淀粉糖苷表面活性剂的吸湿保湿性能研究

Study on Moisture-absorption and Moisture-retention Capacity of Starch Glycoside Surfactant

以马铃薯淀粉为糖源,利用转糖苷法合成淀粉糖苷表面活性剂,用重量法测定其吸湿性和保湿性,并与甘油、山梨醇、聚乙二醇、木糖醇、烷基多苷进行比较。结果表明,在30℃,相对湿度43%和相对湿度81%环境条件下,制得的淀粉糖苷表面活性剂的保湿性优于对比试样,72h后保湿率均在70%以上;其吸湿性仅次于甘油,72h后吸湿率达到50%。

The moisture-absorption capacity and moisture-retention capacity of starch-based alkyl polyglycoside surfactant synthesized by trans-glycosylation with hepatin of potato starch were determined by the weight method, and compared with capacities of glycerine, sorbitol, polyethylene glycol, xylitol, and alkyl polyglycosides. The results indicated that, at RH 43% and RH81% , the moisture-retentlon capacity of the starch glycoside surfactant surpasses other samples （30℃）, and its moisture-retention rate reach above 70% after 72h; the moisture-absorption rate of the starch glycoside surfactant is just inferior to the glycerine, reaching 50% after 72h.
