Functions

Perfuming

Added for scent. Can be natural or synthetic. Common irritant and allergen — one of the top reasons people react to products.

Emollient

Fills in the tiny cracks between skin cells to make everything feel smooth and soft. The "silky finish" ingredient.

Solvent

Dissolves other ingredients so they distribute evenly in the formula. Often the invisible "base" everything else is mixed into.

Viscosity Controlling

Locks In Moisture

Traditional Use

Derived from oleic acid found in olive oil and other plant oils used for centuries in traditional medicine and skincare. Modern synthetic production began in the early 20th century for use as an emollient and emulsifier in cosmetics.
