Compounds of formula (I), where R?1, R2, R3, R4 and R5¿ have defined meanings are useful as surfactants especially in agrochemical formulations, pigment dispersions and domestic detergent formulations. Compounds where one of R?1 and R2¿ is hydrogen and the other is C¿8? to C18 straight chain alkenyl group, the group -NR?3R4¿ is the residue of a glycamine, especially a glucamine, and R?5 is -NR3R4¿ as defined (especially a glycamine residue) or a group O.(AO)¿n.R?6 where AO is an alkylene oxide, especially an ethylene oxide, residue, n is especially from 3 to 50 and R6 is a C¿1? to C6 alkyl group, are particularly desirable. |
