Ethylene/Acrylic Acid Copolymer

Ethylene/Acrylic Acid Copolymer is a synthetic polymer used as a film former, binder, and emulsion stabilizer, most often in mascara and other wear-resistant makeup. It has not had a dedicated cosmetic safety review, but the same copolymer family has long-standing FDA clearance for direct food-contact use under strict extractable-substance limits, which is consistent with a low-migration, largely inert material at the film-forming molecular weights used in cosmetics.

Cosmetic information for general education, not medical advice. A verdict is a reading of the published evidence, never a guarantee for your skin: any ingredient can irritate someone, so patch test new products and see a professional if you react. Concern is graded on cited evidence, never on hazard-score lists. See how we score.
