ABSTRACT:
A dental composition, such as a paste or gel dentifrice containing triclosan, as an antibacterial agent which acts to decrease plaque on the teeth, is packaged in a hand holdable and squeezable dispensing container which is made of or includes a part or parts of a solid polymeric material, such as a polyfluoroethylene or polyvinyl chloride, which is compatible with triclosan, so that excessive loss of its anti-plaque activity on storage is avoided, which losses have been noted when various other plastics have been employed as dispensing container component materials. Alternatively, other more reactive plastics may be employed for such dispensing container parts when a stabilizer, such as terpene, e.g., limonene, is present in the dentifrice. The dentifrice preferably also contains an anti-tartar proportion of polyphosphate, a tooth hardening proportion of a source of fluoride ions, a stabilizing proportion (in conjunction with the fluoride source) for the polyphosphate, of a polyvinyl methyl ether/maleic anhydride copolymer, and normal dentifrice components and adjuvants.
