摘要

USE OF A COMBINATION OF IONIC AND NON-IONIC SURFACTANTS The present invention relates to the use for cleaning hard surfaces of a combination of ionic and nonionic surfactants containing (a) at least one quaternary ammonium compound having the general formula (I) R1(-CHOH-CHR2)n-N+R3R4R5 X- (I) wherein R1 represents a linear or branched alkyl group having from 1 to 22 carbon atoms; R2 represents hydrogen or a linear or branched alkyl group having from 1 to 21 carbon atoms, the total number of the carbon atoms of the substituents R1 and R2 being within the range of from 9 to 22; n = 0 or 1; R3 and R4 represent methyl, ethyl, 2-hydroxyethyl or hydroxypropyl; R5 represents an alkyl group having from 4 to 6 carbon atoms or a phenylalkyl group having from 1 to 3 carbon atoms in the alkyl moiety; and X- represents a halide or the anion of an organic acid having from 4 to 15 carbon atoms; and (b) at least one alk(en)yl polyethylene glycol mixed ether having the general formula (II): R6-O-(CH2CH2-O)8-R7 (II), wherein R6 represents a linear or branched alkyl group or alkenyl group having from 6 to 18 carbon atoms or a cyclic alkyl group having from 5 to 6 carbon atoms; s represents a number within the range of from 2 to 5; and R7 represents a linear or branched alkyl group having from 1 to 8 carbon atoms or a benzyl group, the ratio by weight of the components (a):(b) being within the range of from 20:1 to 1:20.
