Acidic liquid detergent compositions for bathrooms

An acidic aqueous hard surface detergent composition comprising:

• (a) a detergent surfactant system which comprises (1) a mixture of from about 0.01% to about 8% of (i) zwitterionic detergent surfactant having the generic formula R--N.sup.(+) (R.sup.2)(R.sup.3)R.sup.4 X.sup.(-) wherein R is a hydrophobic group;
• R.sup.2 and R.sup.3 are each C.sub.1-4 alkyl, hydroxyl alkyl or other substituted alkyl group which can also be joined to form ring structures with the N:
• R.sup.4 is a moiety joining the cationic nitrogen atom to the hydrophilic group and is an alkylene, hydroxyl alkylene or polyalkoxy group containing from about 1 to about 4 carbon atoms:
• and X is the hydrophilic group which is a carboxylate or sulfonate group for the zwitterionic detergent surfactant with (ii) from about 0.01% to about 6% of nonionic detergent surfactant which contains a C.sub.7-22 alkyl group and from about 2.5 to about 12 ethylene oxide groups to give an HLB of from about 8 to about 16;
• (b) at least a suds reducing amount and less than about 5% 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, (c) optionally, from about 1% to about 15% of hydrophobic solvent that provides a primary-cleaning function;
• and (d) from about 2% to about 14% of polycarboxylate detergent builder, and said composition having a pH of from about 1 to about 5.5.
