摘　　要：研究了糖苷基季铵盐(CAPG)与十二烷基硫酸钠(K12)复配体系的稳定性、表面活性、泡沫性能和润湿性能。结果表明:CAPG与K12复配体系的稳定性好,并表现出很好的协同增效作用。当n(CAPG)∶(K12)等于0.1∶1,0.3∶1,0.5∶1时,复配体系的临界胶束浓度(cmc)分别为0.081 mmol/L,0.065 mmol/L,0.054 mmol/L,大大低于单一组分的cmc,临界胶束浓度时的表面张力(γcmc)比单一组分略低,起泡力和泡沫稳定性均好于单一组分,润湿力比K12略低,但比CAPG好得多。Surfactant activity, compatibility,foaming properties and wetting power were investigated for mixed systems of glucoside quaternary（CAPG） and sodium dodecyl sulfate（ K12 ）. It was found that mixed systems of CAPG and K12 had a good compatibility and showed a strong synergic effect. When n （ CAPG ） ： n （ K12 ） was 0. 1 ： 1,0.3 ： 1,0.5 ： 1, critical miceUe concentration （ cmc ） of mixed systems was 0.081 mmol/L, 0. 065 mmol/L, 0. 054 mmol/L respectively, which much lower than that of the single one; surface tensions of mixed systems （ γcmc ） were also lower than that of single surfactant; foaming ability and stability of foam of mixed systems were better than that of any single component;wetting power of mixed systems were a little lower than that of K12 ,but much better than that of CAPG.
