  • Patent number: 6511650
    Abstract: This invention is directed to a new approach to form porous hydrogel materials by first creating gas pockets in the gel and then removing this gas. The removal of the gas creates a porous material, and the initial incorporation of sufficient gas allows one to create a material with an open, interconnected pore structure. Advantageous features of the resulting materials, in addition to their interconnected pore structure, may include that the pore structure is maintained over extended time periods and that the gels maintain a high mechanical integrity that allows seeding with cells and implantation without destruction or compression of the material.

  • Publication number: 20020054909
    Abstract: An insect-repelling agent contains N,N-diethyl-m-toluamide (DEET) based on alcohol solutions as the active ingredient (repellent), and further contains an adjuvant that extends the period of effectiveness of DEET following application to human skin. It is proposed that the sole adjuvant is glycerol in an amount of more than 10 percent by weight of the insect-repelling.

  • Patent number: 6375981
    Abstract: Film-forming compositions are disclosed that can comprise, on a dry solids basis, 25 to 75 percent by weight of certain starch derivatives having a DE less than about 1, 25 to 75% plasticizer, and 0.1 to 15% hydrocolloid gum. The starch derviatives can be chemically modified starches which range in molecular weight from 100,000 to 2,000,000. These starch-based systems can completely replace gelatin in edible film-forming applications such as soft and hard gel capsules.

  • Patent number: RE37890
    Abstract: Controlled release compositions of matter are disclosed comprising complexes for treating a population of one or more aquatic organisms in a column of water. The complexes comprise at least one system wherein the system comprises at least one bioactive agent as a component selected for treating a population of aquatic organisms, at least one carrier component, and at least one coating component for regulating the controlled release rate and release profile of the bioactive agent in water or at least one bioactive agent and one joint-function component that can serve as both a carrier and coating to regulate the controlled release rate and release profile of the bioactive agent in water, with or without optional binder components and/or additional formulation materials. The components are selected to sink or float so that the complexes will permeate and/or remain in any planar or volumetric segment of a water column for a period of time that is sufficient to effectively treat a population of aquatic organisms.
