  • Patent number: 9314410
    Abstract: An oral care composition comprising a stannous ion source and/or a zinc ion source; a phytic acid or a phytic acid salt or mixtures thereof; characterized in that the phytic acid or phytic acid salt has an average IPn of greater than 5.2. In a composition which comprises stannous, there is a decrease in soluble stannous whilst maintaining an equivalent efficacy to a composition comprising a higher level of soluble stannous and efficacy is observed for avoiding stain and astringency problems. When zinc ions are present, it has been surprisingly found that a decrease in soluble zinc can provide an equivalent antimicrobial efficacy to a composition comprising a greater level of soluble zinc.
