Functions
Cleansing
Makes oil and water mix so dirt, makeup, and sunscreen can actually be washed away. The reason your face wash foams.
Emollient
Fills in the tiny cracks between skin cells to make everything feel smooth and soft. The "silky finish" ingredient.
Skin Conditioning
A catch-all term for ingredients that improve how skin looks and feels — softer, smoother, more supple. The workhorse behind most moisturizers.
Cleansing Surfactant
Removes Impurities
Traditional Use
Developed as a synthetic emulsifier combining polyglycerin with caprylic acid. Used in cosmetics for light-texture emulsification and conditioning.
