Peroxides and chlorine dioxide (compounds) can be stabilized for long periods of time (years) by combining the compounds with water that has been infused with dioxytetrahydride gas. Such stabilized materials can be used to infuse soft, solid substrates that can be used as sterile wipes, wound dressings, or the like.

Stabilized compositions employing a binding system for improving shelf stability of an activated bleach composition containing a peroxygen source and a catalyst activator are disclosed. Stabilized compositions employ a binding system comprising an anionic surfactant for a solid formulation of a catalyst activator and peroxygen source to provide shelf stability for an activated bleach composition. Methods of formulating and use are further disclosed.
