PEG-12 Dimethicone
What is PEG-12 Dimethicone?
PEG-12 Dimethicone is a modified silicone polymer derived from dimethicone, a polydimethylsiloxane backbone, etherified with 12 units of polyethylene glycol to enhance water solubility. Commonly found in shampoos, conditioners, and leave-in hair treatments, as well as skin moisturizers and serums, it functions as an emollient and conditioning agent. In formulations, it spreads easily to create a lightweight, non-greasy film on hair shafts and skin surfaces, reducing friction for better manageability and improving product texture for even application. This dual solubility allows it to emulsify oils in water-based products, aiding stability while delivering conditioning benefits without heaviness.
