Block-form cleaners for flush toilets which consist of at least two masses of different composition, one of the masses being at least partly surrounded by the other mass(es) and the surrounded mass containing an active substance in a concentration at least 1.3 times higher than in the surrounding mass. This distribution ensures that the active substance is more uniformly released over the useful life of the cleaning block.

Block-form cleaners for flush toilets

A cleaning block for the tank of flush toilets comprising: 10 to 30% by weight of monoalkyl sulfate, Na salt, 5 to 40% by weight of fatty acid alkanolamide, and 15 to 60% by weight of a water-soluble inorganic alkali salt, and optionally calcium-complexing carboxylic acids or alkali salts thereof, perfume, dye and other auxiliaries. The block is distinguished by a particularly long useful life, by uniform dissolving behavior and by high cleaning power. A method for use and process for manufacture are also afforded.

Cleaning block for flush toilet tanks

A two-component tablet for cleaning and disinfecting toilet flush tanks which adhere to the tank and will not be washed away and/or decomposed comprising extruded component A consisting essentially of (a) 10 to 50% by weight of an alkylbenzene sulfonate, (b) 0 to 40% by weight of inorganic alkali metal salts, (c) 0 to 10% by weight of at least one plasticizer, (d) 5 to 25% by weight of at least one disintegration rate regulator selected from the group consisting of fatty acid ethanolamides, fatty acid diethanolamides and stearic acid, (e) 0 to 50% of a disinfectant selected from a chlorine releasing compound or an active oxygen containing compound or acid and (f) 0 to 30% by weight of a complexing agent with the sum of (e) and (f), being greater than 5% and component B consisting essentially of (a') 20 to 55% by weight of an alkylbenzene sulfonate, (b') 15 to 45% by weight of inorganic alkali metal salts, (c') 0 to 10% by weight of at least one plasticizer, (d') 5 to 25% by weight of at least one disintegration rate regulator selected from the group consisting of fatty acid ethanolamides, fatty acid diethanolamides and stearic acid, (e') 1 to 10% by weight of perfume and (f') 5 to 15% by weight of dye, the sum of (c') and (e') being not greater than 10%, component A and B occupying different portions of the final tablet.

Two-component cleaner and disinfectant tablet

A two component tablet for cleaning and disinfecting toilet flush tanks which adhere to the tank and will not be washed away and/or decomposed comprising extruded component A consisting essentially of (a) 25 to 50% by weight of an alkylbenzene sulfonate, (b) 0 to 40% by weight of inorganic alkali metal salts, (c) 0 to 10% by weight of at least one plasticizer, (d) 5 to 20% by weight of at least one disintegration rate regulator selected from the group consisting of fatty acid ethanolamides, fatty acid diethanolamides and stearic acid, (e) 0 to 50% of a chlorine releasing compound or acid and (f) 0 to 30% by weight of a complexing agent with the sum of (e) and (f) being greater than 5% and component B consisting essentially of (a') 30 to 55% by weight of an alkylbenzene sulfonate (b') 15 to 45% by weight of inorganic alkali metal salts, (c') 0 to 10% by weight of at least one plasticizer, (d') 10 to 15% by weight of at least one disintegration rate regulator selected from the group consisting of fatty acid ethanolamides, fatty acid diethanolamides and stearic acid, (e') 1 to 10% by weight of perfume and (f') 5 to 15% by weight of dye, the sum of (c') and (e') being not greater than 10%, components A and B occupying different portions of the final tablet.
