(KR101644795) Methods of inhibiting the uptake of cationic biocides into medical devices such as contact lenses and implants are described. Methods of stabilizing emulsions containing cationic biocides are also described. In particular, the present invention provides for the use of polymers acting as labile anionic polyelectrolytes to reversibly bind cationic biocides. The reversible binding can reduce the deleterious effects of cationic biocides while maintaining biocidal activity. Preferred polymers include galactomannan and polyvinyl alcohol. (From US9040510 B2)
(KR101644795) 1. The positive ion biocide and step rate as for under containing the cis - Dior - containing Polymer as for under adding the thing the low of including the cis - Dior - containing Polymer is about under using to the composition, as the method which within with the draw gel biomass suppresses the absorption of the positive ion biocide the method which a contact lens or an implant, the minute description biomass is. 2. There is in a 1st claim, and ph of the composition 7 as for under exceeding the method which is a thing. 3. Is in the 1st claim or the second claim, and the method where the positive ion biocide is the Polymer 4 class ammonium chemical compound. 4. There is in a 3rd claim, and the Polymer 4 class ammonium chemical compound pulley quota [nyum] - the method which is 1. 5. There was in a 1st claim, and the cis - Dior Polymer met the polyvinyl alcohol and the lacto which will go (galactomannan) as for under including from the army the method which is chosen. 6. Will be in the fifth claim, the lacto which will go this nine sword which met (guar gum) and the Locust bean sword (locust bean gum), burn from the army which is composed with the sword (tara gum) and these chemical variation derivative the method which is chosen. 7. There is in a fifth claim, and the lacto which will go this hydroxy profile nine which met as for under including the method which is a thing. 8. There was in a fifth claim, and the composition puts out the lacto which will go met the quantity 0.01 to 1 weight/bulk % the method.
