Divinyldimethicone
What is Divinyldimethicone?
Divinyldimethicone is a silicone polymer featuring vinyl groups attached to a polydimethylsiloxane backbone, commonly used as a cross-linking agent in silicone elastomers for skincare formulations. It imparts a smooth, silky texture to products and enhances the delivery of other active ingredients by forming stable, breathable films on the skin. In products like primers and gels, it contributes to a non-greasy, matte finish while improving product spreadability and longevity.
