Science
Mechanism of Action
As a fatty acid, Peanut Acid contributes to skin moisturization by providing emollient properties, aiding in barrier function support. In cosmetic formulations, it acts as a surfactant, reducing surface tension to facilitate cleansing, and as an emulsifier, stabilizing oil-in-water or water-in-oil mixtures.

Conflicts
- May enhance the dermal absorption of other compounds, requiring careful formulation assessment.
- Requires strict control of aflatoxin and residual peanut protein levels by formulators.
- May not be suitable for individuals with Malassezia Folliculitis (fungal acne) due to potential exacerbation.
Safety
Safety Profile
The CIR Expert Panel has concluded Peanut Acid is safe for use in cosmetic formulations. However, the SCCS restricts the maximum level of peanut proteins in Peanut Oil, its extracts, and derivatives (including Peanut Acid) to 0.5 ppm in cosmetic products due to concerns regarding potential allergic reactions. This restriction became effective on September 25, 2018. The FDA generally requires cosmetic ingredients to be declared on labels but does not typically approve cosmetic ingredients prior to marketing, with no specific pre-market approval for Peanut Acid.

Verdict
Peanut Acid is a versatile functional ingredient offering moisturizing, cleansing, and emulsifying properties, though formulators must carefully manage potential allergen concerns (due to residual peanut protein) and its moderate comedogenicity.
