Cleaning compositions for hard surfaces comprising a silyl polyalkoxylate

Abstract

Aqueous liquid compositions containing: (a) at least one alkyl ether sulphate (b) at least one multi-armed silyl polyalkoxylate of the formula (I) (H-A)-Z-[A-B—Si(OR)(R)](I), where Z is an (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 ≧1 and n is 0 or an integer ≧1, and m+n has a value from 3 to 100, and (c) 0-50% of at least one alkylsulphonate and/or arylsulphonate; (d) 0-15% of at least one alkyl sulphate and/or (e) 0-20% of at least one amphoteric surfactant cause an improvement of the drying and draining behavior in the cleaning of hard surfaces, in particular dishes.
