Science
Mechanism of Action
Derived from sesame seed oil, this ethyl ester variant incorporates key components such as linoleic and oleic fatty acids, Vitamin E, and lignans like sesamin and sesamolin. These constituents are recognized for their antioxidant, anti-inflammatory, and moisturizing properties. Functionally, it primarily acts as an emollient, promoting skin softness, and a skin conditioning agent, improving overall texture. The esterification process also confers high oxidative stability, prolonging product integrity, and can enhance the solubility of other active cosmetic ingredients within formulations.

Stability
Fatty acid ethyl esters, including those derived from sesame oil, exhibit high oxidative stability. The natural antioxidants (lignans, tocopherols) inherited from sesame seed oil further contribute to its resistance against oxidation. While a pH of 7.0 is noted for purification in non-cosmetic contexts, optimal pH for cosmetic formulation stability is not definitively specified.
Safety
Safety Profile
The CIR Expert Panel has determined that Sesamum Indicum (Sesame) Seed Oil and related derivatives are safe for cosmetic application. Concurrently, the panel assessed 237 alkyl esters, concluding their safety in cosmetic formulations when formulated to be non-irritating. Given the general safety of both the parent oil and the alkyl ester class, Sesame Seed Oil Ethyl Esters are considered safe for use, provided formulation guidelines are followed to prevent irritation.
