1. A process for preparing a storage stable, clear concentrate of unlimited durability which, upon admixture with hydrogen peroxide, forms a disinfectant, comprising:

  • (a) admixing an inorganic acid with water, said water being selected from the group consisting of distilled water and fully desalted water, to yield aqueous inorganic acid having a pH less than or equal to 1.6;

    (b) admixing said aqueous acid at a temperature between 50 and 60°

    C. with a silver composition, selected from the group consisting of silver salts and silver salt complexes, in an amount which yields 95-105 g Ag per liter of the final concentrate;

    (c) cooling the resultant admixture to between 25 and 30°

    C., and adding such an amount of the same acid as was used for adjusting the pH of the water whereby the total amount of said acid is at least equimolar with the amount of silver present;

    (d) adding to said admixture an organic acid stabilizer, and optional gelatin, at 20 to 25°

    C.; and

    (e) homogenizing the obtained mixture.
