  • Patent number: 4925671
    Abstract: Pressure sensitive adhesive having favorable adhesive, shear, liquid permeability, and release characteristics. The adhesive is a crosslinked polymerization product of a methyl/phenyl siloxane gum, dimethyl siloxane gum and a polysiloxane resin. The resulting product provides suitable adhesion to a large number of surfaces and has particular utility as an adhesive between plastic film and human skin, especially for use with transdermal therapeutic devices. The adhesive characteristic mitigates damage to underlying surfaces such as human skin tissue during adhesive removal.

  • Patent number: 4863764
    Abstract: A method for achieving the flame retardancy of polypropylene fiber and for fabrics which include such fibers has been devised which has a low add-on finish. The finish comprises a mixture containing a bromochlorinated paraffin having a high concentration of bromine, up to 80% by weight, but, notwithstanding low add-on, the invention will produce an extremely effective fire retardancy where the bromine and chlorine constituents equal 20% and 40% respecively by weight of the bromochlorinated paraffin. Antimony oxide, preferably a antimony pentoxide is used, having a preferred particulate size in the range of 30-50 millimicrons. The quantity of antimony oxide to be used may be 1/3 mole to 1 mole of bromine. After the bromochlorinated paraffin is combined with emulsifiers to form a stable premix, the premix and antimony pentoxide are preferably combined with a binder consisting of an ethylacrylate latex.

  • Patent number: 4844903
    Abstract: The process results in an adhesive plaster for the transdermal adminstration of pharmaceutical, in particular heat-sensitive, active substances, composed of an adhesive layer, a backing layer, a matrix layer containing the active substances, and a protective layer. The flux of active substance release is controlled by its diffusion from the matrix layer. The latter is produced by the hot melt method, by mixing an ethylene/vinyl acetate copolymer and an involatile, hydrophobic excipient which is miscible with the latter, is compatible with the active substance and is tolerated by the skin, for example isopropyl myristate or a triglyceride, at the melting point of the mixture, and incorporation therein of a solution or dispersion of the active substance in a small amount of the same excipient.

  • Patent number: 4822613
    Abstract: A water-soluble, foamable, insecticidally-active composition is disclosed. Also disclosed are methods for producing such a composition. The water-soluble, foamable, insecticidally-active composition comprises an aqueous phase, an insecticidally-active toxicant, and a foam-causing ingredient. The aqueous phase comprises water. The foam-causing ingredient must be capable of dispersing the insecticidally-active toxicant throughout the aqueous phase, to produce a toxicant-in-water dispersion. The foam-causing ingredient is present in an amount effective to enable the toxicant-in-water dispersion to form-in-place a water-soluble and insecticidally-active foam. The water-soluble aspect of the foam allows dissolving the foam (utilizing sufficient water) when desired.

  • Patent number: 4818540
    Abstract: Transdermal fertility-controlling absorption polymer matrix dosage units have been developed which comprise a backing layer, an adjoining layer of a solid polymer matrix in which minimum effective daily doses of an estrogen and a progestin are microdispersed and released for transdermal absorption. Presently preferred is use of the natural estrogen, 17-beta-estradiol, and of the progestin, levonorgestrel. The units have a biologically acceptable adhesive polymer layer. The polymer matrix as well as the adhesive layer can have dispersed one or more skin permeation enhancers. Dosage units are provided which transdermally deliver at least minimum daily doses of the estrogen and progestin for multiple days, such as for one week. The invention also provides a process of fertility control using the novel polymer matrix dosage units for the first three weeks of consecutive menstrual cycles of the subject desiring fertility control.
