Functions
Emulsifying
Forces oil and water to stay mixed instead of separating into layers. The unsung hero holding your lotion together.
Cleansing
Makes oil and water mix so dirt, makeup, and sunscreen can actually be washed away. The reason your face wash foams.
Skin Conditioning
A catch-all term for ingredients that improve how skin looks and feels — softer, smoother, more supple. The workhorse behind most moisturizers.
Emulsifier
Reduces Inflammation
Wound Healing
Fights Bacteria
Mixes Oil & Water
Traditional Use
A synthetic derivative combining polyethylene glycol with hydrogenated castor oil, developed in the mid-20th century. Created to stabilize and improve the spreadability of castor oil in cosmetic formulations.
