Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel concluded that PCA and its salts are safe for cosmetic use, provided they are not incorporated into products where N-nitroso compounds could potentially form. While the reported maximum use concentration for related PCA compounds is up to 2.5% in leave-on products and 3% in rinse-off formulations, PCA Ethyl Cocoyl Arginate itself has been specifically noted for its excellent safety profile, exhibiting very low skin and eye irritation even at high concentrations.
