  • Patent number: 4110429
    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 water soluble oligomer of the formula ##STR1## wherein M is a water soluble orally acceptable cation;R.sub.1, r.sub.2, r.sub.3 and R.sub.4 are independently H, methyl or ethyl;Y is at least one hydrophilic member of the group consisting of --COOM.sub.1, --CONH.sub.2, and --CH.sub.2 OH;X is at least one hydrophobic member of the group consisting of --CN, --COOR, --COOR.sub.5 OR, --CONHR, --COONHR.sub.5 COR, and --OOCR;M.sub.1 is H or M;R is C.sub.1-8 alkyl;R.sub.5 is C.sub.1-4 alkylene;a is 0-7; anda+b is about 4-15.
