Abstract

An aqueous hydrogen peroxide solution comprises a stabilizer chosen from the family of substituted or unsubstituted aminopolycarboxylic acids (APCA) or salts thereof. The solution may be used for disinfecting a packaging.

Claims (17)

1. An aqueous hydrogen peroxide solution consisting of:

from 20 to 98%, by weight of the solution, of hydrogen peroxide,

from 0.5 to 7 mg/kg, by weight of the solution, of a stabilizer,

wherein the stabilizer is chosen from the family of substituted or unsubstituted aminopolycarboxylic acids (APCA), or salts thereof, of general formula:

in which R and R′ are selected from group consisting of the following functional groups:

C1 to C3 alkyls, and

C1 to C3 carboxylic acids, and

the remainder to 100% of water.

2. The aqueous solution of claim 1 , comprising from 20 to 75%, by weight of the solution, of hydrogen peroxide.

3. The aqueous solution of claim 1 , wherein one of R or R′ consists of a methyl group and the other of R or R′ consists of a substituted or unsubstituted methanoic acid group or a salt thereof.

4. The aqueous solution of claim 1 , wherein one of R or R′ consists of a substituted or unsubstituted methanoic acid group or a salt thereof, and the other of R or R′ consists of a substituted or unsubstituted propanoic acid group or a salt thereof.

5. The aqueous solution of claim 1 , wherein the solution has a conductivity of 10 to 100 μS/cm.

6. The aqueous solution of claim 1 , wherein the solution has a maximum acidity of 1 mmol/kg.

7. The aqueous solution of claim 1 , wherein the solution has a content of dry residue at 110° C. of not more than 7 mg/kg.

8. The aqueous solution of claim 1 , wherein the loss of titer of said solution, measured according to the CEFIC-H 2 O 2 -AM-7161 method, is less than or equal to 5% relative to the initial concentration of hydrogen peroxide.

9. A process for disinfecting/sterilizing a product, comprising placing the product in contact with the aqueous solution of claim 1 .

10. The process of claim 9 , wherein the placing in contact is performed by spraying or vaporizing said solution onto said product.
