Abstract

Cleaning compositions functioning in a unique manner are described. These new compositions provide improved cleaning efficacy for all types of surfaces. In addition, in textile laundry applications these compositions provide superior cleaning efficacy for all types and colors of fabrics, as well as extending the range and types of stains and dirt that commonly can be treated by present day commercial laundry compositions.

Claims

1. A cleaning composition comprising a dry powder comprising a source of hydrogen peroxide and a solvent;

said composition having a pH of greater than about 8.75 when combined with water.

2. The composition of claim 1, further comprising sodium carbonate.

3. The composition of claim 1, wherein said hydrogen peroxide source comprises a member selected from the group consisting of sodium perborate tetrahydrate, sodium perborate monohydrate, sodium percarbonate monohydrate, sodium percarbonate tetrahydrate, an encapsulated form of sodium perborate tetrahydrate, an encapsulated form of sodium perborate monohydrate, an encapsulated form of sodium percarbonate monohydrate, an encapsulated form of sodium percarbonate tetrahydrate, and combinations thereof.

4. The composition of claim 1, wherein said solvent is selected from the group consisting of (a) solvents which are substantially immiscible in water, (b) solvents which are slightly immiscible in water, (c) solvents which are miscible in water, and combinations thereof.

5. The composition of claim 4, wherein said solvent is a combination of solvents including at least one solvent from (a) and at least one solvent from (b).

6. The composition of claim 4, wherein said solvent is a combination of solvents including at least one solvent from (a) and at least one solvent from (c).

7. The composition of claim 4, wherein said solvent is a combination of solvents including at least one solvent each selected from (a), (b), and (c).

8. The composition of claim 1, wherein said solvent is selected from the group consisting of terpenes, methylated plant oils, glycol ethers, C_1-12alcohols, C_1-12 ketones, C_1-12 esters, and combinations thereof.

9. A cleaning composition comprising a dry powder comprising a source of hydrogen peroxide and at least one solvent which is substantially immiscible in water;

said composition having a pH of greater than about 8.75 when combined with water.

10. A cleaning composition comprising a dry powder comprising:
