What Is Vinyl Dimethicone/Methicone Silsesquioxane Crosspolymer?

Vinyl dimethicone/methicone silsesquioxane crosspolymer is a synthetic blend of silicone polymers that functions as a thickening agent and texture enhancer. It’s considered a silicone elastomer since it can significantly improve glide as you apply skin care products formulated with this ingredient. It lends a beautiful, powder-smooth finish to cosmetics.

It is typically used in amounts between 0.1–20%, with amounts up to 0.6% common in rinse-off products. The independent Cosmetic Ingredient Review panel has deemed vinyl dimethicone/methicone silsesquioxane crosspolymer safe as used in cosmetics.
