Abstract
The invention relates to alkyl aryl sulfonate concentrate compositions and provides a process wherein an aqueous solution containing at least 10% by weight of a neutralizing agent is mixed with at least one C.sub.2-9 saturated alcohol and with a C.sub.8-18 alkyl aryl (xylene or toluene) sulfonic acid, the relative quantities of the components being such that the resulting neutralized mixture contains 5 to 40 parts by weight of the alcohol per 100 parts by weight of alkyl aryl sulfonate salt. The resulting flowable liquid concentrate composition are easily handled materials having application, for instance, in enhanced oil recovery processes.
