    • The invention provides a salt that is in a liquid state at a temperature below 150°C and in which the anion has one of the general formulae

               R a .P(O).O 2 2-

               R a .P(O).(OR b ).O -

               R a .R b .PO -

               (R a O)(R b O).PO -

               (R a O).PO.O 2 2-

      in which one of R a and R b represents an alkyl, alkenyl or alkynyl group having at least 8 carbon atoms, which may be unsubstituted or substituted by one or more substituents selected from halogen atoms, hydroxyl groups, and phenyl groups, and which may be optionally interrupted by one or more oxygen atoms; and the other of R a and R b (if present) has one of these meanings or represents a C 1-7 alkyl, alkenyl or alkynyl group, which may be unsubstituted or substituted by one or more substituents selected from halogen atoms, hydroxyl groups, C 1-4 alkoxy groups, and phenyl groups. Such salts are useful as surfactants, and may be used to prepare emulsions and foams.
