Abstract (en)
[origin: WO9112826A1] A composition and method of using such compositions to destroy hydrogen peroxide in a liquid aqueous medium, such as that used to disinfect 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 includes material capable of at least partially dissolving in an aqueous medium having a pH in the range of 5.1 to 6.9 by forming one or more soluble salts of the material.
