Abstract: This invention relates to compositions that are easily spreadable onto and adhesive to biomembranes. They contain and provide moisture to the biomembranes and do not readily flow off, i.e., leak from the biomembranes. Nor are they readily removed or washed from the biomembranes. Compositions that adhere to and are compatible with, in that they spread, and do not flow off and are not readily removed or washed from the biomembranes are deemed to be bioadhesive. Such compositions are particularly useful for maintaining biomembranes in a moist condition, for lubricating the biomembranes, and for providing a vehicle for containing and delivering medicaments, such as contraceptives, antifungals and antibacterials. The invention further relates to methods for making and methods of use of such compositions.

Abstract: An effective and convenient medicament delivery system comprising novel extrudable compositions. The preferred compositions of the invention contain a thermoplastic water-soluble polymer selected from the group consisting of hydroxypropyl cellulose and polyethylene oxide; a water-soluble polymer derived from acrylic acid; medicament; and plasticizer. The compositions provide an effective medicament delivery system and are especially suitable for use with adhesive bandages.

Abstract: This invention relates to a composition containing a hydrophobic solvent, a network polymer and a flow control agent which is useful in healing wounds. The composition of this invention may be applied directly to a wound to create a structured occlusive dressing. The dressings of this invention do not migrate, but maintain their integrity at skin temperature, and encourage the creation of a moist wound environment while protecting the wound in order to accelerate healing.

Abstract: New media have been developed for china paints useful for painting or decorating porcelain bisque, ceramic and stoneware articles. These media, consisting of low surface tension glycols and water soluble polymers, enable the artisan to paint non-blotching surfaces, fine lines and details and multiple layers without a separate kiln firing between layers.

Abstract: A stable and clear aqueous solution of zinc salt useful as a mouthrinse and a gel dentifrice. In a preferred embodiment the aqueous solution comprises zinc chloride codissolved with a complexing agent of sodium gluconate, in a naturally derived anionic polymer of sodium carboxymethylcellulose. This solution is advantageous because it maintains clarity and chemical stability in temperatures of from about 4.degree. to about 50.degree. C. and may be alcohol-free. The anionic polymer acts as a buffer to provide a solution with a pH in a desirable range of from about 5.7 to about 6.5, which limits astringency and tartness.

Abstract: A bioadhesive extruded single or multi-layered thin film, especially useful in intra-oral controlled-releasing delivery, having a water soluble or swellable polymer matrix bioadhesive layer which can adhere to a wet mucous surface and which bioadhesive layer consists essentially of 40-95% by weight of a hydroxypropyl cellulose, 5-60% of a homopolymer of ethylene oxide, 0-10% of a water-insoluble polymer such as ethyl cellulose, propyl cellulose, polyethylene and polypropylene, and 2-10% of a plasticizer, said film having incorporated therein a medicament, e.g., anesthetics, analgesics, anticaries agents, anti-inflammatories, antihistamines, antibiotics, antibacterials, fungistats, etc.
