Titanium Dioxide Powder
Introduction
Titanium Dioxide (TiO2) remains the gold standard in industrial opacification due to its exceptionally high refractive index, which effectively scatters light to produce brilliant whiteness and unmatched covering power. In commercial scale-up, the primary bottleneck with raw mineral powders is particle agglomeration, which leads to chalky textures, uneven film coatings, and blocked nozzles in spray applications. Shaanxi Runke addresses this by employing advanced micron-level milling and surface-treatment protocols, ensuring absolute particle uniformity. Whether you require anatase or rutile crystalline structures for specific UV-scattering profiles in cosmetics, or high-purity FCC grades for compliant confectionery coatings in North America, our TiO2 guarantees seamless dispersion across aqueous, lipid, and dry-powder matrices without structural degradation.

Benefits
Superior light-scattering capabilities mean formulators can achieve brilliant white hues or create opaque backgrounds for other pigments using minimal dosing.
Chemically and biologically inert. It will not react with other active ingredients, degrade under UV light, or shift in color under extreme pH or thermal stress.
Milled to an exact micron profile to ensure seamless integration into lipid phases without grittiness.
Applications
A foundational physical UV filter in sunscreens and a premium opacifying agent in foundations, creams, and soaps.
The industry standard for film coatings on tablets and capsules, protecting light-sensitive APIs from degradation.
Utilized in regions where permitted (e.g., US FDA) for whitening candy coatings and dairy alternatives.
