Abstract: A tooth whitening oral care composition is made by combining ingredients comprising flakes of a water soluble whitening film, a dye with a hue angle in the CIELAB system ranging from 200 to 320 degrees, and an orally acceptable carrier vehicle. The flakes of the water soluble whitening film comprise: (a) a film-forming polymer comprising hydroxyalkyl cellulose wherein the hydroxyalkyl cellulose has a viscosity of about 1 to about 1000 millipascal seconds (mPa·s) as determined as a 2% by weight aqueous solution of the film-forming polymer at 20 C using a Ubbelohde tube viscometer; and (b) a pigment with a hue angle in the CIELAB system ranging from 200 to 320 degrees.

Abstract: An oral care implement that dispenses an oral care agent during use and a method of assembling such an oral care implement. The oral care implement may include a body having a head portion. The head portion may have a cavity with an open end. There may be at least one opening extending from the cavity to an outer surface of the head portion. A dissolvable element that includes an oral care agent may be positioned in the cavity. Furthermore, a supporting member may be positioned in the cavity. The supporting member may include a first coupling feature that couples the supporting member to the dissolvable element. Finally, an oral cleaning member may be coupled to the head portion to close the open end of the cavity.

Abstract: An oral care implement that dispenses an oral care agent during use and a method of assembling such an oral care implement. The method may include contacting a suction tool to a supporting member and then contacting the supporting member to a dissolvable element to form a sub-assembly. Next, the sub-assembly may be inserted into a cavity of a head portion of an oral care implement. Then, the suction force applied by the suction tool onto the sub-assembly may be released to leave the sub-assembly in the cavity of the head portion. Finally, an oral cleaning member may be coupled to the head portion of the oral care implement.
