2. Material Quality Not all fiber tanks are created equal. The type of fiber used, the thickness of the material, and the overall design can impact the durability and, consequently, the price. High-quality tanks may come with a higher initial investment but can save money in the long term due to their longevity.

- Overall, titanium dioxide plays a critical role in the paper industry by improving the quality, performance, and appearance of a wide range of paper products. Its unique optical properties make it a valuable additive for enhancing the whiteness, brightness, and opacity of paper, while also providing important functional benefits such as print quality, show-through prevention, and light stability.
- The production process of titanium dioxide involves several stages, starting with the extraction of raw materials from mineral ores such as ilmenite, rutile, and anatase. These ores are then processed through various methods, including the sulfate and chloride processes, to produce high-purity titanium dioxide powder. The sulfate process involves treating the ore with sulfuric acid to extract titanium dioxide, while the chloride process uses chlorine gas to produce a purer form of the pigment.
- 2. Particle Size and Shape The particle size and shape of ZnS can significantly impact its performance in various applications. Therefore, it is essential to choose suppliers who can offer a range of particle sizes and shapes to suit different requirements.

On the other hand, the U.S. Food and Drug Administration (FDA) in their Final Administrative Order on Sunscreen Drug Products posted in September 2021 still accepts titanium dioxide up to 25% in the list of Generally Recognized As Safe and Effective (GRASE) in the main document, without further clarification on what kind or size of particles [9]. However, on page 24 (Sunscreen containing nanomaterials) FDA clearly “distinguish nanomaterials from other forms of these ingredients'' (zinc oxide and titanium dioxide) and ask for comments on “any particular nanomaterials that you believe should not be permitted for use in OTC sunscreen products”. To the best of our knowledge, this Agency did not ban the use of nanoparticulate titanium dioxide in any form, even though it is mentioned on page 34 that the anatase form is the more photoactive one, due to the lack of evidence with real sunscreens OTC (over the counter) in vivo. Moreover, other regulations in Latin America (MERCOSUR agreement, 2006) do not state clearly their position on the use of nanoparticulate TiO2NPs [10].
The leading Chinese TiO2 exporter in value and quantity has been Sichuan Lomon, followed by Henan Billions and Gansu CNNC Huayuan. However, Sichuan Lomon exported a value of titanium dioxide by USD100,000,000 more than the second rank Henan Billions. Henan Billions, on the other hand, exported over USD70,000,000 more TiO2 than Gansu CNNC Huayuan. This demonstrates the huge monopole-like position of the newly merged company Henan Lomon, which can determine the market development for TiO2 in China nearly all alone.
Titanium dioxide (E 171) is authorised as a food additive in the EU according to Annex II of Regulation (EC) No 1333/2008.
However, most dermatologists will warn their patients not to rely on mineral makeup alone in order to be protected by the sun’s rays. This is because there can be quite a bit of variation with mineral foundation – not only with how much we apply but how much titanium dioxide the foundation contains.

The price of Titanium Dioxide in Taiwan rose considerably throughout December 2018, reaching 3,750 USD per metric ton. The price in Taiwan is 10% higher than the average price in the previous month and 1% higher than the average price one year before. In contrast, Titanium Dioxide prices in India were flat during December 2018, and were decline when compared to the average price in the preceding yeara decline of 3% from the previous year’s price.
Studies have been carried out with both emulsion paints and powder paints, both with clear results on how the use of Lithopone 30% reduces the appearance of algae in the paint once it has been applied (see photos).
Though the Food and Drug Administration (FDA) categorizes titanium dioxide as Generally Recognized as Safe (8), other organizations have issued warnings.

Permanence and Stability
Recently, Yanagisawa et al. reported that the transdermal exposure (mimicking skin-barrier dysfunction or defect) of NC/Nga mice to TiO2 NPs (15, 50, or 100 nm), in combination with allergen, aggravated atopic dermatitis-like lesions through a T-helper type 2 (Th2) dominant immune response. The study also indicated that TiO2 NPs can play a role in the initiation and/or progression of skin diseases, since histamine was released, even in the absence of allergen.
Gravimetric Determination of Titanium Dioxide in Industrial Applications
Furthermore, the use of titanium dioxide in rubber helps to reduce the environmental impact of rubber manufacturing processes. As a non-toxic and environmentally friendly material, titanium dioxide is safe for use in rubber products that come into contact with food, water, or other sensitive materials. This makes it an attractive choice for manufacturers looking to produce eco-friendly and sustainable rubber goods.

Titanium dioxide is added to some food packaging to preserve the shelf life of a product.
In some studies, E171 was given to animals in drinking water without the stabilizers that keep E171 suspended in the liquid. Without stabilizers, E171 can settle and prevent the ingredient from combining with surrounding ingredients.
