The Scientific Committee on Consumer Safety issued an opinion of the safety of titanium dioxide in food, stating that it should no longer be considered as safe when used as a food additive.
Molecular Weight: 412.207
The RGB LED panel was built ad hoc for this purpose. Measures: 23.5 × 16.5 cm. Light Intensity: 19,500.10 lux. (43.33 W in 0.2 m2) when set to solar simulation. It does not produce temperature increases in the surroundings.
Still, you may wonder whether it’s safe for consumption.
Inner wall coating factories are continuously working to develop new and improved coatings that meet the growing demand for eco-friendly and sustainable productsInfrared analysis showed that the characteristics bands for the bare nanoparticles are still exhibited in the vitamins@P25TiO2NPs spectra, such as a wide peak in 450–1028 cm−1 related to the stretching vibration of Ti-O-Ti and other peaks in 1630 cm−1 and 3400 cm−1, which represent the surface OH groups stretching. The IR spectrum of vitaminB2@P25TiO2NPs showed signs of binding between compounds. The OH bending peak (1634 cm−1) corresponding to bare nanoparticles disappeared, and the NH2 bending band characteristic of vitamin B2 appeared (1650 cm−1). The IR spectrum of vitaminC@P25TiO2NPs also showed signs of successful functionalization. Bands at 1075 cm−1; 1120 cm−1; 1141 cm−1 were observed, which are originated by CO-C vibrations present in the vitamin C. The intense band at 1672 cm−1 is attributed to the C = O stretching in the lactone ring while the peak at 1026 cm−1 is ascribed to the stretching vibration Ti-O-C. Wide bands at 3880–3600 cm−1 are related to stretching vibration OH groups, but those disappear in the modified nanoparticles spectrum. These observations confirm the interactions between the P25TiO2NPs and the vitamins [35].
Coronavirus-related shutdowns in the first half of the quarter prompted forcible measures at several small-scale ilmenite factories in China and India, subsequently exacerbating the Titanium supply problem. The chemical's tight supply condition was extended until the end of the quarter, as few participants were heard holding cargoes in expectation of an exceptional surge in its seasonal demand.
One of the most common worries about titanium dioxide is that it could be a cancer-causing agent. The link between cancer and titanium dioxide traces back to a 1985 study where rats were exposed to high levels of titanium dioxide for two years, causing lung cancer. However, not all experts are convinced by this study.
Despite its many advantages, TiO2 production is not without its challengesTitanium dioxide comes in the form of a white powder and is sometimes used in cosmetics to adjust a color to a lighter shade. This is also why it can produce a white cast.
Le lithopone est produit par coprécipitation de sulfure de baryum et de sulfate de zinc, le plus souvent en proportions équimolaires, puis grillage de la pulpe résultante4.

In the plastic industry, lithopone is used as a filler and opacifier in plastic formulations. It helps enhance the whiteness and brightness of plastic products, making them more visually appealing
JECFA previously assessed titanium dioxide at its 13th meeting, at which time the expert committee assigned a “not specified” ADI for the additive due to an absence of significant absorption and a lack of toxicological effects in the available experimental animal and human studies. Since its original evaluation by JECFA, titanium dioxide has become a public point of contention, with its ban being introduced (and then subsequently withdrawn) in California legislation in 2023, a legal battle playing out in the EU over the additive’s ban and classification as a carcinogen in 2022, and the European Food Safety Authority (EFSA) calling titanium dioxide unsafe. However, supporters of titanium dioxide say that claims about its dangers are founded in unreliable studies, and some recent research has supported its safety as a food additive.
However, the journey of these suppliers is not without its obstacles. The complexities of global markets, fluctuating raw material costs, and the constant push for environmental sustainability pose significant challenges. Yet, through strategic planning, investment in research and development, and a commitment to excellence, these companies persevere, ensuring that the flow of R960 TIO2 remains uninterrupted. China, as a global manufacturing powerhouse, plays a significant role in the production and supply of various industrial materials, including Lithopone B301. This high-quality pigment is widely used in industries such as coatings, plastics, printing inks, and textiles due to its excellent light stability, heat resistance, and color brightness.Following a request for assessment in 2020 by the EU, the European Food Safety Authority (EFSA) assessed E171, particularly for its genotoxicity. In 2022, the agency deemed the food additive no longer safe for use.
Despite these efforts, challenges remain. As the global demand for TiO2 continues to rise, balancing economic growth with environmental sustainability will be a critical task for China. The country will need to continue innovating and implementing more eco-friendly production methods while ensuring the competitiveness of its TiO2 industry on the global stage. Lithopone, a staple in the paint industry, boasts a unique blend of properties that make it an indispensable component for achieving high-quality finishes. Among its many variants, B301 and B311 stand out as two of the most sought-after types due to their specific characteristics and performance metrics. In this brief exploration, we will delve into the significance of these lithopone grades, discuss factors affecting their price lists, and highlight the role of reputable suppliers in ensuring consistent quality and availability.French researchers studied how and where E171 nanoparticles enter the bloodstream, first studying the route through pigs and then in vitro with human buccal cells, for a 2023 study published in the journal Nanotoxicology. The research showed that the nanoparticles absorbed quickly through the mouth and then into the bloodstream, before damaging DNA and hindering cell regeneration.
