Abstract
Abstract Germ-killing composition produced by contacting an acid material, preferably consisting of at least about 15% by weight of lactic acid, with sodium chlorite in aqueous media, the amount of acid being sufficient to lower the PH of the aqueous media to less than about 7. Methods of disinfecting and sanitizing include application of either the germ killing composition, or reactants providing in situ production thereof, to a germ carrier including substrates of various kinds as well as an enclosed air space.

Claim 1
Independent Claim
80 words
Process for the production of a composition having germicidal properties comprising contacting sodium chlorite with a substantially water soluble acid material selected from the group consisting of organic acids and mixtures thereof with inorganic acid, said acid material comprising at least about 15% by weight of lactic acid, and wherein said contacting is carried out in aqueous media and in the presence of sufficient of said acid to lower the PH of said aqueous media to less than about 7.
Claim 2
Dependent Claim
80 words
Process for the production of a composition having germicidal properties comprising contacting sodium chlorite with a substantially water soluble acid material selected from the group consisting of organic acids and mixtures thereof with inorganic acid, said acid material comprising at least about 15% by weight of lactic acid, and wherein said contacting is carried out in aqueous media and in the presence of sufficient of said acid to lower the PH of said aqueous media to less than about 7.
Claim 3
Dependent Claim
14 words
