[0126] Examples:

[0127] Table 1

[0128] Table 2

[0129] Form the processing block according to the following general process:

[0130] All the anhydrous ingredients except the bleaching ingredients are dry blended to form a premix, and then they are metered into the feed port of the twin-screw extruder at the same time as the bleaching ingredients in an appropriate amount. Operate the twin-screw extruder at a lower temperature and pressure. During the mixing process, a metered amount of diester component is injected into the extruder barrel through an inlet located downstream of the feed port. About one-third of the length. Twin screw extruders are used to form a homogeneous mixture of solid block components. Then, the homogeneous mixture leaving the twin-screw extruder is conveyed to the feed port of the single-screw extruder, which is used to compress the homogeneous mixture into a solid mass. Operate the single-screw extruder at a speed of 5rpm~45rpm ...

Abstract

Improved treatment blocks useful in the treatment of lavatory appliances, particularly toilets are provided. The improved treatment blocks are solid block compositions which comprise at least one detersive surfactant, a hydrocarbon solvent constituent, and one or more further optional constituents, including bleach constituents. The improved treatment blocks provide improved processing and handling characteristics. 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 block treatment compositions for providing active treatment compositions to sanitary fixtures such as toilet bowls or urinals. Background technique [0002] In the cleaning and / or disinfection treatment of sanitary ware, once installed, the solid treatment block requires little or no user intervention during its effective use period, so the solid treatment block is widely used. Such solid block compositions are believed to function in an automatic fashion, the effective functioning 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 block treatment compositions are typically used in one of two modes: either the "ITC" (or "in the tank") mode or the "ITB" (or "in the toilet") mode. When used in the former mode, the solid block treatment composition is placed in a water supply c...
