Science
Mechanism of Action
As a humectant, the PCA component actively participates in the skin's natural moisturizing factor (NMF), drawing and retaining water within the stratum corneum to regulate surface hydration. This action supports proper skin cell adhesion, thereby reinforcing the skin barrier and contributing to overall skin integrity and comfort. Concurrently, its cocoyl-derived surfactant portion reduces surface tension, facilitating the fine dispersion of oil in water, enabling gentle cleansing, efficient foam generation, and stabilization as an emulsifier.

Safety
Safety Profile
No direct CIR safety assessment for Potassium Cocoyl PCA was found. However, Potassium PCA, a constituent component, has been affirmed as safe by the CIR Expert Panel for cosmetic use, with usage concentrations reviewed between 0.005% and 0.75%. A critical caveat is its incompatibility with nitrosating agents, which could lead to nitrosamine formation. Specific SCCS or FDA status for the complete ingredient is not documented.
