Everpro系列防腐剂性能测试

介绍了月桂酰精氨酸乙酯盐酸盐作为一种新型防腐剂在使用时的安全性,研究了月桂酰精氨酸乙酯盐酸盐作为防腐剂时对大肠杆菌、金黄色葡萄球菌和绿脓杆菌的抑菌性能和热稳定性。对添加月桂酰精氨酸乙酯盐酸盐为主要成分的Everpro系列防腐剂的香波、护肤湿巾配方进行防腐性能测试,实验结果表明,以1.0%Everpro~(TM)LCG作为防腐体系的纯氨基酸润泽香波配方和以0.75%Everguard~(TM)LAE-20+0.3%辛甘醇作为防腐体系的洁肤湿巾都能通过防腐挑战测试。

Performance test of Everpro preservatives

The safety of ethyl lauroyl arginate hydrochloride used as a novel preservative was introduced. The thermal stability and the antibacterial effects of ethyl lauroyl arginate hydrochloride on Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa were studied. The antiseptic performances of Everpro preservative series whose major component was ethyl lauroyl arginate hydrochloride were tested in the formulations of shampoo and wet tissue. The experimental results showed that the amino acid shampoo with 1.0% EverproTM LCG as preservative and the wet tissue with 0.75% EverguardTM LAE-20 + 0.3% caprylyl glycol as preservative both showed high antibacterial efficacy.
