The present disclosure concerns a cosmetic product for modifying the natural color of keratinous fibers, in particular human hair, comprising at least one packaging (VP) and a cosmetic composition (KM) contained in this packaging (VP). The packaging is made of a multi-layer film (F) comprising at least two polymer layers (P1) and (P2) and at least one barrier layer (BS). The cosmetic composition comprises at least one oxidizing agent and at least one thickening agent from the xanthane group. The use of the packaging (VP) in combination with the cosmetic composition (KM) does surprisingly not lead to an inflation of the packaging or an excessive water loss of the agent (KM) during storage.

According to the present invention, provided is a core-shell structured chromic microcapsule having a size of 50-1,500 m, comprising: a core comprising a colorant core (A) and an optional inner color layer (B); and a shell comprising a pressure sensitive destructible wall layer (C) encompassing the core, an optional outer color layer (D) and an optional outermost protective layer (E), wherein the colorant core allows a high content of a colorant to be contained, and the pressure sensitive destructible wall layer comprises carbon dioxide particles and a binder comprising one or more wall-forming materials and one or more lipid-base materials. The chromic microcapsule according to the present invention has high colorant content, has excellent storage durability, maintenance durability and color-hiding property of the inner color layers, is easily destroyed by pushing, rubbing, polishing or scrubbing with the hands or a tool (cotton fabric, sponge or paper) so as to express the color of the inner color layers, and can maintain stability for a long time even if being added into a carrier.

This invention provides a multilayer dissolvable solid article, which comprises two or more flexible, dissolvable, porous sheets. Each of such two or more sheets is characterized by a Percent Open Cell Content of from about 80% to 100% and an Overall Average Pore Size of from about 100 m to about 2000 m and comprises a water-soluble polymer. At least two adjacent sheets in such dissolvable solid article are characterized by an Adhesion Score (AdS) of no less than 1, while the contacting surfaces of said at least two adjacent sheets are essentially free of adhesives. Preferably, the multilayer dissolvable solid article is essentially free of adhesives.

In a tooth whitening method, a whitening composition is applied to at least one tooth. The whitening composition is maintained on the at least one tooth for a first time period. After the first time period, a light radiation is directed toward the at least one tooth for a second time period. The first time period has a duration greater than 50% of a total duration of the first and second time periods.

The described invention relates, in part, to a water-free, toothbrush-free oral composition in the form of a tablet, comprising neem, xylitol, one or more polymers, optionally magnolia bark extract, and a coating, wherein the tablet is activated in situ by a chewing action and/or by contacting saliva, and methods of use.

A permeable layer associated relative to a phase change material associated relative to a securing fabric layer. The permeable layer retains a therapeutic or cosmetic agent to be transferred, in whole or in part, to the user's skin. The phase change material may be dissolved within a thermoplastic matrix or situated within a suitable container. This invention provides the novelty of a phase change material, coupled with a permeable layer and a fabric layer, which work in conjunction with a therapeutic or cosmetic agent.

The present application provides an oral care composition comprising: a) one or more omega fatty acids; and one or more of the following: b) one or more emulsifying agents; c) one or more protease enzymes; d) one or more soluble calcium phosphate remineralizing agents; e) one or more amino acids.

A solid cosmetic product includes: (i) a first effervescent material, and (ii) a second effervescent material. The second effervescent material contains a salt of alginic acid. Each effervescent material is capable of effervescence on contact with water, with the rate of effervescence of the first effervescent material being greater than the rate of effervescence of the second effervescent material. The first and second effervescent materials are distinct from each other and the second effervescent material envelops the first effervescent material. The solid cosmetic product includes (a) a salt of carbonic acid; (b) an organic acidifying agent; (c) a salt of alginic acid; and (d) a calcium salt.

There are provided a cosmetic sheet that obscures a discolored portion of the skin and a method for producing the cosmetic sheet. There are also provided an image-processing apparatus and an image-processing method for producing the sheet. The cosmetic sheet is put on a discolored portion of the skin. The cosmetic sheet includes a thin film, one surface of which is to be put on the skin, a complementary color layer placed on the other surface of the thin film and having a color tone complementary to the color of the discolored portion, a light scattering layer placed on the complementary color layer and containing a reflective material, and a coloring layer placed on the light scattering layer and containing a coloring material.

The present application provides an oral care composition comprising: a) one or more omega fatty acids; and one or more of the following: b) one or more emulsifying agents; c) one or more protease enzymes; d) one or more soluble calcium phosphate remineralizing agents; e) one or more amino acids.
