Abstract:
A barium sulfate-based powder is produced by bringing barium ions (A) into contact with sulfate ions (B) in the presence of one or more metallic ion species (C) selected from the group consisting of lithium ions, sodium ions, potassium ions, magnesium ions, calcium ions, zinc ions, and aluminum ions. Thus, barium sulfate-based powders having various characteristics and thus satisfying functional requirements for cosmetics can be obtained.
