Abstract

The hollow particles according to the present invention has a balloon structure which includes a cavity inside a shell, and include convex portions with a size of 3 to 100 nm on the surface. The particles have a true specific gravity of 0.3 to 3.0 g/cm, a specific surface area (m/cm) per unit volume calculated by a BET method of not less than 0.5 and less than 60, and an average particle diameter (d) of 1 to 20 μm. Cosmetics containing such hollow particles have a soft texture property similar to plastic beads.
