COMPOSITION FOR ORAL CARE Russian patent published in 2022 - IPC A61K8/81 A61Q11/00 

FIELD: personal hygiene.

SUBSTANCE: invention relates to a composition for oral care for inhibition of teeth demineralization. The proposed composition contains a carrier acceptable for oral administration and cationic copolymer with repeated links obtained from n-vinylpyrrolidone (VP) and repeated links obtained from monomers containing amines or guanidine, selected from a group consisting of n-vinyl phthalimide, 2-N-morpholinoethylacrylate, 2-N-morpholinoethylmethacrylate, 2-diisopropylaminoethylmethacrylate, 2-aminoethylmethacrylate, methacryloyl-L-lysine, N-(2-aminoethyl)methacrylamide, 2-(tert-butylamino)ethyl methacrylate, 2-acryloxyethyltrimethylammonium, 3-guanidinopropylmethacrylate, N-(3-guanidinopropyl)methacrylamide, arginine methacrylamide, N-(diaminomethylene)-2-methylprop-2-enamide, 1-(2-aminoethyl)-1H-pyrrole-2,5-dione and 1-(2-(2,5-dioxo-2,5-dihydro-1H-pyrrole-1-yl)ethyl)guanidine, spermidine and 1-(4-aminobutyl) guanidine.

EFFECT: use of the above-mentioned cationic copolymers of vinylpyrrolidone in compositions for oral care allows for achievement of useful effects of demineralization prevention.
