FIELD: hygiene products.SUBSTANCE: invention relates to an oral care composition. Disclosed composition contains: a) a tin(II) ion source and a zinc ion source; b) phytic acid or salt of phytic acid or mixtures thereof, wherein said phytic acid or salt of phytic acid has average amount of phosphate groups on inosite (IPn) more than 5.2 and level of soluble tin(II) ion in supernatant when composition is diluted with water in ratio of 1:3 ranging from 200 to 6000 ppm. Use of commercial sources of phytic acid with (IPn) more than 5.2 provides higher bioavailability of tin and zinc ions and improved efficiency with respect to inhibiting dental deposit in comparison with similar compositions, including sources of phytic acid with low value (IPn), as well as improved control of colouring as compared to compositions with high content of tin.EFFECT: use of commercial sources of phytic acid with (IPn) provides higher bioavailability of tin and zinc ions and improved efficiency with respect to inhibiting dental deposit in comparison with similar compositions.14 cl, 4 dwg, 7 tbl, 7 ex |
