For research published in Archives of Toxicology in 2020, scientists fed one group of mice a solution containing titanium dioxide for one month, and compared it to those that did not receive the additive. They found “the richness and evenness of gut microbiota were remarkably decreased and the gut microbial community compositions were significantly changed” in the titanium dioxide group when compared with the control group. The tests also revealed that the titanium dioxide exposure could cause locomotor dysfunction, or mobility issues “by elevating the excitement of enteric neurons, which might spread to the brain via gut-brain communication by vagal pathway.” The researchers concluded: “These findings provide valuable insights into the novel mechanism of TiO2NP-induced neurotoxicity. Understanding the microbiota-gut-brain axis will provide the foundation for potential therapeutic or prevention approaches against TiO2NP-induced gut and brain-related disorders.”
While the conclusions of the EU expert panel were considered in this report, Health Canada's Food Directorate conducted its own comprehensive review of the available science. This included evaluating new scientific data that addressed some of the uncertainties identified by the EU expert panel and were not available at the time of their review.


Titanium dioxide (TiO2) is by far the most suited white pigment to obtain whiteness and hiding power in coatings, inks and plastics. This is because it has an extremely high refractive index and it does not absorb visible light. TiO2 is also readily available as particles with the right size (d ≈ 280 nm) and the right shape (more or less spherical) as well as with a variety of post-treatments.
However, the pigment is expensive, especially when the volume prices of systems are used. And, there always remains a need to develop a full-proof strategy to obtain the best results in terms of cost/performance ratio, scattering efficiency, dispersion… while using it in coating formulations. Are you searching for the same?
Explore the detailed knowledge of TiO2 pigment, its scattering efficiency, optimization, selection, etc. to achieve the best possible white color strength and hiding power in your formulations.
Additionally, the growing emphasis on sustainability within the automotive industry influences the demand for environmentally friendly tire production methods. TiO2, being a non-toxic and eco-friendly compound, aligns with these sustainability goals, making it an attractive option for manufacturers looking to reduce their environmental footprint.

The most common foods containing titanium dioxide are chewing gum, candies, pastries, chocolates, coffee creamers, and cake decorations (1Trusted Source, 3Trusted Source).


Currently, titanium dioxide as a food additive is classified as GRAS, or “generally recognized as safe.”
The precipitation of titanium dioxide involves the reaction of titanium sulfate with an alkaline solution to form titanium hydroxide, which is then calcined to produce titanium dioxide. The precipitation process is crucial for achieving the desired particle size distribution, crystallinity, and purity of the final product.
Application:
1. Due to its rheological and optical properties, Lithopone offers technical and economic advantages wherever organic and inorganic resin systems need to be relatively highly pigmented for specific applications. Lithopone has therefore traditionally been used in putties, mastics, jointing and sealing compounds, primers, undercoats and marking paints. In powder coatings it is possible to replace TiO2 partially, very economically.
2. The low Mohs' hardness of Lithopone leads to low abrasiveness in comparison with TiO2.
3. Lithopone 30 % (= 30% zinc sulfide share) is proven to be of particular use as a TiO2 Substitute in thermoplastic masterbatches. Even at very high pigment loadings it disperses easily. A masterbatch containing 50 % TiO2 and 25 % Lithopone 30 % DS has the same hiding power as one containing 60 %TiO2. Cost savings are strongly related to the price ratio of Lithopone and TiO2 and the price of for example polyethylene or polypropylene.
4. The Lithopone batch has a much higher extrusion rate too. Furthermore the impact strength of many thermoplastics such as PP and ABS can be noticeably improved by using Lithopone as a TiO2 substitute. Generally spoken, Lithopone can be used at loadings up to 80 % by weight without causing polymer breakdown
