Per- and Polyfluoroalkyl Substances and alternatives in cosmetics: report on commercial availability and current uses
Summary
Researchers reviewed alternatives to per- and polyfluoroalkyl substances (PFAS) in cosmetic products, finding that technically and economically viable substitutes are widely available for functions like conditioning, emulsifying, and water resistance, though replacing PFAS typically requires complete product reformulation rather than simple drop-in swaps.
This report gathers information on alternatives to per- and polyfluoroalkyl substances (PFAS).in cosmetic products, focusing on their commercial availability, current uses, market penetration, feasibility, effectiveness, and cost. PFASs provide a wide range of functions in cosmetic products, acting as hair and skin conditioning agents, emulsifiers, stabilisers, oil and water-resistant agents, lubricants, bulking agents and/or oil-resistant surfactants. Technically and economically feasible alternatives to intentionally used PFASs in cosmetic products are widely available on the market, which implies a high substitution potential. However, substituting PFASs in cosmetics often requires the entire product reformulation to provide the same functionalities to the product, and like-for-like ‘drop-in’ replacements are unlikely to happen.
