Science
Mechanism of Action
Triolein operates by creating an occlusive layer on the skin's surface, which significantly reduces transepidermal water loss and promotes lasting hydration. Beyond its moisturizing capabilities, it acts as a penetration enhancer, subtly modifying the lipid matrix of the stratum corneum to facilitate the absorption of other active ingredients. Emerging research also suggests it may offer soothing benefits and help mitigate oxidative stress in skin exposed to UVB radiation.

Stability
Triolein is generally stable but susceptible to degradation from air and light, necessitating storage in tightly sealed containers in a dry environment at 2-8℃. Prolonged exposure to air and moisture should be avoided. As a triglyceride ester, it can be hydrolyzed by strong acids and bases, and thermal decomposition may release irritating gases.

Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed triolein safe for use in skincare, noting it is not associated with significant dermal irritation, sensitization, or photosensitization. Ocular exposure typically results in only mild irritation. Triolein has not shown genotoxic effects, and its metabolic pathways are similar to dietary fats, with FDA GRAS status for specific food applications.
