What it is
This copolymer is a synthetic acrylate-based resin that dries to a flexible, cohesive film. In sunscreens and sprays it helps distribute UV filters evenly and keep the film intact during wear. It is frequently chosen for sprays and lotions where an even, persistent coating supports consistent filter performance.
Safety & warnings
Acrylates/octylacrylamide copolymer is generally well tolerated and used at modest levels as a film former. It is not a recognized fragrance allergen. Spray products containing it should be applied as directed to avoid inhalation of the aerosol.
Origin & sourcing
Synthetic; manufactured by polymerizing acrylate monomers with octylacrylamide.
