The salt effects of 10 transition metal cations on nonionic surfactants were investigated by the action of their salts (nine nitrates, two sulfates) on the cloud point (CP) of octoxynol 9. All cations investigated raised the CP of octoxynol 9 by complexation with its ether groups, which represents s

As an alternative, salt effects for NS are measured by The effect of salts on the nonionic surfactant octoxynol 9 was changes in CMC or in CP. Most NS have small CMC values. studied by the changes they produced in its cloud point (CP): CP Therefore, the increases in CMC through salting in and the in
The effect of electrolytes and urea on the cloud points of the following three nonionic polyoxyethylated surfactants was studied: cetyl, stearyl, and oleyl alcohol adducts containing 10 ethylene oxide units. The results were similar to those obtained previously with polyethylene oxide and with a pol
