Heavy Metals & Contaminant Testing for Cosmetics
Trace Metals, Impurities & Substances of Concern in Beauty Products
Cosmetic products can contain trace substances originating from raw materials, pigments, minerals, manufacturing processes, packaging or environmental sources. Measuring these substances can support product development, supplier qualification, quality investigations and risk-based technical evaluation.
Materials Metric provides heavy metal and contaminant testing for cosmetics, makeup, skincare products, pigments and personal care formulations using analytical techniques selected for the target analytes, expected concentration range and sample matrix.
Heavy Metals Testing
Testing scopes may include the following elements, with additional analytes added when relevant to a specific product or market:
- Lead
- Arsenic
- Cadmium
- Mercury
- Chromium
- Nickel
- Cobalt
- Other trace or bulk elements based on project requirements
Analytical Techniques
ICP-MS
Highly sensitive multi-element analysis suitable for trace-level quantification when low detection limits are required.
ICP-OES
Quantitative elemental analysis across a broad concentration range for many product and raw-material matrices.
XRF
Rapid elemental screening and characterization for certain powders, pigments, minerals and other solid cosmetic materials.
Additional Cosmetic Contaminant Testing
Depending on formulation, raw materials, manufacturing history and target market, customized analytical programs may investigate substances such as:
- PFAS
- Formaldehyde or formaldehyde-related analytes
- 1,4-Dioxane
- Phthalates
- Residual solvents
- Selected allergens
- Process impurities
- Other formulation-specific contaminants
Products Commonly Tested
- Lipstick and lip products
- Eye shadow and eyeliner
- Foundation and concealer
- Face powder and blush
- Cosmetic pigments
- Mineral cosmetics
- Skincare products
- Creams and lotions
- Raw ingredients
- Botanical or mineral raw materials

Frequently Asked Questions
How do you test cosmetics for heavy metals?
Cosmetic samples are prepared using a method appropriate for the matrix and analyzed using elemental techniques such as ICP-MS or ICP-OES. The method should be selected based on the target elements, expected concentration range and required detection limits.
Can makeup contain trace metals?
Trace metals can occur naturally in mineral and pigment raw materials or enter products through other sources. Laboratory analysis determines whether specific elements are present and quantifies their concentration.
Can raw cosmetic pigments be tested before formulation?
Yes. Pigments, mineral powders, fillers and other raw materials can be evaluated independently before they are incorporated into a finished cosmetic product.
Can you test cosmetics for PFAS or other contaminants?
Potentially, yes. The appropriate method depends on the specific contaminant, product matrix and required reporting level. A customized analytical scope should be established before testing.
What is ICP-MS testing for cosmetics?
ICP-MS is a sensitive elemental-analysis technique commonly used to quantify trace metals in complex samples. It can measure multiple elements in one analytical program when suitable preparation and quality controls are used.
