Title (EN) ORAL CARE COMPOSITIONS WHICH COMPRISE STANNOUS AND POTASSIUM SALTS
(FR) COMPOSITION POUR HYGIÈNE BUCCO-DENTAIRE RENFERMANT DE L'ÉTAIN ET DU POTASSIUM
Abstract: front page image
(EN)The present invention relates to a single phase oral care composition comprising: a. a stannous salt delivering a stannous ion; b. a potassium salt delivering a potassium ion wherein the potassium salt is selected from potassium nitrate, potassium gluconate, potassium citrate, potassium chloride, potassium tartrate, potassium bicarbonate, and mixtures thereof; c. a chelant; d. a fluoride ion source; and e. less than 0.01% of an alkyl sulphate or an alkyl ethoxylate sulphate; wherein the oral care composition provides a soluble fluoride ion level of greater than 50% of the total fluoride ion. The composition of the invention has been found to allow prolonged contact between stannous ion and nitrate ion in a single dentifrice without toxic effects or insoluble products. The invention further provides for the maintenance of an efficacious fluoride ion level.
(FR)Cette invention concerne une composition pour hygiène bucco-dentaire monophase comprenant : (a) un sel d'étain apportant un ion d'étain; (b) un sel de potassium apportant un ion de potassium, le sel de potassium étant pris parmi le nitrate de potassium, le gluconate de potassium, le citrate de potassium, le chlorure de potassium, le tartrate de potassium, le bicarbonate de potassium et des mélanges de ces composés; (c) un agent chélateur; (d) une source d'ion fluorure; et (e) moins de 0,01% d'un sulfate d'alkyle ou d' un sulfate d'alkyl éthoxylate. Cette composition pour hygiène bucco-dentaire à un niveau d'ion fluorure soluble supérieur à 50% de l'ion fluorure total. On a constaté que cette composition assurait un contact prolongé entre l'ion étain et l'ion nitrate dans un seul et même dentifrice sans effets toxiques ni présence de produits insolubles. Ladite composition de l'invention assure un maintien d'un niveau d'ion fluorure efficace.
