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).sub.a (M.sup.q+).sub.b wherein D is
SO.sub.3 --, 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.degree. 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.
