The EU expert panel did not identify an immediate health concern linked to TiO₂ when used as a food additive. However, due mainly to uncertainties concerning the safety of TiO₂ nanoparticles, the panel concluded that TiO₂ as a food additive (E171) could no longer be considered safe.

We've measured many different immunological markers, both in the mucosa of the intestine and the lymphoid organs part of the intestine and we didn't see any inflammation there or changes in white blood cell number, Kaminski said. They also looked at the spleen where titanium dioxide was taken up into the bloodstream. You would expect [titanium dioxide] would be filtered out in the spleen and maybe induce inflammation there, but we did not see that, Kaminski added.

Thanks to its rheological and optical properties, Lithopone offers both technical and economic advantages wherever organic and inorganic binder systems require a relatively high pigmentation for specific applications.

Titanium dioxide particles help light scatter and reflect, Kelly Johnson-Arbor, MD, a medical toxicology physician at the National Capital Poison Center, told Health. Because of that, we often use it as a whitening agent.

All samples (n = 6) were irradiated in a 96 well plate using an LED panel on top for 3 and 6 h before analysis. An identical set of samples were kept in the dark as controls. The temperature was checked and did not go over 37 °C. The intensity of light was also measured and was constant at 19,500.10 lux. (43.33 W in 0.2 m²), about 5 times less than actual solar light intensity on Earth's surface Therefore, these findings are indicative of even greater danger in real life.

According to the feedback of manufacturers, the recent mainstream factory new single price, the market as a whole into the center of gravity. On the demand side, the terminal in August is still the off-season, many downstream still have inventory use, the current batch purchase intention is limited, and the market turnover is low. Some plastics and papermaking related downstream feedback part of the signal price is high. Recent titanium dioxide raw material price shock is strong, titanium dioxide price upward support has been enhanced, comprehensive market factors, the current titanium dioxide market into the stable price state after rising.

As early as sixty years ago, zinc sulphide was first thought of as a pigment for coloring India rubber and a patent for the process of its manufacture was issued in England. But it was not until twenty years later that zinc sulphide and its manufacture was seriously considered as a pigment for paint, and in 1874 a patent was issued for a process of manufacturing a white pigment, composed of zinc sulphide and barium sulphate, known as Charlton white, also as Orr's white enamel. This was followed in 1876 by a patent issued to a manufacturer named Griffith and the product, which was similar in character to Charlton white, was known as Griffith's patent zinc white. In 1879 another patent for a more novel process was obtained by Griffith & Cawley, the product made under this process proving the best of the series placed upon the market up to that date. After that time many new processes were patented, all, however, tending to the same object, that of producing a white pigment, composed of zinc sulphide and barium carbonate, the results, however, in many cases ending with failure.

In summary, the gravimetric determination of titanium dioxide is an invaluable technique in industrial applications. Offering precision and reliability, this method supports various sectors that rely on the quality and consistency of titanium dioxide in their products. By employing effective gravimetric analysis, manufacturers can enhance their operations and maintain competitiveness in a demanding market. As industries continue to evolve, the importance of accurate material analysis remains a cornerstone of successful production practices, ensuring that titanium dioxide remains a key player in future innovations.

Although the evidence for general toxic effects was not conclusive, on the basis of the new data and strengthened methods we could not rule out a concern for genotoxicity and consequently we could not establish a safe level for daily intake of the food additive, commented Matthew Wright, member of the EFSA's Food Additives and Flavourings Panel in a press statement.
