C20-24 Alkyl Dimethicone
What is C20-24 Alkyl Dimethicone?
C20-24 Alkyl Dimethicone is a synthetic organosilicon compound, consisting of a polydimethylsiloxane backbone grafted with long C20-24 alkyl chains. This structural modification boosts its oil solubility and emolliency compared to standard dimethicone. Commonly found in skincare items like moisturizers, sunscreens, and primers, it functions by creating a thin, flexible film on the skin surface. This film delivers a velvety slip and sheen while helping to minimize transepidermal water loss without greasiness. As a viscosity modifier, it influences flow properties, aiding even distribution of pigments or actives and preventing phase separation in emulsions. Its large molecular weight limits absorption, keeping action topical for enhanced sensory appeal in daily cosmetics.
