ABSTRACT:
A water-in-oil emulsion of a cationic polymer suitable for inversion, comprising a continuous phase comprising a hydrophobic liquid, a discontinuous phase comprising a water-soluble cationic polymer, and a surface active agent system for inventing the emulsion in water, the system comprising a mixture of at least one alkyl phosphate represented by formula (I) or (II) and at least one other surface active agent compatible with the at least one alkyl phosphate: ##STR1## wherein R.sub.1 represents a saturated or unsaturated hydrocarbon group having from 8 to 18 carbon atoms; X and Y, which may be the same or different, each represents a hydrogen atom, an alkali metal, an ammonium group, or an alkanolamino group; and n1 represents 0 or an integer of from 1 to 4; ##STR2## wherein R.sub.2 and R.sub.3, which may be the same or different, each represents a saturated or unsaturated hydrocarbon group having from 8 to 18 carbon atoms; X represents a hydrogen atom, an alkali metal, an ammonium group, or an alkanolamino group; and n2 and n3 each represents 0 or an integer of from 1 to 4.
