Caprylhydroxamic Acid is an amino acid derived from coconut oil. It functions as a chelating agent that helps to preserve cosmetic products by neutralizing the metal ions in formulas. However, it also acts as a biostatic and fungistatic agent and remains active even at high pH. So, it can be considered a preservative or a preservative booster too.
