【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。更多还原

【Abstract】 2-Hydroxypropyltrimethyl ammonium chloride chitosan(HACC) was prepared using 2,3-epoxypropyl trimethylammonium chloride as a grafting agent in 2-propanol from chitosan(CTS) with degree of deacetylation 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.更多还原
