Abstract:
Described herein are whitening compositions comprising a substantially anhydrous or non-aqueous oral care composition comprising: a peroxide source comprising hydrogen peroxide bound to cross-linked polyvinylpyrrolidone (cPVP) in the amount effective to provide from 0.01% to 5.5% of hydrogen peroxide, by weight of the composition; a hydrophobic component comprising a silicone polymer; sodium tripolyphosphate; and optionally a dental surface adhesion enhancing agent. Methods of making and using these compositions are also described herein.
Abstract:
The present invention relates to core shell silica particles, wherein each core shell silica particle comprises a silica core, and a surface of the silica core is etched with metal silicate, the core shell silica particles prepared by: i) admixing an amount of silica particles in water with an amount of a base, wherein the base comprises a monovalent metal ion, to produce core shell silica particles, each core shell silica particle comprising a silica core, and a surface of the silica core etched with a silicate of the mono-valent metal ion; and ii) reacting the core shell silica particles formed in step i) with a metal salt comprising a second metal ion, to form core shell silica particles comprising silicate of the second metal ion on the surface of the silica core.
Abstract:
The present invention provides a tooth whitening oral care composition comprising: (i) a dye having a blue to blue-violet color with a hue angle in the CIELAB system ranging from 200 to 320 degrees; (ii) core shell silica particles, wherein each core shell silica particle comprises a silica core, and a surface of the silica core is etched with metal silicate; (iii) an orally acceptable carrier vehicle comprising a non-aqueous solvent; and wherein the composition comprises water in an amount of from 3 weight % to 30 weight %.
Abstract:
Aspects of the invention are directed to oral care compositions having enhanced peroxide stability. In accordance with some aspects, provided is an oral care composition having a polyol; a whitening agent comprising a peroxide; a thickening agent; and an abrasive system comprising insoluble phosphate salts, wherein the oral care composition contains less than about 5 wt. % of water, and all weight percentages are based on the total weight of the oral care composition.
Abstract:
Described herein are oral care compositions comprising: from about 35 wt. % to about 85 wt. % of an anhydrous solvent system (e.g., 35 wt. % to about 75 wt. %); from about 0.02 wt. % to about 30 wt. % of a peroxide solution comprising: from about 0.01 wt. % to about 15 wt. % of hydrogen peroxide, and from about 0.01 wt. % to about 15 wt. % of water; from about 1 wt. % to about 20 wt. % of a thickening system; wherein the oral care composition has a total water content of less than about 30 wt. %; and wherein all weight percentages are based on the total weight of the oral care composition. Methods of making and using these compositions are also described herein.
Abstract:
Described herein are nonaqueous oral care compositions comprising an orally acceptable vehicle, a whitening agent; and one or more gelling agents wherein the one or more gelling agents comprises a salt of a fatty acid; along with methods of making and using same.

Abstract:
An oral treatment device for dispensing an oral treatment composition onto a user's teeth. The oral treatment device may include a storage and delivery component and an applicator component. The storage and delivery component may include a body having a reservoir, a frangible capsule containing the oral treatment composition located in the reservoir, and a delivery member. The applicator component may include a pad portion formed of a liquid absorbing material. The applicator component may be alterable between an attached state whereby the delivery member is fluidly coupled to the pad portion and a detached state whereby the applicator component is detached from the storage and delivery component and can be placed into contact with the user's teeth. The frangible capsule may be in a sealed state until broken by a user at which point the oral treatment composition may flow into the pad portion of the applicator component.
Abstract:
Disclosed herein are oral care compositions comprising an oral care composition comprising a peroxide whitening complex present in an amount to provide from about 3.0% to about 8% of hydrogen peroxide by weight of the composition; a block copolymer of ethylene oxide and propylene oxide in an amount from about 0.01% to about 8% by weight of the composition; a stearate in an amount from about 0.3% to about 5% by weight of the composition; and a humectant in an amount from about 60% to about 90% by weight of the composition. Methods of making and using the oral care compositions are also provided.
Abstract:
An oral care composition and methods for whitening teeth are disclosed herein. The whitening composition may include an orally acceptable vehicle and one or more abrasives. The one or more abrasives may include at least one plant-based abrasive. The method for whitening teeth may include contacting the oral care composition with surfaces of the teeth at least twice a day for at least nine days.
