Abstract:
A water-based composition with a pH above 7 for cleaning hard surfaces, characterized in that it containsA) 5 to 45% by weight of at least one polymer compound which is soluble in the alkaline range, is not crosslinked through metal ions and has a film-forming temperature of 0 to 80Â° C. and B) 2 to 90% by weight of a surfactant combination of alkoxylated linear C8-18 fatty alcohol containing 1 to 10 ethylene oxide groups and 1 to 5 propylene oxide groups per molecule, the free OH group optionally being end-capped, by a C1-4 alkyl group, and at least one other surfactant selected from the group consisting of alkoxylated branched-chain C8-18 alcohols containing 1 to 8 ethylene oxide units in the molecule, the free OH groups optionally being end-capped by a C1-4 alkyl group, C8-18 fatty alcohol ethoxylates containing 1 to 12 ethylene oxide units in the molecule and hydroxy mixed ethers corresponding to formula (I): R1O[CH2CH(CH3)O]x(CH2CHR2O)y[CH2CH(OH)]zR3â€ƒâ€ƒ(I) â€ƒwhere R1 is a linear aliphatic hydrocarbon radical containing on average 4 to 18 carbon atoms in the molecule, including mixtures thereof, R2 is a hydrogen atom or an alkyl group containing 1 to 6 carbon atoms and R3 is a linear aliphatic hydrocarbon radical containing on average 2 to 14 carbon atoms in the molecule, including mixtures thereof, x=0 or 1 to 5, y=1 to 30 and z=1 to 3.
