Abstract

Stabilized hydrogen peroxide-containing compositions and methods of making same are disclosed. The compositions contain a stabilizer system made up of a disulfonate surfactant, a diester solvent, and a sulfonic acid or a salt thereof in a sufficient quantity to provide the stabilized hydrogen peroxide with an acidic pH value. The compositions are suitable for use as disinfectants, as cleaning agents, and in various personal care applications such as hair care and tooth whitening.

Claims (15)

1. A stabilized hydrogen peroxide composition consisting of:

hydrogen peroxide;

a disulfonate surfactant;

a diester solvent;

a sulfonic acid in a sufficient quantity to provide the stabilized hydrogen peroxide with an acidic pH value;

water; and

optionally, one or a combination of an alcohol, a glycol ether, or an aliphatic phosphate ester.

2. The stabilized hydrogen peroxide composition of claim 1 , wherein the sulfonic acid is present in a quantity to provide a pH value in a range from about 1.5 to about 2.5.

3. The stabilized hydrogen peroxide composition of claim 1 , wherein the sulfonic acid is selected from the group consisting of a hydrocarbon sulfonic acid, a halohydrocarbon sulfonic acid, and combinations thereof.

4. The stabilized hydrogen peroxide composition of claim 1 , wherein the optional alcohol is present and said alcohol is ethanol or benzyl alcohol, or both.

5. The stabilized hydrogen peroxide composition of claim 1 , wherein the optional glycol ether is present.

6. The stabilized hydrogen peroxide composition of claim 1 , wherein the optional aliphatic phosphate ester is present.

7. The stabilized hydrogen peroxide composition of claim 1 , wherein the disulfonate surfactant includes an alkyldiphenyloxide disulfonate compound or a salt thereof.

8. The stabilized hydrogen peroxide composition of claim 1 , wherein the hydrogen peroxide is present in the composition in an amount in a range from about 0.5 wt % to about 10 wt %, and the sulfonic acid is present in a quantity to provide a pH value of about 3.5 or less.

9. The stabilized hydrogen peroxide composition of claim 1 , wherein at least one of the alcohol, the glycol ether, and the aliphatic phosphate ester is present.
