Home care compositions including a surfactant and an amylase. The amylase includes a recombinant, non-naturally-occurring variant of a parent alpha-amylase, the variant alpha-amylase having at least about 80% identity to SEQ ID NO: 5 and having amino acid substitutions at positions 51 and/or 125 with respect to SEQ ID NO: 5

Stabilized compositions employing a sequestrant system and a binding system for improving shelf stability and dispensing stability of a solid activated bleach composition are disclosed. The compositions contain a peroxygen source and a catalyst activator which require generation of a peroxycarboxylic acid or other active oxygen sanitizing agent at a point of use. Stabilized compositions employ a sequestrant system including a phosphonic acid and/or dipicolinic acid sequestrant and a binding system comprising an anionic surfactant for a solid formulation of a catalyst activator and peroxygen source to provide shelf stability and dispensing stability for a activated bleach composition. Methods of formulating and use are further disclosed.

Provided is a cleaning composition for a component of a semiconductor manufacturing process chamber including: a foaming agent; an oxidizing agent; and an acidic compound, in which a value of (Number of moles of the acidic compound contained in the cleaning composition×acid valence of the acidic compound)/(Number of moles of the foaming agent contained in the cleaning composition×Base valence of the foaming agent) is more than 0.1 and less than 1.5.

A degassing chamber for an ozone solution system includes a cylindrical housing defining a cavity. A mixture of water and ozone gas is delivered to the cavity, the mixture containing excess ozone gas. A cylindrical float is positioned centrally within the cavity to rise in accordance with the mixture column within the cavity. A piston is connected to move in accordance with the float. When the mixture level rises above a threshold, the piston the piston moves upward and seals an ozone outlet. As a pressure of ozone gas in the degassing chamber increases, the float is forced downward causing the piston to open a channel to an upper ozone outlet through which excess ozone gas is released. After removal of excess ozone gas, a mixture of water and ozone gas is output from the degassing chamber which is suitable for use as a general purpose cleaner.

A laundry treatment cartridge that includes a first sub-container and a second sub-container. The first sub-container contains and first laundry treatment composition. The second sub-container contains a second laundry treatment composition that differs from the first laundry treatment composition. The first sub-container and second sub-container are unitarily fixed with the cartridge.

Described herein is a powder detergent composition including a detergent active material including at least a surfactant system, and a granulated powder. The granulated powder includes particles made of: (a) a water soluble polymer matrix, and (b) an oil phase including a perfume dispersed in the water soluble polymer matrix, the oil being at least partly encapsulated in microcapsules. The granulated powder includes up to 30% by weight of encapsulated oil based on the total weight of the powder.

An object of the present invention is to provide a composition that exhibits excellent dissolving ability and etching selectivity (particularly, etching selectivity for a Ru-containing substance and other metal-containing substances) to metal-containing substances (particularly, a Ru-containing substance), a kit for preparing the composition, and a method for treating a substrate by using the composition.

The composition according to an embodiment of the present invention is a composition for removing metal-containing substances, and contains one or more periodic acid compounds selected from the group consisting of a periodic acid and a salt thereof, an azole compound, and an alkali compound.

The present invention relates to compounds which form, under perhydrolysis conditions, certain cationic organic peracids, to the use of said compounds for activating peroxygen compounds in the context of bleaching stains when washing textiles and cleaning hard surfaces, and to washing and cleaning agents that contain said compounds.
