ABSTRACT:
A surfactant comprising a carboxylic acid ester or amide carrying a terminal strong acid group selected from carboxymethyl, sulphate, sulphonate, phosphate and phosphonate, suitable for stabilising dispersions of solids in organic liquids and oil/water emulsions, processes for the preparation of the surfactant and dispersions and emulsions containing the surfactant. A preferred species of the surfactant is a poly(hydroxyalkanecarboxylic acid) having the strong acid group attached, either directly or through a linking group, to a terminal hydroxy or carboxylic acid group.
