Cetearyl Dimethicone/Vinyl Dimethicone Crosspolymer

Cetearyl Dimethicone/Vinyl Dimethicone Crosspolymer is a synthetic silicone-based ingredient created by cross-linking different dimethicone polymers. It belongs to a class of silicones used widely in skincare and cosmetics for their texture-modifying and protective properties.In formulations, this ingredient functions as an emollient, film-former, and viscosity controller. It helps create a smooth, even texture in creams and serums whilst forming a lightweight barrier on the skin's surface.

This crosspolymer works by depositing a thin, flexible film on the skin's surface. Unlike larger molecular silicones, its cross-linked structure allows it to create a smooth layer that moves with skin without feeling heavy or waxy.As an emollient, it also penetrates slightly into the outer layers of skin, softening and hydrating the stratum corneum whilst the film-forming action helps reduce moisture evaporation.

This ingredient is typically found in concentrations below 1% in finished products, where it contributes to texture and feel without dominating the formula. It works well in combination with other emollients and humectants. Apply products containing this ingredient to clean skin as part of your regular routine; it pairs well with serums, moisturisers and primers.

Silicone polymers including this ingredient are generally well-tolerated and non-irritating. Some individuals concerned about silicone accumulation on skin may prefer silicone-free alternatives, though evidence of problematic buildup in regular skincare use is limited.
