Titanium Dioxide (Rutile Type, Food Grade) CAS#13463-67-7
Outstanding Whitening Performance: Rutile titanium dioxide offers superior whiteness, brightness, and exceptional hiding power, efficiently masking base colors and providing an opaque, clean white finish in food applications.
Excellent Chemical Stability: Chemically inert, insoluble in water, acids, and organic solvents. Resists heat, UV light, and oxidation, ensuring stable color and no fading during processing and storage.High Safety & Purity: Food-grade standard with TiO₂ purity ≥99.0%, strict limits on heavy metals (As, Pb, Cd, Hg), complying with FAO/WHO and FCC food safety standards.Easy Dispersion: White crystalline powder, fine particle size (200–300 nm), good dispersibility in aqueous and oily food systems, uniform distribution without agglomeration.
Product Details
With molecular formula TiO₂, rutile-type food-grade titanium dioxide is a safe, high-purity white colorant, widely used in food, pharmaceuticals, and cosmetics for its stable properties and reliable performance.
