ABSTRACT "Surfactants" For use as surfactants in oil/water systems, e.g., hydraulic fluids, compounds are described which contain in the molecule a hydrophobic component and a hydrophilic component covalently bonded together, where the hydrophobic component is a saturated or unsaturated C30-500 hydrocarbon chain and the hydrophilic component contains an anionic grouping selected from phosphate, phosphonate, sulphate, sulphonate and carboxymethyl. |
