Abstract
An aqueous dentifrice composition comprising an aqueous vehicle containing at least two active ingredients reactive with each other, at least one of the active ingredients being encapsulated in a substantially water immiscible, pressure rupturable shell which is rupturable during use of the dentifrice, causing the same to be released for interaction with the other active ingredient, the shell being formed from a plasticized alkyl cellulose polymer. The dentifrice exhibits increased efficacy for fluoridation of teeth when the active ingredients are soluble fluoride salt and a calcium salt encapsulated in the plasticized alkyl cellulose polymer.
