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.

Abstract: Disclosed herein are oral care compositions useful for whitening teeth. The oral care composition may comprise a peroxide source present in an amount to provide from about 0.01 to about 1 wt.% peroxide; a base in an amount up to about 5 wt.%; benzyl alcohol present in an amount from about 0.2 to about 1 wt.%, wherein the oral care composition has a pH of about 8 to about 12 and all weight percentages are based on the total weight of the oral care composition. Methods of making and using the oral care compositions are also provided.

Abstract: The application is directed to efficient and economical processes as described in more detail below for the preparation of the beta 3 agonists of the formula of I-7 and intermediate compounds that can be used for making these agonists. The present disclosure relates to a process for making beta-3 agonists and intermediates using ketoreductase (KRED) biocatalyst enzymes and methods of using the biocatalysts.

Abstract: A tooth whitening kit and method of whitening teeth using the same. The method may include applying a tooth whitening composition directly to surfaces of a user's teeth, exposing the surfaces of the user's teeth to ambient air for a first period of time to form a film of the tooth whitening composition on the surfaces of the user's teeth, applying light to the surfaces of the user's teeth for a second period of time while the film of the tooth whitening composition remains on the surfaces of the user's teeth, ceasing application of the light to the surfaces of the user's teeth and leaving the film of the tooth whitening composition on the surfaces of the user's teeth for a third period of time, and removing the film of the tooth whitening composition from the surfaces of the user's teeth.

Abstract: Described herein is an oral care implement comprising: a handle; and a head coupled to the handle, the head comprising a main body and a release component coupled to the main body, the release component comprising: a water-dissolvable matrix comprising a first polymer having a processing temperature greater than or equal to 130° C.; and a release agent comprising at least one of zinc oxide, potassium nitrate, and tetrapotassium pyrophosphate; wherein the release agent is dispersed throughout the water-dissolvable matrix.

Abstract: A method of whitening teeth that decreases the amount of time that the whitening composition is in contact with the teeth. Specifically, by pretreating the whitening composition with light before contacting the teeth with the whitening composition, the amount of time that the whitening composition needs to be in contact with the teeth can be reduced. In one aspect, the method may include dispensing a tooth whitening composition from a reservoir device into a channel of a mouth tray; activating an electromagnetic radiation source to emit light onto the tooth whitening composition in the channel of the mouth tray for a first period of time to pretreat the tooth whitening composition; and inserting the mouth tray into the oral cavity of the user so that the user's teeth are in contact with the tooth whitening composition in the channel for a second period of time to whiten the teeth.

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 %.
