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.
Removes Impurities
Traditional Use
A synthetic emulsifier developed in the mid-20th century combining polyethylene glycol with isostearic acid (a branched form of stearic acid). Created to provide stable, mild emulsification for modern cosmetic and personal care formulations.
