Abstract
A toothpaste composition containing an effective amount of cetylpyridinium chloride and a mixture of toothpaste forming ingredients including at least one amphoteric surfactant and optionally at least one sweetener.
Claims12
A toothpaste composition comprising:
- a) the absence of an anionic sweetener;
- b) an antibacterial effective amount of cetylpyridinium chloride;
- c) a mixture of toothpaste forming components other than cetylpyridinium chloride, including active components, passive components, or both, at least one of which is anionic, at least one amphoteric surfactant and at least one sweetener selected from the group consisting of cationic, non-ionic and amphoteric sweeteners, whereby in the absence of the amphoteric surfactant, the anionic toothpaste forming components would bind to the cetylpyridinium chloride preventing it from being attracted to negatively charged tooth surfaces, and because of the presence of the amphoteric surfactant the cetylpyridinium chloride is able to effectively bind to the negatively charged tooth surfaces.
