HYDROGEN PEROXIDE DESTROYING COMPOSITIONS AND METHODS OF USING SAME 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 peroxidecontaining liquid aqueous medium in response to the dissolving of the water soluble portion into the hydrogen peroxidecontaining liquid aqueous medium.
