Emulsifying
Forces oil and water to stay mixed instead of separating into layers. The unsung hero holding your lotion together.
Surfactant
Makes oil and water mix so dirt, makeup, and sunscreen can actually be washed away. The reason your face wash foams.
Traditional Use
A modern polyethylene glycol derivative of stearic acid developed in the mid-20th century as a thickening and emulsifying agent for cosmetics and creams.
