ABSTRACT:
There are provided shelf stable liquid concentrates for dilution to form dental rinse compositions for loosening and removing plaque present on dental surfaces, while reducing the level of plaque forming bacteria present in the oral cavity consisting essentially of an aqueous or an aqueous and alcoholic carrier for the ingredients of said concentrate, wherein the ingredients include about 0.1% to about 10% by weight of said concentrate of an oral surfactant, suitably an anionic surfactant, at least about 1% by weight of said concentrate of sodium benzoate, and sufficient pharmaceutically acceptable acid to maintain the pH of said concentrate in the range of about 6.2 to about 5.6. These concentrates, in order to be used, are diluted to form dental rinse compositions, with water, in the ratio of between about 1 to about 15 parts by weight of water to 1 part by weight of concentrate, resulting in a pH in the range of about 6.0 to about 4.7. There is also provided a method of loosening and removing plaque present on dental surfaces, while reducing the level of plaque forming bacteria present in the oral cavity comprising the step of rinsing the oral cavity with such a composition.
