Glass cleaner composition added with cationic polymers

The invention relates to a glass cleaner composition added with cationic polymers. The glass cleaner composition comprises the following materials: (a) cationic polymers which account for 0.01-3.0 percent of the total weight of the composition, have the general formula shown in the description and have the number-average molecular weight of 40,000-1,000,000, wherein R1 and R3 are one or more of ingredients shown in the description, and R2 is one or more of diallyl-dialkyl-ammonium chloride and N-(quaternary ammonium alkyl)acrylamide; (b) short-carbon-chain fatty alcohol which accounts for 4-40 percent of the total weight of the composition and has 1-4 carbon atoms; (c) a surfactant system which accounts for 0.1-5 percent of the total weight of the composition and at least comprises an ampholytic surfactant or an anionic surfactant; (d) at least one alkali of which the amount is enough to enable the pH value of the composition to range from 5 to 11; (e) one or more washing assistants; (f) the balance of water. The glass cleaner composition added with the cationic polymers can effectively improve the surface hydrophilicity of glass and has relatively good washability.
