Abstract
A light duty liquid cleaning composition comprising at least one ammonium or metal salt of a C8-C16 linear alkyl benzene sulfonate surfactant, at least one ammonium or metal salt of an ethoxylated C8-C18 alkyl ether sulfate surfactant having 1 to 30 moles of ethylene oxide, and at least one betaine surfactant; wherein (a) a total amount of surfactant in the composition is at least 30 weight %, (b) the composition has a pH less than 7 and a viscosity of less than 75 cPs measured at 25° C., (c) if a magnesium salt of a C8-C16 linear alkyl benzene sulfonate surfactant is present in the composition, it is present in an amount of 0.1 to less than 3 or greater than 16% by weight of the composition, and (d) the composition does not contain an inorganic magnesium salt.
