Abstract
Abstract Nonsoap synthetic detergent bars consisting essentially of olefin sulfonates in which the hydrocarbon portions contain from 8 to 20 carbon atoms and have an average molecular weight of from 165 to 200, the sulfonates being salts of water-soluble saltforming cations, at least 80 mol percent of the salts being calcium olefin sulfonates.
