PROBLEM TO BE SOLVED: To provide a spherical powder of biodegradable polymer which has a small environmental load, and has an improved pore shading off effect, feeling like bare skin/translucent skin, touch feeling or sliding property when applying, as well as adherability to the skin, and to provide a cosmetic which is excellent in adherability to the skin by containing this spherical powder of biodegradable polymer.SOLUTION: A spherical powder of biodegradable polymer whose mean particle diameter is 0.5-1.5 μm, and whose particle diameter of particles of 90 volume% or more of the total particles is 3 μm or less is obtained by adding polyglycerol fatty acid ester during manufacturing process. A target cosmetic can be obtained by compounding the obtained spherical powder of biodegradable polymer into a cosmetic.COPYRIGHT: (C)2016,JPO&INPIT【課題】環境への負荷が小さく、毛穴ぼかし効果、素肌感・透明感、塗布時の感触やすべり性に加え、肌への付着性を向上させた球状生分解性ポリマー粉体を提供するとともに、この球状生分解性ポリマー粉体を含有することにより、肌への付着性に優れた化粧料を提供する。【解決手段】製造工程中にポリグリセリン脂肪酸エステルを添加し、平均粒子径が0.5~1.5μmで、全粒子の90体積%以上の粒子の粒子径が3μm以下の球状生分解性ポリマー粉体を得る。得られた球状生分解性ポリマー粉体を化粧料に配合することにより、目的とする化粧料を得ることができる。【選択図】図1
