摘要：
Methods of inhibiting theuptake of cationic biocides into medicaldevices such as contact lenses andim-plants are described. Methods ofstabi-lizing emulsions containing cationicbio-cides are also described. In particular,the present invention provides for theuse of polymers acting as labile anionicpolyelectrolytes to reversibly bindcationic biocides. The reversible bindingcan reduce the deleterious effects ofcationic biocides while maintainingbio-cidal activity. Preferred polymersin-clude galactomannan and polyvinylalco-hol.
