摘　　要：三羟基硬脂精常用作植物油、食用色拉油和烹调油的抗结晶剂,并具有更安全、成本更低等优点。研究发现将其作为悬浮剂应用于二合一洗发香波中,相比常用的香波悬浮剂,生产工艺操作简便,成本更低。本文对三羟基硬脂精、卡波姆(Carbomer 940)、丙烯酸(酯)类/C;烷醇丙烯酸酯交联聚合物(Ultrez 21)、丙烯酸(酯)类共聚物(Aqua SF-1)和二(氢化牛脂基)邻苯二甲酸酰胺(TAB-Ⅱ)在二合一香波中的应用进行了研究,对三羟基硬脂精在实际应用过程中对二合一香波的稳定性、泡沫力、梳理性、黏度和产品使用体验感进行了数据化表征。同时,通过红细胞溶血实验和人体安全性斑贴实验对三羟基硬脂的刺激性进行研究。结果表明,三羟基硬脂精具有较高的温和性,并能够缓解香波的刺激性;添加0.2%的三羟基硬脂精作为悬浮剂便可以制得稳定的含珠光片、硅油、吡硫鎓锌的二合一香波,且不影响香波的使用感受。Trihydroxystearin is a kind of food additive which is safe and inexpensive. It has been widely used as an anti-crystallizer for many types of oils, such as vegetable oil and edible salad oil. In daily chemical products, trihydroxystearin can effectively provide thixotropy and prevent the occurrence of sedimentation. Recent research has shown that it can be used as a suspending agent in wash and protect, two-in-one shampoos. As a suspending agent, trihydroxystearin is effective to suspend silicone oil, pearlescent agents, anti-dandruff agents and other shampoo components. Compared with other commonly used suspending agents for shampoos, trihydroxystearin is more convenient and has less influence on the physical and chemical properties of the shampoos. Herein, a comparative study for the application of trihydroxystearin and other suspending agents, such as carbomer(Carbomer 940), acrylate/C;alkyl acrylate cross-linked polymer(Ultrez 21), acrylate copolymer(Aqua SF-1) and dihydrogenated tallow phthalic acid amide(TAB-Ⅱ), in 2-in-1 shampoo was made. Carbomer 940 and Ultrez 21 tend to absorb moisture and agglomerate. For Aqua SF-1, it is difficult to eliminate the foam produced by shearing and stirring in large-scale production, which leads to long de-foaming time and high energy consumption. TAB-Ⅱ can reduce the foaming properties and cleaning ability of shampoos. Therefore, trihydroxystearin is more suitable for use as a suspending agent in a lotion, and as a stabilizer in a two-in-one shampoo compared with the chemicals mentioned above. The results show that, stable two-in-one shampoo can be made by adding 0.2% trihydroxystearin as the suspending agent, the amount of which is less than other suspending agents. The safety of trihydroxystearin was studied by using the red blood cell hemolysis test and the human safety patch test. The results show that trihydroxystearin can decrease the irritation of surfactants in the red blood cell hemolysis test, and it has not irritation to the skin in the human safety patch t
