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.
Cleansing
Makes oil and water mix so dirt, makeup, and sunscreen can actually be washed away. The reason your face wash foams.
Locks in moisture
Traditional Use
A modern synthetic surfactant and emulsifier developed in the late 20th century. It was engineered to provide milder cleansing and emulsifying properties compared to stronger surfactants, meeting demands for gentler contemporary cosmetic formulations.
