Hydrosoluble bar for use in toilet bowls and method of making same which includes an extrusion step

DETAILED DESCRIPTION What is claimed is: 1.
Composition for extruding a hydrosoluble toilet bowl bar which is solid at room temperature and adapted to dissolve in the flushing water of a toilet bowl, said composition comprising 10-40% by weight of paradichlorobenzene, 5-30% by weight of a paraffin sulfonate which improves the cohesion and consistency of the composition and is constituted by sulfonated alkyl chains having 14-16 carbon atoms 5-30% of a foamable anionic detergent other than a paraffin sulfonate, and at least 1-10% of at least one fatty amide which controls the speed of errosion of said bar.
2.
Composition as claimed in claim 1 in which the paraffin sulfonate contains about 95% monosulfonate and 5% polysulfonates.
3.
Composition as claimed in claim 1 which also contains 10-50% mineral salts which improve the cohesion of said bar and 1-5% perfume.
4.
Composition as claimed in claim 3 in which said amide is a monoethanolamide of a fatty acid.
5.
Composition as claimed in claim 3 in which said mineral salt is sodium sulfate.
6.
Hydrosoluble composition as claimed in claim 1 in the form of an extruded bar.
7.
Process of manufacturing a hydrosoluble product as claimed in claim 1 by extrusion in solid form, which process comprises the steps of mixing the constituents of said composition, rolling the resulting mixture at ambient temperature, extruding said mixture at a temperature between 10.

Description:
SUMMARY OF THE INVENTION In order to deodorize and clean toilet bowls it is conventional to utilize water-soluble products in solid form and, in particular, in the form of a bar, which is placed inside the bowls in a position such that it is eroded by the water during flushing.
The water-soluble bar progressively dissolves when brought in contact with the water and releases a small quantity of product at each flushing operation until it has been completely used up, so as to insure the cleaning and deodorization of the bowl in which it is located
