Abstract
Detergent compositions comprising a surfactant system that is either (1) a mixture of zwitterionic detergent surfactant and/or amphoteric (non-zwitterionic) detergent surfactant with nonionic detergent surfactant; or (2) short chain nonionic detergent surfactant; a suds reducing amount of a suds controlling alkoxylated material of the formula: C.sub.n (PO).sub.x (EO).sub.y (PO).sub.z in which C.sub.n is a hydrocarbon group containing n carbon atoms, n is a number from about 6 to about 12, x is a number from about 1 to about 6, y is a number from about 4 to about 15, and z is a number from about 4 to about 25; optional, but preferred, hydrophobic cleaning solvent; and polycarboxylate, especially dicarboxylate, detergent builder, provide superior cleaning of all of the soils commonly found in the bathroom while maintaining a desirable low suds profile and good rinsing properties. The compositions have a pH of from about 1 to about 5.5, preferably from about 2 to about 4 when the dicarboxylate builder is used. The compositions are in the form of aqueous liquids.
