Abstract
Suggested are degreasing compositions comprising at least one dialkyl amide according to general formula (1) R1CO—NR2R3 (I) in which R1CO stands for a linear or branched, saturated or unsaturated, aliphatic or aromatic, optionally hydroxysubstituted acyl radical having 2 to 56 carbon atoms, and R2 and R3 represent independently from each other alkyl radicals having 1 to 6 carbon atoms.

-10. (canceled)
A method for degreasing a hard surface, comprising the step of contacting a hard surface with at least one organic solvent selected from the group consisting of dialkyl amides of general formula (1),
- R1CO—NR2R3 (I)
- wherein R1CO represents a linear or branched, saturated or unsaturated, aliphatic or aromatic, optionally hydroxysubstituted acyl group having 2 to 56 carbon atoms, and R2 and R3 independently represent alkyl groups having 1 to 6 carbon atoms;
- wherein the at least one dialkyl amide of formula (I) is present in the organic solvent in an amount effective to provide degreasing efficacy.
