【摘要】 介绍了功能性护理品中新型保湿防腐剂-烷基邻位二醇,并对1,2-戊二醇、1,2-己二醇、1,2-辛二醇、1,2-癸二醇的结构与特性,单一组分及复配应用效果做了比较分析。作为个人护理品防腐成分,烷基邻位二醇没有传统防腐成分刺激性大、对皮肤致敏率高的缺陷,具有保湿防腐抑菌多功能特性,并且在当前已有了广泛的应用。此外,二元醇类复合、功效性防腐未来将成为防腐组分开发与应用发展方向。更多还原

【Abstract】 A new type of moist preservatives- alkyl orthodiols used in functional skincare products was introduced.The structures and properties of 1,2- pentanediol,1,2- hexanediol,1,2- octanediol and 1,2- sebacic diol,and their single component and compond application effect were analyzed. As preservative ingredients of personal skincare products,alkyl orthodiols had zero defect of traditional preservative ingredients like irritation and high skin sensitization rate,with multi- functional characteristicsas preserve moisture,anticorrosion and bacteriostasis,and in the current had been used widely. In additional,compound and efficiency anticorrosion effect of dihydric alcohol will be the developing and the applied direction of anticorrosion components in the future.更多还原
