C4-24 Alkyl Dimethicone/Divinyldimethicone Crosspolymer

What is C4-24 Alkyl Dimethicone/Divinyldimethicone Crosspolymer?

C4-24 Alkyl Dimethicone/Divinyldimethicone Crosspolymer is a synthetic silicone-based polymer formed by cross-linking dimethicone with long-chain C4-24 alkyl groups and divinyldimethicone. This creates a soft, elastic gel network typically used in skincare and color cosmetics like foundations, powders, and primers. It acts as a film former and viscosity controller, enabling easy spreadability and a lightweight feel on skin. The alkyl chains enhance compatibility with oils while the crosspolymer structure traps sebum, delivering a blurred, velvety matte effect without heaviness. Commonly incorporated into oil-absorbing formulations, it supports stable textures and comfortable, non-sticky wear throughout the day.
