Abstract
An antibacterial oral composition effective to promote oral hygiene containing an antibacterial antiplaque agent and an additive which reduces staining of dental surfaces caused by the antibacterial antiplaque agent without substantially diminishing the antibacterial and antiplaque activity of the agent. Bis-biguanido hexanes, such as chlorhexidine and alexidine, and quaternary ammonium salts, such as benzethonium chloride and cetyl pyridinium chloride, are typical examples of antibacterial agents. The stain reduction additive is a polyamine polyphosphonic compound, such as ethylenediamine tetra(methylene phosphonic acid) and salts thereof.
