摘　　要：应用称重法对7种化妆品中的1,2-丙二醇、1,3-丁二醇、丙三醇、甜菜碱、山梨醇保湿性能进行分析,采用气相色谱法对1,2-丙二醇和丙三醇进行定性分析和定量分析.研究结果表明,丙三醇、1,3-丁二醇、1,2-丙二醇比甜菜碱、山梨醇的保湿能力持久,1,2-丙二醇和丙三醇保湿性能较为稳定,丙三醇作为最早使用的传统保湿剂仍被广泛应用.The moisturizing properties 1,2-propanediol,1,3-butanediol,glycerine,betaine,sorbitol in 7 cosmetics were analyzed by weighing method,qualitative and quantitative analysis of 1,2-propylene glycol and glycerine were performed by gas chromatography.The results showed that glycerine,1,3-butanediol,1,2-propanediol had more lasting moisturizing ability than betaine and sorbitol,and the moisturizing performance of 1,2-propanediol and glycerine was more stable.Glycerine was still widely used as the earliest traditional moisturizing agent.
