Composite spherical polymer particles and their production process, and cosmetics using the same |
摘要 |
Composite spherical polymer particles contain a nanoparticulate pigment having an average primary particle size of from 0.1 to 0.005 μm, a high molecular dispersant having adsorptive property to the nanoparticulate pigment, and a (meth)acrylic resin. The nanoparticulate pigment is enclosed in a dispersed state in the high molecular dispersant and (meth)acrylic resin. The content of the nanoparticulate pigment ranges from 5 to 70 wt % based on the composite spherical polymer particles. The composite spherical polymer particles have an average particle size of from 1 to 20 μm. A production process of the composite spherical polymer particles and cosmetics containing the composite spherical polymer particles are also disclosed.
