Diphenylsiloxy Phenyl Trimethicone is a phenyl-substituted silicone fluid used in cosmetics as a skin- and hair-conditioning emollient that imparts a smooth, glossy feel and enhanced spreadability. It provides shine, water resistance, and improved sensory texture without significant skin penetration.
