摘要:
Caustic-free detergent compositions are provided. Detergent compositions including an aminocarboxylate, water conditioning agent, non-caustic source of alkalinity and water beneficially do not require the use of additional surfactants and/or polymers to provide suitable detergency and prevent scale build-up on treated surfaces and enhance protein removal from the treated surfaces. Beneficially the detergent compositions have a concentrate pH less than about 11.5. The detergent compositions are used with a sanitizer to employ the low alkaline detergent compositions are particularly suitable for use as low temperature ware wash detergents that beneficially reduce scale build-up. Methods of employing the low alkaline detergent compositions are also provided.

Provided herein is a composition that includes: (i) chelator (e.g., ethylenediaminetetraacetic acid (EDTA)), (ii) buffer system (e.g., potassium phosphate dibasic and sodium hydroxide), (iii) cleaner (e.g., diethyl glycol monoethyl ether), (iv) solubilizer (e.g., propylene glycol), and (v) diluent (e.g., water), wherein the composition has a pH of at least about 9.5. Also provided is a method of cleaning a medical device that includes contacting the medical device with the composition described herein, for a period of time effective to clean the medical device. Subsequent to the cleaning, the medical device can optionally be disinfected, dried, and stored.
摘要:
Compositions and methods useful for the removal of organic substances from substrates, for example, electronic device substrates, are provided. A method is presented which uses a minimum amount of solid form concentrate that is diluted into water, introduced into a manufacturing tool and heated, applied to said substrate for a sufficient time to allow penetration and removal of an organic substance, and immediately rinsed with water to achieve complete removal. These compositions and methods are particularly suitable for removing and completely dissolving photoresists of the positive variety most commonly used in the manufacture of a flat panel display (FPD) and other electronic substrates.

摘要:
Source water is treated by mixing a first component selected from the group comprising neutralized phosphonic acid compounds, neutralized phosphonate compounds, neutralized derivatives of phosphorus, neutralized anti-scalent polymers, and mixtures thereof, a second component from the group comprising chlorite salt and chlorate salt is admixed to the mixture of the water and the first component, and water. The water and the first and second components are present in amounts sufficient to form a stable liquid composition in which there is substantially no conversion of the second component to chlorine dioxide.

Gel comprising reactive oxidant release agent The invention provides a gel composition comprising 5% to 75% w/w of an inorganic gelling agent other than silica based gelling agents, 0.5-60% w/w, preferably 0.5 to 30% w/w, of an inorganic oxidant release agent and at least 20% w/w of water, and possibly a stabilizer. It further provides a process for making same, comprising preparing a first solution of a dibasic phosphate salt in water comprising dissolved oxidant release agent, preparing a second and solution of a alkaline earth metal salt in water comprising dissolved oxidant release agent, and mixing both, first and second solutions, in a ratio of 1 to 1 to 10 to 1, followed by a concentration step. The gel composition of the invention is suitable for soil, sediment groundwater or water remediation purposes and disinfection or wound healing purposes.
摘要:
A cleaning, disinfection, and indicator agent comprising a water-soluble permanganate, particularly for mixture with an agent for ensuring an alkaline milieu having a pH value of at least 11, which, in addition to the water-soluble permanganate, contains a further oxidizing agent, whose oxidation potential is above that of manganese VII to manganese VI, pH buffer substances, preferably primary and/or secondary alkali carbonates such as sodium carbonate and/or sodium hydrogen carbonate, as well as oxidation-resistant polyphosphates. Furthermore, methods for cleaning, disinfecting, and monitoring the cleanliness of commercial and industrial plants or plant components and the use of an agent according to the present invention as an indicator solution for ascertaining the cleanliness of commercial and industrial plants or plant components by ascertaining the intensity of the light emitted in the violet wavelength range by the solution are described.
摘要:
Methods, compositions and kits for masking and subsequent removal of oil, grease, rust and other stains from a variety of rough solid surfaces, including, but not limited to stone, concrete, asphalt, stucco brick, and ceramic. The methods include coating the stains with an opaque or translucent thin film of a composition that makes the stain practically indistinguishable against the background, exposing the coated stain to the elements, such as, sunlight, air, moisture, resulting in spontaneous transformation, degradation and subsequent removal of the stains from the solid surfaces. The compositions include a photocatalyst by itself or the photocatalyst combined with at least one of, a sensitizer, a dopant, a mediator, a co-reagent, a pigment and a binder. The role of a photocatalyst is to produce highly reactive species or radicals and initiate the degradation of a stain upon exposure to elements, such as, sunlight, air and ambient humidity. Artificial light sources can be used instead of sunlight.
