Biphasic oral care compositions

Abstract:

This application provides, among other things, novel aqueous biphasic oral care compositions comprising two distinct aqueous phases, useful for combining and delivering poorly compatible ingredients, for example to deliver effective levels of cationic antibacterial agents in combination with anionic polymers, e.g. that protect against erosion and staining, by addition of a stabilizing amount of a polyamine, e.g. lysine, and methods for making and using the same.
