The surface tension, interfacial tension, wetting power, and foaming properties of the mixtures of sucrose monostearate and avionics (sodium oleyl-N-methyltaurate, sodium dodecylbenzenesulfonate and sodium dioctylsulfosuccinate) have been investigated.
The CMC values of mixtures were between those of the component surfactants. The surface tension and interfacial tension of the mixtures of sucrose monostearate and oleyl-N-methyltaurate were a little higher than those of the component surfactants at the concentrations above the CMC respectively. The surface tension and interfacial tension of the mixtures of sucrose monostearate and dodecylbenzenesulfonate or dioctylsulfosuccinate were nearly between those of the component surfactants respectively.
The wetting power of sucrose monostearate has been increased by the addition of these avionics.
The foaming power and foam stability of sucrose monostearate have been remarkably increased by the addition of oleyl-N-methyltaurate, but decreased by the addition of dodecylbenzenesulfonate or dioctylsulfosuccinate.
