Abstract

The present invention relates to a solid block comprising a solidified material, characterized in that the solid block comprises one or more domains of prismatic or cylindrical shape extending between two parallel surfaces of the solid block from one surface to the other, wherein the solidified powder inside the one or more domains and the solidified powder outside the one or more domains each comprises one or more chemical substances, and wherein the chemical composition of the solidified powder inside the one or more domains is different from the chemical composition of the solidified powder outside the one or more domains. The present invention further relates to methods for producing such solid block. The present invention also relates to the use of such solid block as detergent in warewashing applications.
