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.
Traditional Use
Developed in the mid-20th century as a nonionic surfactant and emulsifier. Used in cosmetics and personal care products for its ability to solubilize oils and improve product texture, with no traditional or historical use prior to synthetic polymer development.
