2121792 9405759 PCTABS00030 This invention is directed to cleaning compositions and methods useful in removing soils, particularly those of oil and grease, from surfaces particularly those of fabric. The composition includes a sulfonated alkylated aromatic surfactant and a nonionic surfactant. The class of sulfonated alkylated aromatic surfactant analogs used in the cleaning composition of the present invention will comprise at least one benzene ring wherein additional benzene rings can be attached in various forms, for example polycyclic aromatic(s) such as naphthalene, anthracene and the like, or via an ether linkage or other linking atoms. The sulfonated alkylated aromatic (SAA) will include at least one sulfonate group; wherein for aromatics consisting of more than one benzene ring, disulfonate is present in less than 50 percent of the total sulfonated alkylated aromatic. The SAA will also contain at least one alkyl group attached to the aromatic moiety of from about C18 up to about C30.
