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

An oral care composition, including a catalyzing enzyme and an anhydrous matrix configured to at least partially stabilize the catalyzing enzyme, wherein the anhydrous matrix includes a source of hydrogen peroxide, an acyl donor, a non-aqueous anhydrous liquid, and a surfactant mixture including sodium lauryl sulfate (SLS), Betaine, and a poloxamer.

Compounds and methods for preparing and using the compounds are disclosed herein. The method for preparing the compounds may include contacting a metal ion or salt thereof with an alkali metal polyphosphate salt in an aqueous medium. The method may also include adding a base to increase a pH of the aqueous medium.

Described herein are regimens for whitening the teeth, comprising administering to the teeth an effective amount of a first oral care composition comprising a bleaching agent and allowing the first oral care composition to remain on the teeth for at least 30 seconds, and brushing the teeth with a second oral care composition. Kits comprising a first oral care composition comprising a bleaching agent, wherein said first oral care composition is adapted to remain on the teeth for at least 30 seconds; a second oral care composition; and instructions for use, are also provided.

Methods for whitening teeth

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.

Oral care whitening compositions

Described herein are oral care compositions comprising a crosslinked polyvinylpyrrolidone complexed with hydrogen peroxide, together with a blue to violet-blue pigment; including some embodiments which further comprise an ethylene oxide, propylene oxide block co-polymer.

Whitening oral care compositions

Described herein are oral care compositions comprising a silsesquioxane silicone resin and a solvent; and methods of making and using the same.

An encapsulated oral care composition includes: (a) a gelatin capsule; and (b) a oral care composition contained within the capsule, and including: (i) a hydrophilic active; (ii) a hydrophobic structuring agent; and (iii) an oil carrier. The hydrophilic active is preferably cetylpyridinium chloride. The hydrophobic structuring agent is preferably a gelled mineral oil. The oil carrier is preferably a vegetable oil. A method of cleaning teeth includes applying to the teeth the encapsulated oral care composition such that the capsule releases the oral care composition to clean the teeth. A oral care implement includes: a handle; a head mounted to the handle, the head having an outer surface and a plurality of tooth cleaning elements extending outwardly from the outer surface; and the encapsulated oral care composition positioned on the head.

Gelatin encapsulated oral care composition containing hydrophilic active, hydrophobic structuring agent and oil carrier

A oral care composition includes: (a) a hydrophilic film-forming polymer; and (b) a hydrophobic carrier, wherein the hydrophilic film-forming polymer is a film-forming polymer effective to occlude dentinal tubules and the oral care composition contains 0-10 wt. % water. The hydrophilic film-forming polymer is preferably GANTREZ S. The hydrophobic carrier is preferably a vegetable oil. A method of cleaning teeth includes applying to the teeth the oral care composition such that the hydrophilic film-forming polymer occludes dentinal tubules. A toothbrush includes: a handle; a head mounted to the handle, the head comprising an outer surface and a plurality of tooth cleaning elements extending outwardly from the outer surface; and a gelatin capsule containing the oral care composition positioned on the head.

Non-aqueous oral care composition containing dental occlusion actives

Oral care compositions comprising a crosslinked polyvinylpyrrolidone complexed with hydrogen peroxide, together with an ethylene oxide-propylene oxide block copolymer. Some embodiments further comprise a calcium abrasive, e.g. calcium pyrophosphate or calcium carbonate, and some may have less than 3% water.
