A dental bleaching device may include a flexible backing material, and a dental composition in contact with the flexible backing material. The dental composition may include a thickening agent and a peroxide bleaching agent. The dental composition may be a gelatinous compound having physical deformation properties that allow the dental composition to bend and conform to a shape of a container into which the dental composition is placed, but the dental composition will not merge into a second piece of the dental composition when placed in contact with the second piece. The dental composition will not crack or break when the dental bleaching device is flexed.

The present invention relates to a cosmetic composition, preferably for keratin fibers such as compositions for coloring hair, comprising at least these components: a. tris(hydroxymethyl)aminomethane; b. at least one amino acid; c. at least one organic phosphate ester compound selected from: c1. monoester of phosphates of alkoxylated fatty alcohols, wherein the alkoxylated fatty alcohols are composed of C12-C22 fatty alcohols alkoxylated with from 1 to 50 moles of an alkylene oxide, wherein the number of moles of alkylene oxide is with respect to the moles of fatty alcohol; c2. diester of phosphates of non-alkoxylated fatty alcohols, wherein the non-alkoxylated fatty alcohols are composed of C12-C22 fatty alcohols; and c3. mixtures of c1 and c2; d. water; the present invention further refers to a process of manufacturing a dispersion comprising the aforementioned cosmetic composition; a kit of two or more components for coloring keratin fibers; a ready-to-use composition obtainable by mixing the kit components; and a process for coloring keratin fibers comprising said ready-to-use composition.
