Abstract: The invention relates to a method for reducing microbial infestation of an aqueous technical product, comprising the steps: (a) providing an aqueous technical product, for example a dye, having a pH in the range of 7.0-9.5 and containing: i. 25-100 ppm 5-chloro-2-methyl-4-isothiazolone (CMIT) and ii. 50-1000 ppm of one or more zinc compound(s), selected from the group consisting of zinc oxide, zinc carbonate, zinc hydroxide and zinc hydroxycarbonate; (b) breaking down some of the CMIT by adding at least one pyrithione compound selected from sodium pyrithione, potassium pyrithione and calcium pyrithione, in a total amount in the range of 25-500 ppm so that the concentration of the CMIT in the technical product is in the range of 5-15 ppm; and (c) storing the technical product over a period of up to 9 months.

Abstract: The present invention relates to a microbicidal composition in the form of a concentrate and to the use of the composition for the preservation of technical and domestic products, preferred for the preservation of wet wipes.
