What it is
Acrylates/diacetoneacrylamide copolymer is a synthetic copolymer designed to deposit a continuous, flexible film as a product dries. This film helps distribute and hold other ingredients evenly across the skin and improves the durability and uniformity of the applied layer. It is frequently used in sunscreen mists and sprays to support an even, cohesive coating.
Safety & warnings
Film-forming acrylate copolymers are large molecules that remain on the skin surface and are generally well tolerated with low irritation potential. This ingredient is not a recognized fragrance allergen and is not a comedogenic oil.
Origin & sourcing
Synthetic; produced by copolymerizing acrylate monomers with diacetoneacrylamide.
Questions everyone asks

Does it offer any sun protection?
No. It is a film former that supports the formula; sun protection comes from the UV filters in the product.
