摘要
以脱乙酰度为95.37%的壳聚糖(CTS)为原料,异丙醇为溶剂,2,3-环氧丙基三甲基氯化铵为改性剂,于80℃反应12 h合成了水溶性季铵盐2-羟丙基三甲基氯化铵壳聚糖(HACC)。HACC的吸水保水性是CTS的2倍～3倍,加入化妆品中培养2周后菌落总数少于100 CFU.g-1。
2-Hydroxypropyhrimethyl ammonium chloride chitosan （ HACC ） was prepared using 2,3- epoxypropyl trimethylammonium chloride as a grafting agent in 2-propanol from ehitosan （CTS） with degree of deaeetylation of 95.37% at 80 ℃ for 12 h. The moisture retention capacity and moisture absorbability of HACC was two to three times that of CTS. The amount of the microbiology was less than 100 CFU ·g^-1 two weeks after adding the HACC into cosmetic.
