Bis-PEG-15 Dimethicone/IPDI Copolymer is a silicone-polyurethane copolymer used in cosmetic formulations as a film-forming agent and emulsifier, helping improve spreadability, water resistance, and a smooth skin feel. It is considered a base/formulation ingredient rather than an active treatment compound.
