  • Patent number: 7431940
    Abstract: Methods for treatment of human skin damaged by laser treatment or chemical peelings comprise the topical application of an effective amount of a lamellar oil-in-water system. In accordance with the methods, the lamellar oil-in-water system comprises at least one vegetable oil as the oily component, a hydrogenated phospholipid as emulsifier comprising not more than 10 percent by weight of negatively charged phospholipids with the remainder being neutral phospholipids, and sodium carboxymethyl ?-glucan (Sodium Carboxymethyl Betaglucan) as a compound for improving wound healing. The lamellar oil-in-water system used in the method may further comprise coenzyme Q10 as a compound for improving skin regeneration.

  • Patent number: 6558941
    Abstract: Nanoemulsions are prepared containing oily droplets of a diameter of less than 100 nm in an aqueous phase. The oily droplets contain a lipophilic substance, and have on their surface an amphoteric emulsifier in an amount of preferably 0.65 to 0.75 parts by weight amphoteric emulsifier for one part by weight of oily component forming the droplets. The oily component of the droplets is preferably a triglyceride containing oleic acid and/or linoleic acid. The nanoemulsions, which may be sterile, are used for delivering into cells the lipophilic substance contained by the oily droplets. This delivery can be used to biotransform the lipophilic substance, promote cell differentiation, growth or biosynthesis of a desired substance, or to test for toxicity of the lipophilic substance.

  • Publication number: 20020132284
    Abstract: Nanoemulsions are used for completion of cell cultures with lipophilic substances promoting the biosynthesis of desired substances within the cells; as well as for the defined and reproducible uptake of lipophilic substances into the cells of cell cultures. Preferred nanoemulsions have oily particles of a diameter of less than 100 nm, the surface of which is bearing a monolayer of an amphoteric emulsifier, which oily particles comprise a lipophilic substance to be tested in or to be delivered to a cell culture, said oily particles, said lipophilic substances dissolved therein and the aqueous phase being sterile.

  • Patent number: 6342486
    Abstract: A method for treatment of skin includes topical application of a composition containing a therapeutically effective amount of a 1,3-beta-glucan ether derivative. Such application effectively provides treatment and/or prophylaxis of various skin-related problems, such as neurodermatitis and psoriasis, and reduces the evidence of aging by minimizing wrinkles. In an advantageous embodiment, the glucan ether derivative is present in the composition in a range of concentration of about 0.002% to about 8% by weight. In another embodiment the glucan ether derivative is advantageously carboxymethyl glucan sodium salt.
