Caprylhydroxamic Acid Glyceryl Caprylate ●
TL;DR. This ingredient is primarily used as a preservative booster system, combining antimicrobial support with chelation and some emollient, co-emulsifying benefits. It is often used to broaden protection in water-containing formulas, especially alongside other preservation supports.
What does Caprylhydroxamic Acid Glyceryl Caprylate do in a cosmetic formula?
This ingredient is primarily used as a preservative booster system, combining antimicrobial support with chelation and some emollient, co-emulsifying benefits. It is often used to broaden protection in water-containing formulas, especially alongside other preservation supports.
Is Caprylhydroxamic Acid Glyceryl Caprylate clean?
From a clean-beauty perspective, it is generally viewed as an acceptable alternative to more debated preservative systems, with relatively low sensitization concern at normal use levels. The main caveats are possible eye or skin irritation in leave-on formulas at higher levels and certification friction in stricter natural standards.
Is Caprylhydroxamic Acid Glyceryl Caprylate sustainable?
This material is typically made from a mix of fatty-chain feedstocks and synthetic processing, with the fatty portion often traceable to coconut or palm sources. It has better biodegradability expectations than many persistent preservation technologies, but palm sourcing and limited public aquatic data keep it from being a clear green-tier material.
Is Caprylhydroxamic Acid Glyceryl Caprylate COSMOS-approved?
This ingredient has partial COSMOS alignment: the lipid monoester portion can fit natural-standard rules when feedstock and processing meet requirements, while the antimicrobial chelator portion is not a standard COSMOS-listed preservative. From a Green Chemistry lens, it benefits from efficient low-dose use and fatty-chain sourcing, but it is not a fully renewable or universally certifiable preservation system.
How does Caprylhydroxamic Acid Glyceryl Caprylate work chemically?
This paired system combines a C8 fatty-acid monoester of glycerin with a metal-binding N-hydroxy amide structure that supports preservation by disrupting membranes and limiting metal-dependent microbial growth. Typical total use is often around 0.5% to 1.5%, with best performance in mildly acidic to neutral formulas and better dispersion when pre-solubilized in glycols, emulsions, or oil-compatible phases.
