Dry, stable, high available halogen sanitizing granular compositions with a
rapid rate of dissolution comprising halogenated
1,3,5-triazine-2,4,6-triones and a dissolution accelerant that is an
alkali metal salt of 1,3,5-triazine-2,4,6-trione are disclosed. The
disclosed compositions may include inorganic and/or organic disintegration
agents. Additionally, these compositions may contain other performance
enhancing additives such as water clarifiers, algaestats/algaecides,
surfactants, glidants, processing aids, and binders. These UV stable
sanitizing compositions contain a high available halogen content, and are
stable even when stored in high-humidity environments.
