摘　　要：以聚羧酸盐(玉米淀粉氧化产物)作洗涤助剂,用表面张力法测定了新型聚羧酸盐与三聚磷酸钠聚丙烯酸钠对硬脂酸钠在硬水中的临界胶束浓度(CMC),以此为依据评价其助洗效率。结果表明,助洗效率按三聚磷酸钠、新型聚羧酸盐、聚丙烯酸钠递减。新型聚羧酸盐具有良好的助洗效果,对环境无污染,可作为洗涤助剂的主选品种。One kind of sodium polyearboxylate containing carboxyl has been gained by corn starch is oxidated by oxygen directly, using it as auxiliary detergent. The influences of novel sodium polycarboxylate, sodium tripolyphosphate and sodium polyacrylate as detergent auxiliary agent on the critical micelle concentration （CMC） of sodium stearate in hard water were studied by use of surface tension method. The evaluation of their washing aiding efficiency was also made. It showes that the decrease order of washing aiding effectiveness is sodium tripolyphosphate, novel sodium polycarboxylate and sodium polyacrylate. Novel sodium polycarboxylate by oxidized corn starch should be taken as main detergent auxiliary agent for its superiority of higher washing aiding activity and non-pollution to the environment.
