ORAL CARE COMPOSITIONS WHICH COMPRISE STANNOUS AND POTASSIUM.

摘要

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; c. a chelant; d. a fluoride ion source; e. less than 0.01% of an alkyl sulphate or an alkyl ethoxylate sulphate; and f. a surfactant selected from a cationic, an amphoteric surfactant, a nonionic surfactant or mixtures thereof; 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.
