Barium Sulfate

What is Barium Sulfate?

Barium sulfate, chemically BaSO4, is an inorganic, insoluble white powder derived synthetically from barium chloride and sodium sulfate for purity in cosmetics. Naturally occurring as the mineral barite, its cosmetic-grade form ensures fine particle size and stability. Primarily featured in makeup like foundations, concealers, and face powders, it functions as an opacifying agent by scattering light to reduce transparency, yielding a creamy, even appearance that conceals particles or imperfections. As a colorant, it delivers a bright white pigment, aiding shade consistency across products. Its water-insolubility prevents skin penetration, making it suitable for surface-level aesthetic enhancement in various formulations including some sunscreens. Approved by regulators for cosmetic use, it prioritizes visual appeal without biological reactivity.
