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.
