Described herein are oral care compositions comprising a crosslinked polyvinylpyrrolidone complexed with hydrogen peroxide, together with particular co-polymers as additional excipients; including some embodiments which further comprise a calcium abrasive.

Oral care compositions

Oral care compositions comprising: In one embodiment, the carrier comprises a film forming material. Methods are also provided for making an oral care composition comprising:

Oral care composition with cross-linked polymer peroxide

Anhydrous oral care compositions and methods for preventing phase separation in the anhydrous oral care composition are disclosed. The oral care composition may include an orally acceptable vehicle, a thickening system, and a whitening agent. The orally acceptable vehicle may include propylene glycol, and the thickening system may include a polymeric thickener. The polymeric thickener may be or include a copolymer of 2-acrylamidomethylpropanesulphonic acid or a salt thereof.

Oral care compositions and methods for increasing stability of the same

Oral care compositions and methods for whitening and preventing stains on teeth are provided. The oral care composition may include an orally acceptable vehicle, a peroxide whitening agent, and an abrasive system. The orally acceptable vehicle may include a block copolymer of ethylene oxide and propylene oxide, and the abrasive system may include at least one insoluble phosphate salt.

Whitening compositions and methods for increasing stability of the same

Described herein are oral care compositions comprising (i) a peroxide whitening agent comprising a whitening complex of crosslinked polyvinylpyrrolidone complexed with hydrogen peroxide, (ii) sodium acid pyrophosphate (NaHPO) in an amount of from 0.05 wt % to 5 wt % based on the weight of the composition, and (iii) less than 3 wt % water based on the weight of the composition.

Peroxide-stable oral care compositions

Provided is a single phase oral care composition having a whitening agent; a first abrasive selected from calcium pyrophosphate, calcium carbonate, and dicalcium phosphate; a second abrasive that may include sodium metaphosphate; an anticalculus agent; and a substantially anhydrous carrier that may include an ethylene oxide/propylene oxide copolymer. In the composition, a wt % of the second abrasive is equal to or greater than a wt % of the first abrasive.

Single phase whitening dentifrice with high purity metaphosphate abrasive

Described herein are oral care compositions comprising a thickening system comprising a first thickening agent and a second thickening agent, wherein the first thickening agent comprises greater than 15 wt % of the mixture of the first and second thickening agents in the thickening system.

Oral care compositions for tooth whitening

Described herein are oral care compositions comprising (i) a peroxide whitening agent comprising a whitening complex of crosslinked polyvinylpyrrolidone complexed with hydrogen peroxide, (ii) sodium acid pyrophosphate (NaHP2O) in an amount of from 0.05 wt % to 5 wt % based on the weight of the composition, and (iii) less than 3 wt % water based on the weight of the composition.

Described herein are oral care compositions comprising (i) a whitening complex comprising crosslinked polyvinylpyrrolidone complexed with hydrogen peroxide, and (ii) a hydrogen peroxide stabilizing agent comprising a clay comprising a lithium magnesium silicate or a sodium magnesium silicate, or a combination thereof.

Described herein are whitening compositions comprised of a peroxide component, and an adhesion system, which effectively provide whitening using a remarkably low level of peroxide. Methods of making and using these compositions are also described herein.
