ABSTRACT:
The invention relates to a toothpaste which contains a mixture of an alkalimetal trimetaphosphate and a fluoride salt as anti-caries agents. The interaction between the trimetaphosphate salt and the fluoride salt is substantially reduced by providing the trimetaphosphate salt to be present in the liquid phase of the toothpaste in at least partly insoluble form. Optimum results are obtained if all the trimetaphosphate is present in insoluble form in the liquid phase.
