Functions
Skin Conditioning
A catch-all term for ingredients that improve how skin looks and feels — softer, smoother, more supple. The workhorse behind most moisturizers.
Emollient
Fills in the tiny cracks between skin cells to make everything feel smooth and soft. The "silky finish" ingredient.
Film Forming
Creates a physical seal on skin to lock moisture in and keep irritants out. The "slugging" ingredient — barrier protection.
Locks in moisture
Traditional Use
Developed in the late 20th century as a modern silicone emulsifier. Created to improve the texture and spreadability of cosmetic formulations by combining silicone polymers with polyether and benzoate ester chemistry.
