Provided is a method of producing a quaternary alkyl ammonium hypochlorite solution with an excellent storage stability. Specifically, provided is a method of producing a quaternary alkyl ammonium hypochlorite solution, the method including: a preparation step in which a quaternary alkyl ammonium hydroxide solution is prepared and the concentration of amines in the quaternary alkyl ammonium hydroxide solution is set to 20 ppm by mass or less; and a reaction step in which the quaternary alkyl ammonium hydroxide solution is brought into contact with chlorine gas, wherein the concentration of carbon dioxide of a gas phase in the reaction step is 100 ppm by volume or less and the pH of a liquid phase in the reaction step is 10.5 or more.

Cleaning compositions e.g. containing one or more copolymers comprising structural units a) derived from one or more monomers comprising a sulfonic acid group or a sulfonate group, and structural units b) derived from one or more monomers comprising a carboxylic acid group or a carboxylate group and structural units c) derived from one or more cationic monomers are disclosed.

The cleaning compositions are e.g. suited to be used for the treatment of hard surfaces, for easier next time cleaning of hard surfaces and for preventing the build-up of limescale on hard surfaces.

Disclosed are a composite glass composition for washing and cleaning and a method for producing composite glass powder using the same, in which a silicate-based glass composition containing an alkali oxide for activating water into alkaline water and a bleaching agent having bleaching performance are mixed or coated. Accordingly, since the silicate-based glass composition containing an alkali oxide can ionize water in place of a surfactant contained in existing synthetic detergents, washing and cleaning capacity equivalent to or greater than existing synthetic detergents can be secured with alkaline water ionized from water.

A detergent composition includes a detersive surfactant and a graft polymer.

A method for pretreating and dyeing cellulose (2), comprising the steps of: providing a cellulose (2), carrying out a cationization reaction and carrying out a bleaching reaction by means of a bleaching agent, wherein the bleaching agent is stabilized by means of at least one stabilizer.

A method for pretreating and dyeing cellulose (2), comprising the steps of: providing a cellulose (2), carrying out a cationization reaction and carrying out a bleaching reaction by means of a bleaching agent, wherein the bleaching agent is stabilized by means of at least one stabilizer.

The invention relates to compositions and methods of treatment employing compositions comprising polyelectrolyte complexes. The compositions include a water-soluble first polyelectrolyte bearing a net cationic charge or capable of developing a net cationic charge and a water-soluble second polyelectrolyte bearing a net anionic charge or capable of developing a net anionic charge. The total polyelectrolyte concentration of the first solution is at least 110 millimolar. The composition is free of coacervates, precipitates, latex particles, synthetic block copolymers, silicone copolymers, cross-linked poly(acrylic) and cross-linked water-soluble polyelectrolyte. The composition may be a concentrate, to be diluted prior to use to treat a surface.

A bleach catalyst suitable for use in automatic dishwashing comprising a mixed metal oxide.
