PURPOSE:To obtain a compsn. for cleaning contact lens which decomposes away the org. contaminant of said lens by contg. mucin decomposition enzyme as an active component. CONSTITUTION:Mucin decomposition enzyme is prepd. by culturing species nova antinomycetes streptomyces hyalurolytics aseptically, filtering and concentrating the culture soln., adding a solvent thereto, refining the resulted precipitate and pulverizing the same by freeze drying and the preferable titer thereof is 5,000- 50,000 units/gr. The compsn. is required to contain an effective amt. of the mucin decomposition enzyme in order to remove the contaminant of contact lens, and the content thereof is preferably 0.1-5wt% in the case of a solid compsn, and 1X10<-3>wt%-5X10<-2>wt% in the case of a compsn. in an aq. soln. The preferable compsn. contains the mucin decomposition enzyme, salt, sodium hydrogensulfite, 2-sodium ethylenediaminetetracetate, etc. and forms the aq. compsn. soln. isotonic to tears in the stage of cleaning. |
