ORAL COMPOSITIONS CONTAINING STANNOUS

摘要

Oral care compositions having improved efficacy for preventing and/or reducing caries, containing: from about 0.001% to about 5%, of metal ions wherein the composition comprises at least about 0.001%, of stannous ions and optionally comprises from about 0.001% to about 4%, of zinc ions; at least about 100ppm, by weight of the composition, of fluoride ions; at least about 0.03%, by weight of the composition, of a mineral surface active agent selected from homopolymers of itaconic acid, homopolymers of acrylic acid, copolymers of maleic acid and acrylic acid, copolymers of maleic anhydride or acid with methyl vinyl ether, and mixtures thereof; at least 5%, of water; less than 10%, by weight of the composition, of fused silica, calcium based abrasives, and mixtures thereof; less than 5%, of polyphosphates having n+3 or higher; wherein the weight ratio of total metal ion to the mineral surface active agent is equal to or less than 0.5.
