Abstract: This disclosure relates to inventive methods for inactivating viral pathogens comprising providing a virucidal composition comprising a liquid media containing less than 1% weight per volume of a quaternary ammonium compound, such as cetylpyridinium chloride and between 0% and 0.5% weight per volume of citric acid, and contacting a surface targeted for disinfection with the virucidal composition. This disclosure further relates to inventive virucidal compositions comprising a liquid media, a quaternary ammonium compound, such as cetylpyridinium chloride, at a concentration of less than 1% weight per volume, citric acid at a concentration of between 0.0% and 0.5% weight per volume, an extender, and an enhancer.

Abstract: An embodiment of the present invention includes a foam prepared from a resin comprising: one or more saccharides; one or more isocyanates; one or more resin polyols; and water. The foam may be for example polyurethane foam or polycyanurate foam, either flexible or rigid. Another embodiment includes a method for preparing a foam comprising: forming a resin by mixing one or more saccharides with one or more isocyanates and then mixing the one or more saccharides and the one or more isocyanates with water; and admixing one or more foam polyols to the resin. Another embodiment includes a method for manufacturing a foam derived from an isocyanate, comprising replacing all or a portion of the isocyanate with a resin comprising: one or more saccharides; one or more isocyanates; one or more resin polyols; and water. Another embodiment includes an article of manufacture comprising such foam.

Abstract: A novel resin for binding composite lignocellulosic, cellulosic and non-cellulosic products is disclosed. The resin is comprised of one or more isocyanates, one or more saccharides, one or more polyols, and water. Preferaby, the saccharide is a polysaccharide comprised of corn syrup. Preferably, the isocyanate is a polyisocyanate and the polyol is an ethylene glycol. Also disclosed are methods for preparing and applying the resin as well as the products prepared from the resin.

Abstract: A novel gypsum board having antifungal properties is disclosed. The board comprises a gypsum core, front and back paper facings and an antifungal agent effective at inhibiting fungal growth. A preferred antifungal agent is cetylpyridinium chloride. The antifungal agent can be present in the gypsum core and/or on one or both of the paper facings. In addition, the antifungal agent may be encapsulated in a material that releases the antifungal agent over time and/or upon exposure to moisture. Also disclosed are methods for preparing the aforementioned antifungal gypsum board.

Abstract: Particles of silica-rich plant material are bonded into a rigid unitary body. The silica content of such materials is believed to enter into bonding reactions when the materials are combined with a polymeric resin base material such as PAPI that has been previously converted by reaction with a colloidal gel formed from silica and a basic solution. The resulting product exhibits characteristics superior to most engineered wood products. A theoretical analysis of the bonding chemistry is proposed.

Abstract: An alkaline solution containing a complex of C.sub.30 H.sub.31 ClN.sub.6 is used as a specific indicator for detecting the presence of Candida spp. When Candida yeast bodies are introduced into the indicator solution, the yeast bodies are stained and form a blue or violet precipitate.

Abstract: Plant waste products high in cellulose and silica, i.e. rice hulls, are converted into a slurry of water and a silicate cross-linked cellulose polymer by digestion under heat and pressure in the presence of sodium ions and a sulfite. The slurry is treated with conventional foaming agents to form a formed product expanded in volume. The foamed product may be formed into any desired shape or size by extrusion, molding or casting.
