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.

Manufacturers specializing in dissolvable titanium dioxide have adopted a unique approach that combines science, innovation, and environmental consciousness. The first step in this process is the extraction of titanium from naturally occurring minerals like rutile and ilmenite. This is done through either the sulfate or chloride process, both of which involve extensive chemical reactions to extract pure titanium dioxide. The global demand for lithopone has been steadily increasing in recent years, driven by the growth of the construction, automotive, and electronics industriesThe integrity of surface skin cells was evaluated with and without solar simulated irradiation. The integrity of the stratum corneum was significantly lower in individuals treated with P25TiO2NPs under the light in comparison to the ones that received the functionalized nanoparticles. Cell membrane suffering is evident (Fig. 9), and it is in accordance with the ROS levels and macromolecule oxidation found in vitro for the irradiated P25TiO2NPs. Disruption of the superficial skin layer was observed in all animals treated with no functionalized nanoparticles, under irradiation. This data expands the findings by the group of Professors Fubini and Fenoglio, who showed that P25TiO2NPs could impact the lipid structure at the top few microns of the stratum corneum [55]. Control skin under irradiation and without any topic formulation did not show changes in cell structure.
Over the last several years, nanoparticles have come under scrutiny for adverse health effects. Nanoparticles are ultrafine particles between 1 to 100 nanometers in diameter. (To put this in perspective, the average human hair is around 80,000 nanometers thick.) Because of their size, which can be engineered and manipulated at the atomic or molecular level, nanoparticles exhibit unique physical, chemical, and biological properties. Titanium dioxide is one of the most commonly produced nanoparticles in the world.
Packaging containing this additive has been shown to decrease ethylene production in fruit, thus delaying the ripening process and prolonging shelf life (4Trusted Source).
As a food additive, titanium dioxide and its nanoparticles in particular have been associated with DNA damage and cell mutations, which in turn, have potential to cause cancer. When used as a food coloring, it is known as E171.
The factories where lithopone is produced adhere to strict quality control measures to ensure that the pigment meets the required specifications for different applications2. Relative density: 4.136 to 4.39 g/mL.
Beyond its technical attributes, Lomon's commitment to sustainability is embedded in the production of R-996. The company adheres to strict environmental norms, ensuring minimal ecological impact during the manufacturing process. This eco-friendly approach aligns with the growing global demand for responsibly sourced and produced materials. Geopolitical events also have the potential to create volatility in the titanium dioxide market. For example, political unrest in titanium-rich regions can disrupt mining operations and limit the global supply of the material, leading to price spikes. Trade policies and international tariffs can similarly influence cross-border transactions and affect overall costs.Freshwater algae show low-to-moderate susceptibility to TiO2 exposure, with more pronounced toxic effects in the presence of UV irradiation. It has also been shown that nano-sized TiO2 is significantly more toxic to algae Pseudokirchneriella sub-capitata than submicron-sized TiO2. Hund-Rinke and Simon reported that UV irradiated 25 nm TiO2 NPs are more toxic to green freshwater algae Desmodesmus subspicatus than UV irradiated 50 nm particles, which is in agreement with Hartmann et al. UV irradiated TiO2 NPs also inactivated other algae species such as Anabaena, Microcystis, Melsoira and Chroococcus. It was demonstrated that smaller particles have a greater potential to penetrate the cell interior than submicron-sized particles and larger aggregates. Studies have shown that the amount of TiO2 adsorbed on algal cells can be up to 2.3 times their own weight.
This route affords a product that is 29.4 wt % ZnS and 70.6 wt % BaSO4. Variations exist, for example, more ZnS-rich materials are produced when zinc chloride is added to the mixture of zinc sulfate and barium sulfide.[1]
In conclusion, titanium dioxide stands as a testament to the marvels of chemistry and engineering. As we continue to explore its potential, it remains an essential part of the wholesale pigment industry, contributing to products that touch every aspect of our lives. From enhancing the vibrancy of colors to combating pollution and advancing renewable energy technologies, titanium dioxide is indeed a remarkable substance with an ever-expanding palette of applications.In a 2019 study published in the journal Nanotoxicology, researchers recreated the first phase of digestion in mice and fed them titanium dioxide, then examined whether accumulation occurred in the organs. Researchers wrote: “Significant accumulation of titanium was observed in the liver and intestine of E171-fed mice; in the latter a threefold increase in the number of TiO2 particles was also measured. Titanium accumulation in the liver was associated with necroinflammatory foci containing tissue monocytes/macrophages. Three days after the last dose, increased superoxide production and inflammation were observed in the stomach and intestine. Overall, [this] indicates that the risk for human health associated with dietary exposure to E171 needs to be carefully considered.”
When sourcing lithopone, businesses typically consult with manufacturers who provide detailed price lists. These lists outline the costs associated with different types of lithopone, such as those tailored for specific solvent resistance or heat stability requirements. Prospective buyers should expect to find a range of options, from economy grades suitable for general-purpose uses to more sophisticated varieties intended for exacting industrial applications.Furthermore, titanium dioxide is finding increasing use in the cosmetics industry. It is commonly added to sunscreens for its ability to block both UVA and UVB radiation, offering broad-spectrum protection against harmful sunlight. Its antimicrobial properties are also advantageous in personal care products like deodorants and makeup, where it helps to extend shelf life and maintain product safety.
Titanium dioxide is produced at pigment grade or nano grade.
One of the key factors contributing to the popularity of R996 TiO2 among paint factories is its environmental sustainability In the wholesale market, titanium dioxide is available in various forms, including anatase, rutile, and brookite. Each form offers distinct advantages depending on the specific application requirements. For instance, anatase titanium dioxide is known for its high photocatalytic activity, making it an ideal choice for environmental applications such as air purification and water treatment. Rutile, on the other hand, is characterized by its high refractive index and excellent weathering resistance, making it a preferred choice for automotive coatings and plastic additives.
