Abstract
A chemical delivery product for delivering an oxidizing chemical into an aqueous system is disclosed. For instance, in one embodiment, a substrate containing an oxidizing chemical, such as trichloroisocyanuric acid, is coated with a water soluble polymer in order to prevent the oxidizing chemical from degrading prior to use and in order to facilitate handling. In accordance with the present disclosure, a neutralizing agent is contacted with the substrate in order to prevent the substrate from degrading the water soluble coating. In an alternative embodiment, a package is formed from a water soluble film forming composition combined with a base.
