A novel cationic liquid starchy composition and uses thereof in industry, in particular, as an additive in paper and cardboard production, as an additive for treatment of industrial water, either from paper or cardboard production or not, or for the preparation of such additives. The cationic liquid starchy composition is characterized by selected dry material, viscosity, total nitrogen content and pH values. The viscosity is 200 mPa·s with a maximum of 1000 mPa·s, (according to a T test). The nitrogen content is at least 0.6% with a maximum of 1.4% (dry/dry). The cationic liquid starchy composition can contain, at least one polyol, preferably a saccharide and used as is or after dilution. The composition is particularly suitable, for the preparation of adhesive agents, particularly of the ASA type for bringing into contact, directly or not, with a fiber composition having a raised calcium ion content.
