Abstract: Concentrated solutions of biocides are provided, particularly for silicone caulks, which comprise a biocide, sufficient levels of a ketoxime as a solvent for the biocide, and optional non-volatile carrier liquid.

Abstract: A liquid concentrate comprises between about 4 and about 25 wt % of 4,5-dichloro-2-(n-octyl-4-isothiazolin-3-one), between about 25 and about 88 wt % of a plasticizer in which said isothiazolinone compound is soluble and between about 8 and about 50 wt % of benzyl alcohol which stabilizes the concentrate against crystallization and/or freezing at sub-freezing conditions.

Abstract: Composition of an antimicrobial agent and an antioxidant having improved antimicrobial activity compared to the antimicrobial agent alone. The preferred environment of the invention is a composition of a thermoplastic resin, an antioxidant, and an antimicrobial agent, the latter two being compatible with the resin. The resin composition can contain other usual additives, and can be melt processed at an elevated temperature to form articles such as films or fibers having improved antimicrobial activity. A method for improving the efficacy of an antimicrobial agent by combining it with an antioxidant is disclosed. A method for melt-processing a resin composition containing an antimicrobial material is also disclosed, wherein the resin composition includes an antioxidant.

Abstract: The use of a bath containing the same antimicrobial agent as that previously incorporated in a fiber permits the antimicrobial concentration in the fiber to be controlled when the fiber is processed through liquid media such as dye baths and the like.

Abstract: A lower temperature technique for incorporating antimicrobial agents into fibers following the melt step in fiber manufacturing processes results in several advantages when contrasted with incorporation during the molten state.

Abstract: Organometallic compounds, such as 10, 10'-oxybisphenoxarsine, are removed from aqueous media by preferential absorption onto solid polyamide absorbents, such as Nylon, in the form of pellets, fibers, granules, film or coatings.
