PEG-10 Dimethicone/Vinyl Dimethicone Crosspolymer

PEG / Ethoxylated

What is PEG-10 Dimethicone/Vinyl Dimethicone Crosspolymer?

PEG-10 Dimethicone/Vinyl Dimethicone Crosspolymer is a synthetic silicone-based polymer formed by crosslinking dimethicone—a polydimethylsiloxane—with vinyl dimethicone and incorporating short polyethylene glycol (PEG-10) chains for hydrophilicity. Primarily used in water-in-oil or oil-in-water emulsions like creams, lotions, and foundations, it creates a three-dimensional gel network upon hydration. This network traps oils and water phases, preventing emulsion breakdown and phase separation during storage. As a viscosity controller, it thickens products without stickiness, aiding suspension of pigments or actives and improving spreadability on skin for even application and comfortable wear.
