Caprylhydroxamic Acid
Caprylhydroxamic Acid
A gentle preservative-booster and chelator that works across a range of pH, letting formulas rely on milder preservative systems.
What it does
Caprylhydroxamic acid helps keep products free of microbial growth and binds metal ions, and it stays effective across a wider pH range than some preservatives. It is frequently paired with glycols in "preservative-free"-style systems. Its role is keeping the formula safe and stable, not acting on the skin.
