Patent ID: 7897554

Claim:
A composition for cleaning a glass surface, comprising: a) 0.05 to 10 wt. % of at least one multi-arm silyl polyalkoxylate of formula (I) (H-A) n -Z-[A-B-Si(OR 1 ) r (R 2 ) 3−r ] m (I) in which Z stands for an (m+n) valent group having at least three carbon atoms, A stands for a (co)polymer of ethylene oxide and propylene oxide having a propylene oxide content of up to 30% by weight, wherein the (m+n) (co)polymer groups A that are bonded to Z can be different from one another, and wherein one A group is bonded to Z through an oxygen atom that belongs to Z, and one oxygen atom that belongs to A is bonded to B or hydrogen, B stands for a chemical bond or for a divalent organic group having 1 to 50 carbon atoms, OR 1 means a hydrolysable group, R 1 and R 2 independently of one another mean a linear or branched alkyl group containing 1 to 6 carbon atoms and r stands for a whole number from 1 to 3, and m is a whole number ≧1 and n stands for 0 or a whole number ≧1, and m+n has a value from 3 to 100; b) 0.1 to 40 wt. % of at least one non-ionic surfactant; and c) optionally water and/or one or more corrosion-protection agents, acidifiers, non-aqueous solvents and solubilizers.
