Предлагаемая композиция применяется для разложения перекиси водорода в жидкой водной среде, а также для дезинфекции контактных линз. Композиция включает по крайней мере один элемент, содержащий компонент для разложения перекиси водорода, например каталазу, влияющий на разложение перекиси водорода при выделении в жидкой водной среде или вызывающий разрушение присутствующей в жидкой водной среде перекиси водорода, и защитное покрытие, нанесенное поверх и служащее для предотвращения выделения компонента, разлагающего перекись водорода при первом контакте композиции с жидкой водной средой, содержащей перекись водорода. Защитное покрытие включает растворимый в воде компонент, например оксипропилметилцеллюлозу. Покрытие получают способом с применением смеси, содержащее воду, кетон и растворимый в воде компонент, наносят по крайней мере один слой и удаляя воду и кетон из нанесенного ранее слоя или слоев. В предпочтительном варианте композиция включает очищающий фермент для удаления инородных веществ с контактных линз, в частном случае - при одновременной дезинфекции линз.The proposed composition is used for the decomposition of hydrogen peroxide in a liquid aqueous medium, as well as for disinfection of contact lenses. The composition includes at least one element containing a component for the decomposition of hydrogen peroxide, such as catalase, affecting the decomposition of hydrogen peroxide when released in a liquid aqueous medium or causing the hydrogen peroxide present in a liquid aqueous medium, and a protective coating applied over the surface the selection component, decomposing hydrogen peroxide at the first contact of the composition with a liquid aqueous medium containing hydrogen peroxide. The protective coating includes a water soluble component, for example hydroxypropyl methylcellulose. The coating is prepared by a method using a mixture containing water, ketone and a water-soluble component, at least one layer is applied and the water and ketone are removed from the previously applied layer or layers. In a preferred embodiment, the composition comprises a cleansing enzyme to remove foreign substances from contact lenses, in a particular case with simultaneous disinfection of the lenses.
