Abstract
Abstract Compositions are provided which contain isopropylamine salts of a mixture of linear alkylbenzene sulfonic acids in which the alkyl groups contain 7 through 14 carbon atoms, a predominant amount of the mixture containing from 11 through 12 carbon atoms, from about 19 to about 24 numerical percent of linear alkylbenzene sulfonic acid salts having the benzene sulfonic acid group located on the two position of the alkyl group and an organic solvent which is preferably Stoddard Solvent or 1,1,2trichloro-1,2,2-trifluoroethane or trichloromonofluoromethane. Such compositions have a high tolerance for water even in the presence of inorganic salts and are useful for solvent cleaning of textiles and machinery.
