Ingredient Info

Caprylhydroxamic Acid is a preservative and chelating agent used in skincare products to prevent microbial growth and extend shelf life. It's a multifunctional ingredient increasingly used as an alternative to traditional preservatives in formulas designed for sensitive skin.



Benefits

  • Preserves products by preventing bacterial and microbial growth
  • Chelates metal ions that can degrade product quality
  • Gentler alternative to some conventional preservatives, particularly for sensitive skin formulations

Potential concerns

  • May cause skin sensitization, especially when applied to damaged or compromised skin
  • Requires careful formulation to minimize skin penetration and reduce irritation potential

Science: The Expert Panel for Cosmetic Ingredient Safety concluded that Caprylhydroxamic Acid is safe at current usage levels and concentrations, but advised caution against formulations that increase skin penetration. Research shows it is used at safe levels in infant and sensitive-skin cosmetics as a preservative alternative.
