In conclusion, the role of lithopone in the paint industry cannot be overstated. Its unique properties make it a vital component in producing high-quality paints and coatings. As the market continues to evolve with a focus on sustainability and performance, lithopone suppliers are stepping up to meet these challenges through innovative production techniques and a commitment to quality. By partnering with these suppliers, paint manufacturers can ensure they are equipped with the best possible materials to create products that not only meet consumer expectations but also contribute to a more sustainable future.

The toxicity of P25TiO₂NPs was evaluated in both prokaryotic (Fig. 3) and eukaryotic cells (Fig. 4). The XTT assay was chosen to measure the cell viability in bacterial cultures of MSSA, a normal skin microbiota microorganism. The reduction in the viability of samples with bare NPs is notorious, possibly due to the described ROS production from the interaction of P25TiO₂NPs with light [37]. This effect seems to be avoided when they are functionalized with vitamin B2. Also, the most concentrated vitaminB2@P25TiO₂NPs sample (0.2 mg/mL) shows up to 60% more absorbance after 6 h compared to the bare NPs (due to normal cell replication). This may indicate that the antioxidant effect of the vitamin B2 coating is greater than the oxidation damage produced by the NPs. This protective capacity could be attributed to the glutathione redox cycle and the conversion of reduced riboflavin to its oxidized form [38]. Values of cell viability greater than 100% are not rare and could be understood because the XTT assay actually measure metabolic activity when reducing the tetrazole to formazan. It is usually assumed that conversion is dependent on the number of viable cells, but it could also be related to an expected increased enzymatic activity when cells are exposed to small doses of some new substance. Further analysis showed that this effect was not the only one responsible for better cell viability of vitaminB@P25TiO₂NPs treated samples.

What does titanium dioxide do? 

It adds a bright white color to coffee creamers, baked goods, chewing gums, hard-shell candies, puddings, frostings, dressings, and sauces. But the nanoparticles found in “food-grade” titanium dioxide may accumulate in the body and cause DNA damage—which is one way chemicals cause cancer and other health problems. 

The report provides insights into the landscape of the lithopone industry at the global level. The report also provides a segment-wise and region-wise breakup of the global lithopone industry. Additionally, it also provides the price analysis of feedstocks used in the manufacturing of lithopone, along with the industry profit margins.

Particle size: optimum particle size to produce maximum opacity is 200–300 nm.
