SPHERICAL COMPOSITE PARTICLES AND COSMETICS WITH THE PARTICLES BLENDED THEREIN

摘要

PURPOSE: Provided is spherical composite particles adjusted to the desired hardness, softness, and adaptability to be spread smoothly according to a degree of contact feeling required for the cosmetics in which the particles are blended. CONSTITUTION: Spherical composite particles comprise inorganic fine particles and resin fine particles of jointed to each other and the average particle diameter is in the range from 0.5 to 100 nm, in which the average particle diameter of the inorganic fine particles is in the range from 5 to 600 nm and the average particle diameter of the resin fine particles is in the range from 10 to 500 nm. The spherical composite particle comprises an inorganic fine particle and a resin fine particle each having almost same size, jointed to each other, and the hardness, softness, and adaptability to being spread on skin can finely be adjusted to desired ones in a wide range respectively according to the contact feeling required for the cosmetics in which the particles are blended.
