Abstract: The present invention provides resin beads that can provide various types of products, such as a cosmetic having excellent tactile impression, spreadability on the skin, and transparency, that can be substituted for resin particles composed of a synthetic material derived from petroleum, and that have favorable biodegradability, and the present invention also provides various types of products, such as a cosmetic using the resin beads. The resin beads are formed with a resin containing cellulose as a main component. The resin beads have a cumulative 50% particle size on a volume basis of 50 μm or smaller, a degree of sphericity of 0.7 to 1.0, a degree of surface smoothness of 70 to 100%, a degree of solidity of 50 to 100%, and a biodegradation rate for 5 days, as measured in accordance with JIS K6950:2000 (ISO 14851:1999), of 20% or more, and the content of the cellulose in the resin is 90 to 100% by mass. In addition, the present invention provides a product of any one of a cosmetic, a dermatological preparation, a paint, a shaped article, a film, a coating agent, and a resin composition which contain the resin beads.

Abstract: A method of simultaneously modifying degradation rates of at least two compounds including a first compound having a first unmodified degradation rate constant k1 and a second compound having a second unmodified degradation rate k2 is provided. The method includes combining a first composition including the first compound with a second composition including the second compound, degrading the first compound and forming a first degradation product; and degrading the second compound and forming a second degradation product. The second degradation product modifies the first unmodified degradation rate constant k1 of the first compound to a first modified degradation rate k1′ and the first degradation product modifies the second unmodified degradation rate k2 of the second compound to a second modified degradation rate k2′. Compositions resulting from the method are also provided.

Abstract: The present invention relates to a biodegradable polyester resin, in which the first repeat unit comprising a first diol residue and an aromatic dicarboxylic acid residue and the second repeat unit comprising a second diol residue and an aliphatic dicarboxylic acid residue satisfy a ratio of the number of repeat units in a specific range, and the softness index of the resin satisfies a specific range, and to a process for preparing the same. Since the biodegradable polyester resin can provide a biodegradable polyester sheet or film that can be simultaneously enhanced in productivity, processability, and moldability and is excellent in tensile strength, tear strength, and friction coefficient and excellent in biodegradability and water degradability, it can be utilized in more diverse fields.

Abstract: Provided is a method that can produce a resin porous material from a water-insoluble polymer in a small number of steps while suppressing the formation of skin layers. The production method of a resin porous material disclosed herein includes preparing a solution of a water-insoluble polymer in a mixed solvent including a good solvent of the water-insoluble polymer and a poor solvent of the water-insoluble polymer, and drying the solution to remove the mixed solvent. The poor solvent has a higher boiling point than the good solvent. The drying the solution is performed using superheated water vapor.
