When used in an ultrafine-grade formulation, titanium dioxide becomes transparent to light, effectively making it an absorber of UV light. And because its particles are so small in this form, titanium dioxide creates a transparent barrier that absorbs UV light.
CAS NO. :
With its storied history and distinct properties, lithopone remains a subject of historical significance and contemporary relevance. While its applications and popularity have evolved, its role in the annals of pigment history is indisputable.
lithopone supplier 30% has a lower coverage power than titanium dioxide. For this reason, lithopone supplier 30% can only partially substitute titanium dioxide, between 5 and 40%.
EFSA Scientific Conclusion on E171

Titanium dioxide has also been classified as a possible human carcinogen by the International Agency for Research on Cancer, which has caused concern about its use in food products. This classification, however, is currently based on limited evidence from animal studies that involved the inhalation of titanium dioxide particles that increased the risk of lung cancer.
Natural barite and anthracite containing more than 95% barium sulfate are mixed and fed at a ratio of 3:1 (mass). After being crushed to a diameter of less than 2cm, it enters the reduction furnace. The furnace temperature is controlled to be 1000-1200°C in the front section and 500-500 in the back section. 600°C, the reduction furnace rotates at a speed of 80 seconds per revolution, and the reaction conversion rate is 80% to 90%.
Pigmentary TiO2 particles are approximately 200-350nm in dimension and this form accounts for 98 percent of total production. It is used mainly for light scattering and surface opacity applications. It is used as a base for various colour paints or as a standalone ‘brilliant’ white.
