Dimethicone/Divinyldimethicone/Silsesquioxane Crosspolymer

What is Dimethicone/Divinyldimethicone/Silsesquioxane Crosspolymer?

Dimethicone/Divinyldimethicone/Silsesquioxane Crosspolymer is a synthetic silicone crosspolymer formed by linking dimethicone and divinyldimethicone chains with silsesquioxane units through a crosslinking process. This creates a stable, gel-like matrix used primarily in makeup such as foundations, powders, and primers, as well as select skincare products. It functions by forming a flexible network that swells in oils to absorb sebum, delivering a soft-focus blur effect and matte finish. In formulations, it adjusts thickness for better spreadability, reduces clumping in dry products by repelling moisture, and establishes a lightweight barrier to shield against environmental stressors while supporting hydration levels in the skin's outer layer. Its unique structure enhances product stability and sensory appeal without heaviness.
