摘　　要：考察了钙皂分散剂N-十二烷基-N,N-二甲基-N-(p-苄磺基)甜菜碱(DSBB)与透明皂基的配伍性,测定了复配体系的抗硬水度、钙离子稳定性、去污力、泡沫性能、润湿性能和水溶温度。实验结果表明:由于DSBB的钙皂分散力高达3,在透明皂基中添加质量分数为10%的DSBB就能明显提高皂基的抗硬水性、去污力和润湿力;加入DSBB也有利于提高复配体系的低温水溶性,同时不会明显降低皂基的泡沫性能。Compatibility of a lime soap dispersing agent, N - dodecyl - N, N - dimethyl - N - （p - sulfobenzyl） betaine （DSBB） with transparent soap base was investigated, and the performances of resistance to hard water, calcium tolerance, detergency, foaming power, wetting power and critical solution temperature were measured. Experimental results showed that lime soap dispersing power of DSBB was as high as 3. When the transparent soap was blended with 10% （mass fraction） of DSBB, the resistance to hard water, the detergency and the wetting power of the mixture were remarkably improved. DSBB was found beneficial to improve the solubility of the soap in cold water and without reducing the foaming power significantly.
