  • Patent number: 6962944
    Abstract: Beta-lapachone, which is poorly soluble in most pharmaceutically acceptable solvents, has demonstrated significant antineoplastic activity against human cancer lines. The present invention overcomes this significant limitation by teaching novel pharmaceutical compositions comprising a therapeutically effective amount of Beta-lapachone, or a derivative or analog thereof, and a pharmaceutically acceptable solubilizing carrier molecule, which may be at water-solubilizing carrier molecule such as hydroxypropyl-?-cyclodextrin, or an oil-based solubilizing carrier molecule, for enhancing the solubility of Beta-lapachone in aqueous solution. The therapeutically effective amount of Beta-lapachone, or a derivative or analog thereof, may be complexed with the pharmaceutically acceptable solubilizing carrier molecule in aqueous solution. The novel pharmaceutical compositions may be administered with a second anticancer agent or in combination with radiation therapy.

  • Patent number: 6824785
    Abstract: A composition which when topically applied to the skin of a mammal reduces trans-epidermal water-loss and provides an improved epidermal barrier contains an aqueous dispersion of at least two lipids, preferably at least three lipids, in a non-crystalline phase lamellar array, preferably bilayer membranes in the form of liposomes. These lipids adopt a crystalline lamellar phase upon application to mammalian skin which resist washing with mild detergents and water. The composition can be formulated as a pharmaceutical preparation, and can be used in a method of recovering or otherwise improving a mammalian skin permeability barrier by administering the composition to the skin or hair and allowing the composition to dry. The dried composition adopts a crystalline lamellar phase after said administering to the skin. The composition thus provides a permeability barrier in cases where the natural barrier has been depleted, damaged or requires improvement.

  • Patent number: 6793929
    Abstract: Water-in-oil emulsions (a) with a content of water and optionally water-soluble substances totalling at least 75% by weight, and with a content of lipids, emulsifiers and lipophilic constituents totalling at most 25%, preferably at most 20%, based in each case on the total weight of the preparations, (b) whose oil phase is chosen from the group of lipids or lipid mixtures, where the total polarity of the lipid phase is between 20 and 30 mN/m, (c) comprising at least one interface-active substance, chosen from the group of alkylmethicone copolyols and/or alkyldimethicone copolyols, (d) optionally, but particularly when the content of water and water-soluble (hydrophilic) constituents is between 75 and 80% by weight, comprising one or more cationic polymers.

  • Patent number: 6793923
    Abstract: The present invention is concerned with vaccines and their preparation. An effective long-term immune response, especially in mammals, can be produced using a vaccine comprising an antigen encapsulated in liposomes, a suitable adjuvant and a carrier comprising a continuous phase of a hydrophobic substance. The vaccine is particularly effective in eliciting the production of antibodies that recognize epitopes of native proteins.

  • Patent number: 6783766
    Abstract: The present invention is a process of preparing an advanced cosmetic product by combining a high internal phase ratio (HIPR) emollient-in-water emulsion with a partial cosmetic formulation that typically contains water, fragrance, a rheology modifier, or a pH adjuster, or a combination thereof. The present invention is also a composition comprising two particular subclasses of HIPR emollient-in-water emulsions, namely an HIPR silicone elastomer-in-water emulsion and an HIPR sunscreen-in-water emulsion. The use of an HIPR emulsion of a cosmetic emollient provides a simple and flexible method of formulating the cosmetic product, due in part to the long shelf-stability of the HIPR emulsion (>1 year), and the low quantity of water in the emulsion (typically less than 20% by volume based on the volume of emollient and water).

  • Patent number: 6773627
    Abstract: Cubic liquid crystalline gel precursors, bulk cubic liquid crystalline gels, and dispersions of cubic liquid crystalline gel particles, and methods for their preparation, are disclosed. The precursors, gels, and dispersions can be used as skin penetration enhancers. The precursors, gels, and dispersions are prepared by methods employing hydrotropes that do not detrimentally affect the cubic liquid crystalline structure of the gels and particles.

  • Patent number: 6767865
    Abstract: Agrochemical suspension concentrates, particularly in aqueous or liquid oil based medium, comprise solid particles including one or more agrochemical active components; and a dispersing agent including a water soluble or dispersible styrene (meth)acrylic acid copolymer. In particular the styrene (meth)acrylic acid copolymer has a molar ratio of residues of (meth)acrylic acid monomer(s) to styrene monomer(s) from 20:1 to 1:5, particularly from 3:1 to 1:1. The formulation will usually also contain wetting agents; and/or adjuvants. The agochemical active can be plant growth regulators, herbicides, and/or pesticides, for example insecticides, fungicides, acaricides, nematocides, miticides, rodenticides, bactericides, molluscicides and bird repellants. The suspension formulations will typically be used diluted in water and sprayed onto plants or the soil surrounding the plants.
