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
