Solid, water-degradable disinfectant and cleanser composition, and associated methods of manufacture and use

Patent Abstract

A disinfectant and cleansing composition is provided in the form of an extruded solid. The active agent in the composition is a halogen-releasing agent such as a halogenated 5,5-dialkylhydantoin. An inert binder such as a fatty acid salt or a hectoritic clay is used to enable manufacture of the composition using an extrusion process. Fragrance, colorants, and other pressure-sensitive materials may be included; fragrance and colorants are preferably incorporated in encapsulated form. Methods for manufacturing the compositions are also provided, as are methods for using the compositions in sanitizing water, particularly in disinfecting and cleansing flush toilets.
