Science
Mechanism of Action
As a mild surfactant, Palm Kernel Acid efficiently cleanses the skin and scalp by lifting and removing impurities without harshness. Its emulsifying capabilities enable the stable blending of oil and water components in formulations, contributing to a smoother product application and enhancing moisturization. Additionally, it acts as a thickening agent and stabilizer, improving product viscosity and creating a richer texture, while also contributing to foam generation.

Key findings
- 01 Fatty acid salts derived from a 50:50 combination of red palm oil (RPO) and palm kernel oil (PKO) demonstrated antibacterial activity. A 30% concentration of these fatty acid salts exhibited optimal antibacterial efficacy against *Propionibacterium acnes* and *Staphylococcus epidermidis*, with a 10% concentration yielding a significant inhibition diameter of 18 mm. While this study relates to derivatives of palm kernel oil, it suggests potential for similar fatty acid compositions.

Formulation
Stability
Palm Kernel Acid generally integrates well with standard cosmetic ingredients such as other surfactants, emulsifiers, and hydrocarbon solvents. Comprehensive compatibility testing is recommended during formulation development to ensure blend stability and prevent phase separation.
Synergies
- Common surfactants
- Emulsifiers
- Hydrocarbon solvents
Conflicts
- High concentrations of free alkaline, specifically above 0.22% or at a pH exceeding 11, may induce skin irritation.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed related ingredients, including Elaeis Guineensis (Palm) Oil and Elaeis Guineensis (Palm) Kernel Oil, safe for use in cosmetic formulations. As Palm Kernel Acid is a mixture of fatty acids derived from Palm Kernel Oil, its safety assessment is informed by these broader evaluations. While Palm Oil was reported at concentrations up to 2%, a specific maximum concentration for Palm Kernel Acid itself was not explicitly stated in the reviewed CIR data, with safety based on reported 'as used' concentrations. Incidence of irritation is low at typical usage levels.
