A nobiletin composition having high water solubility and a method for easily producing the same are provided. A method for producing a solid dispersion comprising nobiletin, comprising the step of mixing nobiletin or a nobiletin-containing product with a water-soluble hesperidin derivative, and then melting the mixture by heating; and the step of solidifying the melted product by cooling. A nobiletin-containing composition produced by the method.

Method for producing nobiletin-containing solid dispersion

Provided is a method of producing a solid dispersion that can improve solubility of a hardly soluble polyphenol in water. Specifically, provided is a method of producing a solid dispersion containing an amorphous hardly soluble polyphenol, the method including the steps of: mixing (A) a hardly soluble polyphenol, (B) at least one selected from the group consisting of a plant-derived polysaccharide, a seaweed-derived polysaccharide, and a microorganism-derived polysaccharide, a plant-derived polypeptide, and a microorganism-derived polypeptide, and (C) at least one selected from the group consisting of a monosaccharide and a disaccharide, followed by melting of the mixture by heating; and solidifying the molten product by cooling.

Provided are a cosmetic composition which is an O/W/Oemulsion composition and contains, in the oil phases Oand Othereof, fine metal oxide particles having ultraviolet screening ability; and a preparation process of the cosmetic composition.

Cosmetic composition

The present invention relates to a process for producing a decrystallized cellulose having a reduced cellulose I-type crystallinity from a cellulose-containing raw material in an efficient manner with an excellent productivity. In accordance with the present invention, there is provided a process for producing a decrystallized cellulose from a raw material comprising at least 20% by weight, based on the weight of the raw material excluding water contained therein, of a cellulose having a cellulose I-type crystallinity of more than 33% as calculated from the following formula:Cellulose-type Crystallinity (%)=[()/]&#xd7;100wherein Iis a diffraction intensity of a lattice plane (002 plane) as measured at a diffraction angle 2&#x3b8; of 22.6&#xb0; in X-ray diffraction analysis; and Iis a diffraction intensity of an amorphous moiety as measured at a diffraction angle 2&#x3b8; of 18.5&#xb0; in X-ray diffraction analysis, the process including the step of treating the cellulose-containing raw material using a media-type mill to reduce the cellulose I-type crystallinity of the cellulose to 33% or less, wherein the cellulose-containing raw material has a bulk density of from 100 to 500 kg/m.

Process for producing noncrystalline cellulose

Provided is an O/W emulsion cosmetic composition, which contains the following components (A), (B) and (C):

O/W emulsion cosmetic composition

The invention provides a process for producing a granular anionic surfactant, including the steps of carrying out drying and granulation simultaneously while adding an anionic surfactant paste to a powder raw material under reduced pressure in a granulator provided with a stirring blade and a cracking blade to obtain granules.

Process for producing granular anionic surfactant

A process for preparing an aqueous dispersion of pigment-containing polymer particles, comprising the steps of (A) removing an organic solvent from a mixture (I) comprising an organic solvent solution of a polymer, water and optionally a neutralizing agent to give a solvent-removed product; and (B) subjecting the solvent-removed product obtained in step (A) to a dispersion treatment, wherein a pigment is added to the mixture (I) or the solvent-removed product. The aqueous dispersion of pigment-containing polymer particles can be suitably used for a water-based ink for inkjet printing.
