Abstract

The invention relates to compositions, methods of use, and methods of manufacture for an intercalated bleach compound and compositions thereof. The intercalated bleach compound has the formula Mx(OCl)y(O)m(OH)n where M is an alkaline earth metal such as magnesium, calcium or mixture thereof. The values of x and y independently equal any number greater than or equal to 1 (e.g., 1, 2, 3, 4, etc.), and m and n independently equal any number greater than or equal to 0 (e.g., 0, 1, 2, 3, 4, etc.), but m and n are not both 0. In addition, the molar ratio of the alkaline earth metal (e.g., magnesium or calcium) to hypochlorite is at least 3:1. In other words, x is ≥3y. The compounds exhibit excellent stability, little or no chlorine bleach odor, exhibit excellent pH buffering characteristics, and less reactivity with organic materials as compared to alternative chlorine bleach products.

First claim

The invention claimed is:

1. A composition comprising:
a bleach compound having the formula:
M x (OCl) y (O) m (OH) n
wherein M is at least one of magnesium or calcium and optionally, at least one additional alkaline earth metal;
wherein x and y independently are any number greater than or equal to 1;
wherein m and n independently are any number greater than or equal to 0, but m and n are not both 0;
wherein x is ≥3y; and

wherein the composition is employed for odor control.

2. The composition of claim 1 , further comprising at least one of: a builder, a surfactant, a water soluble polymer, an acid, a filler, a diluent, a desiccant, a buffer, a solid processing aid, a preservative, a colorant, an anti-corrosion inhibitor, a dye, a fragrance, a hydrotrope, a polymer dispersant, a chelating agent, a water-swellable polymer, a disinfectant, an antimicrobial, an essential oil, or an enzyme.

3. The composition of claim 1 , wherein M is a magnesium.

4. The composition of claim 1 , wherein the composition may be attached to or embedded in a substrate.

5. The composition of claim 1 , wherein the composition may be embedded or integrated into a plastic film.

6. The composition of claim 1 , wherein the composition may be embedded or integrated into a polymer film.

7. The composition of claim 1 , wherein x=0.5y+m+0.5n.

8. The composition of claim 1 , wherein x, y, m, and n are integers.

9. A composition comprising:
a bleach compound having the formula:
M x (OCl) y (O) m (OH) n
wherein M is at least one of magnesium or calcium and optionally, at least one additional alkaline earth metal;
wherein x and y independently are any number greater than or equal to 1;
wherein m and n independently are any number greater than or equal to 0, but m and n are not both 0;
wherein x is ≥3y; and

wherein the composition is employed as an odor absorber, odor destroyer or odor deodorizer.

10. The composition of claim 9 , further comprising at least one of: a builder, a surfactant, a water soluble polymer, an acid, a filler, a diluent, a desiccant, a buffer, a solid processing aid, a preservative, a colorant, an anti-corrosion inhibitor, a dye, a fragrance, a hydrotrope, a polymer dispersant, a chelating agent, a water-swellable polymer, a disinfectant, an antimicrobial, an essential oil, or an enzyme.

11. The composition of claim 9 , wherein M is a magnesium.

12. The composition of claim 9 , wherein the composition may be attached to or embedded in a substrate.

13. The composition of claim 9 , wherein the composition may be embedded or integrated into a plastic film.

14. The composition of claim 9 , wherein the composition may be embedded or integrated into a polymer film.

15. A composition comprising:
a bleach compound having the formula:
M x (OCl) y (O) m (OH) n
wherein M is at least one of magnesium or calcium and optionally, at least one additional alkaline earth metal;
wherein x and y independently are any number greater than or equal to 1;
wherein m and n independently are any number greater than or equal to 0, but m and n are not both 0;
wherein x is ≥3y; and

wherein the composition is employed as an additive for animal litter for odor control.

16. The composition of claim 15 , wherein 2m+n≥5y.

17. The composition of claim 15 , wherein x=0.5y+m+0.5n.

18. The composition of claim 15 , wherein x, y, m, and n are integers.

19. The composition of claim 15 , wherein the bleach compound has a range of available chlorine from about 3% to about 25%.

20. The composition of claim 15 , further comprising at least one of: a builder, a surfactant, a water soluble polymer, an acid, a filler, a diluent, a desiccant, a buffer, a solid processing aid, a preservative, a colorant, an anti-corrosion inhibitor, a dye, a fragrance, a hydrotrope, a polymer dispersant, a chelating agent, a water-swellable polymer, a disinfectant, an antimicrobial, an essential oil, or an enzyme.
