Why do you use dimethicone?

Dimethicone is a linear silicone that we use primarily to enhance the texture and spreadability of our liquid color cosmetics on the skin. Rigorous scientific analyses have shown no evidence of toxicity to humans, as it is a large molecule that sits on the skin or hair (rather than being absorbed). After reviewing a comprehensive toxicological review of the ingredient (which Beautycounter commissioned before we decided whether we’d use this ingredient), we believe it is safe for use in cosmetics. Linear silicones are completely different from cyclic silicones, known as cyclosiloxanes, some of which have been shown to be possibly carcinogenic, exhibit hormone activity, and be environmentally persistent. These cyclosiloxanes are on The Never List™.
