Abstract
Liquid cleaning preparations for hard surfaces containing (a) 0.5 to 40% by weight, preferably 5 to 20% by weight, of a surfactant or a surfactant mixture; (b) 0.01 to 1% by weight, preferably 0.05 to 0.5% by weight, of cleaning enhancer; (c) 0 to 6% by weight, preferably 1.0 to 6% by weight, of at least one organic and/or inorganic builder; and up to a total of 100% by wiehgt, based on the total weight, of water, and optionally, one or more of solubilizers (solvents, hydrotropes), preservatives, antimicrobial agents, viscosity regulators, pH regulators, perfumes, and dyes. Component (b) is a mixture of (i) at least one polyacrylamide and (ii) at least one highly polyethoxylated monofunctional or polyfunctional alkanol.
Claims29
