发明名称 HYDROGEN PEROXIDE DESTROYING COMPOSITIONS AND METHODS OF MAKING AND USING SAME
摘要 A composition and methods useful for making such compositions and for using such compositions to destroy hydrogen peroxide in a liquid aqueous medium, such as that used to desinfect contact lenses, are disclosed. The composition comprises a coated core containing 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 coating 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 coating is substantially water soluble, preferably includes polyvinylpyrrolidone and is applied as a substantially dry, solid material.
