  • Patent number: 5587179
    Abstract: The pharmaceutical formulation in the form of an effervescent and/or disintegrating tablet or of instant granules contains at least one active ingredient having an irritating taste and at least one matrix which delays the release of the active ingredient and is present as an intimate mixture with the active ingredient particles or covers said particles and is applied to a carrier. The formulation releases at most 65%, preferably at most 50%, of the active ingredient in aqueous solution at room temperature within about 2 min but more than 70%, preferably at least 80%, of the active ingredient within max. 20 min, preferably max. 15 min, in 0.1N HCl at C. The matrix preferably contains at least one fatty ester and/or one wax, preferably having a melting point between and C., in particular between and C., and/or at least one cellulose derivative and/or at least one polymethacrylate.

  • Patent number: 5573777
    Abstract: The invention relates to a relatively pure pulverulent mannitol, having a moderate and not excessive friability of between 40 and 80% in a Test I, a low apparent density of between 300 and 525 g/l for a particle size cut of between 100 and 200 microns and, additionally, a specific particle size in the sense that it contains less than 30% of particles with a size of less than 75 microns. This pulverulent mannitol possesses remarkable functional properties which make its use particularly recommended as sweetening agent, texturizing agent or additive excipient or vehicle in the food and pharmaceutical industries.

  • Patent number: 5549903
    Abstract: The present invention relates to a microencapsulated chlorpyrifos or endosulfan composition comprising a polyurea shell and one or more photostable ultraviolet and visible light absorbent compound having a log molar extinction coefficient of from about 2 to 5 with respect to radiation having wave lengths in the range of about 310 to 450 nanometers, wherein said photostable ultraviolet and visible light absorbent compound does not react with the monomer used in building the polyurea shell. The result is a microencapsulated composition having unexpected long, extended insecticidal activity with high toxicity to target species and very low toxicity to non-target animals.

  • Patent number: 5441991
    Abstract: A phenolic, cesium-specific, cation exchange resin is prepared by neutralizing resorcinol with potassium hydroxide, condensing/polymerizing the resulting intermediate with formaldehyde, heat-curing the resulting polymer to effect cross-linking and grinding it to desired particle size for use. This resin will selectively and efficiently adsorb cesium ions in the presence of a high concentration of sodium ions with a low carbon to cesium ratio.
