[Problem] To provide a cosmetic brush cleaner excellent in quick dryability and capable of removing stains such as deposited cosmetics with ease in the following manner: impregnating tissue paper, towel, or the like with the cleaner to wipe off the cosmetics, sebum, and the like deposited on a cosmetic brush; or directly spraying the cleaner on a cosmetic brush, and wiping the brush with dry tissue paper or the like. [Solution] A cosmetic brush cleaner including: (A) a lower alcohol in an amount of 30 to 99 mass %; (B) a volatile oil in an amount of 1 to 70 mass %; and (C) water in an amount of 7 mass % or less (including 0 mass %).

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.

The present invention is drawn to a wash that will effectively clean printing related equipment such as a printing press, including all of its components, of materials used in the printing process, including printing inks, paper, and fountain solutions.

A cleaning liquid composition is provided. More particularly, a cleaning liquid composition includes a transition metal compound represented by Chemical Formula 1 (see the detailed description of the present invention); and a hydrocarbon-based solvent, and a cleaning method of a polymerization apparatus using the same.

A sensor array includes a plurality of sensors. A sensor of the plurality of sensors has a sensor pad exposed at a surface of the sensor array. A method of treating the sensor array includes exposing at least the sensor pad to a wash solution including sulfonic acid and an organic solvent and rinsing the wash solution from the sensor pad.

An automotive surface is cleaned by applying an effective amount of a cleaning composition comprising a) at least one hydrocarbon solvent in an amount from about 3 weight percent to about 20 weight percent of the composition, b) at least one thickener/rheology modifier in an amount from about 0.01 weight percent to about 3 weight percent, c) at least one silicone fluid has a viscosity ranging from about 500 to about 20,000 centistokes at 25 C., present in an amount from about 0.1 weight percent to about 3 weight percent, d) at least one wetting agent in an amount from about 0.001 to about 2%, e) at least one hydrophobic additive in an amount from about 0.1 to about 3%, and f) water in an amount from about 60 weight percent to about 85 weight percent to the automotive surface with an application implement.

A cleaning composition, which is suitable for cleaning fuel delivery systems, air-intake systems, intake valves, and combustion chambers, includes at least 3 wt. % of a polyether component, at least 5 wt. % of a polar solvent, and at least 5 wt. % a non-polar solvent. The polyether component is selected from polyethers, polyetheramines, and mixtures thereof.

A method for cleaning and coating a tip of a test probe in an integrated circuit package test system is provided. The method includes 1) saturating a brush tip comprising nonporous bristles with a solution of phosphonic acid; 2) applying the solution of phosphonic acid to the tip of the test probe with the brush tip to coat the tip of the test probe with the solution of phosphonic acid; and 3) allowing the solution of phosphonic acid to dry on the tip of the test probe and form a self-assembled monolayer of phosphonates thereon.

The present invention relates to wash oil for use as an antifouling agent in gas compressors, in particular in cracked gas compressors, including at least one compound according to formulae (II) ##STR00001## with the moieties R.sup.2 and R.sup.3 are selected from a group of linear or branched C.sub.1-C.sub.20-alkyl, C.sub.3-C.sub.10-cycloalkyl and linear or branched C.sub.1-C.sub.10-alkyl substituted C.sub.3-C.sub.10-cycloalkyl and C.sub.6-C.sub.12 aryl and C.sub.1-C.sub.10-alkyl substituted C.sub.6-C.sub.12 aryl. The moieties can be interrupted by oxygen or nitrogen. The moieties can be functionalised with hydroxyl groups or amino groups. The moieties can be the same or different. The invention relates also to the use of such wash oil as anti-fouling agent.

A gun oil composition adapted specifically for the needs and requirements of modern firearms. The gun oil composition improves lubricity and gun performance under normal and extreme heat and pressure, minimizes and largely prevents the build-up of carbon and debris fouling on metal and non-metal components of the firearm, and substantially reduces cleaning time, while providing increased protection against environmental components such as dust, dirt and rust. The gun oil composition can include a base oil having at least a high viscosity index, an oil having at least a medium viscosity index with a detergent additive, a low viscosity penetrating oil, and a sulfurized ester.
