N-Hydroxyoctanamide  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 ideal orgnic acid.
Chelating effect: CHA has a strong chelating power to Fe2+ and 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, and capture Fe3+ and 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 of organic acid, it exists as undissociatedmolecule in organisim.
CHA is a kind of organic 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 and animals. Its toxicology has been widely studied.
It could be used as a replacement for traditional 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 for cosmetics. In a test it shows that its capacity for anti-bacterial can not be influenced by surfactants, protein or some other additions in cosmetics; Yet it did have chemical reaction with Fe3+ in clay from  bentonite, ganister sand and so on. More Fe3+ was found, the darker the color will be. Therefore EDTA-2NA is suggested to be added in the formula.  

Application: caprylhydroxamic acid may be used in emulsion. Anhydrous and surfactant systems. These include creams, lotions, shower gels and make-up. It may be added to the water phase , at ambient or hot temperatures, or may be added post-emulsidication of O/W emulsions.
we do recommend avoiding lengthy exposure to elevated temperatures: for example, maximum two hours at 90°C,or maximum six hours at 60°C.
Dosage: 0.05—0.15%
