Dimethicone Crosspolymer Bon Silicone No known benefits Dimethicone Crosspolymer at a glance A derivative of the silicone dimethicone Used as a stabilizer, suspending agent, and thickener Considered safe as used in cosmetics Is non-occlusive, meaning it does not “suffocate” skin Dimethicone Crosspolymer description Dimethicone crosspolymer is a silicone derivative used as a stabilising and suspending agent or as a thickener in skin care products, almost always with pure dimethicone or another type of silicone. In its raw form, dimethicone crosspolymer is a gel. The independent Cosmetic Ingredient Review panel has found dimethicone crosspolymer safe as used in cosmetics, and found that because of its larger molecule size, it does not penetrate skin. In leave-on products, it is used in amounts up to 25%. In recent years, silicone and its derivatives have been scrutinises amid claims that they “suffocate” skin, leading to clogged pores and increased blemish breakouts, yet research hasn’t substantially proven that. In fact – again because of molecular size and configuration– silicones allow other ingredients to go past skin’s surface, yet they remain on top. Because of their porous nature, silicones are also light and non-occlusive, meaning they provide moisturising properties without feeling thick or heavy. Related ingredients: Silicone Dimethicone
