VERWENDUNG EINER KOMBINATION NICHTIONISCHER TENSIDE

摘要

The invention concerns the use, for cleaning hard surfaces, of a combination of non-ionic surface-active agents, the combination containing: (a) at least one alk(en)yl ethoxylate of general formula (I): R<1>-O-(CH2CH2O)n-H, in which R<1> is a straight-chain or branched-chain alkyl or alkenyl group with 6-18 C-atoms or a cyclic alkyl group with 5-6 C-atoms, and n is a number in the range from 2 to 12, and (b) at least one alk(en)yl ethoxylate propoxylate of general formula (II): R<2>-O-(CH2CH2O)p-A-H, in which R<2> is a straight-chain or branched-chain alkyl or alkenyl group with 6-18 C-atoms or a cyclic alkyl group with 5-6 C-atoms, p is a number in the range 2 to 10 and A is a group of the type -(CH2-CH(CH3)-O)q- or -(CH(CH3)-CH2-O)r-, the sum q + r being a number in the range from 2 to 8, the ratio by weight of components a and b being in the range from 10:1 to 1:10.
