Science
Mechanism of Action
As a hydrophobic and non-polar molecule, Tripalmitolein acts as a potent emollient by establishing an occlusive film on the skin's surface. This barrier effectively reduces transepidermal water loss (TEWL), thereby optimizing skin hydration and fortifying the skin's natural barrier function. While direct topical studies on Tripalmitolein are limited, its constituent fatty acid, palmitoleic acid, is recognized for anti-inflammatory effects, accelerated wound healing, and improved hydration, suggesting plausible broader benefits upon potential enzymatic hydrolysis within the skin.

The Formula
Formulation
Stability
Tripalmitolein is a liquid at ambient temperature and is insoluble in water, readily dissolving in organic solvents such as chloroform. Its chemical stability is inherently influenced by the three unsaturated fatty acid chains, which represent sites for potential oxidative degradation. For optimal long-term stability, storage at -20°C is recommended; otherwise, it maintains good stability under typical storage and handling conditions. Hydrogenation reactions can modify its inherent double bonds.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has assessed Tripalmitolein and concluded it is safe for use in cosmetic formulations under current practices and concentrations. It is included in an amended safety assessment encompassing 51 triglycerides and is officially recognized by the FDA with the Unique Ingredient Identifier (UNII) number N9836937KG.
