The Application of a Mixed Nonionic Surfactant Theory to Transitional Emulsion Phase Inversion

摘要: Abstract Transitional emulsion phase inversion in nonionic-surfactant-oil-water systems (nSOW) is brought about by changing the surfactant's affinity for oil and water phases. In this paper an analysis given to explain linearity gradient variation of transitional lines (i.e., surfactant difference vs volume fraction water) containing distributed nonionic surfactants. A simple partitioning model derived which can be applied isothermal inversions where altered ratio a lipophilic hydrophilic system. The describes between oil, water, pseudosurfactant phase, represents at oil-water interfaces. surfactants used study had distribution chain lengths; discusses when type may regarded as single components. these cases lumped parameters describe three number nSOW effect concentration examined. method obtaining CMCs mixed indicated.
