Abstract:
A method for removing hydrocarbon-containing greases and oils from fabric in a laundry washing process comprising the steps of:preparing a concentrated detergent composition consisting essentially of:about 10-40% by weight of a stable, self-dispersing polyalkoxylated amine having a general structural formula selected from the group consisting of: ##STR5## wherein R.sup.1 is selected from an alkyl, aryl or alkylaryl group having between 6 and 22 carbon atoms;R.sup.2 is from 0 to 7 moles of alkoxylated units;n is 0 or 1,R.sup.3 and R.sup.4 are each selected from H and from 1 to 15 moles of alkoxylated units such that R.sup.3 and R.sup.4 are not both H; and ##STR6## wherein R.sup.5 is selected from an alkyl, aryl or alkylaryl group having between 6 and 22 carbon atoms;R.sup.6 is from 0 to 7 moles of alkoxylated units;n is 0 or 1;R.sup.7, R.sup.8 and R.sup.9 are each selected from H and from 1 to 15 moles of alkoxylated units such that R.sup.7, R.sup.8 and R.sup.9 are not each H and mixtures thereof; andabout 90-60% by weight of at least one alkoxylated alky pheno water-soluble nonionic surfactant andwashing the fabric to be cleaned with the detergent composition in a laundering process wherein the fabric is immersed in water, the water having a pH of about between 6.5-10 and a temperature of about 28.degree. C. to about 75.degree. C., and the fabric is agitated for a period of time to remove the hydrocarbon-containing greases and oils.
