    摘要: The present invention provides a dissolvable strip for whitening teeth. The strip, which is preferably a single layer, has a whitening agent and a water-soluble or water dispersible polymer system. The dissolution of the whitening composition is controlled by interaction of the whitening composition with an oral environment containing saliva. The present invention further provides a process for preparing the whitening strip in the form of a dry film and a method of whitening teeth.

    摘要: A multiple particle (e.g., a spherical particle) comprising an organic solid component (A) containing a plurality of organic solid materials (e.g., polymers) is produced by eluting a water-soluble auxiliary component (B) containing at least an oligosaccharide (B1) from a composition having a disperse system, in which a particulate dispersed phase comprising the organic solid component (A) is dispersed in a matrix comprising the auxiliary component (B). The organic solid materials may be different in affinity relative to the auxiliary component (B) from each other. The particle may have a core-shell structure which comprises a core containing a first organic solid material (e.g., a hydrophobic polymer) and a shell containing a second organic solid material (e.g., a hydrophilic polymer) immiscible with the first organic solid material. The weight ratio of the organic solid component (A) relative to the auxiliary component (B) may be about 55/45 to 1/99. The multiple particle corresponding to the dispersed phase (e.g., a core-shell particle) can be produced by a convenient process independently of affinity between the dispersed phase and the matrix and polymerization manner of the polymer.

    摘要: This invention provides a method for stabilization of a fragrance ingredient in a salt mixture, comprising the steps of encapsulating the fragrance ingredient in a first encapsulating material, which is water soluble and insoluble in a volatile organic solvent, to form a first encapsulated material; encapsulating a salt in a second encapsulating material which is dissolved in a volatile organic solvent to form a second encapsulated material, and then partially drying the second encapsulated material; mixing the first encapsulated material with the second encapsulated material before the volatile, organic solvent completely evaporates from the second encapsulated material; and removing remaining volatile organic solvent to form a free flowing salt and fragrance containing powder.
