Science
Mechanism of Action
This ingredient primarily operates by chelating metal ions, such as iron, thereby neutralizing their pro-oxidant activity within formulations. This not only preserves product stability but also indirectly offers skin protection. Its biostatic and fungistatic properties contribute to product longevity, remaining active across various pH levels, including elevated alkaline conditions.

Stability
Cinnamoylhydroxamic Acid exhibits high water solubility, estimated at 1.678e+004 mg/L at 25 °C. While generally stable, hydroxamic acids are susceptible to hydrolysis at extremely high or low pH values. The keto form is favored in acidic environments, whereas the enol form tends to dominate under alkaline conditions. Its smooth solubility in alkaline solutions is attributed to the stability of the hydroxamate anion.
Synergies
- Can be effectively integrated with antimicrobial glycols to create robust 'preservative-free preservative systems'.
