Abstract
The solubility of benzaldehyde, methyl linoleate and cyclohexene in solutions of potassium laurate and cetomacrogol is reported. A marked increase in the solubility of these water-insoluble materials was observed in solutions of potassium laurate above the critical micelle concentration (CMC). In cetomacrogol, the CMC could not be detected from inspection of the solubility curves, since the solubility was a function of cetomacrogol concentration over the entire concentration range studied. The solubility of methyl linoleate and cyclohexene was directly proportional to cetomacrogol concentration. The solubility curve of benzaldehyde showed a steep rise at low concentrations of cetomacrogol, and the possibility of this being due to a water soluble complex between benzaldehyde and cetomacrogol is discussed. The effect of temperature and the presence of sodium chloride on benzaldehyde solubility is reported.
