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.
Emulsifier
Mixes Oil & Water
Traditional Use
A plant-derived surfactant made from glycerin and caprylic acid. Used in cosmetics as a gentle emulsifier and cleanser, often preferred in natural skincare due to its lower toxicity profile.
