Claims
- 1. The process of cleaning hard surfaces comprising the step of: spraying said surfaces with an acidic aqueous hard surface detergent composition comprising: (a) a detergent surfactant system which comprises: a mixture of amphoteric and nonionic detergent surfactants, said amphoteric detergent surfactant being selected from the group consisting of: C.sub.8-14 amidoalkylene glycinate detergent, cocoyl amido ethyleneamine-N-(hydroxyethyl)-2-hydroxypropyl-1-sulfonate, C.sub.8-10 fatty acyl amidoethyleneamine-N-(methyl)ethyl sulfonate, cocoylamido ethyleneamine-N-(methyl)-acetates, cocoylamidoethyleneamine-N-(hydroxyethyl)-acetates, cocoylamidopropylamine-N-(hydroxyethyl)-acetates, substituted amino propionates, and mixtures thereof including analogs and homologs thereof, as their water-soluble salts, or acids; (b) optional hydrophobic solvent that provides a primary cleaning function; and (c) polycarboxylate detergent builder, said composition having a pH of from about 1 to about 5.5, and from about 2 to about 4 when said polycarboxylate detergent builder comprises dicarboxylate detergent builder.
- 2. The process of cleaning hard surfaces comprising the step of: spraying said surfaces with an acidic aqueous hard surface detergent composition comprising: (a) a mixture of amphoteric-non-zwitterionic and nonionic detergent surfactants, said amphoteric-non-zwitterionic detergent surfactant having an amine group that is protonated below pH 5.5 to form a cationic group instead of a quaternary group and, optionally, a group that is an anionic group below pH 5.5, and said amphoteric detergent surfactant being selected from the group consisting of: C.sub.8-14 amidoalkylene glycinate detergent, cocoyl amido ethyleneamine-N-(hydroxyethyl)-2-hydroxypropyl-1-sulfonate, C.sub.8-10 fatty acyl amidoethyleneamine-N-(methyl)ethyl sulfonate cocoylamido ethyleneamine-N-(methyl)-acetates, cocoylamidoethyleneamine-N-(hydroxyethyl)-acetates, cocoylamidopropylamine-N-(hydroxyethyl)-acetates, substituted amino propionates, and mixtures thereof including analogs and homologs thereof, as their water-soluble salts, or acids, said nonionic detergent surfactant being an alkoxylated alcohol or alkyl phenol having an HLB of from about 6 to about 18, and the ratio of said amphoteric-non-zwitterionic detergent surfactant to said nonionic detergent surfactant being from about 1:4 to about 3:1; (b) optional hydrophobic solvent that provides a primary cleaning function; and (c) polycarboxylate detergent builder, said composition having a pH of from about 1 to about 5.5, and from about 2 to about 4 when said polycarboxylate detergent builder comprises dicarboxylate detergent builder.
- 3. The process of claim 2 wherein said composition contains additional ingredients selected from the group consisting of: hydrophobic solvent selected from the group consisting of: glycol ethers having the formula R.sup.1 --O--(R.sup.2 O)--.sub.m H wherein each R.sup.1 is an alkyl group which contains from about 4 to about 8 carbon atoms, each R.sup.2 is either ethylene or propylene, and m is a number from 1 to about 3 and the compound has a solubility in water of less than about 20%; benzyl alcohol; n-hexanol; phthalic acid esters of C.sub.1-4 alcohols; and mixtures thereof; polycarboxylate detergent builder having the ability to bind calcium under acid conditions; and mixtures thereof.
- 4. The process of claim 2 wherein said amphoteric-non-zwitterionic detergent surfactant has the generic formula:
- RC(O)--N(R.sup.1)--(CH.sub.2)n--N(R.sup.1)--CH.sub.2 --C(O)--OH
- wherein RC(O)-- is a C.sub.8-14 hydrophobic fatty acyl moiety containing from about 8 to about 14 carbon atoms which, in combination with the nitrogen atom, forms an amido group, each n is from 1 to 3, and each R.sup.1 is hydrogen or a C.sub.1-2 alkyl or hydroxyalkyl group.
