Abstract

Polyasparaginic acid and condensates of asparaginic acid containing up to 40 % by moles of other condensed aminoacids, as well as the alkali and ammonium salts of these condensates and of polyasparaginic acid, are used in cleaning product formulations for cleaning machines in food and beverage industry installations. Also disclosed are aqueous cleaning product formulations which contain (1) 0.05 to 30 % by weight polyasparaginic acid, condensates of asparaginic acid containing up to 40 % by moles of other condensed aminoacids, the alkali and ammonium salts of said condensates and/or of polyasparaginic acid; (b) 2 to 50 % by weight alkali metal hydroxide, carbonate or silicate or their mixtures and (c) 1 to 30 % by weight surfactants.
