Dentifrice composition, characterized in that it takes the form of a creamy gel containing at least one abrasive agent and at least one thickening agent which results from the ionic interaction in aqueous medium between a cationic polymer, consisting of a copolymer of cellulose or cellulose derivative grafted with a water-soluble quaternary ammonium monomer salt, and a carboxylic anionic polymer having an absolute capillary viscosity in dimethylformamide or methanol, at a concentration of 5% and at 30 DEG C., of less than or equal to 0.08 Pa.s, this thickener having an Epprecht-Drage, module 3, viscosity in 1% strength solution in water at 25 DEG C. greater than or equal to 0.45 Pa.s. |
