PFAS in Cosmetics: How to Identify Hidden Ingredients & Risks

As global scrutiny of cosmetic ingredients grows, per- and polyfluoroalkyl substances (PFAS) are emerging as a major concern for both regulators and consumers. Widely valued for their durability, water resistance, and long-lasting performance, PFAS have been used in a variety of beauty and personal care products. However, their persistence in the environment and potential health risks are driving increased attention worldwide.

Identifying Potential PFAS in Cosmetics

Ingredient Names Containing “Perfluoro” or “Polyfluoro”

One of the clearest indicators of PFAS in cosmetics is the ingredient label. Ingredients that include prefixes such as “perfluoro” or “polyfluoro” may suggest the presence of PFAS compounds. These substances are commonly incorporated into formulations to improve texture, spreadability, adhesion, and wear time.

In the United States, the U.S. Food and Drug Administration (FDA) monitors PFAS usage in cosmetics and publishes related findings, although it does not currently require consumers to follow specific screening methods. Meanwhile, Taiwan has taken a stricter regulatory approach by prohibiting 13 PFAS ingredients in cosmetics, including PFOS and its salts, APFO, PFOA, PFDA and its salts, and PFNA and its salts.

Claims of Waterproof or Long-Lasting Performance

Marketing claims such as “waterproof,” “transfer-proof,” or “long-wear” can also serve as useful indicators for consumers and brands to examine formulations more closely. While these claims do not automatically confirm the presence of PFAS, such chemicals are often used to enhance durability, resistance, and product adhesion—particularly in mascaras, foundations, eyeliners, and lip products.

One PFAS ingredient, Perfluorohexylethyl Triethoxysilane, has already been identified by the FDA as a potential safety concern when used at maximum concentrations in body lotions.

PFAS Usage Trends in Cosmetics

According to FDA findings, polytetrafluoroethylene (PTFE) is currently the most commonly used PFAS ingredient in cosmetic products in the United States. PTFE appears in approximately 490 cosmetic products, representing 28.1% of all PFAS-containing cosmetic formulations. Several other PFAS-related ingredients also appear frequently across product categories.

Why PFAS Awareness Matters

For cosmetic brands, these indicators represent more than consumer guidance—they highlight the growing need for robust formulation reviews, supplier verification, and stronger regulatory compliance practices. As global PFAS regulations continue to evolve, proactively identifying and addressing potential PFAS risks can help companies reduce compliance challenges, strengthen consumer trust, and future-proof their product portfolios.

For consumers, ingredient awareness and label transparency remain essential tools in making informed purchasing decisions. Choosing brands that prioritize safety, transparency, and regulatory responsibility can contribute to healthier and more sustainable beauty choices.
