Ingredient

Caprylhydroxamic Acid

A gentle, broad-spectrum preservative booster derived from coconut fatty acids.

Caprylhydroxamic acid is a chelating and antifungal agent that enhances the efficacy of other preservatives. It works by binding iron essential for microbial growth, particularly fungi. It is compatible with a wide pH range and is often used in “preservative-free” systems alongside 1,2-hexanediol and caprylyl glycol.
