  • Patent number: 5789393
    Abstract: Water-soluble, high-viscosity grade cellulose ether compositions are useful for the reduction of serum lipid levels, particularly total serum cholesterol, serum triglycerides, and low-density lipoprotein (LDL) levels and/or attenuate the postprandial rise of blood glucose levels in animals. The pharmaceutical uses of compositions for reducing cholesterol levels additionally include the treatment of diabetes and/or hypercholesterolemia, with avoidance of many of the undesirable side effects associated with other forms of treatment. The composition may be in the form of a prehydrated ingestible composition, such as a gelatin, or a comestible, such as a cookie. In addition, the compositions of the present invention are palatable to the patient, thereby enhancing patient compliance with the regimen.
    Type: Grant
    Filed: June 7, 1995
    Date of Patent: August 4, 1998
    Assignees: The Board of Regents of the University of Michgan, The Dow Chemical Company

  • Patent number: 5766638
    Abstract: The present invention concerns cool-water dispersible powder formulations of high molecular weight hydroxypropyl methylcellulose which has been milled to a specified particle size, with or without encrustation or other surface treatment, for dispersion into consumable liquids or for formulation of dry-mix powders, sauces, instant set puddings and baked goods for human consumption. The formulation is used for reduction of serum cholesterol levels. A process for preparing the formulation and its mode of administration is also provided.

  • Patent number: 5281584
    Abstract: The present invention is directed to a baked food composition comprising food ingredients and a water-soluble cellulose ether which is useful for reducing the low-density lipoprotein serum cholesterol level of an animal. Use of a specific particle-size distribution of the water-soluble cellulose ether results in compositions which are more palatable than known compositions.

  • Patent number: 5014650
    Abstract: Disclosed is an animal litter comprising a porous, inert solid substrate and a dry, particulate cellulosic ether. When animal urine contacts the animal litter there are produced gelled agglomerates containing the animal urine, polymer, and solid substrate. The gelled agglomerates have sufficient mechanical integrity to be conveyed as discrete entities thereby permitting animal urine to be physically removed from the litter box.
