Abstract

Peroxy-containing concentrates, stable in storage, useful for the production of functional agents consisting essentially of

0.5% to 20% by weight of peracetic or perpropionic acid or their precursors,

25% to 40% by weight of H₂ O₂

0 to 5% by weight of anionic surface-active compounds of the sulfonate and sulfate type,

Remainder: water.

Claims

1. A peroxy-containing concentrate, stable in storage, consisting essentially offrom 0.5% to 20% by weight of an acid selected from the group consisting of peracetic acid, acetic acid, perpropionic acid, propionic acid, mixtures of peracetic acid and acetic acid, and mixtures of perpropionic acid and propionic acid,from 25% to 40% by weight of H₂ O₂,

3. The peroxy-containing concentrate of claim 1 wherein component (1) is present in an amount of from 5% to 10% by weight, and said H₂ O₂ of component (2) is present in a molar excess with reference to said acid of component (1), calculated as the monocarboxylic acid of a molar ratio of at least 2:

1.

5. The peroxy-containing concentrate of claim 3 wherein said component (3) is present in an amount of from 0.5% to 5% by weight.

7. The peroxy-containing concentrate of claim 1 wherein said component (3) is present in an amount of from 0.5% to 5% by weight.

2. from 0 to 5% by weight of an anionic surface-active compound selected from the group consisting of sulfonates and sulfates, andthe remainder to 100% by weight, water.

4. The peroxy-containing concentrate of claim 2 wherein said molar ratio of H₂ O₂ to monocarboxylic acid is from 3:

1 to 50;

1.

6. The peroxy-containing concentrate of claim 4 wherein said anionic surface-active compound is selected from the group consisting of alkylbenzene sulfonates having from 6 to 18 carbon atoms in the alkyl, alkane sulfonates having from 8 to 22 carbon atoms in the alkane, and alkyl sulfates having from 8 to 22 carbon atoms in the alkyl.

8. The peroxy-containing concentrate of claim 6 wherein said anionic surface-active compound is selected from the group consisting of alkylbenzene sulfonates having from 6 to 18 carbon atoms in the alkyl, alkane sulfonates having from 8 to 22 carbon atoms in the alkane, and alkyl sulfates having from 8 to 22 carbon atoms in the alkyl.
