Patent No.: US7862801B2  Issued: 04/Jan/2011

Title: Adhesive dental bleaching compositions comprising polyvinylpyrrolidone

Applicant/Assignee: ULTRADENT PRODUCTS, INC

Application No.: 10/870293   Filing Date: 17/Jun/2004

Abstract:

A dental bleaching composition comprises a dental bleaching agent and a polyvinylpyrrolidone thickening agent. The bleaching composition may include water, flavoring agents, a basic substance and desensitizing agents, as desired. Polyvinylpyrrolidone avoids acid etching and chelation of teeth that were problematic in bleaches using carbomer as a thickener. A delivery system for delivering the bleaching composition comprises the aforementioned dental bleaching composition in combination with a moisture-resistant barrier layer such as a dental tray or a flexible strip of material.

Title: Patches for teeth whitening

Applicant/Assignee: LG HOUSEHOLD & HEALTH CARE LTD

Application No.: 10/915283   Filing Date: 10/Aug/2004

Abstract:

The present invention relates to a dry type tooth whitening patch comprising peroxide as a tooth whitening agent. In particular, disclosed is a dry type tooth whitening patch in which a peroxide is contained, as a teeth whitening agent, in a matrix type adhesive layer. The adhesive layer includes, as a base polymer thereof, a hydrophilic glass polymer which provides a strong adhesion to teeth while releasing the tooth whitening agent when hydrated on the enamel layers of teeth in the moist oral cavity. The dry type patch according to the present invention is convenient in use, as compared to wet type patches. Further, it exhibits a superior adhesion while being maintained in a state attached to the teeth for a lengthened period of time so as to assure an enough contact time between the whitening agent in the patch and stains on the teeth, thereby giving a sufficient whitening effect.

Title: Particulate Flavoring Composition

Applicant/Assignee: QUEST INTERNATIONAL B.V

Application No.: 10/591570   Filing Date: 04/Mar/2005

Abstract:

The present invention relates to particulate compositions comprising controlled release particles wherein discrete elements of flavouring-containing fat are dispersed in a gelatine matrix, the particles containing

0.1-40 wt %, preferably 5-30 wt % of flavouring

10-70 wt %, preferably 20-50 wt % of gelatine

and 0.1-75 wt %, preferably 5 -0 wt % of fat, the fat having a melting point of at least 35 DEG C.

the particles having a volume weighted average diameter of 50-1500 [mu]m. The particulate composition according to the present invention will release the flavouring comprised therein under specific conditions e.g. under the influence of shear forces, heat and/or moisture. The release rate upon consumption can be affected by varying the relative amounts of gelatine and fat and the gelling strength of the gelatine.

These compositions are therefore particularly suitable for imparting longer lasting taste sensation to confectionaries, in particular chewing gum, and to toothpaste.
