Polydimethylsiloxane/Polymethysilesquioxane Copolymer
What is Polydimethylsiloxane/Polymethysilesquioxane Copolymer?
Polydimethylsiloxane/Polymethylsilsesquioxane Copolymer is a synthetic organosilicon compound formed by combining polydimethylsiloxane, a linear silicone chain, with polymethylsilsesquioxane, a three-dimensional cage-like silicone structure. This crosspolymer belongs to the silicone family widely used in cosmetics, particularly in makeup foundations, primers, and powders. It functions as a film-forming agent that creates a flexible, breathable barrier on the skin, helping to absorb excess sebum while providing a soft-focus blur to minimize the appearance of pores and fine lines. Its unique hybrid structure delivers a lightweight, non-greasy matte texture, enhancing product spreadability and longevity without compromising skin comfort. Typically incorporated at low levels, it improves sensory feel and wear performance in formulations.
Benefits
