Abstract
This invention is directed to an improved method for removing hydrocarbon-containing soils. The invention consists of preparing a detergent composition and applying the composition to the surface to be cleaned. Broadly, the detergent composition consists of from 1 to 99% by weight of at least one polyalkoxylated amine and from 99-1% by weight of at least one water-soluble surfactant. Other constituents may be added to enhance performance. The invention has desirable foamability characteristics.
Claims21
A method for cleaning hydrocarbon-containing soils from a surface with an aqueous cleaning composition comprising the steps of:
- preparing a detergent composition consisting essentially of:
- from 1-99% 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,
- R3 and R4 are each selected from H and from about 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;
- and
- from 99-1% by weight of at least one amine oxide water-soluble surfactant having the general structural formula:
- wherein
- R5 is selected from an alkyl, alkylamidopropyl,
- hydroxyalkyl, aryl or alkylaryl group having between 6 and 22 carbon atoms,
- R6 is from 0 to 7 moles of alkoxylated units,
- n is 0 or 1 and
- R7 and R8 are each selected from the group consisting of 1 to 10 moles of alkoxylated units, a C1-5 alkyl group, hydroxyalkyl and an organic group having between 6-26 atoms;
- 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.
The method of claim 2 wherein the alkoxylated units are selected from the group consisting of ethyleneoxy, propyleneoxy, butyleneoxy and mixtures thereof.
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.
