(KR100976291) The use of nanoparticles of inorganic materials (e.g., synthetic smectite clays) in ophthalmic compositions is described. The nanoparticles are utilized as biologically inert carriers or depots for biocides. The nanoparticles are particularly useful in preventing or reducing the uptake of biocides from ophthalmic compositions by contact lenses, when the compositions are applied to the lenses.

(KR100976291) 1. The biocide as for under containing to the hydrogenous composition the weapon nano particle of effective quantity at the time of inclusion as for height the thing about under including, such composition at the time of application the height prevents the absorption of the biocide by the contact lens in case to the contact lens, at the time of reduction as for height as method, Minute description nano particle (a) 100nm under to particle size of 1nm excess; (b) 30 to 1000m (2)/g superficial. And (c) 6.0 to the method which keeps a whole sound surface charge from 7.8 phs. 2. The biocide and 0.000001 to 0.1 weight/capacity % (w/v%) to include the weapon nano particle, here nano particle (a) 100nm under to particle size of 1nm excess; (b) 30 to 1000m (2)/g superficial. And (c) 6.0 to the contact lens control composition which keeps a whole sound surface charge from 7.8 phs 3. There is in a 2nd clause, and in order for the composition to disinfect the contact lens the aqueous solution which is used being, the composition which does with feature. 4. Is in 3rd clause, the biocide at all, with nine no de being, the composition which features does. 5. Is in 4th clause, the biocide the amino at all, with nine no de being, the composition which features does. 6. There is in a 3rd clause, and the biocide is, 4 ammonium chemical compounds the composition which does with feature. 7. Is in 6th clause, 4 ammonium chemical compounds pulley quota [nyum] - does with 1 being, feature trillion sacred items. 9. The biocide and 0.000001 to 0.1 weight/capacity % (w/v%) to include the weapon nano particle, here nano particle (a) 100nm under to particle size of 1nm excess; (b) 30 to 1000m (2)/g superficial. And (c) 6.0 to the opthalmology medicine composition which keeps a whole sound surface charge from 7.8 phs.
