    摘要: The invention relates to an aqueous agent which is provided for cleaning hard surfaces and which comprises a pH value of greater than 7. The inventive agent comprises: A) 5 to 45 wt. % of at least one polymer compound which is soluble in the alkaline medium, which is not cross-linked by metal ions, and which has a temperature of film formation ranging from 0 and 80 °C; and B) 2 to 90 wt. % of a surfactant combination comprised of a alkoxylated linear C8-C18 fatty alcohol with 1 to 10 ethylene oxide groups and 1 to 5 propylene oxide groups per molecule, whereby the free OH group can be closed by a C1-C4 alkyl group, and is comprised of at least one additional surfactant selected from the group comprised of alkoxylated branched-chain C8-C18 alcohols with 1 to 8 ethylene oxide units in the molecule, whereby the free OH groups can be closed by a C1-C4 alkyl group, C8-C18 fatty alcohol ethoxylates with 1 to 12 ethylene oxide units in the molecule and hydroxy mixed ethers corresponding to the following formula (I): R1O[CH2CH(CH3)O]x(CH2CHR2O)y[CH2CH(OH)]zR3 wherein R1 represents a linear, aliphatic hydrocarbon radical with an average of 4 to 18 hydrocarbon atoms in the molecule including the mixtures thereof, R2 represents a hydrogen atom or an alkyl group with 1 to 6 hydrocarbon atoms, and R3 represents a linear, aliphatic hydrocarbon radical with an average of 2 to 14 hydrocarbon atoms in the molecule including the mixtures thereof, x equals 0 or 1 to 5, y equals 1 to 30, and z equals 1 to 3.
