What it is
This ingredient is a copolymer combining acrylate and ethylhexyl acrylate units with dimethicone (silicone) methacrylate. The hybrid structure forms a flexible, cohesive film on the skin that helps hold the formula together and supports even, lasting wear. It is commonly used in sunscreens and color cosmetics where a uniform, durable finish is desired.
Safety & warnings
Acrylate and silicone film-forming copolymers of this type are generally considered low-irritation and non-sensitizing at cosmetic use levels.
Origin & sourcing
Synthetic; a copolymer produced by polymerizing acrylate and silicone-functional methacrylate monomers.
Questions everyone asks
What does this copolymer do in a sunscreen?
It forms a smooth, flexible film that binds the formula together and helps it wear evenly and last on the skin.
Is it a silicone?
It is a hybrid polymer that incorporates silicone (dimethicone) units along with acrylate units, combining properties of both.
