Dimethicone Copolyol Bon Silicone Hydratation Dimethicone Copolyol description Dimethicone copolyol is a type of silicone, a substance derived from silica (sand is a silica). The unique fluid properties of silicone give it a great deal of slip, and in its various forms it can feel like silk on skin, impart emollience, and be a water-binding agent that holds up well, even when skin becomes wet. The research about silicones have proven them to be superior scar-healing ingredients, soothing agents, non-irritating, and uniquely effective delivery and suspending agents for a wide range of cosmetic ingredients.
