  • Patent number: 8685381
    Abstract: The invention provides skin protecting and penetrating, easy-to-administer base and active agent-containing compositions, such as those including hydrocortisone, for treating the skin of mammals for different dermatologic disorders. This is effected by topically administering effective amounts of the compositions thereto in forms that address the skin and mucosa of the mouth and lips, and the rest of the body. Additionally, an optional flavoring addition to these products affords significantly better tasting, and less bitter, compositions, allowing a more pleasant experience and better compliance by patients. The compositions include a unique formulation of FANCOL VB, Natunola Castor 1023, Finsolv TN, bees wax and, optionally, one or a plurality of plant or plant seed oils, fatty alcohols, fats and flavorings, in desirable weight percents thereof, in various forms, and preferably in a form of a solid roll-on stick in a variety of sizes and of a jar or pot.

  • Patent number: 6506223
    Abstract: A fuel pellet is produced by the combination of organic waste material with a binder obtained by direct liquefaction and/or fast pyrolysis of biomass material. Direct liquefaction and fast pyrolysis are carried out according to known liquefaction processes. The liquefied bio-binder base is mixed with additives, if desired, such as petroleum asphalt and cross-linking agents, in order to modify its characteristics to meet specific needs of particular applications, and the resulting mixture is mixed with organic-waste material preheated to 100° C. or more and allowed to react at about 150-200° C. Combustible extenders and fillers, reinforcing fibers, and cross-linking agents may be mixed with the organic material or the bio-binder base to provide additional specific properties to the mixture. The resulting well mixed mass is then pelletized or otherwise molded in conventional equipment.
