Cleaning manner null of liquid agent composition and hydrous Characteristic contact lens for hydrous Characteristic contact lens

摘要

PURPOSE: To prevent the osmic pressure of a soln. having a low osmotic pressure from being far from a physiological level when the soln. is diluted at the time of washing a contact lens by forming the soln. in such a manner that the activity of protease can be stably maintained in the soln. ;CONSTITUTION: Glycerol is incorporated at 5 to 40wt.% (w/v) and boric acid and/or borate at 4 to 20% (w/v) into the soln. contg. an effective ratio of the protease at such ratios at which the content of the boric acid and/or borate attains 10 to 100 pts.wt. per 100 pts.wt. glycerol.;COPYRIGHT: (C)1993,JPO&Japio
