ORAL COMPOSITION Russian patent published in 2019 - IPC A61K8/55 A61K8/21 A61K8/24 A61Q11/00 

FIELD: hygiene.

SUBSTANCE: group of inventions relates to an oral composition and use thereof. Disclosed oral composition contains the following components (A) and (B): (A) is phytic acid or its alkali metal salt in amount of 0.04 wt. % to 1 wt. % in terms of phytic acid; (B) is monofluorophosphoric acid or its alkali metal salt in amount of 500 ppm up to 1,500 ppm in terms of fluorine atoms, wherein weight ratio of component (A) to component (B), ((A)/(B)) ranges from 0.1 to 1.4; pH of the composition ranges from 5.5 to 6.5. Composition does not contain or contains a compound which provides fluorine ions, (F), selected from a group consisting of sodium fluoride, potassium fluoride and ammonium fluoride, in amount of 100 ppm or less in terms of fluorine atoms; does not contain or contains a polyvalent metal cation in an amount less than 0.1-fold in terms of moles relative to component (A); does not contain or contains polyphosphoric acid or its salt in amount of 20 wt. % or less in terms of acid relative to component (A). Disclosed also is use of said composition for fluoride tooth absorption with inhibition of plaque formation on teeth, and use for tooth fluoride absorption with inhibition of plaque formation on teeth and glossy teeth.

EFFECT: combination of components of composition enables to effectively inhibit formation of staining on dental surface, intensifying teeth whitening effect and effect, giving dental shine, and can also increase fluoride tooth absorption degree, providing effective inclusion of fluoride in enamel or dentin, and effectively weaken binding substance, which is result of application of phytic acid.
