Testing Heavy Metals in Cosmetics and Elemental Analysis
Testing heavy metals in makeup or elemental impurities in cosmetics, including testing to ISO 21392: 2021. Determination of trace levels of potentially toxic metals in raw materials or products, helping you to produce safe and regulatory compliant products
Heavy metals in cosmetics pose potential health risks to consumers. Arsenic, cadmium, chromium, cobalt, lead, mercury, and nickel are elements that are commonly referred to as "heavy metals" or "toxic metals." They can be toxic to humans and this depends on how we are exposed to them, at what levels, for how long and how frequently this occurs. There is an expectation that dermal exposure is typically the most common route as many product types are applied to the skin. Some consumers can develop sensitivity towards these elements potentially leading to allergic contact dermatitis or other skin problems. There is also potential for oral exposure for products such as lipsticks and those used in and around the mouth as these can be ingested or absorbed. Consequently, it is important to understand the levels of heavy metals and have a good understanding of the levels of exposure and the toxicological risk they pose. To ensure consumer safety and reduce health risks from toxic elemental impurities in cosmetics, it is critical to conduct an accurate and sensitive analyses of raw materials or finished cosmetics products.
Regulatory Drivers for Metals Testing in Cosmetics
Multiple countries or regions around the world have established legislation restricting heavy metals in makeup, beauty or personal care products. In Europe, for example, Annex II of Regulation (EC) 1223 / 2009 prohibits the use of heavy metals or heavy metals compounds containing lead, cadmium, arsenic, antimony and mercury in cosmetics except for some mercury compounds which are permitted to be used as preservatives. (Annex V). Article 17 of the regulation permits prohibited substances to be present in cosmetic products at trace levels if their presence is technically unavoidable in good manufacturing practice.
Our Cosmetics Heavy Metals Testing Expertise
Our centre of excellence for cosmetics testing, LaCoMed, which is located near Chalon-sur-Saône in France is a COFRAC accredited laboratory. The LaCoMed laboratory provides high-performance and rapid solutions for trace heavy metals testing and elemental impurities analysis in all types of matrices, raw materials or finished cosmetic products. Supporting your raw materials qualification programs, research and development and production quality control we can provide technical advice and testing services including:
- Heavy metal testing according to ISO standard ISO 21392: 2021 for measurement of chromium, cobalt, nickel, cadmium, lead, antimony or arsenic in cosmetics using ICP/MS techniques.
- Determination of heavy metals in cosmetics including arsenic, cadmium, mercury, lead, and antimony according to the COFRAC accredited internal method. Accreditation n ° 1-2411. Scope available on www.cofrac.fr

- Screening and comparative elemental analysis
- Determination of more than 60 trace metal elements, such as arsenic (As), lead (Pb), cadmium (Cd), mercury (Hg), nickel (Ni), chromium (Cr), antimony (Sb) and more
Toxicological Risk Assessments
Our toxicology consultants are experienced in delivering advisory services related to metals in cosmetics product quality, safety, efficacy and labelling requirements. We evaluate the toxicity of the individual chemical ingredients of the formulation used to manufacture the product where each ingredient is assessed for its hazard or "inherent" toxicity such as acute toxicity, skin/eye irritancy, potential for skin sensitization, reproductive, genotoxic, or carcinogenic activity, in relation to the potential for consumer exposure to the chemical. We can also evaluate the potential for synergistic or unpredictable adverse effects from the combination of ingredients in the formulation and assess exposure considerations such as the characteristics of the product such as physical form and size/volume, accessibility (e.g. liquid components) and intended use.
