  • Solid dosage forms
    Patent number: 5830576
    Abstract: A composition for agricultural and other actives, comprising a finely-divided particulate combination of microcrystalline cellulose, at least one nitrogen compound such as urea, an ammonium sulfate or phosphate and, optionally, a suspending agent for the micro-crystalline cellulose. The composition can be compacted to form shaped, solid dosage forms such as tablets which disintegrate rapidly in an aqueous medium.
    Type: Grant
    Filed: May 23, 1997
    Date of Patent: November 3, 1998
    Assignee: FMC Corporation
    Inventors: Dev K. Mehra, Nagui I. Ibrahim, Edwin G. Fleck, Jr.

  • Cold water soluble films and film forming compositions
    Patent number: 5272191
    Abstract: The rate of disintegration in cold water of water soluble packaging films is improved by incorporating into a film forming polymer composition, to form a dry blend or aqueous dispersion, a substantially water insoluble cellulose material prepared from alkali metal salts of carboxy(lower alkyl) cellulose or hydroxy(lower alkyl) cellulose. The increased disintegration is achieved without loss of film stability and, in some cases, the film stability is improved.
