Malaysian Association of Standards Users 2016 — Comparative testing of pacifiers and sippy cups for bisphenol A, phthalates, and nitrosamines (Malaysia)
This Malaysian Association of Standards Users (Standards Users) comparative consumer-testing report documents the survey of eight infant-contact products (six pacifiers/soothers, one sippy cup, one 3-in-1 nursing cup) purchased from Malaysian retail in 2016 and submitted to two accredited laboratories for bisphenol A (BPA), six phthalate esters, and ten N-nitrosamine compounds. All three analyte classes were reported as Not Detected across all eight samples at the laboratories’ stated limits of reference (BPA limit of detection 0.5 ng/mL; phthalates limit of reference 0.5 and 5 mg/kg; nitrosamines limit of reference 0.5 and 1 mg/kg). The report does not test heavy metals in the eight samples. Heavy metals enter the report only as regulatory context: Tables 1 and 2 transcribe the soluble-element migration limits from Denmark (based on EN 71-3, applied to soothers) and from Malaysian standard MS 1156:1989 (Specification for Babies’ Pacifiers), and the body discusses the absence of Malaysian regulatory coverage for pacifiers, sippy cups, replacement nipples, teethers, and infant-food receptacles for nitrosamine/phthalate/BPA content. The HMI value of this source is therefore (i) a B-tier confirmation of zero BPA/phthalate/nitrosamine detections in an eight-product Malaysian retail sample of pacifiers and sippy cups (relevant to infant-contact product context, though outside the HMI analyte panel), and (ii) a regulatory-context transcription of the Danish EN 71-3 and Malaysian MS 1156:1989 element-migration limits relevant to pacifier and soother heavy-metals regulation.
Key numbers
Sample frame
- Products purchased and tested: 8 (Section 3.3, Table 4 p. 10-11, Table 5 p. 13-14).
- Pacifiers/soothers: 6 (samples No. 1-6; Section 3.3, Table 4).
- Sippy cup: 1 (sample No. 7; Section 3.3, Table 4).
- 3-in-1 nursing cup: 1 (sample No. 8; Section 3.3, Table 4).
- Unit price range: RM 2.70 (Silicone Soother with Cover, sample No. 5) to RM 7.60 (3-in-1 Nursing Cup, sample No. 8) (Table 4 p. 10-11).

Regulatory context transcribed in the report
Table 1 — Danish soother element-migration limits, based on EN 71-3 (Section 2.4, p. 3):
| Element | Limit (mg/kg = ppm) |
|---|---|
| Antimony, Sb | 15 |
| Arsenic, As | 10 |
| Barium, Ba | 100 |
| Cadmium, Cd | 20 |
| Lead, Pb | 25 |
| Chromium, Cr | 10 |
| Mercury, Hg | 10 |
| Selenium, Se | 100 |
Report note: “The analytical method specified in EN 71-3 has been applied in this standard to soothers. The limits set account for the prolonged sucking of a teat in the mouth.”
Companion Danish nitrosamine limits (Section 2.4, p. 3):
| Compound class | Limit (mg/kg = ppm) |
|---|---|
| N-Nitrosamines | 0.01 |
| N-Nitrosatables | 0.1 |
Table 2 — Malaysian Standard MS 1156:1989 (Specification for Babies’ Pacifiers) soluble-element limits (Section 2.5, p. 3):
| Element | Limit (mg/kg = ppm) |
|---|---|
| Antimony, Sb | 250 |
| Arsenic, As | 100 |
| Barium, Ba | 500 |
| Cadmium, Cd | 100 |
| Chromium, Cr | 250 |
| Lead, Pb | 100 |
Malaysian volatile-nitrosamine limit (Section 2.5, p. 4; ref. MS 1312:1993 dichloromethane extraction method): “all rubber pacifiers or rubber component parts of pacifiers including any filling in the teat shall not contain in excess of 30 ppb total volatile nitrosamine content, neither shall the contain in excess of 15 ppb of any one volatile nitrosamine.”
US CPSC nitrosamine limit (Section 2.4, p. 3): “the limit for nitrosamines in nipple not exceeding 20 ppb of total nitrosamines.”
Table 3 — Status of regulations and standards across jurisdictions (Section 2.6, p. 4): Malaysia (MS 1156:1989 and MS 1312:1993, status: “Not regulated”), Australia (AS 2432-2009 Baby Dummies, status: Mandatory), New Zealand (information not available), Canada (Hazardous Products (Pacifiers) Regulations, status: Mandatory), Denmark (EN 12868 nitrosamine method, EN 14060 soothers, DS/EN 1400-3 chemical requirements, status: Mandatory), Fiji (Trade Standards and Quality Control Decree banning phthalate plasticizers in toys and childcare items, status: Mandatory), United States (ASTM F1313-90(2011) volatile N-nitrosamine specification for rubber nipples on pacifiers, status: Mandatory).
Regulatory background discussed (Section 1, p. 1)
- US CPSC 2010-07-20 recall: 45,000 baby pacifiers recalled by the US Consumer Product Safety Commission for choking and aspiration hazard (nipple separation, oversize handle, undersize mouth guard, missing ventilation holes).
- November 2009 CPSC recall: an earlier branded infant pacifier recalled for similar design-flaw choking risk.
- Malaysian BPA ban context (Section 3, p. 5): Malaysia “recently imposed ban on BPA in plastic feeding bottles (which takes effect in March 2012)“. The report flags that the ban does not cover sippy cups used for children, motivating the BPA test scope.
Background literature cited
- Nitrosamines, baby bottle nipples and pacifiers (Section 2.2, p. 2, footnote 2): “Reduction in levels of volatile N-nitrosamines in rubber nipples for babies’ bottles,” Food and Chemical Toxicology Volume 23, Issue 11, November 1985, pages 991-993. Reported finding: “out of 16 samples of baby bottle nipples and children pacifiers tested, 81% of the products did not meet the Dutch standards which was based on aqueous extraction method. And if it was compare to the U.S regulations, 37.5% of the products would be banned.”
- Non-volatile nitrosamines (Section 2.2, p. 2, footnote 3): Sen NP, Seaman SW, Kushwaha SC — “Determination of non-volatile N-nitrosamines in baby bottle rubber nipples and pacifiers by high-performance liquid chromatography-thermal energy analysis”, PubMed. Reported finding: “Eighteen out of twenty four samples analyzed were found to contain varying levels of N-nitrosodibenzylamine,” a carcinogenic compound.
Methods (brief)
The report names two laboratories but redacts both lab identities in the published PDF:
- Laboratory 1 (named-but-redacted): phthalates and nitrosamines, USEPA Method 3570 (extraction) and USEPA Method 8270 C (GC-MS determination of semivolatile organics). Limits of reference 0.5 mg/kg for most compounds; 1 mg/kg for N-nitrosopyrrolidine; 5 mg/kg for bis(2-ethylhexyl) phthalate (DEHP).
- Laboratory 2: bisphenol A; reported as “Centre for Xenobiotics Studies” with parent-institution name redacted. Limit of detection 0.5 ng/mL.
Sample collection: eight retail-purchased products from Malaysian retail in 2016. The report does not describe sample preparation, replicate count, or QC procedures beyond identifying the methods and labs; per the report’s own Section 3.2 limitation, the sample is small and not representative.
No heavy metal analysis was performed on the eight samples. The element migration limit tables (Tables 1 and 2) are regulatory transcriptions, not measurements.
Implications
-
HMTc audit implications. For HMTc work on Pacifiers and sucking/teething aids (Category 9, Row 4) and Sippy cups and toddler drinkware components (Category 9, Row 3), this source contributes the Danish EN 71-3-based element-migration regulatory ceiling (Sb 15, As 10, Ba 100, Cd 20, Pb 25, Cr 10, Hg 10, Se 100 ppm) and the Malaysian MS 1156:1989 soluble-element ceiling (Sb 250, As 100, Ba 500, Cd 100, Cr 250, Pb 100 ppm) as named regulatory inputs to the lowest-applicable-regulatory-cap test in the Standards Workbench. The Danish limits are substantially tighter than the Malaysian limits across the panel — by a factor of 4 (Pb), 5 (Cd, Cr), and 10 (Sb, As) — and EN 71-3 is the operative European reference for prolonged-sucking exposure on soothers. The source contributes no occurrence data on the eight samples for these metals; the samples were tested only for BPA, phthalates, and nitrosamines.
-
Occurrence data contribution. Zero. The eight-sample retail survey did not measure heavy metals. The all-ND BPA/phthalate/nitrosamine finding is outside the HMI analyte panel and is recorded here as the paper’s primary finding for traceability but does not populate any metal
contamination_profile. -
Regulatory landscape. Table 3 (Section 2.6) is a useful jurisdiction-level snapshot of pacifier/soother chemical regulation as of 2016: Mandatory in Australia, Canada, Denmark, Fiji, US (nitrosamine-specific); Not regulated in Malaysia (the report’s policy ask is for the Malaysian Department of Standards to revise MS 1156:1989 and for the Ministry of Health to extend the BPA ban to pacifiers, sippy cups, replacement nipples, teethers, and infant food receptacles).
-
App. Not directly relevant to ingredient
contamination_profiledata. Relevant to a future infant-product screening surface that explains why pacifiers and sippy cups are a regulated category under EN 71-3 (Europe) and ASTM F1313 (US nitrosamines) but were unregulated for chemical migration in Malaysia as of the report’s publication. -
Courses. Useful as a worked example of NGO comparative consumer testing as a regulatory-advocacy lever: a small retail-purchased sample (n=8), accredited laboratory methods (USEPA 3570/8270 C), all-ND findings, and the report’s resulting policy recommendation to the Department of Standards Malaysia and the Ministry of Health.

Verification notes
- Source identification. Malaysian Association of Standards Users. 2016. Comparative Testing: Baby Pacifier and Sippy Cups. Petaling Jaya, Malaysia. NGO comparative consumer-testing report; institutional author (Standards Users, FOMCA-affiliated Malaysian consumer-standards body). Report is undated in the document body; the filename year tag “2016” and the report’s framing of the Malaysian BPA ban as having taken effect in March 2012 (“currently the Ministry of Health has issued a ban on BPA in plastic feeding bottles effective March 2012”) plus references to the 2010 CPSC recall locate the report no earlier than 2012; the 2016 filename-year is adopted as the citation year.
- Author attribution. Institutional author “Malaysian Association of Standards Users” (no individual authors named in the PDF). The corpus convention for institutional authors is to use the organisation name in
authors:as a single-string entry. - DOI. No DOI; NGO grey literature.
doi: nullwithno_doi_assigned: true. - Access URL. Not embedded in the PDF; left null. The report is hosted by Standards Users / FOMCA Malaysia but the URL was not extracted from the PDF metadata at this writing.
- Tier rationale. B-tier per Part 13: NGO grey-literature consumer-testing report using accredited laboratory methods but not peer-reviewed. The published PDF documents the laboratory methods (USEPA 3570 + 8270 C) and analyte panels but redacts the laboratory identities, so the chain-of-custody and QC documentation are not independently verifiable from the PDF alone. Matches B-tier corpus handling of NGO comparative-testing reports.
- Source-type rationale.
source_type: ngo: civil-society comparative-testing publication by a national consumer-standards organisation, with policy-advocacy framing toward the Malaysian Department of Standards and Ministry of Health. - Frontmatter
metals: [Pb, Cd, tAs, Sb, Cr, tHg]. The report does not measure heavy metals in the eight samples. The metals are declared in frontmatter because the report transcribes regulatory limits for them in Tables 1 and 2 (Danish EN 71-3 and Malaysian MS 1156:1989) in the pacifier/soother regulatory context. Arsenic istAs(total) because the source reports it as “Arsenic, As” without speciation in the regulatory tables; EN 71-3 historically used soluble-element extraction without arsenic speciation. Mercury istHg(total) for the same reason. Barium (Ba) and selenium (Se) appear in the Danish Table 1 but are not in the HMI corpus’ metal-page set (nowiki/metals/barium.mdorwiki/metals/selenium.mdat this writing) and are not declared in frontmatter; the body table preserves them for completeness. - Frontmatter
ingredients: []is correct — no food ingredients involved. Pacifiers and sippy cups are infant-contact product categories, not food matrices. - Frontmatter
matrices: []is correct — no food or biological matrices in the routing-vocabulary sense. The samples are silicone, rubber, and plastic infant-contact-product matrices; these are hard-goods consumer-product matrices, not the food/biomonitoring controlled-vocabulary matrices the routing layer fans out on. Matches Nelson 2023 children’s-jewelry convention. - Frontmatter
products: ["[[products/pacifiers-and-sucking-teething-aids]]", "[[products/sippy-cups-toddler-drinkware]]"]. Both product slugs are existing scaffolded HMTc Taxonomy v2.0 pages (Category 9, Rows 4 and 3 respectively). Six of the eight samples are pacifiers/soothers; one sample is a sippy cup; one sample is a 3-in-1 nursing cup. The 3-in-1 nursing cup is routed tosippy-cups-toddler-drinkwareas the closest existing scaffold (sippy-cup-style drinkware components); no separate slug for 3-in-1 nursing cups exists in the taxonomy at this writing, and a single-instance freq-1 occurrence does not warrant a new scaffold. Per the Phase 1 broad-scope rule, the umbrella scaffolds are used rather than creating sub-form slugs. - Frontmatter
jurisdictions: [MY]. The report is a Malaysian consumer organisation publication about Malaysian retail products and Malaysian regulatory gaps. Other jurisdictions (Denmark, US, Australia, Canada, Fiji, New Zealand) appear in Section 2.6 Table 3 as regulatory-landscape context but are not the primary jurisdiction of the testing. - Brand-firewall (Part 12, strict reading locked 2026-05-17). The published PDF has all brand names, manufacturer/distributor names, places of purchase, and laboratory identities redacted (visibly blanked out in Tables 4 and 5 and in Section 4). This wiki page therefore does not contain brand attribution because the source itself does not contain brand attribution. Sample identification on this page uses the report’s product-form descriptors only (“Symmetrical Soother”, “Silicone Baby Pacifiers”, “Baby Soother”, “Silicone Soother”, “Silicone Soother with Cover”, “BPA Free Silicone Pacifier-Orthodontic Nipple”, “Sippy Cup”, “3-in-1 Nursing Cup”), which are product-form descriptors (silicone vs orthodontic; soother vs nursing cup) and not brand names. Per the strict reading, no brand-by-brand ranking would be possible from this PDF even if attempted; the wiki defaults to the product-form descriptor regardless.
- Scientific-method vendor names (Part 12 Exception 2). The PDF redacts the analytical laboratory identities for both phthalates/nitrosamines and BPA. The named USEPA methods (3570, 8270 C) and the named-but-parent-redacted “Centre for Xenobiotics Studies” are preserved as scientific-method identifications, per Exception 2.
- Wiki/HMTc firewall (Part 2). The Implications section reports the regulatory ceilings the source transcribes and notes the gap between Danish EN 71-3 and Malaysian MS 1156:1989. It does not propose HMTc thresholds, does not compare these limits to other literature beyond what the source itself does (Section 2.6 Table 3), and does not soften or strengthen the reported regulatory values. The Implications section’s HMTc audit bullet identifies what the source contributes to threshold work (regulatory-cap inputs for the lowest-applicable-cap test on pacifiers/soothers) without proposing a threshold.
- Speciation flag. Arsenic is
tAs(total) because the source’s regulatory tables report it as “Arsenic, As” without speciation. Mercury istHg(total) for the same reason. EN 71-3 historically applied a soluble-element acid extraction without speciation; the tabulated limits are not iAs- or MeHg-specific. No iAs, MeHg, or Cr-VI claims appear in the source. - Heavy metals NOT measured. The report’s eight-sample testing covers BPA, phthalates, and nitrosamines only. Heavy metals are present only as regulatory context (Tables 1 and 2). The frontmatter metals declaration reflects the metals discussed regulatorily and routes this source to the metal pages as regulatory_context, not as direct_evidence; the routing layer (CLAUDE.md Part 5b) is the canonical assignment of route_kind, not this verification note.
- Regulation references. The source cites Danish EN 71-3 (soothers element-migration), EN 12868 (nitrosamine method), EN 14060 (soothers), DS/EN 1400-3 (chemical requirements for soothers), Malaysian MS 1156:1989 (Specification for Babies’ Pacifiers), MS 1312:1993 (dichloromethane extraction method for volatile nitrosamines), US CPSC nitrosamine rule and ASTM F1313-90(2011), Australian AS 2432-2009 (Baby Dummies), Canadian Hazardous Products (Pacifiers) Regulations, and the Fijian Trade Standards and Quality Control Decree (phthalate plasticizer ban). None of these have dedicated
wiki/regulations/pages in the 2026-05-18 taxonomy snapshot; the page references them by name and citation in the body rather than wikilinking to non-existent regulation slugs. New regulation pages are not created speculatively from this single source. - Folder context. The PDF lives under
_extracted_infantcontact_02_Teethers_Pacifiers/02_Teethers_Pacifiers/in the Kimi corruption-issue raw tree, consistent with the paper’s pacifier and sippy-cup subject matter (the prior sibling at07_2018_2303004.pdfwas a Washington State children’s jewelry follow-up where the folder naming was inconsistent with the content; here the folder name matches the content). - Filename year vs report date. Filename year tag is “2016”. The report body is undated. The report references the Malaysian BPA ban as effective March 2012 and the 2010 CPSC recall; the publication year is therefore 2012 or later. The filename-tag year 2016 is adopted as the citation year in the absence of an explicit publication date in the PDF.
- Authorship redaction. The named laboratories (Laboratory 1 for phthalates/nitrosamines; Laboratory 2 = “Centre for Xenobiotics Studies” for BPA) are redacted in the PDF. The parent institution of the Centre for Xenobiotics Studies appears blanked out in the same line and is not transcribed.
- Near-duplicates. None identified in the corpus at this writing. The Sen et al. PubMed citation in footnote 3 (non-volatile N-nitrosamines in baby bottle nipples) and the Food and Chemical Toxicology 1985 citation in footnote 2 are background literature references, not corpus entries; they are not ingested in this commit.
- Raw integrity. raw_sha256 = 237ff89f151013e986450ee11f9d57ca8cbb8a1ef7f2e0f77edcae96186110f6 verified by
shasum -a 256against the file atraw_path. - Audit subagent (2026-06-01) flagged the analyte-panel counts; verified against Figure 1 (p. 12) — corrected to six phthalate esters (Dimethyl, Diethyl, Di-n-butyl, Butyl benzyl, Bis(2-ethylhexyl), Di-n-octyl) and ten nitrosamine compounds (N-Nitrosomethylethylamine, N-Nitrosodiethylamine, N-Nitrosopyrrolidine, N-Nitrosomorpholine, N-Nitrosodi-n-propylamine, N-Nitrosopiperidine, N-Nitrosodibutylamine, Diphenylamine, Diallate, Methapyrilene). The earlier draft asserted “seven phthalates” and “eleven nitrosamines” in prose, which conflicted with the body tables that already listed 6 and 10 respectively, and with the Figure 1 ANALYSIS RESULTS panel on p. 12.
