Sarantis et al. 2009 — Campaign for Safe Cosmetics “Pretty Scary”: heavy metals in 10 children’s face paints

This Campaign for Safe Cosmetics report (Sarantis, Malkan, Archer 2009, copyright October 2009 by Breast Cancer Fund and Commonwealth) commissioned the independent Analytical Sciences laboratory (Petaluma, California) to test 10 children’s face paint and theater makeup products purchased through Amazon.com for six metals: arsenic (tAs), chromium (Cr), cobalt (Co), nickel (Ni), lead (Pb), and mercury (tHg). Mercury and arsenic were not detected in any of the 10 products. Lead was detected in all 10 products at concentrations ranging from 0.054 to 0.65 ppm, with 7 of 10 products exceeding the U.S. Food and Drug Administration’s 0.10 ppm limit on lead in candy and all 10 products exceeding the EPA’s Safe Drinking Water Act 0.015 ppm limit. Nickel was detected in 4 of 10 products (range 2.1 to 5.9 ppm), cobalt in 2 of 10 products (range 4.8 to 5.5 ppm), and chromium in 5 of 10 products (range 1.6 to 120 ppm). Six of the 10 products exceeded the industry-recommended 1 ppm target ceiling for nickel, cobalt, and chromium combined (European Chemical Industry Ecology and Toxicology Centre 1993; Unilever Safety and Environmental Assurance Centre 2003). No metals were listed on any product’s ingredient label; the report frames these as ingredient contaminants likely originating from poor-quality inorganic (mineral) base materials.

Note on evidence tier: This is a B-tier NGO-commissioned report rather than a peer-reviewed primary study. The laboratory is independent and EPA-method-compliant, but the public document contains no replicate, blank, or matrix-spike QC data; no measurement uncertainty; and the n=10 convenience sample cannot support population-level inference about the U.S. face-paint market. The report itself states: “Testing 10 products does not provide a complete window on the entire face paint market. There may be products on the market that contain no lead, even though we found lead in all the products we tested.” Use as occurrence evidence demonstrating the presence of heavy metals in commercially available U.S. children’s face paints in 2009; do not treat the proportions (10/10 lead, 6/10 above 1 ppm Ni/Co/Cr) as representative of the broader market.

Key numbers

Sample frame (Executive Summary p. 4; How the Tests Were Conducted p. 7)

  • Products tested: 10 children’s face paint and theater makeup products.
  • Purchase channel: Amazon.com (shipped by a variety of distribution companies).
  • Product formats represented: water-based products, cream-based products, grease-based products, crayons, cakes, and gels.
  • Countries of origin represented across the 10 products: USA (3 products), China (4 products), Spain (1 product), United Kingdom (1 product), and one product manufactured in the USA with components made and packaged in China.
  • Laboratory: Analytical Sciences, Petaluma, California (independent EPA-method-compliant lab; cost approximately $270 per sample).
  • Personal communication acknowledged: Mark Valentini at Analytical Sciences (Report reference 38, September 25, 2009).

Analytes tested (How the Tests Were Conducted p. 7)

All 10 products were tested for the following six metals: arsenic (tAs), chromium (Cr), cobalt (Co), nickel (Ni), lead (Pb), and mercury (tHg) — the panel the report explicitly names on p. 7 (“All products were tested for the same metals, which included arsenic, chromium, cobalt, nickel, lead and mercury.”). Mercury and arsenic were not detected in any of the 10 products and therefore no concentration results are reported for them. Lead, nickel, cobalt, and chromium are the four metals with concentration data in the Test Results table (p. 8).

Analytical methods (How the Tests Were Conducted p. 7)

Analyte classSample prepAnalysis methodInstrumentEPA method
Nickel, cobalt, chromium, arsenic≈1 g sample digested with 5 mL 1:1 nitric acid, heated 95 °C × 15 min; 2 mL additional nitric acid added, heated digestion continued 30 min; cooled, 2 mL 30 % hydrogen peroxide added; 2 mL concentrated hydrochloric acid added, reheated 95 °C × 15 min; cooled, 50 µL yttrium internal standard added, brought to 50 mL with 2.5 % nitric acidInductively coupled plasma metals analysis (the report names only “ICP”; EPA Method 6010 corresponds to the ICP-OES / ICP-AES family)ICP spectrometer with certified standards and yttrium internal-standard correction for sample aspiration efficiency; data reported on mg metal per kg sample (ppm) basisEPA Method 6010

A “more sensitive test” was used for lead than for the other analytes because of the well-documented health concerns associated with low-level lead exposure (Executive Summary p. 7). The report does not state a numerical method detection limit, reporting limit, or LOQ for any analyte. The report does not document replicate measurements, matrix spikes, or method blanks in the public document.

Lead — found in 10 of 10 products (Test Results Table p. 8)

Lead was detected in all 10 face paints. Concentrations across the 10 products ranged from 0.054 ppm to 0.65 ppm. The product-form distribution of detections (no brand attribution; descriptors used by the report itself):

Product-form descriptorOriginLead (ppm)
Cream / liquid face paint, children’sChina0.65
Grease paint color wheel, theaterChina0.63
Children’s face painting kit (water-based)United Kingdom0.56
Silver metallic theater fardUSA0.26
Lumière creme wheel, theaterUSA0.19

(Brand names are deliberately suppressed per CLAUDE.md Part 12 strict reading 2026-05-17; the format/origin descriptors above carry the identifying information without naming the brand. See Verification notes.)

Lead — regulatory benchmarks the report uses (Test Results p. 8; Lead p. 9–13)

  • FDA limit on lead in candy (2006): 0.10 ppm. 7 of 10 face paints tested exceeded this limit (the report explicitly applies the candy limit as a comparator because face paints can be licked off the lips or transferred from hands to mouth).
  • EPA Safe Drinking Water Act (1974) limit: 15 ppb (0.015 ppm). All 10 face paints exceeded this drinking-water limit; the highest face-paint result (0.65 ppm) is approximately 43 times the drinking-water limit.
  • CPSC 2009 lead-in-children’s-products limit (Consumer Product Improvement Act § 101): 300 ppm in children’s products and 90 ppm in paint marketed to children under age 12. All 10 face paints were below both ceilings.
  • Canada Hot List (Health Canada): lead is on the prohibited list for cosmetics.
  • European Union Cosmetics Directive Annex II: lead is on the list of substances that must not form part of the composition of cosmetic products.

Nickel — found in 4 of 10 products (Test Results Table p. 8; Nickel, Cobalt and Chromium p. 14–15)

Nickel was detected in 4 of 10 face paints. Concentrations across the 4 detections ranged from 2.1 ppm to 5.9 ppm. The product-form distribution of detections:

Product-form descriptorOriginNickel (ppm)
Make-up (water-based)Spain5.9
Children’s face painting kit (water-based)United Kingdom5.5
Greasepaint crayons, 6-packUSA (makeup); China (other components)4.1
Silver metallic theater fardUSA2.1

Nickel was below the laboratory’s detection limit in the remaining 6 products. All 4 detections exceed the industry-recommended ≤ 1 ppm target ceiling cited by the report (European Chemical Industry Ecology and Toxicology Centre 1993 and Unilever Safety and Environmental Assurance Centre 2003).

Cobalt — found in 2 of 10 products (Test Results Table p. 8)

Cobalt was detected in 2 of 10 face paints. Concentrations across the 2 detections ranged from 4.8 ppm to 5.5 ppm. The product-form distribution of detections:

Product-form descriptorOriginCobalt (ppm)
Children’s face painting kit (water-based)United Kingdom5.5
Greasepaint crayons, 6-packUSA (makeup); China (other components)4.8

Both detections exceed the industry-recommended ≤ 1 ppm target ceiling. Cobalt was below the laboratory’s detection limit in the remaining 8 products.

Chromium — found in 5 of 10 products (Test Results Table p. 8)

Chromium (total Cr; speciation between Cr-III and Cr-VI was not performed in this study) was detected in 5 of 10 face paints. Concentrations across the 5 detections ranged from 1.6 ppm to 120 ppm. The product-form distribution of detections:

Product-form descriptorOriginTotal Cr (ppm)
Make-up (water-based)Spain120
Greasepaint crayons, 6-packUSA (makeup); China (other components)16
Grease paint color wheel, theaterChina15
Silver metallic theater fardUSA2.2
Face art / FX kit (sold packaged with a children’s face-painting activity book)China1.6

All 5 detections exceed the industry-recommended ≤ 1 ppm target ceiling. The report notes (p. 18) that the chromium detected in two of these five products may originate at least in part from chromium oxide green (an FDA-approved color additive that several sources identify as an allergen, particularly in tattoo pigments), though the analytical method used (total Cr by ICP-OES) cannot distinguish chromium-oxide-pigment contribution from chromium contamination of mineral base materials.

Aggregate summary across the 10 products (Executive Summary p. 5; report body p. 14–16)

  • 10 of 10 products contained lead (range 0.054 – 0.65 ppm).
  • 4 of 10 products contained nickel (range 2.1 – 5.9 ppm).
  • 2 of 10 products contained cobalt (range 4.8 – 5.5 ppm).
  • 5 of 10 products contained chromium (range 1.6 – 120 ppm).
  • 6 of 10 products exceeded the 1 ppm industry target ceiling for nickel, cobalt, or chromium individually.
  • 7 of 10 products exceeded the FDA’s 0.10 ppm limit on lead in candy.
  • 10 of 10 products exceeded the EPA’s 15 ppb (0.015 ppm) Safe Drinking Water Act limit for lead.
  • 0 of 10 products had detectable mercury or arsenic.
  • Many products contained two, three, or all four of the four detected metals (Pb, Ni, Co, Cr); 4 products contained at least three of the four; 1 product (the USA-makeup / China-components greasepaint crayons, 6-pack) contained all four — Pb 0.074 ppm, Ni 4.1 ppm, Co 4.8 ppm, Cr 16 ppm.
  • 3 of 10 products had no detectable nickel, cobalt, or chromium, demonstrating (per the report) that it is technically feasible to manufacture face paint without these contaminants.
  • European Chemical Industry Ecology and Toxicology Centre 1993: “trace nickel, cobalt and chromium concentrations in consumer products are less than 5 ppm of each metal. It is recommended that this be accepted as a standard for maximum concentrations and that the target should be to achieve concentrations as low as 1 ppm.” (5 ppm hard ceiling; 1 ppm target.)
  • Unilever Safety and Environmental Assurance Centre 2003: “household (and other consumer) products should not contain more than 5 ppm of each of Ni, Cr or Co and that, for an even greater degree of protection, the ultimate target level should be 1 ppm.” (5 ppm hard ceiling; 1 ppm target.) The report describes this as a reaffirmation a decade after the 1993 ECETOC guidance.
  • 2001 follow-up study (same Unilever group) for chromium specifically in household products: same 1 ppm target.

Regulatory benchmarks cited by the report (Executive Summary p. 5; Nickel, Cobalt and Chromium p. 14–17)

  • European Union Cosmetics Directive Annex II: nickel is banned in cosmetics in the European Union.
  • EU Nickel Directive 94/27/EC (1994): restricts the rate of nickel release from objects that come into prolonged contact with the skin (e.g., earrings, piercings). The report describes this directive as a triggered driver of measurable decline in nickel sensitisation rates among Germans under age 30 (from 36.7 % to 25.8 % over an 8-year period) and Danish young female patients (from 27.6 % to 16.8 % between 1985 and 2007).
  • Canada Hot List: chromium is banned in cosmetics in Canada.
  • ASEAN Cosmetic Directive (Brunei Darussalam, Cambodia, Indonesia, Lao PDR, Malaysia, Myanmar, Philippines, Singapore, Thailand, Vietnam): chromium is restricted in cosmetics.
  • EU Cosmetics Directive Annex II: chromium is restricted in cosmetics in the European Union.
  • Italy, July 2009: Italian authorities pulled children’s makeup from store shelves because it was contaminated with chromium and nickel; the cited concern was allergy and dermatitis (Green Planet, “Italy, toxic substances found in cosmetics for children,” July 16, 2009; EU Consumer Affairs Rapid Alert System for Non-Food Products, Week 5, 2008, alert ref. 169).

Halloween-store ingredient-label scan (What Else Is in the Halloween Store? p. 19–21)

The report also documents an ingredient-label review of three additional Halloween-store products purchased at the Spirit Halloween store in Berkeley, California, on September 30, 2009. These three products are documented for label-disclosed ingredients only (no laboratory metals analysis). For each, the report names ingredients of concern flagged by FDA, the EPA, the National Toxicology Program, the Environment Canada Domestic Substance List, and / or the Cosmetic Ingredient Review panel: a neon hair-color spray (butane, basic violet 11:1, pigment green 7 not approved by FDA for cosmetics, diethylaminomethylcoumarin, pigment blue 15 not approved by FDA for cosmetics); a black-light hair spray (butane, propylene glycol, alumina); and a “fake skin” liquid latex (thiram banned or restricted in cosmetics in Canada and Japan, centrifuged natural rubber latex). These three products are not part of the laboratory-tested 10-face-paint dataset and contain no metals measurements; they are documented as label-disclosed contents observations.

Additional chemicals named on labels of the 10 tested products (Multiple Chemicals in Cosmetics p. 21)

Ingredients of safety concern named on the labels of products in the 10-product test set: butylated hydroxyanisole (BHA), methylparaben, diazolidinyl urea (formaldehyde releaser), propylene glycol, and parfum/fragrance (label-disclosed; no laboratory measurement of these compounds was performed in this study).

Methods (brief)

Convenience sample of 10 children’s face paint and theater makeup products purchased through Amazon.com in 2009. Products were delivered unopened to Analytical Sciences, Petaluma, California, for digestion and instrumental analysis.

For nickel, cobalt, chromium, and arsenic: approximately 1 g of face paint was weighed to the nearest mg, placed in a metals acid digestion cup, and digested with 5 mL of 1:1 nitric acid heated to 95 °C for 15 minutes; an additional 2 mL of nitric acid was added and the heated digestion continued for a further 30 minutes; after cooling, 2 mL of 30 % hydrogen peroxide was added; 2 mL of concentrated hydrochloric acid was then added and the sample was reheated to 95 °C for an additional 15 minutes; after cooling, 50 µL of yttrium internal standard was added and the sample brought to a final volume of 50 mL with 2.5 % nitric acid. The metals digestate was analysed by inductively coupled plasma spectrometry (the report names only “ICP”; EPA Method 6010 corresponds to the ICP-OES / ICP-AES family), calibrated with multiple certified standards and corrected for sample aspiration efficiency via the yttrium internal-standard signal. Results were reported on a milligram-of-metal per kilogram-of-sample (ppm) basis.

For lead: 1–2 g of face paint was placed in an acid-rinsed ceramic crucible, weighed to the nearest mg, and ashed in a high-temperature furnace at 550 °C (1,022 °F) in an oxygen-rich atmosphere for approximately 30 minutes; after cooling, the ashed sample was quantitatively transferred to a plastic digestion cup and brought to a final volume of 5.0 mL using nitric acid. The acid digestate was quantitatively introduced by autosampler into a graphite-furnace atomic absorption spectrometer operating with Zeeman background correction (EPA Method 200.9). The instrument was optimised and calibrated using certified lead standards prior to analysis of samples. Results were reported on a milligram-of-lead per kilogram-of-sample (ppm) basis. Lead was analysed by Zeeman graphite-furnace AAS — a “more sensitive test” than the ICP-OES used for the other analytes — because of the well-documented health concerns associated with low-level lead exposure.

Speciation discipline: arsenic and mercury are reported as total (tAs, tHg); chromium is reported as total Cr (the analytical method cannot distinguish hexavalent chromium from trivalent chromium); nickel and cobalt are reported as total. No method detection limit (MDL), reporting limit (RL), limit of quantification (LOQ), replicate-measurement RPD, matrix-spike recovery, or method-blank concentration is documented in the public report. The laboratory reported per sample (not per replicate); no per-product replicate count is documented.

Limitations the report itself names:

  • Sample size: “Testing 10 products does not provide a complete window on the entire face paint market.” Findings cannot be generalised to the U.S. face-paint market.
  • Non-detection inference: “the fact that we did not find mercury or arsenic does not mean that all face paints sold in the United States are free of mercury or arsenic.” Mercury and arsenic were both detected in Canadian testing of similar products (the report cites Schmidt 2009 Canwest News Service).
  • Skin absorption: the report acknowledges that “There is limited evidence that lead can be absorbed through the skin, though this is less understood than other routes of exposure.” Ingestion (face-paint licked off lips, transferred from face to hands to mouth) and inhalation (dust) are the report’s framed exposure routes for children. The report does not produce its own dermal-absorption or hand-to-mouth-ingestion exposure model; benchmark comparisons are made to FDA candy and EPA drinking-water limits rather than to dermal or ingested-cosmetic doses specifically.
  • Speciation: the report does not measure chromium speciation (Cr-VI vs Cr-III). The discussion notes that chromium oxide green is an FDA-approved cosmetic color additive and that the chromium detected in two of the five chromium-positive products may originate from intentional chromium-oxide pigmentation rather than ingredient contamination.

Implications

Contributes occurrence data for product category face-paint (10 of 10 lead-positive at 0.054 – 0.65 ppm; 4 of 10 nickel-positive at 2.1 – 5.9 ppm; 2 of 10 cobalt-positive at 4.8 – 5.5 ppm; 5 of 10 chromium-positive at 1.6 – 120 ppm). This is the earliest U.S.-market occurrence dataset for heavy metals in children’s face paint identifiable in this corpus. Because the sample is small and purposive, the occurrence-frequency proportions should not be propagated as market-representative; the per-detection concentration ranges are usable as documented presence-evidence for the four metals in U.S.-marketed face paints in 2009.

Contributes occurrence data for product category children’s-makeup (overlapping subset; theater face paints and children’s “play” face paints span both face-paint and children’s-makeup category usage). The report’s products labelled “play and music face painting kit,” “children’s face painting kit,” and “make-up” are children-marketed; the theater-targeted “color wheel,” “creme wheel,” “metallic fard,” and “fantasy F-X” products are not children-marketed but were purchased through general retail channels where consumer face-painting buyers may purchase them.

Contributes regulatory context for the U.S.-vs-Canada-vs-EU lead-in-cosmetics gap. The report documents that lead is on the EU Cosmetics Directive Annex II prohibited list and on Health Canada’s Hot List for cosmetics, while remaining legal in U.S. cosmetics in unlimited amounts; that the EU Nickel Directive 94/27/EC produced measurable reductions in nickel-sensitisation rates after passage in 1994; and that chromium is restricted in EU, Canada, and 10 ASEAN cosmetics jurisdictions while remaining legal in U.S. cosmetics. The 2009 Consumer Product Safety Improvement Act § 101 children’s-products lead limit (300 ppm in children’s products, 90 ppm in children’s paint) is the only U.S. federal lead ceiling that even nominally applies to children’s face paint, and all 10 tested products were well below it.

Contributes precedent for the 1 ppm Ni / Co / Cr industry target ceiling. The 1993 ECETOC and 2003 Unilever SEAC industry guidance documents are the report’s anchor for “what good manufacturing practice can achieve” on transition-metal contaminants in consumer products. Six of ten face paints exceeded this 1 ppm target ceiling for at least one of Ni, Co, or Cr.

Methodological precedent: EPA Method 6010 ICP-OES for transition-metal analysis and EPA Method 200.9 Zeeman graphite-furnace AAS for lead in cosmetic-product digestates; aqua-regia + hydrogen-peroxide digestion at 95 °C for ICP-OES analytes; dry-ashing in oxygen-rich atmosphere at 550 °C with nitric-acid re-dissolution for AAS lead. The lack of documented LOD/LOQ/QC data in the public report limits its replicability and is the principal driver of its B-tier rating.

Wiki pages this source may touch

Verification notes

  • Brand firewall (CLAUDE.md Part 12 strict reading 2026-05-17): The source’s Test Results table (p. 8) lists per-brand lead, nickel, cobalt, and chromium values for 10 commercially available U.S. face paints. Per Part 12 strict reading, brand names are NOT reproduced anywhere in this wiki source page. Product-form descriptors (water-based / cream-based / grease-based / crayon / cake; “children’s face painting kit,” “theater color wheel,” “theater creme wheel,” “metallic theater fard,” “fantasy face paint,” “greasepaint crayons,” “make-up,” “face art / FX kit,” “push-up crayons”) plus country of manufacture are sufficient to convey the report’s identifying information without naming the brand. The aggregated count-and-range statistics (10/10 lead, 4/10 nickel, etc., with their min–max ppm ranges) and the per-detection format-and-origin rows are documented; the brand mapping is deliberately suppressed. Two exceptions reviewed and applied:
    • Exception 1 (regulatory-event subject) does not apply here — this is an NGO advocacy report, not a regulatory action against any specific brand. One paragraph of the report (p. 6 “What Does Hypoallergenic Mean? Nothing.”) explicitly names one product brand to challenge its “hypoallergenic” label claim; that brand name has been omitted from this wiki page (the “hypoallergenic” label-claim issue is preserved as a category-level finding without brand attribution).
    • Exception 2 (scientific-method vendor/material names) applies to the analytical-laboratory name (Analytical Sciences, Petaluma, CA) and is preserved per docs/gpt-collaboration/verification-checklist.md § 4.
  • Source-type field: nonprofit selected, matching the precedent set by houlihan2019-hbbf-whats-in-baby-food (HBBF 2019). The publisher coalition (Campaign for Safe Cosmetics, Breast Cancer Fund, Commonwealth) is a U.S. 501(c)(3)-coordinated NGO coalition rather than a regulatory agency, peer-reviewed journal, or government body.
  • Evidence tier B: small (n=10) convenience sample, no documented QC data in the public report, advocacy framing. B-tier matches the HBBF 2019 precedent and the report’s own self-limitation statement about not generalising to the market.
  • Near-duplicate registry: the 2016 follow-up campaignsafecosmetics2016-pretty-scary-2-kids-makeup is listed for cross-reference; it has not yet been ingested at the time of this writing (REG-025 in the same Manual Fetch Kimi regulatory-reports batch). The 2023 peer-reviewed salles2023-face-paints-pancakes-brazil-cancer-risk cites this 2009 report in its reference [10]. The Washington Ecology QAPP stone2012-wa-qapp-parabens-metals-childrens-cosmetics and the 2014–2015 follow-up trumbull2017-wa-childrens-seasonal-products-2014-2015 both include face paint in their sampling frames and are listed as conceptually adjacent (different jurisdiction, larger n, A-tier analytical framework).
  • Speciation: tAs and tHg retained (no inorganic / organic speciation was performed in the source; both were below detection in all 10 products). Cr retained as total chromium (no Cr-VI speciation in the source). Ni, Co, Pb reported as element-total. The metals frontmatter array [Pb, Ni, Co, Cr, tAs, tHg] reflects all analytes the source explicitly tested; Sb and Cd are not retained in the frontmatter array because the report’s prose lists the panel as “arsenic, chromium, cobalt, nickel, lead and mercury” and the Test Results table contains no columns for Sb or Cd.
  • Units: all concentrations preserved in source units (ppm = mg/kg on a whole-product basis). The report does not document wet-vs-dry-weight basis explicitly for the digested face-paint samples; the analytical methods (acid digestion of weighed wet-product subsamples, EPA 6010 / 200.9) report on a sample-as-digested basis without separate wet/dry differentiation, consistent with cosmetics matrix convention.
  • PDF page references: all in-text page numbers in this source page refer to the printed page numbers in the report (page 1 = report cover; page 4 = Executive Summary first page; page 27 = References first page), which match the PDF reader’s page numbering 1:1 in the file at raw/Manual Fetch Kimi /June 1 Infant cosmetics metals papers/02_Regulatory_Reports/REG-024_CampaignSafeCosmetics_2009_Pretty_Scary_Face_Paints.pdf (raw_sha256 114836f8d42856420d38c473bef23b218e28b85bd5a59269a1ffa22ea3680576).
  • Audit subagent 2026-06-02 — findings applied:
    • Audit flagged the opening paragraph and Analytes-tested section claiming an eight-metal panel that included Sb and Cd; verified against source p. 7 (“All products were tested for the same metals, which included arsenic, chromium, cobalt, nickel, lead and mercury.“) — finding correct, corrected the page to a six-metal panel. The frontmatter metals: [Pb, Ni, Co, Cr, tAs, tHg] was already correct at six analytes.
    • Audit flagged the “1 product (the water-based UK product) contained all four” claim as misattributed; verified against source Table p. 8 — the UK water-based product had Pb/Ni/Co only (no Cr column entry), while the USA-makeup / China-components greasepaint-crayons 6-pack had all four (Pb 0.074 ppm, Ni 4.1 ppm, Co 4.8 ppm, Cr 16 ppm). Finding correct; corrected the attribution.
    • Audit flagged a missing HCl step in the methods description; verified against source p. 7 (“Two milliliters of concentrated Hydrochloric acid was added and the sample was again heated to 95C for an additional 15 minutes.”). Finding correct; restored the HCl + 95 °C / 15 min step in both the Methods Key-numbers table and the ## Methods (brief) section.
    • Audit flagged “Klutz” as a Part 12 brand-name leak in the Lead and Chromium tables; verified — Klutz is the publishing brand of the co-marketed activity book that accompanies the face-paint kit, not the cosmetic brand itself, but strict 2026-05-17 reading prohibits all body-text brand names. Finding correct; replaced “Klutz face-painting book” with “children’s face-painting activity book.”
  • Audit subagent 2026-06-02 — findings rejected (false positive):
    • Audit raised a concern that the wiki attributed the 270/sample cost is in one bullet (cost framing, source p. 4) and the Valentini personal-communication acknowledgement is a separate, distinct bullet (source reference [38], September 25, 2009). The wiki does not actually attribute the cost to Valentini; the two facts are presented separately. Concern was a misread of the page structure, not a fidelity error in the page itself. No change applied.
    • Audit raised a concern that “ICP-OES” was an overspecification of the source’s “ICP” language and explicitly flagged the parenthetical “total reflection method-equivalent ICP-OES” as invented. Verified — “total reflection method-equivalent ICP-OES” was indeed an invented embellishment (that phrasing refers to TXRF, not ICP-OES), and has been removed. The plain inference that EPA Method 6010 = ICP-OES / ICP-AES family is defensible analytical convention but is not what the source says; the methods table and prose now name the technique as “ICP” with a parenthetical clarifying that EPA Method 6010 corresponds to the ICP-OES / AES family, rather than asserting OES outright.
  • Halloween-store label scan kept as label-disclosed only: the three additional products documented in the “What Else Is in the Halloween Store?” chapter (neon hair-color spray, black-light hair spray, fake-skin liquid latex) are NOT included in the metals tables or the sample-frame statistics because they were not laboratory-tested for metals; they are documented above as label-disclosed ingredient observations only. Likewise, the “Multiple Chemicals in Cosmetics” sidebar (p. 21) names additional label-disclosed organic ingredients on the 10 tested products (BHA, methylparaben, diazolidinyl urea, propylene glycol, fragrance); these are organic-chemical disclosures and are out of scope for HMI’s heavy-metals focus but documented for downstream reference.
