Dimethicone/Phenyl Vinyl Dimethicone Crosspolymer
Dimethicone/Phenyl Vinyl Dimethicone Crosspolymer is a silicone-based crosspolymer with the CAS number 243137-51-1. Chemically, it is described as siloxanes and silicones, dimethyl, polymers with [(dimethylphenylsilyl)oxy]- and [(ethenyldimethylsilyl)oxy]-terminated dimethyl siloxanes. It is formed by crosslinking dimethicone with phenyl vinyl dimethicone, resulting in a three-dimensional polymer network. It is used primarily as a viscosity-controlling agent in cosmetic formulations.
Its primary established function is viscosity control, helping to adjust and stabilize the texture and consistency of cosmetic products. It appears across a wide range of product types including foundations, eye creams, sunscreens, and moisturizers, suggesting broad formulation utility.
