What it is
Divinyldimethicone/Dimethicone Copolymer is a crosslinked silicone formed from divinyl- and dimethyl-functional siloxanes, usually supplied as part of a silicone emulsion. It leaves a soft, flexible film on the skin that smooths the surface and gives a velvety, conditioned finish. In sunscreens it contributes to a silky application and an even, non-tacky feel.
Safety & warnings
Silicone film formers of this type are generally well tolerated, non-sensitizing, and tend not to clog pores. They sit largely on the skin surface and are valued for a light, smooth feel.
Origin & sourcing
