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
A synthetic polymer emulsifier developed in the late 20th century combining polyethylene glycol and polypropylene glycol with synthetic fatty alcohols. Created to replace traditional soap-based emulsifiers and improve product stability and feel.
