Divinyldimethicone/Dimethicone Crosspolymer

What is Divinyldimethicone/Dimethicone Crosspolymer?

Divinyldimethicone/Dimethicone Crosspolymer is a synthetic silicone-based polymer created by crosslinking dimethicone chains with divinyldimethicone units, resulting in a gel-like network structure. It appears in makeup primers, foundations, sunscreens, and moisturizers within the cosmetics category. This ingredient functions by forming a thin, elastic film on the skin that boosts water repellency, wear time, and shine while allowing breathability. As a skin conditioner, it deposits a smooth layer to enhance softness and flexibility without greasiness. In formulations, it acts as a viscosity controller, stabilizing emulsions and improving texture for better spreadability and suspension of other components. Its inert nature ensures compatibility across product types, providing a lightweight, velvety finish prized in performance-driven skincare and color cosmetics.
