CAPRYLHYDROXAMIC ACID is graded A (Safe) by Expert·ING, based on COSING, FDA regulatory data.
CAPRYLHYDROXAMIC ACID
Safety grade: A
Caprylhydroxamic acid is a synthetic preservative booster derived from caprylic acid (a natural fatty acid found in coconut oil). It works by binding to trace metals in formulas that could otherwise cause spoilage or discoloration.
As a chelating agent, it binds to metal ions in cosmetic formulas to prevent them from triggering oxidation and degradation, which helps preserve the product's stability and extends its shelf life.
