Abstract

A dentifrice containing sodium bicarbonate, a peroxide generator, and remineralizing calcium and phosphate salts is provided within an anhydrous vehicle to maintain stability and palatability.

Claims (36)

1 . A dentifrice composition comprising a mixture of sodium bicarbonate, a peroxide generator, at least one water soluble or partially water soluble calcium salt, and at least one water soluble phosphate salt, said mixture contained within an anhydrous vehicle.

2 . The composition of claim 1 wherein the peroxide generator is sodium percarbonate.

3 . The composition of claim 2 containing 10-65% by weight sodium bicarbonate and 1-10% by weight sodium percarbonate.

4 . The composition of claim 1 containing a partially water soluble calcium salt.

5 . The composition of claim 4 wherein said partially water soluble calcium salt is calcium sulfate.

6 . The composition of claim 4 containing 10-65% by weight sodium bicarbonate and 1-10% by weight sodium percarbonate.

7 . The composition of claim 6 containing 30-60% by weight sodium bicarbonate and 3-7% by weight sodium percarbonate.

8 . The composition of claim 1 wherein said vehicle comprises a polyethylene glycol humectant.

9 . The composition of claim 8 wherein said polyethylene glycol humectant comprises from about 20-75% by weight of said composition.

10 . The composition of claim 9 wherein said vehicle further contains a copolymer of polyethylene glycol and polypropylene glycol.

11 . The composition of claim 9 comprising 10-65% by weight sodium bicarbonate and 1-10% by weight sodium percarbonate.

12 . The composition of claim 11 containing a partially water soluble calcium salt.

13 . The composition of claim 12 wherein said partially water soluble calcium salt is calcium sulfate.

14 . The composition of claim 1 comprising 0.05-15% by weight each of said at least one calcium salt and phosphate salt.

15 . The composition of claim 14 wherein said phosphate salt is an alkali metal phosphate.

16 . The composition of claim 15 wherein said phosphate salt is dibasic potassium phosphate.

17 . A dentifrice composition comprising a first part containing a mixture of sodium bicarbonate, a peroxide generator, at least one water soluble or partially water soluble calcium salt, and at least one water soluble phosphate salt, said mixture contained within an anhydrous vehicle, and a second part comprising a fluoride salt contained within an aqueous vehicle, said first part and second part being physically separated from each other.

18 . The composition of claim 17 wherein said first and second parts are physically separated from each other in a dispenser which allows simultaneous dispensing of said first and second parts.

19 . The composition of claim 17 wherein said fluoride salt is sodium fluoride.

20 . The composition of claim 17 wherein the peroxide generator is sodium percarbonate.

21 . The composition of claim 20 wherein said first part contains 10-65% by weight sodium bicarbonate and 1-10% by weight sodium percarbonate.

22 . The composition of claim 17 wherein said first part contains a partially water soluble calcium salt.

23 . The composition of claim 22 wherein said partially water soluble calcium salt is calcium sulfate.

24 . The composition of claim 23 wherein said first part contains 10-65% by weight sodium bicarbonate and 1-10% by weight sodium percarbonate.

25 . The composition of claim 24 wherein said first part contains 30-60% by weight sodium bicarbonate and 3-7% by weight sodium percarbonate.

26 . The composition of claim 17 wherein said anhydrous vehicle comprises a polyethylene glycol humectant.

27 . The composition of claim 26 wherein said polyethylene glycol humectant comprises from about 20-75% by weight of said first part of said composition.

28 . The composition of claim 26 wherein said anhydrous vehicle further contains a copolymer of polyethylene glycol and polypropylene glycol.

29 . The composition of claim 27 wherein said first part comprises 10-65% by weight sodium bicarbonate and 1-10% by weight sodium percarbonate.

30 . The composition of claim 29 wherein said first part contains a partially water soluble calcium salt.

31 . The composition of claim 30 wherein said partially water soluble calcium salt is calcium sulfate.

32 . The composition of claim 17 wherein said first part comprises 0.05-15% by weight each of said at least one calcium salt and phosphate salt.

33 . The composition of claim 32 wherein said phosphate salt is an alkali metal phosphate.

34 . The composition of claim 33 wherein said phosphate salt is dibasic potassium phosphate.

35 . The composition of claim 17 wherein said second part contains a humectant.

36 . The composition of claim 35 wherein said second part contains 25-90% wt. % of said humectant and 3-30 wt. % water.
