The present invention relates to a composite particle comprising: at least one hydrophilic core particle; and a plurality of hydrophobic particles, wherein the surface of the hydrophilic core particle is substantially discontinuously covered by the hydrophobic particles. The novel composite particle according to the present invention can have surface active properties sufficient to prepare stable Pickering emulsions, and can maintain the surface active properties over a long period of time. The present invention also relates to a method for preparing the above composite particle.

Silica-including microcapsule resin particles including an outer shell constituted of a crosslinked polymer and a cavity partitioned with the outer shell, in which the silica-including microcapsule resin particles contain inside the cavity a porous structure in which silica particles are mutually connected, and have a volume average particle diameter of 0.5 to 100 μm.

The disclosure relates to a composition that is designed to be administered to a subject intradermally for treating pigmentless skin or creating a temporary tattoo. The composition comprises particles having a polymeric shell and a core that includes a coloring agent. The particles are in a carrier solution at a concentration that is cosmetically effective to delay the bioabsorbance and/or biodegradation of coloring agent in a subject's skin. Bioabsorbance and/or biodegradation of the particles fades the tattoo until it is no longer visible.

The invention relates to a dispersion of polymer particles stabilized with a stabilizer in a nonaqueous medium containing at least one hydrocarbon-based oil, the polymer of the particles being a C.sub.1-C.sub.4 alkyl (meth)acrylate polymer; the stabilizer being a C.sub.1-C.sub.4 alkyl (meth)acrylate polymer and optionally of a silicone macromonomer (I): the stabilizer being a polymer comprising from 50% to 100% by weight, relative to the total weight of the stabilizer, of C.sub.8-C.sub.22 alkyl acrylate, from 0 to 50% by weight of C.sub.1-C.sub.4 alkyl (meth)acrylate and optionally silicone macromonomer (I). The invention also relates to the composition comprising said dispersion of polymer particles. Cosmetic use for caring for and making up keratin materials.

A method for producing functionalized nanocrystalline cellulose, the method comprising the steps of providing cellulose, mixing said cellulose with a peroxide, thereby producing a reaction mixture, and heating the reaction mixture, and/or exposing the reaction mixture to UV radiation is provided. Functionalized nanocrystalline cellulose produced by this method is also provided.

Anhydrous solid composition comprising an isethionic acid derivative, a glutamic acid derivative, an amphoteric surfactant and fillers The subject of the present invention is a composition, preferably a cosmetic composition, in anhydrous solid form, comprising at least one anionic surfactant chosen from isethionic acid derivatives and salts thereof, at least one anionic surfactant chosen from glutamic acid derivatives and salts thereof, at least one amphoteric surfactant, and at least 20% by weight of fillers, relative to the total weight. The composition in accordance with the invention is advantageously in the form of granules, the particle size of which is homogeneous. It readily disaggregates or disintegrates, it is easy to apply to keratin materials, and it allows rapid foam initiation, when the composition is applied to said keratin materials, and also good foam quality.

The present invention relates a powderous formulation comprising at least one fat-soluble vitamin, which can be produced easily and which can be used in many fields of application.

Silicone particles having excellent dispersibility are provided. A cosmetic material having excellent feeling of use, and a highly functional paint and an electronic material are also provided. The silicone particles include a siloxane as a component. A content of a hydrogen atom bonded to a silicon atom per unit mass is 300 ppm or less. In addition, the silicon atom in the siloxane as a component for the silicone particles is crosslinked with another silicon atom via an alkylene group having a carbon number of 4 to 20.
