Abstract
Compounds of formula (I), where R.sup.1, R.sup.2, R.sup.3, R.sup.4 and R.sup.5 have defined meanings ##STR1## are useful as surfactants especially in agrochemical formulations, pigment dispersions and domestic detergent formulations. Compounds where one of R.sup.1 and R.sup.2 is hydrogen and the other is C.sub.8 to C.sub.18 straight chain alkenyl group, the group --NR.sup.3 R.sup.4 is the residue of a glycamine, especially a glucamine, and R.sup.5 is --NR.sup.3 R.sup.4 as defined (especially a glycamine residue) or a group O.(AO).sub.n.R.sup.6 where AO is an alkylene oxide, especially an ethylene oxide, residue, n is especially from 3 to 50 and R.sup.6 is a C.sub.1 to C.sub.6 alkyl group, are particularly desirable.
