As scrutiny around cosmetic ingredients intensifies, per- and polyfluoroalkyl substances (PFAS) have become a focal point for both regulators and consumers. Known for their durability and resistance properties, these chemicals are used in beauty formulations, but their persistence in the environment and potential health risks are raising concerns. For brands and consumers alike, identifying potential indicators of PFAS presence is critical.
Complex Ingredient Names with “Polyfluoro” or “Perfluoro” Prefixes
One of the most direct indicators lies in the ingredient list. Ingredients containing “per/polyfluoro” often signal the presence of PFAS. These ingredients are typically used to enhance texture, spreadability, or wear time. In the US, the FDA monitors PFAS presence and publishes findings, but does not mandate specific ingredient-screening methods for consumers. Similarly, in Taiwan, 13 PFAS ingredients are not allowed to be used in Cosmetics. The 13 PFAS ingredients include: PFOS and its salts, APFO, PFOA, PFDA and its salts, and PFNA and its salts.
Performance Claims of Extreme Durability or Water Resistance
Products marketed as “transfer-proof” or “waterproof” may sometimes use PFAS to help deliver these effects. While such performance claims do not automatically mean a cosmetic contains PFAS, they can be a useful signal to review the ingredient label more carefully. PFAS are often used to enhance product adhesion, durability, and resistance, particularly in mascaras, foundations, and lip products.
One of the PFAS ingredients, Perfluorohexylethyl triethoxysilane, has already been flagged by the US FDA for a potential safety concern at maximum use levels in body lotions.
Based on the FDA’s data, polytetrafluoroethylene (PTFE) is the most frequently used PFAS in cosmetic products in the U.S., appearing in 490 products and accounting for 28.1% of all PFAS-containing cosmetic products, followed by some recurring ingredients.
For cosmetic brands, these potential indicators are more than consumer guidance. They highlight areas where formulation review, supplier verification, and Regulatory compliance must be strengthened. As global regulations tighten, proactively identifying PFAS can reduce risk and enhance brand credibility.
For consumers, awareness is a powerful tool. Reading labels carefully and choosing brands that prioritize transparency can make a meaningful difference.
Stay ahead of PFAS risks with expert guidance from Freyr. With the right Regulatory strategy, brands can detect hidden risks early, ensure compliance, and build safer, future-ready cosmetic portfolios.
