- 2. The method of claim 2 wherein the alkoxylated units are selected from the group consisting of ethyleneoxy, propyleneoxy, butyleneoxy and mixtures thereof.
- 3. The method of claim 1 wherein R3 and R4 combined include from about 2 to 5 moles of alkoxylated units.
- 4. The method of claim 1 wherein the polyalkoxylated amine component is present in the amount of from about 15-85% by weight of the composition and the water-soluble surfactant amine oxide component is present in the amount of from about 85-15% by weight of the composition.
- 5. The method of claim 1 wherein the at least one amine oxide is selected from the group consisting of poly (5) oxypropylene isodecyloxypropylamine oxide, bis-(2-hydroxyethyl)isodecyloxypropylamine oxide and mixtures thereof.
- 6. The method of claim 1 wherein the detergent composition further includes from about 0.01-90% by weight of at least one builder.
- 7. The method of claim 6 wherein the builder is selected from the group consisting of tetrapotassium pyrophosphate, sodium tripolyphosphate sodium carbonate, sodium metasilicate pentahydrate and potassium silicate.
- 8. The method of claim 1 wherein the detergent composition further includes at least one adjuvant.
- 9. The method of claim 1 further including, at any time, adding less than about 30% by weight of at least one organic solvent to the detergent composition provided that the weight percent of the organic solvent is less than about 10% of the diluted composition when applied to the object to be cleaned.
- 10. A method for cleaning hydrocarbon-containing soils from a surface with an aqueous cleaning composition comprising the steps of:preparing a detergent composition comprising: from 0.5-99% by weight of at least one polyalkoxylated amine having the general structural formula: wherein R1 is selected from an alkyl, aryl or alkylaryl group having between 6 and 22 carbon atoms, R2 is from 0 to 7 moles of alkoxylated units; n is 0 or 1 and R3 and R4 are each selected from H and from 1 to 5 moles of alkoxylated units such that R3 and R4 are not both H and R3 and R4 combined include about 7 or fewer moles of alkoxylated units; from 99-0.5% by weight of a nonionic water-soluble surfactant selected from the group consisting of alkoxylated alkyl phenols, alkoxylated alcohols, alkoxylated glycosides and mixtures thereof; and from 99-0.5% by weight of at least one quaternary ammonium compound component having the general structural formula: wherein R9 is selected from an allyl, alkylamidopropyl, hydroxyalkyl, aryl or alkylaryl group having between 6 and 22 carbon atoms, R10 is from 0 to 7 moles of alkoxylated units, n is 0 or 1, R11 and R12 are each selected from the group consisting of 1 to 8 moles of alkoxylated units, a C1-5 alkyl group, hydroxyalkyl and an organic group having between 6-26 atoms, R13 is a methyl group or ethyl group and —X— is a halide or sulfate group; and at any time before cleaning, adding from about 90 to 99.99% by weight of water to the composition; and applying the detergent composition to the object to be cleaned.
- 11. The method of claim 10 wherein the alkoxylated units are selected from the group consisting of ethyleneoxy, propyleneoxy, butyleneoxy and mixtures thereof.
- 12. The method of claim 10 wherein R3 and R4 combined include from about 2 to 5 moles of alkoxylated units.
- 13. The method of claim 10 wherein R11 and R12 combined include from about 2 to 10 moles of alkoxylated units.
- 14. The method of claim 10 wherein the polyalkoxylated amine is present in the amount of from about 10-40% by weight of the composition, the nonionic water-soluble surfactant is present in the amount of from about 20-80% by weight of the composition and the quaternary ammonium compound is present in the amount of from about 10-40% by weight of the composition.
- 15. The method of claim 10 wherein the alkoxylated alkyl phenols are selected from the group consisting of nonylphenol 9 mole ethoxylate and octylphenol 9 mole ethoxylate and mixtures thereof.
- 16. The method of claim 10 wherein the at least one quaternary ammonium compound component is selected from the group consisting of bis-(2-hydroxyethyl) isodecyloxypropyl methyl ammonium chloride, dodecyl trimethyl ammonium chloride, isodecyloxypropyl dihydroxyethyl-methylammonium chloride and mixtures thereof.
- 17. The method of claim 10 wherein the detergent composition further includes from about 0.01-90% by weight of at least one builder.
- 18. The method of claim 17 wherein the builder is selected from the group consisting of tetrapotassium pyrophosphate, sodium tripolyphosphate sodium carbonate, sodium metasilicate pentahydrate and potassium silicate.
- 19. The method of claim 10 wherein the detergent composition further includes at least one adjuvant.
- 20. The method of claim 1 further including, at any time, adding less than about 30% by weight of at least one organic solvent to the detergent composition provided that the weight percent of the organic solvent is less than about 10% of the diluted composition when applied to the object to be cleaned.
- 21. The method of claim 1 wherein R7 and R8 combined include from about 2 to 7 moles of alkoxylated units.
