Makes oil and water mix so dirt, makeup, and sunscreen can actually be washed away. The reason your face wash foams.
Locks in moisture
Traditional Use
Synthetic ester developed in the mid-20th century as an emollient and skin conditioning agent. Functions as a lightweight moisturizer and texture enhancer in cosmetic formulations.
