What Is Acrylates/Steareth-20 Methacrylate Copolymer?
Acrylates/steareth-20 methacrylate copolymer is a synthetic polymer that blends steareth-20 with one or more forms of methacrylic acid. It functions as a thickening agent in skin care and hair care products. Research has found that unlike some other polymers used in cosmetics, acrylates/steareth-20 methacrylate copolymer rinses more easily from skin and hair, making it more desirable for use.
The independent Cosmetic Ingredient Review board has found acrylates/steareth-20 methacrylate copolymer safe as used in cosmetics. Typical concentration range is from 0.75–1%.
