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 H.sub.2 O.sub.2, 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.
Claims9
A stable peroxy-containing concentrate useful for the production of microbicidal agents consisting essentially of
- 1. from 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,
- 2. from 25% to 40% by weight of H.sub.2 0.sub.2,
- 3. 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,
- 4. from 0 to 5% by weight of an anionic surface-active compound selected from the group consisting of sulfonates and sulfates, and
- 5. the remainder to 100% by weight, water.
