Abstract

A liquid detergent composition may comprise a first surfactant that is a mixture of surfactant isomers of Formula 1 and a surfactant of Formula 2, where about 50% to about 100% by weight of the first surfactant is the isomer having m+n=11, about 25% to about 50% of the mixture of surfactant isomers of Formula 1 have n=0, and about 0.001% to about 25% by weight of the first surfactant is a surfactant of Formula 2, where X is a hydrophilic moiety, and a second surfactant that comprises a nonionic ethoxylated alcohol.
