The principal natural source of titanium dioxide is mined ilmenite ore, which contains 45-60 percent TiO₂. From this, or an enriched derivative (known as titanium slag), pure TiO₂ can be produced using the sulphate or chloride process.

The lack of clear regulations and controls explains that P25TiO₂NPs are still found in many of the commercialized sunscreens in the market. Some of them are coated to reduce the photoactivity of the anatase form, which is known to be responsible for tissue damage, but not enough studies were made on these coated forms. The anatase photoactivity could trigger the production of reactive oxygen species (ROS) generation, as it was stated before. The ROS are chemically reactive species containing oxygen, such as peroxides, superoxide, hydroxyl radical, and singlet oxygen. They are regularly produced in the biological milieu and counterbalanced by physiological antioxidant defense mechanisms. However, an abrupt increase of ROS may result in non-reversible damage to the skin cells. The effects of coated and uncoated P25TiO₂NPs need therefore to be studied, and articles on this topic present different conclusions. [11], [12], [13] Recent literature on this topic found that TiO₂NPs inhalation provokes serious genotoxicity and DNA damage [14], [15], [16], [17]. On the other hand, some studies in rats have reported no significant harm to genetic material [18], [19], [20], [21], [22].

Demand in the European region has been significantly boosted by higher offtakes in the furniture, building, and industrial sectors compared to Q2, after a boost in containment measures. DIY activities increased significantly as people engaged in more home renovation and building tasks during the extended period of lockdown. With the restart of Chinese shipments in the latter half of Q2 2020, supply has also remained plentiful.

In the application of lithopone in ink industry, lithopone has fine particles, loose structure, good fineness and good paint adhesion, so it can be well combined with other colors in the composition of ink.

Titanium dioxide is a mineral that’s used as a white coloring in a variety of products, including sunscreens, cosmetics, paints, and plastics. The pigment grade is also known as titanium white, pigment white 6, or CI 77891; it's the whitest and brightest of all known pigments.

In addition to its physical properties, titanium dioxide also has environmental benefits. As a non-toxic compound, it is safe to use in homes, offices and public places. Coatings formulated with titanium dioxide contain virtually no volatile organic compounds (VOCs), ensuring minimal impact on indoor air quality and human health. Additionally, due to their long-lasting nature, titanium dioxide-infused paints can help create a more sustainable environment by reducing waste and the need for frequent repainting.

Here's what you need to know about titanium dioxide:

Permanence and Stability

But before titanium dioxide is made into sunscreens, it is first micronized. This is a process that takes ingredients that are normally quite heavy (like titanium dioxide) and makes them both stabler and easier to spread. And when micronized, titanium dioxide doesn’t penetrate the skin. That means that you’re getting all the sun protection benefits without the risk of harming yourself.
