  • Patent number: 6290978
    Abstract: Derivatized Arabinogalactan can be utilized in a variety of compositions to impart functionality without imparting negative rheological affects when the amount of the derivatized Arabinogalactan is increased in the composition. This is particularly important in the personal care industry, where it is desirable to have the flexibility to adjust the amount of derivatized Arabinogalactan depending upon the results it is desired to deliver to the user without negatively impacting the overall viscosity of the personal care composition.

  • Patent number: 6287548
    Abstract: The present invention provides a composition of matter which has been demonstrated to be a very effective treatment for acne, seborrheic dermatitis and related skin diseases when applied to and contacted with affected skin areas, while avoiding the disadvantages and complications attendant to more established treatments. The composition comprises a synthetic mixture of salts which, when dissolved in a solvent such as water, is ionically composed primarily of a mixture of sodium and magnesium cations and chloride and sulfate anions, and which is preferably free of added zinc. More specifically, the salt mixture according to the present invention comprises the following range of composition in grams/kilogram of salt mixture in the ionic state, the balance being water of hydration: I.

  • Patent number: 6277402
    Abstract: A method for treatment of multiple sclerosis and related disease states. A histamine H2 mimicking agent is administered in an amount which is effective to stimulate production of a cyclic AMP in the body. A phosphodiesterase inhibitor is administered in conjunction with the histamine H2 mimicking agent to conserve the cyclic AMP which is thus produced. It is believed that the increased cyclic AMP levels serve to maintain the patient's myelin against self degeneration. The histamine H2 mimicking agent may be histamine phosphate and the phosphodiesterase inhibitor may be caffeine. The histamine H2 mimicking agent and the phosphodiesterase inhibitor may be mixed in a gel and administered using a transdermal patch.

  • Patent number: 6231889
    Abstract: The components of this invention are chosen because of their complementarity for the prevention or treatment of diseases caused by the herpes simplex virus. L-Lysine favorably increases the physiologic immunomodulation necessary for defense against this virus. Zinc improves and maintains a normal immune response. 2-Deoxy-2-D-glucose and heparin sodium alter the surface interaction between the herpes virus and the cell, preventing fusion and infectivity. N-Acetyl-L-cysteine increases glutathione levels thereby creating a thiol redox barrier to the virus at the cell membrane. Quercetin reduces intracellular replication of the herpes virus and viral infectivity. Ascorbate, in concert with copper and D-&agr;-tocopherol, provides an antioxidant defense against the herpes virus, which tends to lose latency during period of oxidative, free radical excess. Selenium and quercetin also participate in reducing various oxidative stresses.

  • Patent number: 6228811
    Abstract: The formation of undesirable sludge in the course of spraying a solution or dispersion of a water-soluble or water-dispersible solid or a structured gel formulation is reduced by the incorporation in the formulation of a low-density solid particulate material having a density of less than one and a diameter of less than the spray nozzle filter through which it will pass. The low-density solid particulate material is preferably a hollow glass or plastic particle having a density of less than 0.8 g/cm3. The invention is particularly applicable to agrochemical formulations.

  • Patent number: 6224852
    Abstract: The present invention teaches liquid sunscreen compositions in which level of surfactant is higher than level at which the sunscreen component(s) are still soluble in the surfactant in which they are used; and which comprise minimal levels of cationic polymer. Combination of cationic polymer (especially preferred surfactants and at minimum levels) and minimal levels of sunscreen lead to compositions with minimal levels of deposition and minimal SPF. Further, the compositions also maintain good lather.

  • Patent number: 6214318
    Abstract: Aerosol compositions are provided that enhance the therapeutic action of ointments by producing, upon topical application thereof, a sustained cooling effect that provides fast relief form pain and itching as well as a tendency to shrink swollen, inflamed tissue. The compositions contain oils, thickening agents for the oils, and propellant. Aqueous solutions, therapeutic ingredients and various adjuvants may also be present. The specific propellant and the proportion used are selected to provide a deposit with a temperature of about −5° C. to about +5° C. In this temperature range, the deposit is cold enough for the required therapeutic effect, but not so cold as to cause pain or tissue damage. The choice and proportion of thickening agents used are selected to provide a deposit that does not flow or spread. Were the deposit to spread, it would present a large surface area from which propellant present in the deposit would evaporate rapidly.

  • Patent number: 6211393
    Abstract: Silicon compound of general formula a), in which A, B, C, D are radicals which are different from OH and are covalently bonded to Si; two or three of these bond that are linked to Si are Si—O—C, Si—S—C or Si—N—C type bonds and are hydrolyzable in vivo, forming Si—OH bonds that are biologically active especially when in contact with living tissue, the A and D bonds of formula b) being invariably hydrolyzable; at least one of the hydrolyzable bonds corresponds to an acyloxy, aryloxy or vinyloxy radical; at least one of the compounds obtained after hydrolysis of the hydrolyzable bonds is a stabilizer, and the non-hydrolyzable bonds, which are of the Si—C type, correspond to hydrocarbon or fluorocarbon radicals for which Si is not directly linked to the phenyl ring.

  • Patent number: 6200557
    Abstract: A solution or gel composition containing activated stabilized chlorine dioxide and phosphates, such as disodium hydrogen phosphate, sodium dihydrogen phosphate, trisodium phosphate, and sodium monofluorophosphate, is disclosed for destroying HIV. The preferred concentration ranges are between about 0.005%-2.0% chlorine dioxide, and between about 0.02%-3.0% phosphate. The phosphate compound retards escape of chlorine dioxide in the pH range of 6.0 to 7.4, at which pH stabilized chlorine dioxide becomes activated and releases sufficient chlorine dioxide to reduce motility and become lethal to the involved micro-organisms. Using a lubricant as a vehicle for the chlorine dioxide/phosphate composition; development of vaginal itching due to Candida Albicans will be stopped.
