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
Developed in the mid-20th century as a synthetic surfactant and emulsifier. Created to balance hydrophilic and lipophilic properties in cosmetic formulations for improved texture.
