Shaped bodies for the sanitary sector

Abstract

The invention relates to shaped bodies for the sanitary sector, preferably shaped bodies preventing or dispersing urine scale, which are also termed WC blocks or toilet blocks, for use in the household or public commercial sanitary facilities, containing polysuccinimide in combination with polyalkylene glycols or alkyl polyalkylene glycols and/or phosphoric acid and also disintegrants.

Description

Claims

1. A shaped body containing polysuccinimide, poly- or oligoalkylene glycols or alkyl polyalkylene glycols and/or phosphoric acid, tablet disintegrants and/or pore formers and surfactants.

2. A shaped body according to claim 1, wherein the polyalkylene glycol is polyethylene glycol.

3. A shaped body according to claim 1, wherein the surfactant is anionic, nonionic, cationic, amphoteric or zwitterionic.

4. A shaped body according to claim 3, wherein a petrochemical-based anionic surfactant is used.

5. A shaped body according to claim 4, wherein the petrochemical-based anionic surfactant is alkylbenzenesulphonate, alkanesulphonate or alkyl(ether) sulphate having uneven chain lengths, or a native-based anionic surfactant.

6. A shaped body according to claim 5, wherein the native-based anionic surfactant is fatty alkyl sulphate or fatty alkyl(ether) sulphate, soap or sulphosuccinate.

7. A shaped body according to claim 3, wherein the nonionic surfactants have on average 1 to 7 mol of ethylene oxide per mol of alcohol of ethoxylated C12-C18-fatty alcohols and the corresponding C11-C17-alcohols, higher ethoxylated alcohol of the stated chain length, amine oxide, alkyl polyglycoside, polyhydroxy fatty acid amide, fatty acid methyl ester ethoxylate gemini surfactant.

8. A shaped body according to claim 7, wherein the alcohol is a C13-C15-alcohol.

9. A shaped body according to claim 1, wherein the pore former is a zeolite.

10. A shaped body according to claim 9, wherein the Zeolithe is zeolite A, zeolite P, zeolite X or any desired mixture thereof.

11. A shaped body according to claims 1 additionally containing dissolution-supporting substances.

12. A shaped body according to claim 11, wherein the dissolution-supporting substance is soda, silicate or a salt of an organic or inorganic acid.

13. A shaped body according to claim 1 containing additional inorganic and organic, water-soluble or water-insoluble builder substances and cobuilders, bleaches, in particular peroxide bleaches, activated chlorine compounds, bleach activators and bleach catalysts, enzymes and enzyme stabilizers, foam inhibitors or dyes and fragrances.

14. A method of using a shaped body according to claim 1 for the sanitary sector.

15. A method of use according to claim 14 wherein the sanitary sector are toilets.

16. A process for manufacturing shaped bodies according to claim 1 wherein finely ground polysuccinimide or finely ground polysuccinimides partial hydrolysate is mixed with a poly- or oligoalkylene glycol or alkyl polyalkylene glycol and/or phosphonic acid, tablet disintegrants and/or pore formers and surfactants in a kneader and the mixture is then pressed to shaped bodies via an extruder.

17. A process according to claim 16 wherein additionally dissolution-supporting substrates are used.
