(in formula (1), R.sup.101 represents a C1 to C6 alkyl group; and R.sup.102 represents a C1 to C6 alkylene group.)

A cleaning agent composition for use in removal of an adhesive residue, the composition containing a quaternary ammonium salt and a solvent, wherein the solvent consists of an organic solvent, and the organic solvent includes an N,N,N′,N′-tetra(hydrocarbyl)urea.

A laundry composition according to the present disclosure includes a solvent selected from the group consisting of solketal and derivatives thereof and a fragrance, wherein the fragrance has a log P value of −1.0 to 4.5, and a washing machine includes a washing unit configured to receive a solvent to wash accommodated fibers; a steam collector configured to condense a gaseous phase discharged from the washing unit and supply the same to a solvent collector; and the solvent collector configured to collect a liquid phase discharged from the washing unit and supply the solvent to a solvent supplier, wherein the solvent collector includes a filter unit configured to remove foreign substances from the solvent supplied from at least one of the steam collector and the washing unit; and a solvent storage configured to store the solvent supplied from the filter unit.

The present invention relates to compounds which form, under perhydrolysis conditions, certain cationic organic peracids, to the use of said compounds for activating peroxygen compounds in the context of bleaching stains when washing textiles and cleaning hard surfaces, and to washing and cleaning agents that contain said compounds.

A composition suitable for cleaning hard surfaces comprising a natural oil solvent and a natural oil thickener is provided.

Compositions and methods for cleaning surfaces, such as for removing residues or other coatings from molds and other industrial parts, such compositions comprising, for example, a first solvent comprising a pyrrolidone such as 2-pyrrolidone, 1-(2-hydroxyethyl)-2-pyrrolidone, or mixture thereof; and a second solvent selected from the group consisting of an imidazole (such as 1,2-dimethylimidizole), an alkylene glycol ether (such as ethylene glycol monobutyl ether or diethylene glycol monobutyl ether, a terpene (such as d-limonene), and mixtures thereof. In various embodiments, such methods are for removing residues from molds used in forming polyurethane parts, wherein residues comprise polyurethane, urethane reactants, and mold release agents. The compositions may be substantially free of 1-methyl-2-pyrrolidone and of 1-ethyl-2-pyrrolidone.
