FAQ Section
1. What makes Titanium Dioxide different from other white pigments?
Titanium Dioxide offers superior opacity and brightness compared to alternatives like zinc oxide or calcium carbonate. Its high refractive index (2.76) provides excellent light-scattering properties, resulting in more efficient coverage and whiteness. Additionally, TiO2 demonstrates better chemical stability and resistance to UV degradation.
2. Is Titanium Dioxide safe for use in food and cosmetics?
Food-grade Titanium Dioxide (E171) has been approved as a food additive in many countries, though regulations vary by region. In cosmetics, TiO2 is commonly used in sunscreens for its UV-blocking properties. Always verify the specific regulatory status in your target market and ensure you're using the appropriate grade for your application.
3. What's the difference between rutile and anatase Titanium Dioxide?
The two crystalline forms differ in several aspects:
- Rutile: Higher refractive index (2.76), better durability, more weather-resistant, slightly yellowish undertone
- Anatase: Higher photocatalytic activity, brighter blue-white tone, less stable in outdoor applications
