Abstract

Abstract An antibacterial oral composition effective to promote oral hygiene containing an antibacterial antiplaque agent and an additive which reduces staining of dental surfaces 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 antistain additive is a polymeric polyphosphonic compound, such as polyallyl bis-(phosphonomethylene) amine acid and salts thereof.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 107 words
An oral composition comprising an oral vehicle, a nitrogen containing antibacterial antiplaque agent tending to stain dental surfaces selected from the group consisting of cationic antibacterial antiplaque agent and long chain amine antibacterial antiplaque agent containing a fatty alkyl group of 12 to 18 carbon atoms and a water soluble polymeric polyphosphonic compound antistain additive having the recurring group: ##STR15## wherein X is selected from the group consisting of hydrogen and an orally acceptably action and Y is selected from the group consisting of hydrogen and CH 3 , and the unphosphonated recurring groups of said compound have a total molecular weight of at least about 3,500.
Claim 2
Dependent Claim 107 words
An oral composition comprising an oral vehicle, a nitrogen containing antibacterial antiplaque agent tending to stain dental surfaces selected from the group consisting of cationic antibacterial antiplaque agent and long chain amine antibacterial antiplaque agent containing a fatty alkyl group of 12 to 18 carbon atoms and a water soluble polymeric polyphosphonic compound antistain additive having the recurring group: ##STR15## wherein X is selected from the group consisting of hydrogen and an orally acceptably action and Y is selected from the group consisting of hydrogen and CH 3 , and the unphosphonated recurring groups of said compound have a total molecular weight of at least about 3,500.
Claim 3
Dependent Claim 31 words
