Use of a liquid composition for cleaning hard surfaces

摘要: 1. The use of a liquid composition for cleaning hard surfaces, the containing in aqueous or solventcontaining solution non-ionic surfactants, builders showing an alkaline reaction and water-soluble polymers essentially consisting : a) from 0.1 to 10% by weight b) 0.01 2% which comprise non-ionic, weakly anionic cationic group including polyvinyl alcohols, pyrrolidones, cellulose ethers, polysaccharides, proteins polyacrylamides with average molecular weights 5000 10,000,000 preferably 20,000 2,000,000, mixtures these polymers, quantity polymer is present always being below that surfactant present, c) alkaline-reacting inorganic organic builders, and, addition, form demineralized water water-miscible solvents, proviso no protection claimed compositions (a) about 0.05 15% anionic, ampholytic zwitterionic thereof ; (b) 0.5 99% builder (c) 0.03 5% mixture improved removal dirt (1) watersoluble dispersible non-ionizing primary material, namely (i) alcohols having degree hydrolysis 60 100% polymerization 100 7000 (ii) pyrrolidones 50 6000 (iii) (2) ionizing polysaccharide salt, seaweed extracts, plant exudates, seed gums, animal extracts biosynthetic ratio material salt amounting between 4:1 1:4.
