摘要： 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 film forming constituent, optionally a bleach constituent and one or more further optional constituents. The improved treatment blocks provide good detersive characteristics and further provide a film forming material which contacts the surfaces of the lavatory appliance, e.g., toilet, in which the block compositions are used. Methods of producing the solid block composition and treatment blocks therefrom, as well as methods of use are also disclosed.

摘要： The present invention relates to a method for the manufacture of a cageless lavatory dispensing device useful for the delivery of at least one treatment composition, preferably a cleaning composition and/or a sanitizing composition to a sanitary appliance. The treatment composition comprises titanium dioxide which improves the visual surface appeareance of the compressed solid block of the composition following contact with and erosion by water such as flush water in a toilet.
