COMPOSITION IN FORM OF SOLUTION FOR CONTACT LENSES AND MEDICAL MATERIALS Russian patent published in 2016 - IPC A61L12/08 A01N31/16 A01N59/16 A01P1/00

Abstract RU 2581827 C2

FIELD: medicine, pharmaceutics.

SUBSTANCE: invention refers to the chemical-pharmaceutical industry and represents a composition in the form of a fluid containing a colloidal solution, for contact lens and medical material processing and care, and differing by the fact that it contains titanium dioxide particles TiO₂, having a size of less than 100 nm surface-modified by an organic compound specified in a group including: a) 4,5-dihydroxy-1,3-benzoldisulphonic acid disodium salt; b) ascorbic acid; and c) rutin. The invention provides creating a composition containing a nanocrystalline photocatalyst showing activity when exposed to visible light, which also can contain hydrogen peroxide.

EFFECT: composition preserves stability at pH ~ 7, and also improves sliding of the processed surfaces.
