Zirconium Dioxide
What is Zirconium Dioxide?
Zirconium dioxide, chemically ZrO₂ and known as zirconia, is an inorganic ceramic material obtained by processing zircon mineral at high temperatures. It forms a dense, white crystalline powder valued in the cosmetics sector, especially color cosmetics including foundations, powders, and concealers, but also in select skincare items. As an opacifying agent, it works by diffusely reflecting and scattering visible light across its high refractive index surface, thereby decreasing product translucency to deliver a consistent, creamy, and visually uniform texture. This light interaction masks undissolved particles and enhances overall formula aesthetics without altering color significantly. Its exceptional chemical stability and insolubility ensure durability during production and application, positioning it as a reliable inert additive in opaque emulsions and suspensions.
