Caprylhydroxamic Acid（or CHA for short ）
Antibacterial performance: high-efficiency inhibition of mold. Octyl hydroxamic acid was detected by Intertek Company in England. The results showed that the minimum inhibitory concentration of the sample against Aspergillus Niger was 0.078%. Octyl hydroxamic acid has high safety and is widely used in Europe, America, Japan and South Korea.
●When CHA is used as a preservative, it should be compounded with bacteria and yeast inhibitor glycols, such as phenoxyethanol, phenylethanol, 1,2-octanediol, octanoic acid monoglyceride, ethylhexyl glycerol, etc., to achieve broad-spectrum antibacterial effect. It can be used in emulsion system, anhydrous formula and surfactant washing system, such as cream, lotion, shower gel, shampoo and make-up.
●Recommended dosage: 0.05-0.15%.
●Usage: After being dissolved in the above diol, propylene glycol and glycerin, it can be added at normal temperature or high temperature, and it can also be added after being used as O/W emulsion or cream. The application range of PH value is 2 ~ 8, and the activity gradually decreases with the increase of PH value.
●Solubility: It is soluble in propylene glycol, glycerin and surfactant.
●Precautions: It is recommended to avoid long-term operation at high temperature, which should not exceed 2hr at 90℃ and 6hr at 60℃.
●CHA has good compatibility with most cosmetic raw materials.
●The experimental results showed that its antibacterial ability was not affected by the additives such as surfactants, proteins and Chinese herbal medicine in cosmetics. However, it may react with a small amount of Fe3+ in clay raw materials such as bentonite and silica powder to produce a slight imperceptible orange color change. The higher the Fe3+ content is, the more obvious the color change may be.
●It is suggested to add EDTA-2Na as chelating agent in the formula。
