PROBLEM TO BE SOLVED: To provide new foamable oral care compositions which reduce or prevent the formation of dental caries.SOLUTION: The present invention relates to foamable compositions comprising a physiologically acceptable salt of a basic amino acid, an acid source, and a soluble carbonate salt, wherein when the composition is dissolved in a solvent, e.g., water, carbon dioxide is released, and the amino acid salt is substantially solubilized. The soluble carbonate salt comprises, for example, potassium carbonate, potassium bicarbonate, sodium carbonate, and sodium bicarbonate. The compositions include solid foamable forms, such as tablets, powders and granulates, as well as foamable compositions comprising single tube non-aqueous or low water toothpastes and alternatively dual tube or sequestered compositions, where the acid and carbonate are kept separate until use. |
