A thickening system constituted of: a) at least one pregelatinised starch, b) at least one gum of plant or microbial origin, c) and at least one cellulose derivative. A method for producing a thickened and stable system, consisting in the steps of: a) providing an aqueous solution, b) heating the water to a temperature of between 20°C and 80°C, preferably between 20°C and 50°C, c) introducing at least one pregelatinised starch, at least one non-ionic polysaccharide and at least one anionic polysaccharide into the aqueous solution, d) stirring the medium until the constituents are dispersed in the water.
