Abstract
Solubilization of water by mixed nonionic and anionic or cationic surfactants in nonaqueous solutions was studied as a function of the temperature. Nonionic surfactants of hydrophobic property broadened the solubilization region of water at higher temperature by mixing with the anionic surfactant (Aerosol OT). On the other hand, by hydrophilic nonionic surfactants broadened the solubilization region at lower temperature by mixing.
In the mixed cationic and nonionic surfactant solutions, the solubilization region in cationic surfactant solutions narrowed by addition of polyoxyethylated nonionics, whereas that broadened markedly by mixing with both glycerol and sorbitan mono-oleates.
