  • Publication number: 20030165440
    Abstract: The invention relates to compositions for treating tooth and/or bone tissue that contain calcium phosphates, calcium fluorides or calcium fluorophosphates, all of which being poorly soluble in water, and polyelectrolytes. The compositions can be cured and are suited for the smoothing, the reconstruction, and the remineralizing treatment of tooth and bone tissue, especially for eliminating microroughnesses.

  • Publication number: 20030155668
    Abstract: The invention relates to a method for producing a suspension of an undecomposed meltable material having an average particle diameter of between 5 to 500 nm. The inventive method enables stable suspensions to be produced and is characterised in that it only requires a simple technical infrastructure in many production plants, it delivers high space-time yields, and can easily be scaled up.

  • Patent number: 6352737
    Abstract: The invention relates to the use of nanoscale sterols and/or sterol esters with particle diameters of 10 to 300 nm as food additives and as active substances for the production of hypocholesterolemic agents. The particular fineness of the particles promotes more rapid absorption by the blood serum after oral ingestion by comparison with conventional sterols and sterol esters.

  • Patent number: 5780420
    Abstract: The invention relates to sodium silicates with a modulus (molar ratio of SiO.sub.2 to Na.sub.2 O) of 1.3 to 4 in the form of a fine-particle solid in shard-like form or compounds containing these silicates with the ability to reduce incrustation when used as a builder component in detergents. These useful materials are distinguished in particular by the fact that they are in the form of an X-ray amorphous overdried material (primary drying product) with water contents below 15% by weight and apparent densities of the non-compacted solid granules of 500 g/l or lower which has been produced by drying of a water-containing sodium silicate preparation using a hot gas phase as the drying medium and/or by heating of a spray-dried sodium silicate with water contents of at least 15% by weight at temperatures of 120.degree.to 450.degree. C., if necessary accompanied or followed by the application of forces to produce the shard-like structure.

  • Patent number: 5215732
    Abstract: Method for producing alkali metal silicates from crystalline siliceous material and aqueous alkali metal hydroxide solution at high temperature and normal pressure, characterized in that cristobalite and/or tempered quartz sand are used as the siliceous material, and this material is reacted with aqueous, 20 to 50 wt. % sodium or potassium hydroxide solution at temperatures of 100.degree. to 150.degree. C. and normal pressure, the molar ratio of SiO.sub.2 to Na.sub.2 O or K.sub.2 O in the reaction mixture being between 2:1 and 1:7.
