1. A composition comprising:
(a) an aqueous preparation comprising at least one mineral comprising calcium carbonate, (b) one or more aldehyde-releasing and/or aldehyde-based biocides in an amount such that the total amount of aldehyde-releasing and/or aldehyde-based biocides in the aqueous preparation is from 250 ppm to 5000 ppm, calculated relative to the weight of water in the preparation, and (c) at least one source of a water soluble lithium compound in an amount such that the total amount of solubilized lithium in the aqueous preparation is from 1000 to 3000 ppm, calculated relative to the weight of water in the preparation, wherein the at least one water soluble lithium compound is selected from the group consisting of a polymeric lithium salt, Li2,Na2polyphosphate, lithium sodium hexametaphosphate, lithium polyacrylate, lithium carbonate, a lithium halide, lithium hydroxide, a lithium sulfate, lithium hydrogen sulfate, lithium citrate, and any mixture thereof. |
