99%min

CAS NO.7377-03-9

synonym: Caprylohydroxamic acid; N-hydroxyoctanamide; Caprylhydroxamic Acid;7377-03-9

Molecular  Formula:C8H17NO2

Molecular Weight:159.23

Antibacterial Property:Stronger inhibition to mould growth

Product Properties:
Organic acid effect: It workes well when the PH value keeps neutral, which is an idealgnic acid.
Chelating effect: CHA has a strong chelating power to Fe2+ Fe3+. The limitation of iron ion will influence the growth of Mould; Iron ion is crucial to the growth of microorganism. Microorganisim will release siderophores, capture Fe3+ make it changed into Fe3+; CHA has a stronger stability in chelating Fe3+, so that it could effectively prevent mould from combination with iron ion.
Short Chain Surfactant: It has the best length of carbon chain to degrade the cell structure just as octylene glycol. As a kind ofganic acid, it exists as undissociatedmolecule inganisim.
CHA is a kind ofganic acid that keeps in a non-ionization state when the PH varies from acidity to neutral..
CHA could strongly prevent the growth of mould. In a test it shows that the minimum antibacterial density is 0.078%
CHA has a long history served as a king of medical treatment in both human animals. Its toxicology has been widely studied.
It could be used as a replacement ftraditional preservative in cosmetics. It still has a highly effective anti-bacterial capability in neutral environment. However when under the same circumstances, the others will be weakened. 
Compatibility : CHA is compatible with most of the agents fcosmetics. In a test it shows that its capacity fanti-bacterial can not be influenced by surfactants, protein some other additions in cosmetics; Yet it did have chemical reaction with Fe3+ in clay from  bentonite, ganister sso on. More Fe3+ was found, the darker the colwill be. Therefore EDTA-2NA is suggested to be added in the formula.   

we do recommend avoiding lengthy exposure to elevated temperatures: fexample, maximum two hours at 90°C,maximum six hours at 60°C.

Dosage: 0.05—0.15%
