PRODUCT FOR TREATING HARD SURFACES

Use of one or more polycarbonate-, polyurethane- and/or polyurea-polyorganosiloxane compounds comprising at least a carbonyl structural element (I) or its acid addition compound and/or their salts for the treatment of a hard surface and/or for the improvement of the cleaning capacity of a cleaner for a hard surface, is claimed, where the treated surface is protected against soiling and/or the removal of soiling from the surface is facilitated. Use of one or more polycarbonate-, polyurethane- and/or polyurea-polyorganosiloxane compounds comprising at least a carbonyl structural element of formula (-Y 1>-A-(C=O)-A-) (I) or its acid addition compound and/or their salts for the treatment of a hard surface and/or for the improvement of the cleaning capacity of a cleaner for a hard surface, is claimed, where the treated surface is protected against soiling and/or the removal of soiling from the surface is facilitated. Either A : S, O or NR 1>; Y 1>bivalent to polyvalent, preferably tetravalent, optionally saturated or aromatic hydrocarbon with up to 1000C containing one or more NR 2>, (N +>R 2>R 3>) (both preferred), O, (CO), NH, 2-1000 polyorganosiloxane unit with silicon atom (optionally substituted), preferably oligoethoxy and/or oligopropoxy (where its oligomerization degree is preferably 2-60) or oligoethylene imine (where its oligomerization degree is preferably 10-150000); or Y 1>A : nitrogen containing heterocyclic ring; R 1>H, optionally saturated or aromatic hydrocarbon with up to 40C containing one or more O, (CO), NH, NR 2>, preferably oligoethoxy and/or oligopropoxy, where its oligomerization degree is preferably 2-60 or oligoethylene imine, where its oligomerization degree is preferably 10-15,0000; R 2>optionally saturated, aromatic hydrocarbon with up to 40C containing one or more O, (CO), NH, preferably oligoethoxy and/or oligopropoxy, where its oligomerization degree is preferably 2-60 or oligoethylene imine, where its oligomerization degree is preferably 10-15,0000; and R 3>optionally saturated, aromatic hydrocarbon with up to 100C containing one or more O, (CO), NH, a bivalent residue, which forms cyclic structures within the Y 1>, preferably oligoethoxy and/or oligopropoxy, where its oligomerization degree is preferably 2-60 or oligoethylene imine, where its oligomerization degree is preferably 10-15,0000. Provided that: in formula (I) A, Y 1>, R 1>, R 2>, R 3>are not same when at least one of the residues of Y 1>is polyorganosiloxane unit wi
