1. Liquid cleaning compositions comprising:

  • a) as part of the surfactant system, from about 0.1% to about 50% by weight of at least one mid-chain branched surfactant substantially free from geminally-substituted branching selected from the group consisting of surfactants having the formula;

    ##STR56## wherein;

    (i) one or more C1 -C3 alkyl moieties branch from the longest linear carbon chain at one or more positions encompassed by the indicated branching range; and

    (ii) B is a hydrophilic moiety selected from sulfates and alkoxylated sulfates;

    wherein further for this surfactant mixture the average total number of carbon atoms in the branched primary alkyl moieties having the above formula is within the range of greater than 14.5 to about 17.5;

    b) as the other part of the surfactant system, from about 0.1% to about 50% by weight of one or more co-surfactants;

    c) from about 1% to about 99.7% by weight of solvent; and

    d) from about 0.1% to about 75% by weight of liquid cleaning composition adjunct ingredients.
