Science
Mechanism of Action
As a fatty acid dimer, Dilinoleic Acid conditions the skin by supporting its natural moisturizing capabilities and contributing to improved skin elasticity. It aids in creating a smoother skin surface and its derivatives are known to fortify the skin barrier, forming a protective film that softens and smooths the complexion.

Stability
Due to its polyunsaturated structure, Dilinoleic Acid is susceptible to oxidation, which can shorten product shelf life. Formulations should integrate antioxidants for protection, and the ingredient should be stored in a tightly sealed container under an inert atmosphere, ideally refrigerated and shielded from light.
Safety
Safety Profile
The CIR Expert Panel has determined Dilinoleic Acid to be safe for cosmetic use, provided it is formulated to prevent irritation and sensitization. While direct maximum concentration for the acid is not specified, related derivatives have been safely incorporated into cosmetics at concentrations up to 29% (e.g., Diisopropyl Dimer Dilinoleate in lipsticks). Despite one reported case of sensitization, the overall safety profile is considered favorable.
