WHAT'S IT DO?
Functions
Cleansing
Makes oil and water mix so dirt, makeup, and sunscreen can actually be washed away. The reason your face wash foams.
Antimicrobial
Keeps your product from growing bacteria, mold, or yeast. Without these, that jar of cream becomes a petri dish in about a week.
Fights Bacteria
Traditional Use
A synthetic non-ionic surfactant developed in the mid-20th century. Functions as an emulsifier and solubilizer in cosmetic formulations.
