##STR46## 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;

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.

2. The liquid cleaning composition according to claim 1 wherein the surfactant system comprises the mid-chain branched surfactant at levels of from about 1% to about 40% by weight of the surfactant system.
