Abstract (en)
[origin: US4808329A] A paste-form glass cleaning preparation having the composition: (a) from 2 to 30% by weight of gasoline having a boiling point in the range of from 120 DEG to 250 DEG C. (b) from 0 to 10% by weight of organic solvent selected from the group consisting of alcohols, ketones and glycol ethers having a boiling point in the range of from 55 DEG to 250 DEG C., the organic solvent content making up less than half the gasoline content, (c) from 5 to 40% by weight of microcrystalline calcium carbonate wherein more than 98% by weight of the particles are smaller than 300 mu m, (d) from 0.2 to 2.5% by weight of silicone oil having a viscosity of from 20 to 1000 mPas, (e) from 0.05 to 2% by weight of nonionic and/or anionic emulsifier for oil-in-water emulsions, (f) from 0.1 to 3% by weight of polyacrylic acid having an average molecular weight of from 0.8x106 to 5 x106, (g) from 0 to 2% by weight of alkali metal selected from the group consisting of alkaline reacting alakli metal salts, ammonia and alkanolamines, (h) from 0 to 3% by weight of other standard auxiliaries, and (i) ad 100% by weight of water. The preparation is distingushed by extremely high cleaning power and minimal residue formation and may be conveniently and cleanly handled.
