    Abstract: A dental-care composition having improved shelf life in respect of rheology and abrasiveness, which as a novel feature, contains, as a cleansing agent, a bifunctional (thickening and abrasive) precipitated silica characterized by the following physico-chemical properties: -Pendulum - roller - mill Jet mill -BET surface area m2/g 15-110 15-110 -Tamped density g/l 150-750 90-650 -Secondary particle size FIG. 1 FIG. 2 -distribution according to -Coulter Counter -"ALPINE" screen % by 63 mu m weight -Cu abrasion in 10% mg 5-30 5-30 -strength glycerol disper- -sion -Lightness value A % 86-96 90-96 -Viscosity in a 30% 30,000-60,000 30,000-60,000 -strength dispersion in a -1:1 glycerol/water -mixture, Brookfield RTV, -Sp5 - The dental-care composition may additionally contain 0.5-5% by weight of polyethylene glycol or 2-14% by weight of a precipitated silica which in 15% strength dispersion in a glycerol/water mixture has a viscosity of not less than 30,000 mPa.s. Pyrogenic silica can also be employed successfully to regulate the viscosity of the product.
