ABSTRACT:
An improved aqueous anionic surfactant system for providing low interfacial tensions against oil is formed by including an aromatic ether polysulfonate in the system. This improves the tolerance of the system toward salts of monovalent and/or multivalent cations, and also causes emulsions formed between the oil and the oil-displacing system to be less viscous and less stable.
