1. An oral care composition for whitening teeth comprising:
- a peroxyacetic acid generating mixture including a source of peroxide and source of labile acyl groups, wherein the source of labile acyl groups is a C1-C5 molecule having between 1 to 5 labile C1-C5 acyl containing groups dispersed within an anhydrous carrier.

Abstract
Novel compositions and methods are disclosed for cosmetically treating teeth in a manner to increase brightness or shade of the teeth. The compositions include a low molecular weight compound having a high acetyl group functionality useful in the production of a peroxy acid which then acts as a whitening agent.

18. A composition for producing peroxyacetic acid for use in whitening teeth, the composition comprising a two component system including:
-
a first component including a hydrogen peroxide releasing compound and a second component including glyceryl triacetate.
-
-
19. A method for whitening teeth comprising:
-
forming a composition by combining a hydrogen peroxide precursor, glyceryl triacetate, and water so as to generate peroxyacetic acid; and
applying the composition to a tooth surface.
-
-
20. A method for whitening teeth comprising:
-
applying one of either a glyceryl triacetate or a hydrogen peroxide releasing compound onto a tooth surface; and
applying the other of the remaining glyceryl triacetate or hydrogen peroxide releasing compound onto the same tooth surface, so as to generate peroxyacetic acid upon contact with an aqueous solution on the surface of the tooth.

-
21. A method for whitening teeth comprising:
-
providing separately glyceryl triacetate and a hydrogen peroxide releasing compound, both in an orally safe and sufficient amount for whitening teeth;
forming a mixture between the glyceryl triacetate and the hydrogen peroxide releasing compound; and
applying the mixture onto a tooth surface.
-
-
22. A method for cosmetically treating teeth comprising the steps of:
-
applying a source of labile acetyl groups onto the surface of a tooth;
allowing the source of labile acetyl groups to penetrate into the tooth;
applying a source of peroxide onto the surface of the tooth;
allowing the source of labile acetyl groups to react with the source of peroxide anion to generate a peroxyacid within the tooth; and
allowing the peroxyacid to effect whitening of the tooth. - View Dependent Claims (23, 24, 25, 26, 27)
