Abstract: The acids can be applied by adding them to substances for maintaining oral hygiene - in tooth pastes, topic fluoride preparation, dental materials or medical chewing gums. They have specific, delayed release of the active substance. They are produced by adding the active substance in the preparation of the sedimental silicic acid in the known manner. 4 claims, 2 figures

Abstract: A precipitated silica which contains an active substance with a characteristic, delayed release of active substance is prepared by adding the active substance during preparation of the precipitated silica. The precipitated silica containing the active substance may be added to oral hygiene agents such as toothpastes, topical fluoride preparations, dental materials or medicinal chewing gums.

Abstract: Precipitated silica having a BET surface area of 10-130 m /g, a CTAB surface area of 10-70 m /g, a mean particle diameter of 5-20 mu m, a Cu abrasion in 10% strength glycerol (glycerine) dispersion of 4-50 mg and a thickening behaviour in CMC solution (20% strength dispersion) of 300-3500 mPa.s is prepared by simultaneously adding alkali metal silicate (weight ratio SiO2: alkali metal oxide = 2.5-3.9:1) and a mineral acid to an initial charge of water which has been adjusted to a pH of from 7.0 to 9.9 or from 10.0 to 10.7 by addition of water, keeping the pH constant between 7.0 and 9.9 or 10.0 and 10.7, with the initial precipitation temperature being 50-90 DEG C and a viscosity increase commencing at the latest after 25% of the precipitation time, setting the pH to /= 160 g/l to 240 g/l, separating off the solid by filtration and washing, drying and milling it. The precipitated silica can be used as abrasive and/or thickening component in toothpastes.

Abstract: A precipitate of silica having the following physicochemical parameters: BET surface area: from 35 to 350 m /g Ratio of BET/CTAB surface area: from 0.8 to 1.1 Pore volume PV: from 1.6 to 3.4 ml/g Silanol group density (V2 = consumption of NaOH): from 6 to 20 ml Mean aggregate size: from 250 to 1500 nm CTAB surface area: from 30 to 350 m /g DBP number: from 150 to 300 ml/100 g V2/V1 according to Hg porosimetry: from 0.19 to 0.46 DBP/CTAB: from 1.2 to 2.4 is prepared by reacting alkali metal silicate with mineral acids at temperatures of from 60 to 95 DEG C while maintaining a pH of from 7.5 to 10.5 with continuous stirring, continuing the reaction to a solids concentration in the precipitate suspension of from 80 to 120 g/l, adjusting the pH to a value equal to or less than 5, filtering off, washing, drying and, if desired, milling or granulating the precipitated silica. The precipitated silica is used as filler in vulcanisable rubber mixtures and vulcanisates.
