Carbopol® Ultrez 21 polymer

INCI Name: Acrylates/C10-30 Alkyl Acrylate Crosspolymer

Carbopol® Ultrez 21 polymer is a white powder, crosslinked copolymer of polyacrylic acid that is polymerized in a toxicologically-preferred cosolvent system. Its self-wetting properties makes it extremely easy to use for efficient processing. It is an extremely efficient rheology modifier capable of providing high viscosity and forms sparkling clear gels or hydro-alcoholic gels and creams. Its short flow, non-drip properties are ideal for applications such as clear gels, hydroalcholic gels, creams, and lotions.
