Description
DropPrev®CHA acts as an organic acid that attacks molds (A.Niger) only when it is dispersed in an undissociated state in the organism. CHA is the only organic acid that remains unionized from acidic to neutral. And it has strong inhibitory effects on the growth of A. Niger. The product has been tested by Intertek, the UK authoritative company, and the results show that the minimum inhibitory concentration of the sample to A. Niger is 780ppm.As a drug, CHA has been applied to animals and humans for a long time. Its toxicology has been studied extensively and deeply, thus it has high safety. So it can be used in cosmeties instead oftraditional preservatives. It remains highly bacteriostatic in neutral pH environments, where most other preservative alternatives are less effective.
Properties
The efficacy of organic acids: it is still effective when pH value is neutral, so it is an ideal organic acid forbacteriostasis;
Chelation effect: DropPrev®CHA has highly selective chelation of Fe2+ and Fe3+ in iron-restricted environment, which limits the growth of mold; The stability constant of CHA chelating Fe3+ is high, which can prevent mold A.Niger obtaining iron elements;
Short chain activity: Like octanediol, it also has the optimal carbon chain length(C8) to promote the degradation of cell membrane structure.
