PEG-14 Dimethicone
What is PEG-14 Dimethicone?
PEG-14 Dimethicone is a silicone polymer created by grafting polyethylene glycol (PEG) chains, specifically 14 units, onto dimethicone, which is polydimethylsiloxane. This chemical modification enhances its solubility in water, distinguishing it from oil-soluble silicones. It appears in hair care items like conditioners and shampoos, as well as skin products such as lotions and serums. Functionally, it spreads evenly to form a thin, breathable layer on surfaces, minimizing friction between strands or skin cells. This action aids in detangling hair, boosting combability, and imparting a silky texture. On skin, it supports a soft, supple feel by locking in moisture lightly without occlusion. Its surfactant-emulsifying traits help mix ingredients in emulsions, ensuring stable, uniform product textures. Overall, it delivers conditioning effects suited to rinse-off and leave-on formulas.
