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.

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

The present invention comprises chlorinated and non-chlorinated alkaline cleaning compositions for removal of proteinaceous and fatty soils at low temperature, i.e. less than 120° F., with little or no deleterious affect on cleaning performance. According to the invention, applicants have found that adding additional alkalinity makes protein removal more difficult and reducing the amount of alkalinity actually improves performance. According to the invention optimized combinations of chlorine and alkalinity components for low temperature cleaning as well as a surfactant system optimized for low temperature fatty soil removal are disclosed.

Present invention relates to a detergent composition and a method for preparing the composition. The composition may be a compressed tablet, a coated tablet, in form of small granules or pearls packed in a dose unit. The composition may also be formulated so as to be an effervescent composition. The detergent composition may conveniently be used in the food industry for cleaning of appliances in food processing and preparation or in the metal industry for cleaning of appliances with respect to soot or oil residues.

Methods for the generation of non-equilibrium solutions of peroxyacetic acid are disclosed. These methods comprise introducing triacetin and aqueous hydrogen peroxide to water, mixing, and then adding an aqueous source of an alkali metal or earth alkali metal hydroxide. Triacetin is converted rapidly and with a high conversion rate into peracetic acid. These methods produce solutions with a high level of peracetic acid.
