Dimethicone/Phenyl Vinyl Dimethicone Crosspolymer

AKA: Silicone Crosspolymer
Synthetic
Silicone
Clean
OriginDerived from dimethyl siloxane polymers and phenyl vinyl siloxane monomers, both synthesized from silicon and organic precursors. Produced through hydrosilylation cross-linking reactions that bond siloxane chains with vinyl groups, creating a three-dimensional network polymer.
