HYDROGEN PEROXIDE DESTROYING COMPOSITIONS AND METHODS OF USING SAME ABSTRACT OF DISCLOSURE A composition and method useful for destroying hydrogen peroxide in a liquid aqueous medium, such as that used to disinfect contact lenses, are disclosed. The composition comprises at least one hydrogen peroxide destroying component effective when released into a liquid aqueous medium to destroy or cause the destruction of hydrogen peroxide present in the liquid aqueous medium, and a barrier component acting to substantially prevent the release of the hydrogen peroxide destroying component for a period of time after the composition is initially contacted with a hydrogen peroxide-containing liquid aqueous medium. The barrier component includes a water soluble portion and a water insoluble portion. The hydrogen peroxide destroying component is situated so as to be released into the hydrogen peroxide- containing liquid aqueous medium in response to the dissolving of the water soluble portion into the hydrogen peroxide- containing liquid aqueous medium.
