Abstract
A chemical composition comprising a mixture of alkali and/or alkaline earth metal hypochlorites and, as a stabilizing and/or reinforcing agent, alkali and/or alkaline earth metal pyrosulfates.
Claims
exact text as granted — not AI-modifiedI claim:
1. A chemical composition consisting essentially of a mixture of (a) a member selected from the group consisting of an alkali metal pyrosulfate, an alkaline earth metal pyrosulfate or mixtures thereof.Iadd., .Iaddend..[.and.]. (b) a member selected from the group consisting of an alkali metal hypochlorite, an alkaline earth metal hypochlorite or mixtures thereof .Iadd.and (c) an agent rendering the pH of the chemical composition alkaline.Iaddend., component (a) being present in from about 1 to about 99 parts by weight.Iadd., .Iaddend..[.and.]. component (b) being present in from about 99 to 1 parts by weight.Iadd., and component (c) being present in an amount sufficient to render the pH of the composition in excess of 8.Iaddend..
