Abstract

Stable peroxy-containing concentrates useful for the production of microbicidal 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,

0.25% to 10% by weight of an organic phosphonic acid capable of sequestering bivalent metal cations and their water-soluble acid salts,

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

Remainder: water.

Claims

1. A stable peroxy-containing concentrate useful for the production of microbicidal agents consisting essentially offrom 0.5% to 20% by weight of an acid selected from the group consisting of peracetic acid, acetic acid, mixtures of peracetic acid and acetic acid, perpropionic acid, propionic acid and mixtures of perpropionic acid and propionic acid,from 25% to 40% by weight of H₂ 0₂,from 0.25% to 10% by weight of a sequestering compound selected from the group consisting of an organic phosphonic acid capable of sequestering bivalent metal cations and its water-soluble acid salt,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.

2. The stable peroxy-containing concentrate of claim 1 wherein component (1) is present in an amount of from 5% to 10% by weight, component (3) is present in an amount of from 0.5% to 5% by weight, and said H₂ 0₂ 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.

3. The stable peroxy-containing concentrate of claim 2 wherein said molar ratio of H₂ 0₂ to monocarboxylic acid is from 3:

1 to 50;

1.

4. The stable peroxy-containing concentrate of claim 3 wherein said component (4) is pesent in an amount of from 0.5% to 5% by weight.

5. The stable 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 carbons atoms in the alkyl.

6. The stable peroxy-containing concentrate of claim 1 wherein said component (4) is present in an amount of from 0.5% to 5% by weight.

7.
