Caprylhydroxamic Acid
Caprylhydroxamic Acid (CAS 7377-03-9) is a chelating agent derived from caprylic acid. It works by neutralizing metal ions—particularly iron—that enter cosmetic formulas via water. It also exhibits biostatic and fungistatic properties and remains active even at high pH levels.

other● Benefits
Helps preserve cosmetic products by chelating metal ions that can destabilize formulas. Its biostatic and fungistatic activity allows it to function as part of a "preservative-free preservative system," often paired with antimicrobial glycols such as propanediol.
