About

Insoluble barium sulfate — an inert white mineral used as a pigment and opacifier. Highly safe on skin; the toxic barium salts are the soluble ones, not this insoluble form.

Skin benefits

  • Inert white pigment and opacifier
  • Improves coverage in makeup
  • Used in pharma and food-contact
  • Stable and unreactive

Known concerns

  • Inhalation of fine dust should be avoided
  • Soluble barium salts (not this one) are toxic
