FIELD: hygiene.

SUBSTANCE: group of inventions relates to the field of oral care products and methods for preparing them. Disclosed is an oral care product containing an oral care composition comprising: an effective amount of a soluble sulphate acceptable for oral use, and a buffered electroconductive medium having pH of 4 to 6.5, where the persulphate is synthesized when the electric potential is applied to sulphate in a buffered electroconductive medium; and a cap having at least two electrodes electrically connected to a voltage source with an electrical potential of 1 to 5 V, wherein the electrodes include a cathode and an anode. Also disclosed is a method for preparing an oral care composition containing persulphate (S₂O₈^2-), which includes application of electric potentials difference from 1 to 5 V to an oral care composition containing a soluble usable sulphate for oral use in a buffered electroconductive medium having pH of 4 to 6.5.

EFFECT: group of inventions is suitable for use in situ persulphate (S₂O₈^2-), which can be used for teeth whitening, for oxidation of volatile sulphur-containing compounds which cause halitosis, or for elimination of bacteria on teeth.
