Abstract

In accordance with this invention, there is provided an oral care composition comprising a multimodal blend of copolymers of maleic acid or maleic anhydride and an alkyl vinyl ether and a non-cationic antibacterial agent. The compositions feature improved retention of the antibacterial agent on teeth.

Claims (16)

1. An oral care composition comprising:

(a) a multimodal blend of copolymers of maleic acid or maleic anhydride and an alkyl vinyl ether; and

(b) a non-cationic antibacterial agent.

2. The oral care composition of claim 1 wherein said multimodal blend is a bimodal blend.

3. The oral care composition of claim 2 wherein said bimodal blend of copolymers have specific viscosities in the ranges of 2-10 and 0.1-2 respectively.

4. The oral care composition of claim 3 wherein said bimodal blend of copolymers have specific viscosities in the ranges of 2-6 and 0.1-1.75 respectively.

5. The oral care composition of claim 4 wherein said bimodal blend of copolymers have specific viscosities in the ranges of 2-4 and 0.1-1.5 respectively.

6. The oral care composition of claim 1 wherein said non-cationic antibacterial agent is triclosan.

7. The oral care composition of claim 1 wherein said alkyl vinyl ether is methyl vinyl ether.

8. The oral care composition of claim 2 wherein said copolymers are present in a weight ratio of 10:90 to 90:10.

9. The oral care composition of claim 8 wherein said copolymers are present in a weight ratio of 20:80 to 80:20.

10. The oral care composition of claim 8 wherein said copolymers are present in a weight ratio of 20:80 to 80:20.

11. An oral care composition comprising

(a) a bimodal blend of copolymers of maleic acid or maleic anhydride and an alkyl vinyl ether, said copolymers having specific viscosities in the ranges of 2-10 and 0.1-2 respectively and being present in a weight ratio of 10:90 to 90:10; and

(b) a non-cationic antibacterial agent wherein said composition exhibits improved retention of said agent on teeth.

12. A method of improving retention of a non-cationic antibacterial agent on teeth, said method comprising delivering said non-cationic antibacterial agent to said teeth in combination with a multimodal blend of copolymers of maleic acid or maleic anhydride and an alkyl vinyl ether.
