OLEIC/LINOLEIC TRIGLYCERIDE.

Valuable / SKIN CONDITIONING - EMOLLIENT

Oleic/Linoleic Triglyceride is a versatile skin conditioning agent and emollient, expertly formulated to soften and smooth the skin. It effectively supports the skin's natural barrier function, replenishes essential lipids, and delivers deep hydration.

Science

Mechanism of Action

This ingredient functions as an emollient by forming a protective lipid barrier on the skin's surface, significantly reducing transepidermal water loss (TEWL) and locking in essential moisture. Its composition, rich in linoleic acid, is crucial for ceramide synthesis, which in turn maintains the structural integrity and permeability of the stratum corneum, fortifying the skin's barrier. The oleic acid component provides profound hydration and can also act as a penetration enhancer for other actives. Furthermore, it possesses cleansing properties, aiding in the dissolution of dirt and oils, and serves as an emulsion stabilizer and viscosity-controlling agent in cosmetic formulations.

Stability

As a triglyceride, it is generally stable. However, the linoleic acid component, due to its high unsaturation, can be susceptible to oxidation; thus, antioxidants like Vitamin E are recommended to enhance stability. A high oleic acid content contributes to robust stability against oxidation and photo-oxidation.

Safe as used
Sensitization risk Low

The Cosmetic Ingredient Review (CIR) Expert Panel concluded that Oleic/Linoleic Triglyceride, among 51 other triglycerides, is safe for use in cosmetic products under current practices and concentrations. Formulations containing these ingredients were reported to be non-irritating and non-sensitizing to human skin, although formulators are advised to consider their potential for penetration enhancement. The Environmental Working Group (EWG) also rates related polyglycerides as safe for cosmetic applications.
