摘要

I.R. 4591 ANTIBACTERIAL ORAL COMPOSITION An antibacterial oral composition effective to promote oral hygiene containing an antibacterial antiplaque agent and an additive which substantially prevents staining of dental surfaces without substantially diminishing the antibacterial and antiplaque activity-of the agent. Bis-biguanides such as chlorhexidine and alexidine, and quaternary ammonium salts, such as benzethonium chloride and cetyl pyridinium chloride are typical examples of antibacterial agents. The antistain additive is an aminoguanidin free base or water soluble salt thereof compatible with the bis-biguanide or quaternary ammonium salt.
