About this ingredient
Acrylates Copolymer is a synthetic film-forming polymer made by copolymerizing acrylic and methacrylic acids. Used in cosmetics in aqueous and aqueous-silicone systems for water and sweat resistance. Mechanism. After solvent evaporation the copolymer forms a thin hydrophobic film on the skin. The film is elastic and gas-permeable, locking UV filters and pigments in place against water and sweat. Functions as a fixative and water-resistant base. Where applied. Water-resistant sunscreens (0.5–3%), foundations, primers, hair sprays, water-resistant makeup. Standard in SPF 30+ sunscreens by Bioderma Photoderm, La Roche-Posay Anthelios, Isdin Fotoprotector, Heliocare. Safety. CIR confirmed safety in 2002 at cosmetic concentrations. The molecule is too large to penetrate the epidermis, so no systemic action. Hypoallergenic, non-comedogenic, non-irritating. Pregnancy and lactation – safe. Acceptable at any stage; acrylates-copolymer sunscreens are an optimal choice for gestational melasma. Environmental controversy. Acrylates Copolymer is synthetic, water-insoluble, and not readily biodegradable. It reaches wastewater and the sea after rinse-off. Europe expanded microplastic restrictions from 2023 (EU Regulation 2023/2055). Brands are gradually switching to biodegradable alternatives (silica, biodegradable polymers). Functional role. No standalone skin benefit.
