Abstract
Biodegradable resin particles including a polyhydroxy alkanoate. In the biodegradable resin particles, an amount of a Ca component present in the particles is 10 to 10,000 ppm, the biodegradable resin particles have a volume average particle diameter of 2 to 50 μm, the biodegradable resin particles have a BET specific surface area of 0.8 to 10 m/g, and the biodegradable resin particles have a linseed oil absorption of 50 to 300 ml/100 g. The resin particles of the present invention can be suitably used by being included in an external preparation, such as a cosmetic or a quasi-drug.
