Technical data sheet
HK-400 Food-Contact Anatase TiO₂
HK-400 is a food-contact anatase titanium dioxide for food and pharmaceutical applications: high whiteness and hiding power, excellent dispersibility and chemical inertness, and low heavy-metal content.
Food & Pharma Grade
≥ 99 %TiO₂ Content
≤ 3 ppmArsenic (As)
≤ 10 ppmLead (Pb)
Key benefits
- High whiteness and hiding power with excellent dispersibility and chemical inertness
- Low heavy-metal content: arsenic (As) ≤ 3 ppm, lead (Pb) ≤ 10 ppm
- TiO₂ content ≥ 99 %, with low acid-soluble and water-soluble matter
- For food (confectionery, bakery, dairy, beverages) and pharmaceuticals (tablet coating, capsule shells)
- Standard 25 kg bags
