Functions
Emollient
Fills in the tiny cracks between skin cells to make everything feel smooth and soft. The "silky finish" ingredient.
Skin Conditioning
A catch-all term for ingredients that improve how skin looks and feels — softer, smoother, more supple. The workhorse behind most moisturizers.
Emulsifying
Forces oil and water to stay mixed instead of separating into layers. The unsung hero holding your lotion together.
Emulsifier
Mixes Oil & Water
Traditional Use
A synthetic emollient ester created from octyldecyl alcohol and oleic acid. Used in cosmetics as a conditioning and softening agent for both skin and hair care products.
