Fragrant monopersulfate compositions for water treatment and articles containing them
The invention relates to fragrant compositions for oxidizing organic compounds in pool or spa water, having an alkali metal monopersulfate, a fragrance, and an optional carrier, which do not have a multilayer tablet structure and which do not generate gas, fumes or significant heat on addition to water.
1 . A composition for oxidizing organic materials in water, comprising:
(a) an alkali metal monopersulfate;
(b) a fragrance;
wherein the composition is substantially free of carbonate, bicarbonate, and halide, salts, and wherein the composition does not contain a slow dissolving layer.
2 . The composition of claim 1 , wherein the fragrance is deposited or adhered to particles of the alkali metal monopersulfate.
3 . The composition of claim 1 , further comprising:
(c) a water-soluble or water-dispersible particulate carrier material for the fragrance.
4 . The composition of claim 3 , wherein the carrier material does not generate fumes when contacted with water and the alkali metal monopersulfate.
5 . The composition of claim 3 , wherein the carrier material does not react with, or form species reactive with, the fragrance.
6 . The composition of claim 3 , wherein the carrier is selected from the group consisting of a water-soluble alkaline earth metal sulfate, a water-soluble alkali metal borate, a water-soluble or water-dispersible organic polymeric material, and combinations thereof.
7 . The composition of claim 6 , wherein the water-soluble alkaline earth metal sulfate comprises magnesium sulfate.
8 . The composition of claim 6 , wherein the water-soluble alkali metal borate comprises sodium borate.
9 . The composition of claim 6 , wherein the water-soluble or water-dispersible organic polymeric material is selected from the group consisting of carboxymethylcellulose, hydroxypropylcellulose, polyacrylic acid, co-polyacrylic acid-acrylamide, and mixtures or blends thereof.
