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.

An alcohol free, low viscosity, and high-water content air freshener composition is provided. The transparent microemulsion system is stable at a broad range of temperatures. The main ingredient of the composition is water. The composition is free of conventionally-used amphiphilic surfactants including ionic and non-ionic surfactants. The composition contains an oil phase, an aqueous phase and at least one glycol ether solvent. The system is compatible for a wide scope of water-immiscible ingredients that are used in fragrances and flavors.

A method is provided for removing a residue from a surface. The method includes steps of applying a cleaning medium to the surface containing the residue. The cleaning medium comprises up to 100 wt. % of at least a solvent. Allowing the cleaning medium to be in contact with the residue for at least 5 seconds to swell/dissolve the residue for removing the residue from the surface. At least 50 wt. % of the residue and the cleaning medium are removed from the surface by wiping the surface with a shear force. The residue contains a sulfonated polymer having an ion exchange capacity (IEC) of greater than 0.5 meq/g. The sulfonated polymer can kill >90% of microbes coming in contact with the sulfonated polymer in less than 30 min.

The present invention relates to compositions such as cleaning compositions comprising enzymes. The invention further relates, use of compositions comprising such enzymes in cleaning processes.

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.

Provided is a composition which has an excellent affinity with the surface of an adhesive agent and can achieve a high etching rate. The composition according to one embodiment comprises: a quaternary alkylammonium fluoride or a hydrate of a quaternary alkylammonium fluoride; and, as an aprotic solvent, (A) an N-substituted amide compound having no active hydrogen on a nitrogen atom, and (B) a dipropylene glycol dimethyl ether, wherein (B) the dipropylene glycol dimethyl ether has the percentage of a structural isomer represented by formula (1) of at least 50 mass % with respect to the total amount of (B) the dipropylene glycol dimethyl ether. ##STR00001##
