Mechanism of Action
Functioning as a skin-conditioning agent, pelargonic acid contributes emollient benefits that result in a smoother skin texture and an improved tactile sensation. Furthermore, it exhibits mild anti-inflammatory activity capable of calming irritated skin and possesses antibacterial properties, which are valuable in formulations targeting acne.

Stability
Pelargonic acid has a pKa of 4.94, with a 0.1 g/l aqueous solution exhibiting a pH of 4.4 at 25 °C. It is predominantly soluble in organic solvents and shows minimal solubility in water.
Conflicts
- Keep away from excessive heat.
- Formulators should exercise caution when combining pelargonic acid with other ingredients for which enhanced dermal absorption is a concern, as it may increase their penetration.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that pelargonic acid and its esters are safe for use as cosmetic ingredients. It is not considered genotoxic, a reproductive or developmental toxicant, or a sensitizer. At concentrations of 12% and below, it does not induce dermal irritation. However, it may increase the dermal penetration of other ingredients, a factor to consider in formulation.
