Classification: A61L

Abstract:
A composition comprising 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 said hydrogen peroxide destroying component for a period of time after said composition is initially contacted with the hydrogen peroxide-containing liquid aqueous medium, said 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, said composition resulting 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 said composition and said similar composition are exposed to identical hydrogen peroxide-containing liquid aqueous media to destroy or cause the destruction of the hydrogen peroxide therein.
