The invention relates to compositions for treating a hard surface, in particular for cleaning and/or dirt-repellent treatment of a hard surface, containing a) at least one multi-armed silyl polyalkoxylate of the formula (I) (H-A)-Z-[A-B&#x2014;Si(OR)(R)](I), where Z is a (m+n)=valent radical having at least three carbon atoms, A is a divalent polyoxyalkylene radical, wherein the m+n polyoxyalkylene radicals bound to Z can be different from one another, and wherein one radical A is in each case bound to Z via an oxygen atom belonging to Z, and one oxygen atom belonging to A is bound to B or hydrogen, B is a chemical bond or a divalent organic radical having 1 to 50 carbon atoms, ORis a hydrolysable group, Rand Rindependently of one another are a linear or branched alkyl group having 1 to 6 carbon atoms and r is an integer from 1 to 3, and m is an integer &#x2267;1 and n is 0 or an integer &#x2267;1, and m+n has a value from 3 to 100, b) at least one surfactant, c) water and/or at least one nonaqueous solvent, d) if appropriate further conventional components of surface treatment and/or cleaning compositions which are compatible with the remaining components of the composition.

Compositions for treating hard surfaces comprising silyl polyalkoxylates

Compounds of the Formula I, wherein Ais O or NH; Ais O or S; each of Rand Ris independently hydrogen, a methyl or C-C-saturated or mono- or doubly unsaturated, branched or linear hydrocarbon group; and Ris a C-C-saturated or mono- or doubly unsaturated, branched or linear hydrocarbon group wherein, each of R, Rand Rcomprises a heteroatom selected from the group consisting of O and S in the chain and/or is mono- or multiply-substituted by a substituent selected from the group consisting of halogen, hydroxy, C-C-alkyl, trifluoromethyl, C-C-alkoxy, C-C-aryl, and C-C-alkyl-C-C-aryl are useful for controlling the interaction process between microorganisms such as in the development and/or maturation of biofilms; multicellular swarm behavior; the concerted development of antibiotic resistances; the concerted synthesis of antibiotics; the concerted synthesis of pigments; the concerted production of extracellular enzymes; or the concerted production of virulence factors.
