Abstract:
New contact lens cleaning materials are designed for use in cleaning fluorine and silicon containing hard contact lenses. The contact lens cleaning materials are water based and contain an alkylphenyl polyether alcohol surfactant, an anionic second surfactant selected to have good cleaning action with respect to protein and mucous-like material deposits and a phosphate ester surfactant.
