The porous-cellulose particles according to the present invention are constituted by gathered crystalline celluloses having a type I crystal form including a glucose molecule as a constitutional unit. That is, porous-cellulose particles having high sphericity have been achieved from a natural raw material. The porous-cellulose particles have an average particle diameter of 0.5 to less than 50 μm, a specific surface area of 50 to 1000 m.sup.2/g, and a sphericity of 0.85 or more. Cosmetic products containing such porous-cellulose particles have excellent texture properties.

The purpose of the present invention is to provide a powder composition that can be used for cosmetics or skin topical agents and that replaces plastic powder bodies such as a nylon powder body, an acrylic powder body, and a urethane powder body. Provided is a composition which is a powder composition containing (a) acyllysine and (b) cellulose and/or starch, and which has a median diameter of the volume-based distribution of (A) acyllysine of 9 μm or less. The contained amount of (A) is 2-40 mass %, and the contained amount of (B) is 3-95 mass %, with respect to 100 mass % of the total of the powder composition. The total amount of (A) and (B) is 10 mass % or more.

The pigment is composed of particles having a lattice constant a of 5.4700-5.5100 Å and containing a calcium-titanium composite oxide as a main component. The pigment selectively transmit light in a warm-color range, and can be used as an alternative material for titanium oxide. This pigment can be used for a cosmetic, for example.

The present invention provides a modified formula to make a hydrophilic foam. In some embodiments this modified formula adds a filler which causes the foam to become less absorptive, which has the benefit of making available to the skin more makeup or other products, while also providing a superior esthetic application of makeup on the skin. In other embodiments the modified formula makes the hydrophilic foam easier to clean and reduces the staining propensity of the foam. In other embodiments the modified formula uses an additive to the properties or usability of the foam in some way. Providing the filler and additive can be done in combination or separately depending on the desired benefits or properties of the foam. In some embodiments the foam is fashioned into a shape suitable for makeup application.

Disclosed are a cosmetic composition having increased skin contact and makeup persistence and a method of manufacturing the same. The method includes: forming a powder continuous phase by rapidly mixing a powder and a film-forming agent; and obtaining a cosmetic composition in which a surface of the powder is compounded with the film-forming agent by heating the powder continuous phase for a predetermined time. In an embodiment, the cosmetic composition is manufactured by the method. In an embodiment, the cosmetic composition includes 5 wt % to 30 wt % of a powder, 0.1 wt % to 10 wt % of a film-forming agent, 10 wt % to 30 wt % of a silicone oil, and 0.1 wt % to 10 wt % of a spherical powder.

The present invention concerns a sphere, characterized in that it comprises at least one polymer of hyaluronate and glucomannan. It also concerns a polymer of hyaluronate and glucomannan characterized in that each bond between a hyaluronate group and a glucomannan group is an ester bond. In addition, it concerns their production process and their use, in particular as a filling or hydration agent.

The present invention relates to a composition, especially a cosmetic composition, particularly a photoprotective composition, comprising at least: —photonic particles having an average size comprised from 0.5 μm to 100 μm and each including an arrangement that diffracts monodisperse nanoparticles or voids, the diffraction spectrum of this arrangement including a reflection peak of the first order in the range of wavelengths ranging from 250 nm to 1800 nm, preferably from 250 nm to 400 nm, —at least one absorber, said absorber being a molecule having an absorption spectrum in the UV-near IR domain (100 nm-3000 nm) whose mass extinction coefficient ε1% is greater than or equal to 160 g.sup.−1.Math.100 mL.Math.cm.sup.−1, and —at least one surfactant.

The present invention relates to a particle composition comprising XRD amorphous calcium magnesium phosphate particles and a method for manufacturing such a composition. The XRD amorphous calcium magnesium phosphate particles are spherical particles with a hollow core. The particle-containing paste may be used in dental products such as toothpaste to treat dentin hypersensitivity by mineralizing and occluding exposed dentin tubules.

The present invention relates to a microparticle-structured thickener having improved sensation of use. Even when swelling in an aqueous phase, the thickener according to the present invention shows the advantage of retaining the form of particles as well as appearing transparent and being high in stability because the particles disperse homogeneously.

This invention relates to the use of microgranules comprising destructurized starch in a complexed form as abrasive and/or structuring agents in cosmetic, dermatological, detergent and cleansing formulations.
