Solubilization by Nonionic Surfactants in the HLB-Temperature Range
A general pattern is presented of the solubilization of hydrocarbons in nonionic surfactants and water in HLB-temperature range. The separation of a third phase, the surfactant phase, with increasing temperatures gives a rational explanation to the ultra-low interfacial tensions between the water and the hydrocarbon solutions, which has been observed in these systems. Light scattering determinations gave evidence of a new kind of micellar aggregation in the liquid emulsifiers with added water. In contrast to the regular inverse micelles these aggregations show marked anisotropic properties.
