LENS CARE SOLUTIONS FUNCTIONALIZED ALKYLDIMONIUM HYDROXYPROPYL ALKYLGLUCOSIDES
A contact lens care solution that includes a functionalized hydroxypropyl alkylglucoside. The functionalized hydroxypropyl alkylglucoside is typically in the form a mixture of various alkylglycosides because: (1) the functional reagents can react with any one or more of the many hydroxyl groups on the glycoside; and (2) the glycosides are present as a mixture of glycosides with a degree of polymerization from 1 to about 4. The solution will also include a buffer system to maintain the pH of the composition from 7.2 to 8.5. In particular, the solution can be formulated to clean and disinfect contact lenses or the solution is formulated as a rewet eye drop for use with contact lenses.
