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
A synthetic compound developed in the 20th century combining silicone with hydroxystearic acid (derived from plant oils). Created to improve emulsification and conditioning in modern cosmetic formulations.
