茶皂素洗手液的制备及抑菌性能研究

Preparation and bacteriostatic properties of tea saponin hand sanitizer

以茶皂素(TS)为主要抑菌成分,脂肪醇聚氧乙烯醚硫酸钠(AES)和椰油酰胺丙基甜菜碱(CAB)为表面活性剂,通过单因素实验筛选抑菌洗手液配方,并对洗手液理化指标及抑菌性能进行测定。结果表明:优化后的TS洗手液由质量分数为15%TS,10%AES,20%CAB,3%增稠剂886+6502(质量比1∶1),3%甘油,0.1%香精,0.2%柠檬酸和余量去离子水组成,该洗手液黏度适中,起泡性能优异,对大肠杆菌和金黄色葡萄球菌抑菌性能良好。

Tea saponin(TS)was used as the main bacteriostatic component,and fatty alcohol polyoxyethylene ether sulfate(AES)and cocoamidopropyl betaine(CAB)were used as surfactants.The formulation of bacteriostatic hand sanitizer was screened by single factor test,and the physicochemical indexes and bacteriostatic properties of the hand sanitizer were determined.The results show that the mass fraction of optimized TS hand sanitizer is composed of 15%TS,10%AES,20%CAB,3%thickener 886 and 6502(mass ratio 1∶1),3%glycerin,0.1%flavor,0.2%citric acid and residual deionized water.The hand sanitizer has moderate viscosity,excellent foaming performance and good bacteriostatic performance against Escherichia coli(E.coil)and Staphylococcus aureus(S.aureus).
