The sulfonates have general formulas of (I) and (II) where R and Z are independently selected from the group consisting of nonionic or anionic, substituted or unsubstituted C1-C30 straight, branched or cyclic alkyl, alkenyl, alkynyl, alkylaryl or aryl group; Y is a radical that, upon hydrolysis of the sulfonate, forms an alcohol with a boiling point at 760 mm Hg of less than about 300 ~C that is a perfume; and excluding geranyl and neryl methanesulfonates. Preferably these sulfonate compounds are incorporated into laundry and cleaning compositions.
