Product Description

Caprylhydroxamic Acid - ( CHA )
In view of the various questions and challenges of traditional preservatives, Caprylhydroxamic
Acid (CHA) has gradually entered the attention of people, because it has been used as a drug in
animals and human bodies for a long time, its toxicology research is very extensive and in-depth,
and has high safety. It can replace traditional preservatives in cosmetics.
 

INCI NAME Molecular formula Molecular weight CAS No.

Caprylhydroxamic Acid C8H17NO2 159.23 7377-03-9

Advantage
1. Because of its good bacteriostatic effect in acid medium, it has the function that other
preservatives do not have.
2. Chelate 3 ferric ions, and 3 ferric ions are the main source of promoting mold;
3. It has good compatibility with most cosmetic materials and good compatibility effect.

The anti-corrosion mechanism
Efficacy of organic acids: It is still effective when the pH value is neutral, and is an ideal
organic acid for inhibiting bacteria. Organic acids can attack mold (A. niger) only in an
undissociated state, while CHA is the only organic acid that remains undissociated under acidic
to neutral full range. It is still highly effective in the pH neutral environment, and the efficacy of
most of the other preservative alternatives in this environment is not ideal.

Specifications



Compatibility
CHA has good compatibility with most cosmetic raw materials. The results showed that its
bacteriostatic ability was not affected by surfactants, proteins and Chinese herbal medicine in
cosmetics. However, it reacts with clay raw materials such as Fe3 from bandeled soil and silicon
powder, which may produce a slight and imperceptible orange-red change. The higher the Fe3
content, the more obvious the color may become. Therefore, it is suggested that DTA-2Na
should be added as chelating agent.
Usage
The invention can be used for emulsifying system, anhydrous formulation and surface active
agent washing system, such as cream, emulsion, body wash, shampoo and make-up, etc. It
can be used for emulsifying system, anhydrous formulation and surfactant washing system,
such as cream, emulsion, body wash, shampoo, and make-up, etc. It is dissolved in the
above-mentioned diol or propylene glycol and glycerin, can be added at normal temperature or
high temperature, and can be added after the system is emulsified. PH value is used in range of
2-8, and the activity is gradually reduced with the increase of PH value. Weak.
It is recommended to avoid high-temperature long-time operation, no more than 2hr at 90 ºC,
and no more than 6hr at 60 ºC.
It is suggested that the addition amount is 0.05-0.15%.
