    摘要： A hand dishwashing compositions comprising; a) about 0.1% to about 99.9% by weight of said composition of an alkylarylsulfonate surfactant system comprising from about 10% to about 100% by weight of said surfactant system of two or more crystallinity-disrupted alkylarylsulfonate surfactants of formula (B—Ar—D)a(Mq+)b wherein D is SO3—, M is a cation or cation mixture, q is the valence of said cation, a and b are numbers selected such that said composition is electroneutral; Ar is selected from benzene, toluene, and combinations thereof; and B comprises the sum of at least one primary hydrocarbyl moiety containing from 5 to 20 carbon atoms and one or more crystallinity-disrupting moieties, wherein said crystallinity-disrupting moieties interrupt or branch from said hydrocarbyl moiety; and wherein said alkylarylsulfonate surfactant system has crystallinity disruption to the extent that its Sodium Critical Solubility Temperature, as measured by the CST Test, is no more than about 40° C.; and wherein further said alkylarylsulfonate surfactant system has at least one of the following properties: percentage biodegradation, as measured by the modified SCAS test, that exceeds tetrapropylene benzene sulfonate; and weight ratio of nonquaternary to quaternary carbon atoms in B of at least about 5:1; and b) from about 0.00001% to about 99.9% by weight of said composition of a conventional hand dishwashing adjunct; c) from about 0.01% to about 7% by weight of composition of a divalent ion selected from the group consisting of magnesium, calcium and mixtures thereof.
