Titanium Dioxide FAQ
1. What is the difference between rutile and anatase Titanium Dioxide?
Rutile Titanium Dioxide has higher refractive index (2.7) and better weather resistance compared to anatase (2.55). Rutile is preferred for outdoor applications, while anatase is used where high whiteness and blue undertone are required.
2. Is Titanium Dioxide safe for food applications?
Food-grade Titanium Dioxide (E171) is approved by regulatory agencies when used within specified limits. However, some countries have restrictions, so always check local regulations before use in food products.
3. How does particle size affect Titanium Dioxide performance?
Smaller particles (0.2μm) provide better scattering of visible light (opacity), while larger particles (0.3μm) are more effective at scattering UV light. Optimal particle size depends on the specific application requirements.
Quality Assurance
Our Titanium Dioxide undergoes rigorous quality control:
- Batch-to-batch consistency

4. What is the shelf life of Titanium Dioxide?
Properly stored Titanium Dioxide has an indefinite shelf life. However, we recommend using within 24 months for optimal performance, especially for critical applications like cosmetics.
5. Can Titanium Dioxide be used in water-based systems?
Yes, our specially treated grades disperse easily in water-based systems. For best results, use recommended dispersing agents and follow proper dispersion protocols.
6. How does Titanium Dioxide compare to alternative white pigments?
Titanium Dioxide offers superior opacity, brightness, and UV resistance compared to alternatives like zinc oxide or calcium carbonate. It has the highest refractive index of all white pigments (2.7 for rutile).
