Abstract: The present invention relates to compositions having durable antimicrobial activity. The compositions include a carbonate/bicarbonate salt of a quaternary ammonium cation, an organic acid, hydrogen peroxide and a cationic polymer. The cationic polymer includes either a (3-acrylamidopropyl)trimethylammonium chloride monomer or a [2-(acrylolyoxy)ethyl]trimethylammonium chloride monomer. The cationic polymer also includes another monomer selected from a polar, water-soluble monomer, a hydrophobic, silicone-containing monomer or mixtures of both types of monomers in combination with one of the trimethylammonium chloride monomers.

Abstract: Water Resistant Film Forming Compositions Incorporating Hydrophilic Activities A film forming composition that includes a polymer having from about 80 mole percent to about 100 mole percent of a hydrophobic component, and from about 0 to about 20 mole percent of a charged component; a bioactive agent; and a solvent in which the polymer and the bioactive agent are homogeneously dispersed in the composition. The film forming composition can be used as a “liquid bandage” to form a water resistant film on a biological surface, where the polymer and the bioactive agent remain miscible.

Abstract: Computer-implemented methods, programs and apparatus for generating a library design for a combinatorial library of materials. A library design includes a set of sources representing components to be used in preparing the combinatorial library, destinations replying arrangements of cells and mappings, defining one or more distribution patterns for assigning components to cells in the destination arrangement or arrangements. Mappings include gradients and sets of user-defined equations, and are used to calculate the amount of on components to be assigned to a cell or cells in an arrangement. A library design can also include one or more process parameters defined to vary over time or across a plurality of destination cells. The invention outputs a data file defining the library design, including electronic data representing the sources, the destinations and the mapping, in a format suitable for implementing manually or using automated material handling apparatus.
