Abstract
The present invention relates to an emulsifier composition suitable for mixing with oil to form lubricants comprising at least one non-extracted salt of a natural petroleum sulfonic acid having about 15 wt-% to about 30 wt-% active content; at least one branched chain alkylaryl sulfonic acid or salt thereof; at least one linear alkylaryl sulfonic acid or salt thereof; and optionally at least one other sulfonic acid or salt thereof for adjusting the average equivalent equivalent weight of the resultant emulsifier composition.
