A series of cationics derived from chloromethylated 2-ethylhexanol-propylene oxide adducts and various amines were prepared and the surface activities-surface tension, foaming properties, wetting power and emulsifying power-were measured. The effects of the moles of propylene oxide added and the varieties of amines on the surface activities were studied and the following conclusions were obtained. 1) The cationics derived from propylene oxide adducts and the amine having OH group, especially, show low values on surface tension as compared with the cationics derived from chloromethylated 2-ethylhexanol. 2) On foaming power the cationics derived from the amine having OH group show high values and those having alkyl and phenyl group show low values. The propylene oxide adducts show low values on foaming stability. 3) On wetting power the cationics derived from propylene oxide adducts show good values, especially, for those with amine having OH group. 4) The addition of propylene oxide improves the dispersing power. And the cationics derived from amine having phenyl group show good values regardless to the moles of propylene oxide added. 5) On emulsifying power the cationics having two long alkyl groups are superior, comparatively.
