PEG/PPG-20/20 Phenylisopropyl Caprylyl Dimethicone
What is PEG/PPG-20/20 Phenylisopropyl Caprylyl Dimethicone?
PEG/PPG-20/20 Phenylisopropyl Caprylyl Dimethicone is a synthetic silicone-based copolymer featuring a dimethicone backbone modified with polyethylene glycol (PEG-20), polypropylene glycol (PPG-20), phenylisopropyl, and caprylyl side chains. This structure combines hydrophobic silicone properties with hydrophilic polyether chains, making it an effective surfactant-emulsifying agent. Primarily used in color cosmetics like foundations and primers, as well as sunscreens and hair care products, it stabilizes water-in-silicone emulsions. It functions by reducing surface tension, enabling uniform blending of oil and water phases, while providing skin conditioning through a lightweight, breathable film. This enhances product spreadability, imparts a silky, non-greasy feel, and supports matte or velvety finishes without residue. Derived from siloxane polymers and alkoxylation processes, it fits into emollient and stabilizer categories in formulations.
Benefits
Delivers smooth, even application in makeup and sunscreens.
Supports stable emulsions for consistent product texture.
Provides lightweight conditioning with a non-greasy finish.
