Dimethicone PEG 10/15 Crosspolymer
What is Dimethicone PEG 10/15 Crosspolymer?
Dimethicone PEG 10/15 Crosspolymer is a synthetic polymer derived from dimethicone, a type of polydimethylsiloxane silicone, crosslinked with short polyethylene glycol chains (PEG-10/15). This modification creates a gel-like structure with hydrophilic and hydrophobic properties. Primarily used in skincare, makeup, and hair products, it functions by forming a thin, elastic film upon application, which helps adhere active ingredients and resist water or rubbing. As an opacifying agent, it scatters light to reduce transparency, giving lotions and creams a smooth, uniform, milky appearance while stabilizing emulsions. Its crosspolymer network traps water or oils, providing a non-greasy, velvety texture that enhances spreadability and product stability without heavy buildup.
