The present invention relates to an aqueous dispersion of pigment(s) and/or filler(s) containing, as an additive, a saccharide composition containing at least 30% of hydrogentated monosaccharide(s) and/or disaccharide(s). The saccharide composition contains at least 75% of such saccharides, in particular sorbitol, mannitol and/or maltitol. The optimum introduction rate is somewhere between 1 and 3%, in dry weight in relation to the dry weight of pigment(s) and filler(s) of the dispersion. The dispersion according to the invention presents a Brookfield viscosity (20° C., 20 rpm) of between 100 and 4000 mPa.s and a viscosity instability index lower than 35%. The dispersion according to the invention can present a very high level of solid matter, for example from 72 to 80% and be used advantageously in numerous industries such as those connected with paper, paint and varnishes, inks, adhesives, detergents, textile materials and leathers, etc. The dispersion can contain various pigments or fillers such as clays (kaolins, smectites), calcium carbonates, talc, titanium dioxide, calcium or barium sulphates or sulfoaluminates.
