Stabilized hydrogen peroxide-containing compositions and methods of making same are disclosed. The compositions contain a stabilizer system made up of a disulfonate surfactant, a diester solvent, and a sulfonic acid or a salt thereof in a sufficient quantity to provide the stabilized hydrogen peroxide with an acidic pH value. The compositions are suitable for use as disinfectants, as cleaning agents, and in various personal care applications such as hair care and tooth whitening.

A composition for sterilization and cleaning which comprises 0.001-30 mass % peracetic acid, 0.001-30 mass % hydrogen peroxide, 1-70 mass % acetic acid and/or salt thereof, 0.001-5 mass % polyoxyethylene lauryl ether acetate or salt thereof, and water, the composition having a pH of 4.0-10.0.

A modified aqueous acid composition comprising: nitric acid; sulfuric acid; a compound comprising an amine moiety and a sulfonic acid moiety; and a peroxide. Also disclosed are methods of using such composition.

A composition including hydrogen peroxide is provided, which can be used for semiconductor device manufacturing and which exhibits an excellent storage stability and has a reduced effect of defects on a semiconductor substrate. Further, a method is provided for producing the composition including hydrogen peroxide, and a composition reservoir for storing the composition. The composition includes hydrogen peroxide, an acid, and an Fe component, in which the content of the Fe component is 10.sup.−5 to 10.sup.2 in terms of mass ratio with respect to the content of the acid.

Peroxyformic acid compositions for removal of biofilm growth and mineral deposits on membranes are disclosed. In particular, peroxyformic acid compositions are generated in situ or on site generation for the reduction and prevention, of biofilms and the mitigation of mineral buildup on the membranes. The compositions according to the invention are compatible with the membranes under application of use conditions.

The present invention herein provides a disinfectant composition containing a) an effective amount of a hydrogen peroxide source, b) a blend of at least one aromatic alcohol and at least one glycol or glycol ether, c) at least one nonionic and/or anionic surfactant and d) at least one acid. Furthermore a method of using the disinfectant composition is also provided, whereby the composition can be applied to any surface and effectively kill a majority of tuberculosis and/or M. terrae microbes; resulting in a >5 log reduction at a contact time of 5 minutes or less.

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.

Provided therefore herein is a novel acidic fluoride activated cleaning chemistry. The present invention includes novel acidic fluoride activated, unique organic-solvent based microelectronic selective etchant/cleaner compositions with high metal nitride etch and broad excellent compatibility, including tungsten (W) and low-k. It does not use W-incompatible oxidizers, such as hydrogen peroxide or particle-generating corrosion inhibitors.

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.

The present invention relates to a an aqueous composition for removing soils from a surface to be cleaned, formed from water, a detergent mixture and a rinse aid, wherein the detergent mixture comprises a peroxidation catalyst and wherein the rinse aid comprises an oxygen source. Such a composition may provide a more effective cleaning behaviour. The present invention further relates to a method for removing soil from a surface to be cleaned comprising applying to the surface to be cleaned a composition according to the invention.
