ABSTRACT:
Compositions, and methods for using such compositions, which are useful to destroy hydrogen peroxide in a liquid aqueous medium, such as that used to disinfect contact lenses. In one embodiment, the composition comprises a hydrogen peroxide destroying component effective when released in a hydrogen peroxide-containing liquid aqueous medium to destroy or cause the destruction of hydrogen peroxide present in the hydrogen peroxide-containing 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 the hydrogen peroxide-containing liquid aqueous medium, the barrier component comprising a material selected from the group consisting of water soluble cellulose derivatives and mixtures thereof having a molecular weight of at least about 20,000. The composition results in reduced foam formation relative to a similar composition including a barrier component comprising a similar material having a molecular weight of 10,000 when both the composition and the similar composition are exposed to identical hydrogen peroxide-containing liquid aqueous media to destroy or cause the destruction of the hydrogen peroxide therein.
