Modddaresi and Yu 2022 - cosmetics heavy-metal limits and analytical tests

Modddaresi and Yu review cosmetic heavy-metal impurity controls across the EU/UK, United States, Canada, China, India, and German BVL technical guidance. The paper does not report new finished-product measurements; its useful content is regulatory context and method comparison for Pb, As, Cd, Hg, Sb, and related trace metals. This page is therefore context-only and should not be routed into product occurrence pools.

Key numbers

• Source identity: IFSCC 2022 full paper by Personal Care Regulatory Ltd, Cambridge, UK; no DOI printed in extracted text.
• Scope: comparative review of major cosmetic markets and whether heavy-metal contamination in finished cosmetic products is limited through self-regulatory notification systems, mandatory notification, or obligatory registration.
• EU Cosmetic Regulation EC 1223/2009 rows in Table 1: Pb prohibited in Annex II/289; As prohibited in Annex II/43; Cd prohibited in Annex II/68; Hg prohibited in Annex II/221; Sb prohibited in Annex II/40.
• EU REACH rows in Table 1: Pb controlled under Annex XVII entry 63; As under entry 19; Cd under entry 23; Hg under entry 18; antimony not controlled as antimony on its own.
• German BVL technically unavoidable limits in Table 1: Pb 2.0 mg/kg in general products and 0.5 mg/kg in toothpaste; As 0.5 mg/kg in general products and toothpaste; Cd 0.1 mg/kg in general products and toothpaste; Hg 0.1 mg/kg in general products and toothpaste; Sb 0.5 mg/kg in general products and toothpaste.
• Canada Cosmetic Ingredient Hotlist row: Pb, As, Cd, Hg, and Sb are listed as prohibited.
• US FDA rows in Table 1: Pb maximum 10 mg/kg as an impurity in cosmetics and 20 mg/kg in colour additives; As not more than 3 mg/kg in colour additives; Hg allowed only as preservatives in eye-area products, must not exceed 65 ppm in the finished product when no other effective safe preservative is available, and not more than 1 mg/kg in colour additives.
• China Safety & Technical Standard 2015 rows in Table 1: Pb must not exceed 10 mg/kg in finished product; As 2 mg/kg; Cd 5 mg/kg; Hg 1 mg/kg.
• India Cosmetic Rules 2020 rows in Table 1: permitted synthetic organic colours and natural organic colours used in cosmetics must not contain more than 2 mg/kg Pb calculated as lead or more than 2 mg/kg As calculated as arsenic trioxide; use of lead compounds and arsenic compounds for colouring cosmetics is prohibited; eye-area preservatives may contain mercury up to 70 mg/kg calculated as metal, while unintentional mercury in other finished cosmetic products must not exceed 1 mg/kg.
• Analytical methods: China Safety & Technical Standard 2015 specifies hydride generation atomic fluorescence spectrometry for mercury and arsenic, graphite furnace atomic absorption spectrometry for lead, and flame atomic absorption spectrophotometry for cadmium.
• FDA method context: the review describes an FDA-validated total-dissolution method using hydrofluoric acid; arsenic, cadmium, chromium, cobalt, lead, and nickel were analysed by ICP-MS and mercury by cold vapor atomic fluorescence spectrometry in the cited FDA market survey.
• ISO context: ISO/TR 17276:2014 gave general screening and measurement guidance for heavy metals in cosmetic raw materials and finished products, while ISO 21392:2021 details ICP-MS and is described as detecting trace metals down to 0.02 mg/kg.
• Discussion examples: the review states that arsenic acceptable levels differ across jurisdictions, using 2 ppm in the United States, 3 ppm in China, and 0.5 ppm in Germany as examples; it also states that US and China lead limits of 10 ppm are five times the German value.

Methods (brief)

This is a narrative/comparative review, not a laboratory study. The authors selected representative regulatory systems: the United Kingdom, Canada, European Union, and United States for self-regulatory or notification systems, and China and India for obligatory registration systems. They reviewed cosmetic regulations, horizontal chemical regulations, heavy-metal impurity limits, and analytical-test guidance relevant to finished cosmetic products and raw materials.

No primary samples were collected, no extraction/digestion experiment was performed by this source, and no product-level concentration table is reported. The analytical methods described are cited regulatory/standard methods rather than methods applied by the authors to new samples.

Speciation: arsenic and mercury limits are mostly presented as elemental/regulatory totals unless a regulation specifies a compound calculation basis, such as India calculating arsenic as arsenic trioxide. This page does not infer inorganic arsenic or methylmercury occurrence values from those regulatory rows.

Implications

Certification (HMTc): This source is regulatory crosswalk context for cosmetic heavy-metal impurity limits and analytical methods. It is not finished-product occurrence evidence and should not contribute concentration values to product benchmark pools.

Courses: The review is useful for teaching how cosmetic-heavy-metal controls differ between prohibition-based systems, technically unavoidable guidance values, colour-additive impurity limits, and mandatory finished-product limits.

App: If a regulatory comparison view is added for adult cosmetic/personal-care products, this source can support a compact crosswalk of EU/UK, US, Canada, China, India, and German BVL approaches. It should not be surfaced as a product contamination survey.

Verification notes

• PDF text was extracted with pdftotext -layout to /tmp/mfk_june8_ifscc_2022_cosmetics_metals.txt. The title/byline, abstract, heavy-metal subsections, Table 1, analytical-method section, discussion, conclusion, and references were checked against this page.
• No DOI is printed in the extracted text. Title text, raw handle MFK_heavy-metal-content-in-cosmetic-products-ifscc, raw SHA-256 d38127492edcc109290586735c04abc17e0799ee84d15242b26a1661fc77b56e, and candidate cite-key modddaresi2022-cosmetics-heavy-metal-limits were searched before creation; no existing source page was found.
• Units are copied exactly as the source prints them (mg/kg, ppm, and the source’s regulatory calculation bases). No conversion was performed.
• Speciation: the paper discusses regulatory limits and prohibitions, not new chemical speciation measurements. This page records As and Hg as total-context regulatory rows and does not treat them as iAs or MeHg.
• Evidence tier: C because the paper is a useful review/crosswalk but not an official regulation, agency report, or primary occurrence dataset.
• Routing: products is intentionally left empty because the source is a context-only regulatory/method review covering cosmetics generally; no specific product category has occurrence measurements in this source. No product or ingredient slug was invented.
