Abstract

The present invention relates to oral and dental care and cleaning agents comprising an aqueous dispersion of a phosphate-containing and/or phosphonate-containing polyurethane polymer and anionic surfactant(s), to tooth cleaning methods using these agents, and to the use of oral and dental care and cleaning agents comprising an aqueous dispersion of a phosphate-containing and/or phosphonate-containing polyurethane polymer and anionic surfactant(s) to reduce the restaining of teeth and/or to reduce biofilm development on dental surfaces and/or to reduce the adhesion of bacteria to dental surfaces and/or to extend the antibacterial action of antibacterial substances.

First claim

What is claimed is:

1. An oral and dental care and cleaning agent, comprising, based on the total weight thereof,
a) 1 to 20 wt. % of an aqueous dispersion of at least one phosphate-containing and/or phosphonate-containing polyurethane polymer, and
0.5 to 40 wt. % anionic surfactant(s), wherein the at least one phosphate-containing and/or phosphonate-containing polyurethane polymer comprises at least one polyurethane compound of formula (I), and at least one ionic polyether compound of formula (II), and at least one non-ionic polyether compound of formula (III), and at least one phosphate-containing and/or phosphonate-containing compound of formula (IVa) and/or (IVb) and/or (IVc)

where
R 1 and R 2 , each independently of one another, denote a linear or branched C 1 to C 4 alkyl group; a and b, each independently of one another, denote integers from 1 to 6;
X + denotes a physiologically compatible cation;
R 3 and R 4 , each independently of one another, denote hydrogen or a linear or branched C 1 to C 4 alkyl group, wherein at least one of the groups R 3 or R 4 denotes a linear or branched C 1 to C 4 alkyl group; e denotes integers from 1 to 15; and c and d, each independently of one another, denote integers from 10 to 60;
x denotes integers from 1 to 10; and
R 5 denotes a respective linear or branched C 1 to C 4 alkyl group.

2. The oral and dental care and cleaning agent according to claim 1 , wherein the at least one phosphate-containing and/or phosphonate-containing polyurethane polymer comprises at least one phosphonate-containing compound of formula (IVa-1) and/or (IVb-1) and/or (IVc-1)

3. The oral and dental care and cleaning agent according to claim 1 , wherein the at least one phosphate-containing and/or phosphonate-containing polyurethane polymer has a weight ratio of the at least one ionic polyether compound of formula (II), to the at least one non-ionic polyether compound of formula (III), of 2:1 to 1:5.

4. The oral and dental care and cleaning agent according to claim 3 , wherein the weight ratio of the at least one ionic polyether compound of formula (II), to the at least one non-ionic polyether compound of formula (III) is 2:1 to 1:3.

5. The oral and dental care and cleaning agent according to claim 1 , wherein the at least one phosphate-containing and/or phosphonate-containing polyurethane polymer includes at least one ionic polyether compound of formula (IIa)

and to the at least one non-ionic polyether compound of formula (IIIa)

and has a weight ratio of the at least one ionic polyether compound of formula (IIa), to the at least one non-ionic polyether compound of formula (IIIa) of 2:1 to 1:5.

6. The oral and dental care and cleaning agent according to claim 5 , wherein the weight ratio of the at least one ionic polyether compound of formula (IIa) to the at least one non-ionic polyether compound of formula (IIIa) is 2:1 to 1:2.

7. The oral and dental care and cleaning agent according to claim 1 , wherein the at least one phosphate-containing and/or phosphonate-containing polyurethane polymer additionally comprises at least one polyester compound, selected from the group consisting of: condensates of adipic acid with butylene glycol, condensates of azelaic acid with 1,6-hexanediol, and the mixtures thereof.

8. The oral and dental care and cleaning agent according claim 1 , wherein in that the phosphate-containing and/or phosphonate-containing polyurethane polymer has a phosphate content, based on the total weight thereof, of 0.005 to 3.0 wt. %.

9. The oral and dental care and cleaning agent according claim 1 , wherein in that the phosphate-containing and/or phosphonate-containing polyurethane polymer has a phosphate content, based on the total weight thereof, of 0.01 to 2.5 wt. %.

10. The oral and dental care and cleaning agent according claim 1 , wherein in that the phosphate-containing and/or phosphonate-containing polyurethane polymer has a phosphate content, based on the total weight thereof, of 0.05 to 2.0 wt. %.

11. The oral and dental care and cleaning agent according claim 1 , wherein in that the phosphate-containing and/or phosphonate-containing polyurethane polymer has a phosphate content, based on the total weight thereof, of 0.1 to 1.0 wt. %.

12. The oral and dental care and cleaning agent according claim 1 , wherein the at least one aqueous dispersion of at least one phosphate-containing and/or phosphonate-containing polyurethane polymer comprises 5.0 to 15 wt. % based on the total weight thereof of the cleaning agent.

13. The oral and dental care and cleaning agent according claim 1 , wherein the at least one aqueous dispersion of at least one phosphate-containing and/or phosphonate-containing polyurethane polymer comprises 8.0 to 11 wt. % based on the total weight thereof of the cleaning agent.

14. The oral and dental care and cleaning agent according to claim 1 , wherein the anionic surfactant(s) comprise 0.5 to 30 wt. % of the total weight thereof.

15. The oral and dental care and cleaning agent according to claim 1 , wherein the anionic surfactant(s) comprise 0.5 to 20 wt. % of the total weight thereof.

16. The oral and dental care and cleaning agent according to claim 1 , wherein the anionic surfactant(s) comprise 0.75 to 10 wt. % of the total weight thereof.

17. The oral and dental care and cleaning agent according to claim 1 , wherein the anionic surfactant(s) comprise 0.9 to 5.0 wt. % of the total weight thereof.

18. The oral and dental care and cleaning agent according to claim 1 , wherein the anionic surfactant(s) comprise 1.0 to 2.0 wt. % of the total weight thereof.
