| Use | 1) Safety: CHA's raw materials are sourced from coconut oil, which is a natural preservative with high safety. CHA has a long history of being used as a drug in animals and humans, and its toxicity has been extensively and deeply studied. It can replace traditional preservatives and be compounded with polyols to form a non additive preservative system for use in cosmetics and personal care products. 2) The efficacy of organic acids: CHA remains effective even at neutral pH, making it an ideal antibacterial organic acid. Organic acids can only attack A. Niger when dispersed in an undissociated state within an organism, and CHA is the only organic acid that remains in an undissociated state throughout the entire process from acidic to neutral. 3) Chelation effect: CHA has a highly selective chelation effect on Fe2+and Fe3+, and the growth of microorganisms will be reduced in an environment limited by iron ions. CHA effectively inhibits the growth of mold A. niger. This product has been tested by Intertek in the UK and the results show that the minimum inhibitory concentration of CHA against Aspergillus niger is 0.078%. 4) Short chain activation function: Like octanediol, it also has a carbon chain length (C8) that can promote the degradation of cell membrane structure. |
