Solution behavior and hydrophile-lipophile balance temperature in the aerosol ot-isoctane-brine system: correlation between microemulsions and aerosols
It becomes evident from studies of the solution behavior of aerosol ot-oil-water containing salt that there exists a temperature at which the hydrophile-lipophile balance (HLB temperature) of adsorbed surfactant monolayer just balances toward a given oil-water system in a solution of a balanced ionic surfactant as well as nonionics. Interestingly enough, however, the effect of temperature reverses. From the studies of phase volumes of water (or oil) and surfactant as a function of temperature at various concentrations of aerosol ot, it is clear that a phenomenon similar to a critical solution occurring between water and surfactant as well as oil and surfactant and ultralow interfacial tension in the HLB temperature range can be explained by this critical phenomenon. The HLB temperature is a function of the type of oil, the concentration of salts, etc. 22 references.
