1. A liquid hand dishwashing cleaning composition comprising from about 8% to about 45% by weight of the total composition of a surfactant system, wherein the surfactant system comprises at least about 40% by weight of the surfactant system of anionic surfactant, wherein the anionic surfactant comprises at least about 50% by weight of the anionic surfactant of alkyl sulfate anionic surfactant, wherein:
the alkyl sulfate anionic surfactant comprises a mixture of linear and branched alkyl sulfate anionic surfactant with an average degree of branching of more than about 10%, wherein:
the branched alkyl sulfate anionic surfactant comprises C2-branched alkyl sulfate anionic surfactant and non-C2-branched alkyl sulfate anionic surfactant, wherein the weight ratio of non-C2-branched alkyl sulfate anionic surfactant to C2-branched alkyl sulfate anionic surfactant is from about 2.0:1 to 5:1;
the alkyl sulfate anionic surfactant has an alkyl chain comprising an average of from 12 to 13 carbon atoms; and
the alkyl sulfate anionic surfactant is free of alkoxylation; and
the non-C2 branched alkyl sulfate anionic surfactant comprises less than about 10% by weight of the non-C2 branched alkyl sulfate anionic surfactant of C1-branched alkyl sulfate anionic surfactant.
