摘要：

以2,3-环氧丙基三甲基氯化铵（GTA）为季铵化试剂,通过季铵化反应赋予超支化葡聚糖植物糖原（PG）阳离子性。通过单因素试验得到优化后的条件为：催化剂氢氧化钠质量分数为0.3%,反应温度为（50±2） ℃,反应时间2 h,GTA与PG质量比为1.2:1,此时反应产物阳离子植物糖原（PG-GTA）取代度可达到0.294。研究了PG-GTA与洗发水中的表面活性剂相互作用的絮凝情况,结果表明,当洗发水被稀释至5倍时有良好的絮凝效果。在此基础上,研究了添加PG-GTA的洗发水的梳理性能,与不加PG-GTA的洗发水相比,梳理功降低了31.29%。

Abstract:

2, 3-epoxypropyltrimethylammonium chloride（GTA） was used as a quaternization agent to prepare the cationic hyperbranched dextran phytoglycogen（PG） through quaternization. The optimized conditions were obtained by single-factor experimental experiment as follows: the mass fraction of sodium hydroxide was 0.3%, the reaction temperature was（50±2） ℃, the reaction time was 2 h, and the mass ratio of GTA to PG was 1.2:1. In such condition, the degree of substitution of cationic phytoglycogen（PG-GTA） could reach 0.294. The flocculation of the interaction between PG-GTA and the anionic surfactant in the shampoo was studied. The results show that the shampoo has a good flocculation effect when diluted to 5 times. On this basis, the combing performance of the shampoo added with PG-GTA was studied, and the combing work was reduced by 31.29% compared with the shampoo without PG-GTA.

Key words: phytoglycogen, quaternization, shampoo, combing work
