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:10-50% by weight of a stable, self-dispersing polyalkoxylated amine having the general structural formula ##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 about 2 to 7 moles of alkoxylated units such that R.sup.3 and R.sup.4 are not both H and R.sup.3 and R.sup.4 combined include from about 2 to 7 moles of alkoxylated units said composition including mixtures of the polyalkoxylated amines; and90-50% by weight of a water-soluble nonionic surfactant selected from the group consisting of ethoxylated alcohols having about 6-8 moles of ethyleneoxy units per mole of alcohol, alkoxylated glycosides having about 10-16 carbon atoms and mixtures thereof; 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.
