What Decyl Oleate does

Softens and smooths the skin
Helps formulas spread easily
Adds a silky, non-greasy feel

Decyl Oleate is made by joining oleic acid, a fatty acid found in many plant oils, with decyl alcohol, a fatty alcohol. The result is an ester, a type of molecule that many cosmetic oils are built from. Formulators use it to give a formula a soft, smooth skin feel without a heavy, greasy layer.

Because it is a lighter oil, it spreads quickly and leaves a soft, non-greasy finish. That makes it useful in lotions, creams and makeup, where it helps other ingredients glide over the skin. It is a common choice when a product needs slip but should not feel thick.

Good for

Suits people who like lightweight moisturizers and makeup that glides on without feeling greasy.
