Caprylhydroxamic acid

Caprylhydroxamic acid is a naturally derived, plant-based preservative alternative used in skincare and cosmetic formulations. It is derived from coconut oil and works as a mild yet effective antimicrobial agent, preventing the growth of mold, yeast, and bacteria in water-based products. Unlike traditional preservatives like parabens or formaldehyde-releasing agents, caprylhydroxamic acid is considered a safer, more skin-friendly option for preserving skincare formulations.

This ingredient functions by chelating iron ions, which microbes need to survive, effectively disrupting their ability to grow. It is often combined with other mild preservatives and emollients, such as caprylic/capric triglyceride, to create broad-spectrum preservation systems. Additionally, caprylhydroxamic acid is non-irritating and suitable for sensitive skin, making it a preferred choice for clean beauty formulations and natural skincare products.

Beyond its preservative function, caprylhydroxamic acid has mild moisturizing properties, helping to maintain skin hydration while keeping products fresh and stable. It is commonly found in creams, serums, and lotions, particularly in formulations designed to be free from synthetic preservatives. Its effectiveness in low concentrations makes it an efficient and gentle option for ensuring the longevity and safety of skincare products.
