Abstract
A liquid cleaning preparation for hard surfaces comprising an amphoteric polymer compound containing both anionic and cationic centers in the molecular thereof. The polymer is obtained by copolymerization of a cationic vinyl monomer with an anionic vinyl polymer, and in a 0.01% solution of water having a German hardness of 16.degree.d produces irreversible hydrophilization of polyvinyl chloride with increments in the wetting tension of at least 3 mN/m. The preparation may contain an anionic, nonionic, cationic or amphoteric surfactant or mixtures thereof. The polymer compound is present in an amount of from about 0.01% to about 10% by weight, based on the weight of the preparation, and the surfactant is present in a weight ratio of polymer to surfactant of from about 20:1 to about 1:1.
