Abstract: Method for preparing biocidal halogenated polystyrene hydantoins. The biocidal polymers poly-1,3-dichloro-5-methyl-5-(4?-vinylphenyl)hydantoin, poly-1,3-dibromo-5-methyl-5-(4?-vinylphenyl)hydantoin, and their monohalogenated alkali metal salts and protonated derivatives have been prepared as porous beads by use of highly crosslinked polystyrene beads as starting materials. The porous beads will be useful in water and air disinfection applications when employed in cartridge filters and carafes (for water), as well as for controlling noxious odor when mixed with absorbent materials in items such as disposable diapers, incontinence pads, bandages, sanitary napkins, pantiliners, mattress covers, shoe inserts, sponges, animal litter, carpets, fabrics, and air filters or the like.

Abstract: A powdered, dispersible composition having stable dispersibility over time is provided. The composition exhibits a characteristic glass transition temperature (Tg) and a recommended storage temperature (Ts), wherein the difference between Tg and Ts is at least about 10° C. (i.e. Tg−Ts is greater than 10° C.). The composition comprises a mixture of a pharmaceutically-acceptable glassy matrix and at least one pharmacologically active material within the glassy matrix. It may be further mixed with a powdered, pharmaceutically-acceptable carrier. It is particularly valuable in unit dosage from having a moisture barrier, in combination with appropriate labelling instructions.

Abstract: A fragrance sample is provided which is made from two plies of material. A wall is formed in the bottom ply which defines a well into which a fragrance sample is deposited. The top ply has a wall formed therein which interlocks with the bottom ply wall to cover and close the well. The two plies are then adhered together to form a liquid tight seal between the two plies.

Abstract: The present invention provides compositions and methods for increasing absorption of poorly absorbable antibiotics, particularly third generation cephalosporin antibiotics, in oral dosage solid and/or suspension forms. Specifically, the composition is comprised of a biopolymer that is preferably swellable and/or mucoadhesive, a poorly absorbable antibiotic, and a cationic binding agent contained within the biopolymer such that the binding agent is tonically bound or complexed to at least one member selected from the group consisting of the biopolymer and the antibiotic.

Abstract: A dermal or transdermal segmented dosage unit for administering a dosage of a pharmaceutical to the skin of a patient. The dosage unit of this invention includes a backing layer which is non-permeable with respect to a pharmaceutical to be administered by the dosage unit, a membranous layer that is permeable to the pharmaceutical, a biologically acceptable adhesive, an impermeable coating means for dividing and severing the dosage unit into pre-selected segmental areas corresponding to fractional dosages of pharmaceutical. The fractional dosages may be administered in any pre-selected combination.

Abstract: A device for delivery of copper to the skin for therapeutic effect. A flexible patch is formed of a matrix material embedded or intermixed with copper particles. The matrix material is selected for its compatibility with the human skin. The patch is held in a conforming manner by a sleeve or other means to retain the patch against a targeted skin area. A contact area of the patch contains at least a portion of the copper particles, the surfaces of which are put in contact with the skin. Silicone is a preferred matrix material. The invention includes elastic braces including a copper containing patch and designed for encompassing a knee, wrist or other portion of the body.

Abstract: Methods, compounds, and medicinal formulations utilizing biocompatible polymers for delivery of a drug, particularly for solubilizing, stabilizing and/or providing sustained release of drug from topical, implantable, and inhalation systems. Many of the methods, compounds, and medicinal formulations are particularly suitable for oral and/or nasal inhalation and use polymers of the formula --[X--R.sup.1 --C(O)]-- wherein each R.sup.1 is an independently selected organic group that links the --X-- group to the carbonyl group, and each X is independently oxygen, sulfur, or catenary nitrogen.

Abstract: A process for treating hair by applying thereto a composition in the form of an aqueous dispersion of a water-insoluble polymer having a glass transition temperature of -20.degree. C. to +70.degree. C. wherein the water-insoluble polymer is formed from monomers selected from the group consisting of esters of acrylic acid, esters of methacrylic acid and styrene, and the composition further contains a water-soluble polymer.

Abstract: The present invention provides a dressing consisting of a non-reinforced, apertured gel web, wherein the gel is substantially anhydrous and comprises a water-soluble, polysaccharide- or cellulosic-polymer and a humectant, for use in treating burns. The present invention also provides a method for making the dressing.
