A detergent composition comprising an enzyme and a bleaching compound and comprising two or more distinct regions, wherein the enzyme is located in a first distinct region and the bleaching compound is located in a second distinct region and further wherein a builder comprising an amino acid based compound and/or succinate based compound is located in the first distinct region. The compositions exhibit improved stability of the enzyme.

Liquid compositions include: a) one or more anionic surfactants and b) one or more nonionic surfactants,
wherein they comprise the surfactants of components a) and b) in a total concentration of >25% by weight, based on the total weight of the liquid composition, and are free from alkanolamines and salts thereof. Upon combination with bleaches, the liquid compositions exhibit a significantly higher bleaching efficacy than comparable alkanolamine-containing compositions.

This invention provides a liquid composition that removes titanium nitride from a substrate without corroding tungsten or a low-k interlayer dielectric also present on said substrate. Said liquid composition has a pH between 0 and 4, inclusive, and contains the following: at least one oxidizing agent (A) selected from the group consisting of potassium permanganate, ammonium peroxodisulfate, potassium peroxodisulfate, and sodium peroxodisulfate; a fluorine compound (B); and a tungsten-corrosion preventer (C). The tungsten-corrosion preventer (C) either contains at least two different compounds selected from a group of compounds (C1) consisting of alkylamines, salts thereof, fluoroalkylamines, salts thereof, and the like or contains at least one compound selected from said group of compounds (C1) and at least one compound selected from a group of compounds (C2) consisting of polyoxyalkylene alkylamines, polyoxyalkylene fluoroalkylamines, and the like. The mass concentration of potassium permanganate in the abovementioned oxidizing agent (A) is between 0.001% and 0.1%, inclusive, and the mass concentration of the abovementioned fluorine compound (B) is between 0.01% and 1%, inclusive.

The invention relates to a solid composition for use in the treatment of textiles, containing respectively with respect to the total weight of the solid composition, a respective total amount of 25-65 wt.-% of at least one peroxide compound, 10-20 wt.-% of at least one organic bleaching activator, 5-20 wt.-% alkali metal silicate, 1-15 wt.-% of at least one polysaccharide, 0-5 wt.-% surfactant. Said solid composition is enveloped in a water-soluble material in order to obtain storage-stable single use portions together with liquid surfactant-containing compositions. The claimed solid composition can be used as an additive in conventional textile treatment agents.

Solid compositions for use in textile treatment, each comprising, based on the total weight of the solid composition, a total amount of each of —30% to 70% by weight of at least one peroxide compound, —10% to 20% by weight of at least one organic bleach activator, —5% to 50% by weight of hydrogencarbonate, calculated as sodium hydrogencarbonate, —0% to 5% by weight of surfactant, where the total amount of organic compound in the solid composition is 10% to 50% by weight, preferably 20% to 35% by weight, are thermally stable and can be stored reliably. They are suitable as an additive to conventional textile treatment compositions, especially to liquid washing compositions, and can be provided as a portion encased with a water-soluble material.

Effervescent compositions are disclosed, particularly effervescent compositions useful in toilet bowls. The effervescent composition may include at least one liquid or solid hydrogen peroxide source and at least one catalyst capable of catalyzing an oxidation of the hydrogen peroxide source in the presence of a liquid, such as water. Accordingly, the effervescent composition is capable of effervescence in the presence of a liquid. The effervescent composition may also include a non-hygroscopic solvent. The presence of the non-hygroscopic solvent may assist the effervescent composition in substantially avoiding effervescence until the composition contacts the liquid. Optionally, the ratio of the hydrogen peroxide source and catalyst to the non-hygroscopic solvent is not less than 9:1.

The present invention relates to compositions for the photodynamic control of micro-organisms wherein the compositions comprise a photosensitiser which comprises a dyestuff and produces singlet oxygen when irradiated by means of light for the disinfection and sterilization of materials, commodities and surfaces contaminated with one or more species of micro-organisms including bacteria, fungi, algae, yeasts, bacterial spores and fungal spores.

A cleaning compound for cleaning surfaces that includes at least one container, with each container including a peroxide and/or an alkaline reactant therein. The alkaline reactant is selected to raise the pH of the cleaning compound into the alkaline range when the peroxide and the alkaline reactant are mixed together. The cleaning compound may be a liquid or dry compound, which is applied to the surface to be cleaned.

Container comprising a single unit dose of a detergent composition containing at least one complexing agent (A) dissolved in an aqueous medium, said complexing agent (A) being a mixture of the L-and D-enantiomers of methyl glycine diacetic acid (MGDA) or its respective mono-, di- or trialkali metal or mono-, di- or triammonium salts, said mixture containing predominantly the respective L-isomer with an enantiomeric excess (ee) in the range of from 5 to 85%, wherein said container is made from a polymer.

The present invention relates to a detergent composition comprising alkali metal carbonate, a chelant selected from the group consisting of MGDA, alkali metal tripolyphosphate, GLDA, and mixtures thereof, alkali metal percarbonate, and a peroxidation catalyst, wherein the molar ratio of chelant to alkali metal percarbonate is in the range of 1.8 to 3.4. The detergent composition is particularly suited for the removal of tea and coffee stains.
