Polyethylene glycol esters and amides of polymerised fatty acids are useful dispersing agents for solids, particularly particulate solids e.g. agrochemicals, oil drilling mud components, pigments, personal care formulants, ceramics, magnetic materials, extenders, fillers, optical brighteners, textile auxiliaries, or soil removed from clothes during cleaning, in aqueous media. Particular such agents are of the formula (I): [Pol]-(COX)
m
(I), where: Pol is the core residue of a polymerised fatty acid; m is 2 or 3; and each X is: OM; where M is H, a cationic salt forming species or a group —(AO)
