Abstract: A process is provided to produce a concentrated aqueous peracid solution in situ using at least one enzyme having perhydrolase activity in the presence of hydrogen peroxide (at a concentration of at least 500 mM) under neutral to acidic reaction conditions from suitable carboxylic acid esters (including glycerides) and/or amides substrates. The concentrated peracid solution produced is sufficient for use in a variety of disinfection and/or bleaching applications.

Abstract: A tableted biocidal/virucidal composition comprising (a) 0.01 to 5 parts by weight of a water soluble inorganic halide, (b) 25 to 60 parts by weight of an oxidizing agent, (c) 3 to 8 parts by weight of sulfamic acid, (d) up to about 10 parts by weight of an anhydrous alkali metal phosphate, (e) 5 to 25 parts by weight of a water-soluble carbonate or bicarbonate, and (f) a non-reducing organic acid in an amount sufficient that the pH of a 1% by weight aqueous solution of the composition is between 1.5 and 3.5; the parts by weight of the composition totaling 100, wherein a 5 gram tablet of the composition dissolves in 500 ml of water in less than 8 minutes at ambient temperature. Solutions of the composition in tablet form dissolved in a polar solvent provide a liquid disinfecting agent that is useful in sanitizing hard surfaces.
