  • Publication number: 20240261207
    Abstract: Composite particles include particles of a cellulose derivative and a film covering a surface of the particles of the cellulose derivative. The film is formed of a surface treatment compound that dissolves in water and/or an organic solvent. A cosmetic composition contains the composite particles. A method for producing the composite particles includes mixing particles of a cellulose derivative and a surface treatment compound, wherein the particles of the cellulose derivative and the surface treatment compound are stirred and mixed in a solvent that dissolves the surface treatment compound; and drying a solid content containing the particles of the cellulose derivative, wherein the solid content is washed and dried. A preferable solvent is water or an alcohol.

  • Publication number: 20240228741
    Abstract: Provided is a cellulose acylate composition containing cellulose acylate particles and metal compound-containing particles. The total degree of substitution of the cellulose acylate is from 0.7 to 2.9. The metal compound is one or more types of compounds selected from an alkali metal compound and an alkaline earth metal compound. The composition is produced by adding one or more types of metal compounds selected from an alkali metal compound and an alkaline earth metal compound during and/or after removing a water-soluble polymer from a dispersion containing, as a dispersoid, cellulose acylate impregnated with a plasticizer to form cellulose acylate particles.
