摘　　要：研究了十八烷基甲基二羟乙基溴化铵(OMDAB)分别与十二烷基硫酸钠(SDS)、十二烷基苯磺酸钠(LAS)、甜菜碱复配体系的稳定性、表面张力及协同作用。结果表明,在很稀的溶液中复配体系表现出良好的稳定性。与LAS、SDS及甜菜碱复配后表面张力均比单一组分的表面张力低。OMDAB/SDS体系和OMDAB/LAS体系的泡沫性能、乳化性能和柔软性能有显著的增效作用,润湿性能无增效作用。OMDAB/甜菜碱体系的泡沫性能、乳化性能和润湿性能增效作用显著,柔软性能和杀菌性能增效作用并不显著。可以考虑在洗涤剂中加入少量的OMDAB,既可以提高洗涤剂的功效和档次,同时也可降低生产成本。The stability, surface tension and synergy of the mixed systems based on OMDAB blended with sodium dodeeyl sulfate （SDS）, dodecylbenzenesulfonate acid sodium （LAS） and betaine respectively were studied. The results show that the mixed systems exhibited good stability in the very dilute solution. The surface tension of the mixed systems was lower than that of the single components. The foaming property, emulsifying property and softening property of the systems of OMDAB/SDS and OMDAB/LAS had significant synergistic effect, while the wetting property exhibited no such effect. The foaming property, emulsifying property and wetting property of the system of OMDAB/betaine had significant synergistic effect, while the synergistic effect of the softening property and antibacterial property was not so significant. So it is feasible to add a small amount of OMDAB to detergent, which can improve the efficiency and level of the detergent and also reduce the production cost.
