Science
Mechanism of Action
As an emollient, Triundecanoin works by forming a protective layer on the skin's surface, helping to reduce transepidermal water loss and maintain hydration, thereby softening and smoothing the skin. Furthermore, it is noted to enhance the penetration of other ingredients, potentially improving their delivery into the skin.

The Formula
Formulation
Stability
Triundecanoin is a solid with a melting point of 24-32 °C, meaning it can be a solid or a liquid depending on ambient temperature. For optimal stability and to preserve its high purity, storage in a freezer is recommended. It exhibits extremely low solubility in water (3.912e-010 mg/L at 25 °C) but shows slight solubility in certain organic solvents such as chloroform, ethyl acetate, and methanol. The ingredient is produced with minimal volatile compounds, PAHs, and aflatoxins.
