Abstract
A composition that generates a target product and releases a biocidal solution containing the target product is presented. The composition comprises reactants capable of generating the target product through a chemical reaction, a halogen, and a gel-forming material. The chemical reaction is triggered when the reactants are contacted by a main solvent (e.g., water). The gel-forming material makes the composition stable for storage. Upon being exposed to the main solvent, the gel-forming material forms a gelatinous structure that creates a chamber within the composition enclosing some of the reactants such that the target product is generated in the chamber. The gelatinous structure contributes to the high yield of the target product (e.g., chlorine dioxide) and its controlled release. The halogen (e.g., bromine and/or chlorine) enhances the biocidal effect of the target product.
