Embodiment

[0176] Blocks having the composition of the table below were produced by extruding the components into blocks of size 20 mm x 10 mm x 75 mm, wherein the surface area / volume ratio of the blocks was 4500 mm 2 / 15000mm 3 , or 0.3. The individual components are listed in Table 1 below by weight percent, and unless otherwise stated, each component is considered to be 100% by weight active.

Abstract

Improved treatment blocks useful in the treatment of lavatory appliances, particularly toilets are provided. The improved treatment blocks are solid block compositions which provide an extended service life, particularly when used in an ITB device. Methods of producing the solid block composition and treatment blocks therefrom, as well as methods of use are also disclosed.

Description

technical field [0001] The present invention relates to improved solid treatment block compositions for providing active treatment compositions to sanitary fixtures such as toilet bowls or urinals. More particularly, the present invention relates to improved solid block cleaning compositions having extended pot life when used for said purpose. Background technique [0002] In the cleaning and / or disinfection treatment of sanitary ware, once the solid treatment block is installed, the user needs little or no intervention on it during its effective use period, so the solid treatment block is widely used. Such solid treatment block compositions are believed to function in an automatic fashion, the effectiveness of which depends largely on their composition, their solubility characteristics when in contact with water, and their location in the sanitary ware they are used to treat. Such solid treatment block compositions are typically used in one of two modes: either the "ITC" (...
