Various types of surface-active products are known, usually in the form of Powders, granules and optionally also in the form of pastes and more or less thickened liquids be applied. Because of their great cleaning effect, they can be found in industry and households a wide range of applications, where it would also be partly desirable to have them in the form of pieces to use. Such known cleaning agents can only be used due to their properties Overcoming various difficulties into pieces such as laundry soap, toilet soap and the like. A product is obtained that easily crumbles. There has therefore been no lack of attempts the deformability of such surface-active substances and their cohesion through the addition of binders to promote the deformed products. One had to accept the disadvantage that these partially insoluble adhesives have no cleaning effect, so they are unsuitable for washing Foreign substances are present in the end product. To avoid this disadvantage, according to the present invention solid, bar-shaped detergents manufactured, which as a binder for the washing-active substances are not inert materials, but a Have a skeleton made of water-soluble substances which, in addition to their binding effect, also have a cleaning effect exhibit. The surface-active substances are embedded in this skeleton in a completely homogeneous form.

The production of these solid, bar-shaped cleaning agents takes place according to the invention in that one carboxylic or sulfonic acids or acid sulfuric acid esters with a hydrophobic chain with at least 8 carbon atoms in the presence of urea or its derivatives and polyethylene glycol or ethylene oxide or in the presence of vinyl or acrylic monomers, especially vinyl acetate, with alkali carbonates or -hydroxides neutralized at elevated temperature and the reaction mixture until the end of the Implementation keeps in liquid state. Here, the components of the cleaning agent are mixed in such a way that that within the mixture at the same time the exothermic neutralization reaction of the active substance and the Polymerization of suitable monomers or formation of a urea inclusion compound takes place. It has proven to be particularly advantageous to initiate the reaction by adding catalysts accelerate. Oxidizing substances, especially perborates, peroxides and percarbonates, are preferred added.

After completion of the neutralization of the reaction mixture, an intimate process for the preparation of solids is obtained according to the invention

Mixture of active ingredients with the polymerized soluble basic body or skeleton. This Mixture shows considerable cohesion without affecting its solubility properties, foaming power and the degree of cleaning is impaired. The product produced according to the invention therefore consists of a uniform homogeneous mass in the form of the basic body or skeleton of the active cleaning agent connects and binds, the detergent having the water solubility of all components causes.

The exact composition of the product or the selection of the ingredients depends on the type of desired end product, the required degree of cleaning effect and the intended use away.

Suitable starting materials for the preparation of the products according to the invention are given below listed:

1. Suitable anionic active substances are fatty acids, sulfonic acids from fatty alcohols, sulfonic acids from alkylbenzenes, acid sulfuric acid
