Functions
Film Forming
Creates a physical seal on skin to lock moisture in and keep irritants out. The "slugging" ingredient — barrier protection.
Skin Conditioning
A catch-all term for ingredients that improve how skin looks and feels — softer, smoother, more supple. The workhorse behind most moisturizers.
Viscosity Controlling
Creates Protective Barrier
Traditional Use
A hybrid silicone-silica polymer developed in the late 20th century for cosmetics to create lighter textures with improved absorbency and a more natural feel on skin than conventional silicone polymers.
