摘要: 壳聚糖是从虾、蟹等废弃甲壳中提取得到的一种生物活性物质,由于其特有的直链聚阳离子结构,成膜附于角蛋白与类脂质上,既在高温状态下稳定,又有一定的水分调节功能.壳聚糖无毒、无味有抑菌作用,配入化妆品中,可提高产品的成膜性,具有抑菌、保湿功能,又不引起任何的过敏刺激反应.但壳聚糖与透明质酸相比,其吸湿、保湿效力较差,本文通过对壳聚糖的结构修饰,在壳聚糖分子中引入经丙基三甲基抓化钱基团,增强壳聚糖的水合能力,提高其吸湿、保湿效能.

Abstract: The reaction of chitosan with 2,3-epoxypropyl trimethylammonium chloride in neutral condition gave 2-hydroxyl-3-trimethyl(ammonio)propyl chitosan chloride. The effects of reaction time on the wetting ability were studied. The chitosan derivatives show good hygroscopic property and moisture retentiveness like hyaluronic acid. They have good solubility in water and good compatibility with non-ionic and cationic surfactants.

Key words: chitosan quaternary ammonium salt, chitosan derivative, hygroscopic property, moisture retentiveness
