Cleaning solution composition
Provided is a cleaning solution composition which, when cleaning the surface of a semiconductor substrate or glass substrate, does not damage SiO.sub.2, Si.sub.3N.sub.4, Si, and the like forming a layer on the substrate surface, can be used under processing conditions applicable to a brush scrub cleaning chamber equipped with a CMP apparatus, and can efficiently remove compounds derived from abrasive particles in a slurry. This cleaning solution composition for cleaning the surface of a semiconductor substrate or glass substrate contains: one or two or more fluorine atom-containing inorganic acids or salts thereof; water; one or two or more reducing agents; and one or two or more anionic surfactants, and has a hydrogen ion concentration (pH) of less than 7.
AQUEOUS CLEANING COMPOSITIONS AND THE USE THEREOF
The present invention broadly relates to aqueous cleaning compositions and the use thereof in cleaning soiled surfaces.
Post CMP cleaning composition
The disclosure generally relates to a composition and process for cleaning residue and/or contaminants from microelectronic devices having said residue and contaminants thereon. The residue may include post-CMP, post-etch, and/or post-ash residue. The compositions and methods are particularly advantageous when cleaning a microelectronic surface comprising copper, low-k dielectric materials, and barrier materials comprising at least one of tantalum-containing material, cobalt-containing material, tantalum-containing, tungsten-containing, and ruthenium-containing material.
Solvent compositions for removing petroleum residue from a substrate and methods of use thereof
A method of cleaning highway and road construction equipment is disclosed.
Methods of facilitating removal of a fingerprint
Bioactive coatings that include a base and a protein associated with the base for actively promoting the removal of organic stains are provided. In aspects, bioactive coatings that are stabilized against inactivation by weathering are provided including a base associated with a chemically modified enzyme, and, optionally a first polyoxyethylene present in the base and independent of the enzyme. The coatings are optionally overlayered onto a substrate to form an active coating facilitating the removal of organic stains or organic material from food, insects, or the environment.

HIGH FLASHPOINT ALCOHOL BASED CLEANING, SANITIZING AND DISINFECTING COMPOSITION AND METHOD OF USE ON FOOD CONTACT SURFACES
The invention is directed to a high flashpoint alcohol based cleaning, sanitizing and disinfecting composition and its method of use on food contact surfaces. More particularly, the present invention relates to a quick drying and ready to use cleaning and sanitizing formula with an isopropyl alcohol level low enough to permit a reduced flammability rating while maintaining microbiological sanitizing and disinfecting properties.
AMBIENT MOISTURE-ACTIVATED HARD SURFACE TREATMENT POWDER
Ambient moisture-activatable surface treatment powders containing persalt, positively charged phase transfer agent and alkaline pH buffering may be activatable without the addition of liquid. Some ambient moisture-activatable surface treatment powders are substantially free of bleach activators and/or chlorine. Methods of use of ambient moisture activatable powders include applying them to the surfaces to be treated.
Liquid detergent composition
There is provided a liquid detergent composition comprising an internal olefin sulfonate salt at a high concentration and being excellent in stability at low temperatures without lowering the detergency. The liquid detergent composition comprises the following components (A) to (D), wherein a mass ratio of the component (A) to a total amount of the component (B) and the component (C), (A/(B+C)), is 0.6 or more and 5 or less; and a mass ratio of the component (B) to the component (C), (B/C), is 0.05 or more and 1.8 or less. (A): 10 to 40% by mass of an internal olefin sulfonate salt having 16 to 18 carbon atoms in which a content of an internal olefin sulfonate salt having a sulfonic group at the C-2 position is 5% by mass to 25% by mass; (B): 0.5 to 16% by mass of a fatty acid salt represented by the following formula (1): R.sup.1COOM (1) wherein R.sup.1 represents an alkyl group or alkenyl group having 10 or more and 14 or less carbon atoms; and M represents a hydrogen atom, an alkali metal, alkaline earth metal ( atom), ammonium or an organic ammonium; (C): an organic solvent having one or more hydroxyl groups; and (D) water.
Use of an alcohol hybrid to modify the rheology of polyethoxylated alcohol sulfates
In one embodiment, a polyethoxylated alcohol sulfate composition is provided which includes a polyethoxylated alcohol sulfate, such as sodium laureth ether sulfate (SLES), water, a mono-alcohol, and a polyol. The two alcohols form a synergistic blend, enabling a significant reduction of the viscosity of the polyethoxylated alcohol sulfate composition. Also provided is an embodiment of a method for modifying the rheology of polyethoxylated alcohol sulfate by use of a mono-alcohol and a polyol simultaneously. Finally provided is an embodiment of a detergent composition which is prepared by use of the polyethoxylated alcohol sulfate composition described herein, in addition to other commonly known ingredients.
