Conclusions It was observed that sulphonated castor oil (with 28% water content) is miscible with much greater volumes of aromatic solvents than with solvents of the paraffinic type. Separation of the mixture at high dilution ratios shows that it is likely that a miscellar structure exists between the solvent, the sulphonated oil, and the water contained in the sulphonated oil. This miscellar structure is disrupted at higher dilution ratios. Furthermore it was generally observed that mixtures where the sulphonated oil was completely dissolved in the solvent gave stable milky white emulsions on dilution with water. The latter fact is of great practical importance.
