Caprylhydroxamic Acid description
Caprylhydroxamic acid is a synthetic chelating agent that helps protect cosmetic formulas from destabilizing metal ions. It also works as a preservative, having the ability to prevent mold growth in water-based formulas. This ingredient has great flexibility since it works in all types of cosmetic formulas, including waterless (anhydrous) and its efficacy is not pH-dependent. It is sometimes combined with humectants such as glycerin or propanediol to support aesthetics or a more conventional, broad-spectrum preservative system. Recommended usage levels of caprylhydroxamic acid go from 0.05–0.25% in leave-on and rinse-off products. A draft report by the Cosmetic Ingredient Review board indicates this ingredient is safe and non-irritating as currently used in cosmetics.
