Surfactant

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.

Emulsifier

Forces oil and water to stay mixed instead of separating into layers. The unsung hero holding your lotion together.
