A5).
- window-glass-mirror-cleaners — within the GS-8 scope (§ 2.1 Standard Performance Requirement: ≥3 rating in each of HCPA method DCC 09 categories — soil removal, smearing, streaking; Appendix 1 p. 22 included list “Glass cleaners and mirror cleaning products”; Annex A defines Glass Cleaner as “A product used to clean windows, glass, and mirrored surfaces” p. 14). Routed as regulatory_context. Same heavy-metal coverage. CARB VOC limit 3% (effective 12/31/2012) applies per § 3.8 CARB table.
- lead — named in BOTH by-name heavy-metal clauses: Other Prohibited Ingredients (§ 3.10, p. 10, “lead … either in the elemental form or compounds”) and Packaging Heavy Metal Restrictions (§ 4.5, p. 11, among the four named metals subject to the 100 ppm sum ceiling). Routed as regulatory_context. Edition 5.7 maintains lead as the heavy metal with the broadest by-name coverage in GS-8, matching the parallel two-clause coverage in GS-52 Edition 2.6 (Prohibited Components + Packaging) and the parallel coverage in GS-37 Edition 7.8 (Prohibited Ingredients + Packaging Heavy Metal Restrictions). Note: GS-8 lacks the Colorants clause that gives Pb a third by-name appearance in GS-52 and GS-37.
- mercury — named in the Packaging Heavy Metal Restrictions clause (§ 4.5, p. 11, among the four-metal sum); NOT named in the Other Prohibited Ingredients clause (§ 3.10). Routed as regulatory_context. Note: GS-8 lacks the Colorants clause that gives Hg a second by-name appearance in GS-52 and GS-37; in GS-8, mercury appears only in the Packaging clause.
- cadmium — named in the Packaging Heavy Metal Restrictions clause (§ 4.5); NOT named in the Other Prohibited Ingredients clause (§ 3.10). Routed as regulatory_context. Same single-clause coverage as mercury within GS-8. Note: GS-8 lacks the Colorants clause that gives Cd a second by-name appearance in GS-52 and GS-37.
- chromium-hexavalent — named in BOTH by-name heavy-metal clauses: Other Prohibited Ingredients (§ 3.10, “hexavalent chromium … either in the elemental form or compounds”) and Packaging Heavy Metal Restrictions (§ 4.5, among the four-metal sum). Routed as regulatory_context. Edition 5.7 maintains the hexavalent-chromium speciation discipline; “chromium” without speciation does not appear by name in Edition 5.7.

metals: ["[[metals/lead]]", "[[metals/mercury]]", "[[metals/cadmium]]", "[[metals/chromium-hexavalent]]"]because every metal in this list is by-name named in at least one of the two by-name heavy-metal clauses (Other Prohibited Ingredients § 3.10; Packaging Heavy Metal Restrictions § 4.5). Selenium is named in the Other Prohibited Ingredients clause but is NOT in HMI’s metal taxonomy snapshot (nowiki/metals/selenium.md); selenium is therefore omitted from themetals:array per CLAUDE.md Part 14 (taxonomy slugs only) and surfaced as a missing-slug observation below — same handling as the sibling Green Seal pages.[[metals/chromium]]is NOT included because Edition 5.7 names “hexavalent chromium” specifically in both by-name clauses and does not name “chromium” without speciation; this matches the parallel GS-52 and GS-37 speciation discipline. 2-butoxyethanol, alkylphenol ethoxylates, phthalates, ozone-depleting compounds, optical brighteners, PFAS, bisphenol A, and chlorinated packaging material are organic-substance or class-membership additions to the Other Prohibited Ingredients / PFAS / Packaging clauses, not metals, and are not added to themetals:array. Themetals:array contains 4 metals (vs the sibling GS-52 page’s 8 metals and the sibling GS-37 page’s 9 metals) because GS-8 lacks the Colorants clause that adds As, Co, Mn, Ni, and Hg-second-clause to the sibling standards.ingredients: []because the source is a programme standard that names categories of substances (heavy metals, 2-butoxyethanol, alkylphenol ethoxylates, phthalates, ozone-depleting compounds, optical brighteners, PFAS, bisphenol A, chlorinated packaging material, titanium-dioxide-with-enzyme-exception) but not food or personal-care ingredients in HMI’s ingredient taxonomy (which is a food-ingredient taxonomy per the taxonomy snapshot). No new ingredient pages created (per skill hard constraints).productslists five existing product slugs covering the subset of GS-8 in-scope categories from Appendix 1 and § 1.0 Scope that have HMI taxonomy slugs: all-purpose-cleaners (general-purpose cleaners, § 2.1 with ASTM D4488-95 A5 ≥80% performance criterion); bathroom-tub-tile-cleaners (bathroom cleaners, § 2.1 with ASTM D5343 ≥75% performance criterion); carpet-cleaners (carpet cleaners, § 2.1 with AATCC/ASTM/IICRC/ISO/WoolSafe/CRI methods); floor-cleaners-hard-surface (floor cleaning products, Appendix 1 included list); window-glass-mirror-cleaners (glass cleaners and mirror cleaning products, § 2.1 with HCPA method DCC 09 ≥3 rating). All five slugs already exist inwiki/products/per the taxonomy snapshot; no new product pages created (per skill hard constraints). GS-8 Appendix 1 also includes “Products that contain microorganisms” and “Products that contain enzymes and are sold and/or designed for use in non-spray packaging” as included categories — these are formulation-type qualifiers rather than separate product categories and do not map to standalone HMI product slugs.matrices: []because the source is a multi-product-category programme standard without a single matrix focus. No new matrix slug is proposed.jurisdictions: [US]because Green Seal, Inc. is a US-based non-profit and GS-8 is a US voluntary environmental standard. Green Seal certifications are accepted internationally but the standard itself is published from a US programme.near_duplicates: []because the sibling Green Seal documents are the binding text of substantively different Green Seal standards: greenseal2022-gs52-specialty-household-cleaners covers specialty household cleaners (adhesive remover, boat cleaning, dish cleaning, motor vehicle cleaning, oven cleaning, etc.); greenseal2024-gs37-industrial-institutional-cleaners covers industrial and institutional general-purpose / restroom / glass / carpet cleaners; greenseal2009-gs37-version-comparison is a version-comparison artefact for GS-37 specifically. All three siblings have non-overlapping product scopes with GS-8 (household general-purpose / bathroom / glass / carpet). No near-duplicate found withinwiki/sources/.- Wiki/HMTc firewall (Part 2): the standard does not propose threshold values for HMTc certification, and this page’s Implications section does not propose any. GS-8 is referenced as the operative regulatory floor for household general-purpose / bathroom / glass / carpet cleaning products with explicit caveats that the standard text contains no occurrence data and no analytical methods for compliance verification. The 100 ppm packaging-metals sum ceiling and all other numerical thresholds in the standard (including the entire CARB VOC regulatory table) are reproduced as regulatory facts; this page makes no claim that any GS-8 numerical limit is a science-based HMI synthesis value or an HMTc threshold proposal. The Implications section’s comparison with the sibling GS-52 and GS-37 standards documents the structural and numerical parallels and differences between the three Green Seal standards (same Packaging 4-metal sum and 100 ppm ceiling; same Pb/Cr-VI/Se Prohibited Ingredients / Components 3-metal list; GS-8 and GS-37 share PFAS § 3.9 / § 2.1.10 but GS-52 does not; GS-52 and GS-37 share a 9-metal Colorants exclusion but GS-8 does not) as regulatory-context facts rather than as cross-source synthesis. No Part 2 drift risk.

Spray Protocol 2020), regulatory and standards bodies (Green Seal, FDA, EPA, EPA’s CompTox, CARB, OECD, WHO, EFSA, IARC, NTP, OSHA, IFRA, AISE, AATCC, IICRC, ISO, WoolSafe, Carpet and Rug Institute, ICCVAM, ECVAM), screening lists (EPA CompTox PFAS Master List; California Proposition 65; IARC, NTP, EPA IRIS, OSHA for carcinogen classifications; EFSA QPS; National Primary Drinking Water Standards 40 CFR Part 141), regulatory references (Code of Federal Regulations Title 16 Part 1700; Title 40 Part 157; Poison Prevention Packaging Act), and trade associations (HCPA, AISE) — all of which are scientific-method or regulatory references rather than commercial brand attribution to contamination values. Per CLAUDE.md Part 14 Exception 2 (scientific-method vendor/material names locked 2026-05-17), these are PERMITTED. The standard does not name any commercial brand of household cleaning product. No brand-firewall action required.

No numerical heavy-metal limits beyond the Packaging 100 ppm sum are stated in the source and none are claimed here. No quantitative content is invented or extrapolated.
- No new ingredient, product, or matrix pages were created during this ingest, per CLAUDE.md Part 10 and the skill’s hard constraints. All product slugs in the frontmatter are existing taxonomy.
- Missing-slug observations surfaced for Karen (not created by this ingest; for future Step 0 Lock or auto-stub decisions):
metals/selenium— named in the § 3.10 Other Prohibited Ingredients clause of Edition 5.7 (same one-clause coverage as in GS-52 Edition 2.6 Prohibited Components § 3.18 and GS-37 Edition 7.8 Prohibited Ingredients § 2.1.13). Selenium is not currently in HMI’s metal taxonomy snapshot. If awiki/metals/selenium.mdpage were created, this standard would be a regulatory_context contributor; cumulative selenium coverage across the four already-ingested Green Seal pages would be freq-5 (GS-8 Edition 5.7 one-clause coverage; GS-52 Edition 2.6 two-clause coverage; GS-37 Edition 7.8 two-clause coverage; GS-37 2008 Fourth Edition one-clause coverage; GS-37 2006 Third Edition one-clause coverage).regulations/green-seal-gs-8— the underlying GS-8 standard documented on this page. Green Seal’s household general-purpose / bathroom / glass / carpet cleaner standard is the operative regulatory document; noregulations/green-seal-*slugs currently exist.regulations/green-seal-gs-52— the Green Seal specialty household cleaner standard documented at greenseal2022-gs52-specialty-household-cleaners, explicitly referenced in GS-8’s Appendix 1 scope exclusions as the standard covering specialty household cleaning products.regulations/green-seal-gs-37— the Green Seal industrial and institutional general-purpose / restroom / glass / carpet cleaner standard documented at greenseal2024-gs37-industrial-institutional-cleaners, referenced in GS-8’s Appendix 1 scope exclusions.regulations/green-seal-gs-53— the Green Seal industrial and institutional specialty cleaning product standard, referenced multiple times in GS-8’s Appendix 1 scope exclusions as the I&I counterpart to GS-52 (household specialty). Not yet ingested in HMI; the GS-53 standard PDF is not present in the KADC folder.regulations/coneg-model-toxics-in-packaging-1989— same missing-slug observation as the sibling GS-52 and GS-37 pages (U.S. Coalition of Northeastern Governors Model Toxics in Packaging Legislation 1989; same 100 ppm sum of Pb+Hg+Cd+Cr-VI in packaging structural and numerical parallel).regulations/eu-directive-94-62-ec-packaging— same missing-slug observation as the sibling Green Seal pages (EU Directive 94/62/EC Article 11; same 100 ppm sum parallel).
- The PDF is 22 pages including the cover page, mission statement (p. 2), contents (p. 3), Foreword (p. 4), Acronyms (p. 5), main standard text (pp. 6-12), Annex A Definitions (pp. 13-17), Annex B Powders/Solids/Non-Aqueous Liquids (p. 18), Annex C Enzymes (p. 19), Annex D Microorganisms (pp. 20-21), and Appendix 1 Scope (p. 22). All 22 pages were read in full during ingest (pp. 1-10 in the first read pass, pp. 11-20 in the second, pp. 21-22 in the third). All four normative annexes and the informative appendix were read in full. The CARB regulatory limits table (split across pp. 9-10) was read in full and reproduced in Key numbers.
