  • Patent number: 6858212
    Abstract: Provided is a process of and product resulting from adding a sub-lethal amount of a peroxide, or said peroxide in combination with sub-lethal ultra violet radiation, to a growing culture of a yeast; observing the change in absorbance of the culture at 256 nm as a measure of the injury occurring to the yeast cells, and upon reaching a predetermined absorbance value, purifying the water-soluble yeast extract from the peroxide containing yeast culture. The resulting product has at least 1.5 respiratory units per mg dry weight and has significantly increased amounts of 15, 25 and 55 kilo Daltons (kD) molecular weight products compared to a Live Yeast Cell Derivative as determined by SDS slab gel electrophoresis. This product can be combined with a cosmetically acceptable carrier to provide a composition suitable for topical application to the skin.

  • Patent number: 5124313
    Abstract: The present invention provides methods for treating or preventing various dermatological conditions in humans, such as dry, cracked or damaged skin resulting from exposure to sunlight (ultraviolet radiation) and wind, aging effects, general skin dryness, e.g., deficient moisture content, and mild acne. These methods comprise applying an effective amount of a composition to the affected target area, the composition comprising a retinyl palmitate-polypeptide complex of apparent molecular weight of from about 5,000 to about 7,000 daltons, and an isoprenoid compound, e.g., a carotenoid such as beta-carotene.

  • Patent number: 5057497
    Abstract: Absorption of Tissue Respiration Factor (TRF) into the gingival tissues is materially enhanced when it is formulated as a non-astringent hydrophilic pharmaceutical composition containing penetration promoting substances which are both hydrophilic and lipophilic. Additionally, a highly efficient means for effecting absorption of TRF into the gingival tissues is to utilize liposomes as carriers for the TRF in a non-astringent pharmaceutical composition.
