WASHING MATERIAL OF CONTACT LENS AND METHOD OF MANUFACTURING THE SAME

摘要

PURPOSE: To obtain a safe washing material for a hard contact lens by incorporating a specified anionic surfactant, an alkylphenyl polyether alcohol surfactant and an aq. suspending medium. CONSTITUTION: An anionic surfactant having satisfactory washing action to protein and viscous deposits as a 1st surfactant is mixed with an alkylphenyl polyether alcohol surfactant as a 2nd surfactant. These surfactants are suspended in an aq. suspending medium. The alkylphenyl polyether alcohol surfactant is preferably represented by formula I [where (x) is 3-12, preferably 9 or 10]. The objective safe washing material for a hard contact lens is obtd.
