Capryhydroxamic Acid ●
TL;DR. This ingredient is mainly used as a preservative booster and chelating agent, especially to support protection against yeast and mold. It binds iron, which helps limit microbial growth and can improve overall preservation systems.
What does Capryhydroxamic Acid do in a cosmetic formula?
This ingredient is mainly used as a preservative booster and chelating agent, especially to support protection against yeast and mold. It binds iron, which helps limit microbial growth and can improve overall preservation systems.
Is Capryhydroxamic Acid clean?
It is generally accepted by clean-beauty standards because it is used at low levels, has a low sensitization profile, and is not a common restricted-list material. Some formulas use it alongside glycols, organic acids, or other boosters rather than relying on it alone.
Is Capryhydroxamic Acid sustainable?
This material is commonly made from an eight-carbon fatty acid that may come from coconut, palm kernel, or synthetic feedstocks. It is used at very low concentrations and is expected to have favorable biodegradability, with sourcing quality depending on the fatty-acid supply chain.
Is Capryhydroxamic Acid COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic when the feedstock and processing route meet the standard’s requirements. Its Green Chemistry fit is relatively strong because it can use renewable fatty feedstocks, works at low dosage, and supports preservation without high solvent load.
How does Capryhydroxamic Acid work chemically?
The molecule combines a medium-chain lipophilic tail with a polar nitrogen-oxygen chelating head group, giving it both microbial-control support and metal-binding behavior. Typical use levels are about 0.05% to 0.2%, with broad pH compatibility around pH 4 to 8 and better handling when pre-dissolved in glycols or added with mild heat.
