Functions
Emollient
Fills in the tiny cracks between skin cells to make everything feel smooth and soft. The "silky finish" ingredient.
Cleansing
Makes oil and water mix so dirt, makeup, and sunscreen can actually be washed away. The reason your face wash foams.
Emulsifying
Forces oil and water to stay mixed instead of separating into layers. The unsung hero holding your lotion together.
Locks In Moisture
Traditional Use
Synthetic emulsifier created by chemically modifying olive oil with polyethylene glycol. Developed in the mid-to-late 20th century to create a surfactant that combines olive oil's benefits with improved water solubility.
