Abstract
A composition of alkali carbonate peroxyhydrate in a quantity of 45 to 85% by weight relative to a total amount of the composition and an alkali hydrogen carbonate is provided for combating pathogenic germs and parasites in water of aquaculture, ponds, and aquariums; for destroying thread algae in water; for processing water. The addition of alkali hydrogen carbonate to alkali percarbonate peroxyhydrate stabilizes the alkali percarbonate peroxyhydrates relative to combustible materials. The alkali carbonate peroxyhydrate is preferably Na2CO3 and xH2O2.
Claims9
A composition consisting essentially of:
- an alkali carbonate peroxyhydrate in a quantity of 74 to 82% by weight relative to a total amount of the composition;
- and an alkali hydrogen carbonate as a stabilizer for the alkali carbonate peroxyhydrate;
- wherein the composition has an oxidizing effect that does not surpass that of Ba(NO3-)2:cellulose 7:3 when tested as set forth in European Union (EU) Regulation 67/548, part 2, and further wherein the ratio of alkali hydrogen carbonate to alkali carbonate peroxyhydrate is from 15:85 to 55:45.
A method of producing a composition comprising stabilized alkali percarbonate peroxyhydrate relative to combustible materials, the method comprising adding alkali hydrogen carbonate to alkali percarbonate peroxyhydrate in a ratio of alkali hydrogen carbonate to alkali carbonate peroxyhydrate of from 15:85 to 55:45, wherein the alkali percarbonate peroxyhydrate is stabilized such that it has an oxidizing effect that does not surpass that of Ba(NO3)2:cellulose 7:3 when tested as set forth in European Union (EU) Regulation 67/548, part 2, wherein the alkali carbonate peroxyhydrate is present in a quantity of 74% by weight to 82% by weight relative to the total amount of the composition.
