Abstract:The stability, surface activities and application performances of dodecyl trimethyl ammonium hydroxide (DTAH) and alkyl polyglycoside surfactant mixed systems were measured. The results show that the transmittance of mixtures over 80% when the active matter content of mixtures below 70 g/L, indicate the mixtures show good stability. The critical micelle concentration and surface tension of mixtures have lower value than single surfactant solution. And the mixtures show better foaming abilities, emulsifying properties, wetting properties and clearing power than DTAH.
