  • Patent number: 6676956
    Abstract: The invention relates to an oil-in-water emulsion comprising, as an active ingredient, &agr;-tocopherol or the stereoisomers thereof and comprising, as an emulsifier, phospholipids. The inventive emulsion is used in order to attain a protective action against damages to human organs resulting from peroxidation. The emulsion contains a &agr;-tocopherol content, with regard to action, of 1.48 g/l to 30 g/l RRR-g(a)-tocopherol, 0-25 g/l of an oil which is compatible with I.V. administration, and 0.25 g/l to 3 g/l of a phospholipid. The emulsion is preferably administered as an infusion and is especially used to reduce damages resulting from peroxidation due to ischemia and /or reperfusion and, among other things, during an organ transplantation.

The allantoin-containing composition is a water-in-oil emulsion that includes allantoin and an emulsifier system that includes at least one emulsifier that is either an anionic emulsifier or a nonionic emulsifier. If the emulsifier is an anionic emulsifier, the emulsifier system can include beeswax. The nonionic emulsifiers used can include at least one nonionic emulsifier that is an ethoxylated ether or an ethoxylated ester whose carbon chain length ranges from 8 to 22 carbon atoms. Alternatively, the emulsifier system can include an acidic anionic polymer such as carboxypolymethylene and an anionic emulsifier. In another alternative, the emulsifier system can include the acidic anionic polymer and a nonionic emulsifier, or the acidic anionic polymer alone.

  • Patent number: 6645463
    Abstract: A surface-modified lipoprotein-like oil-in-water emulsion useful as a blood-pool selective delivery vehicle for lipophilic imaging agents or lipophilic derivatives of water-soluble imaging agents. The blood-pool selective delivery vehicle remains in the blood for several hours, shows very little early hepatic sequestration, and is cleared from the blood within 24 hours. The mean diameter of the oil phase is less than 150 nm which minimizes sequestration by the reticuloendothelial system. The surface of the oil phase is modified with a polyethyl glycol-modified phospholipid to prevent normal interactions with the receptor sites of the hepatocytes.

    Abstract: The present invention provides a nanoemulsion, that includes: an oily phase dispersed in an aqueous phase; and at least one glycerol fatty ester surfactant which is solid at a temperature of less than or equal to 45° C.; wherein the oily phase includes oil globules having a number-average size of less than 100 nm; wherein the oily phase includes at least one oil having a molecular weight of greater than 400; and wherein a weight ratio of the oily phase to the surfactant ranges from 2 to 10. The invention also provides a process for making the nanoemulsion and methods for its use. Ideally, the emulsion is transparent and stable on storage. It can ideally contain large amounts of oil while retaining good transparency and good cosmetic properties. The nanoemulsion is particularly useful in the cosmetics and dermatological fields, in particular for moisturizing the skin and/or mucous membranes, as well as for treating the hair, and, in the ophthalmological field, as an eye lotion for treating the eyes.

  • Patent number: 6531500
    Abstract: An improved method of treating skin diseases comprises applying to the skin of a patient suffering such a skin disease an allantoin-containing composition in a therapeutically effective quantity. The allantoin-containing composition is a water-in-oil emulsion that includes allantoin and an emulsifier system that includes at least one emulsifier that is either an anionic emulsifier or a nonionic emulsifier. If the emulsifier is an anionic emulsifier, the emulsifier system can include beeswax. The nonionic emulsifiers used can include at least one nonionic emulsifier that is an ethoxylated ether or an ethoxylated ester whose carbon chain length ranges from 8 to 22 carbon atoms. Alternatively, the emulsifier system can include an acidic anionic polymer such as carboxypolymethylene and an anionic emulsifier. In another alternative, the emulsifier system can include the acidic anionic polymer and a nonionic emulsifier, or the acidic anionic polymer alone.
