Titanium dioxide can boost and brighten colors because of how well it absorbs and also scatters light. In food and drugs, this additive is known as E171 and helps define colors clearly and can prevent degradation (cracking and breakdown of materials) from exposure to sunlight.
- Both 28B301 and 30B311 are white pigments with high brightness and excellent covering power. They are commonly used in coatings, plastics, rubber, and paper industries. The main difference between these two grades lies in their particle size distribution. 28B301 has a smaller particle size, resulting in higher opacity and better dispersion. On the other hand, 30B311 has a larger particle size, which makes it more suitable for applications that require good rheological properties.

- The global market for precipitated titanium dioxide is competitive, with suppliers operating on both regional and international scales. Some prominent players include Evonik Industries, Cristal Global, Tronox, and Venator Materials. These companies not only focus on production but also invest heavily in research and development to innovate and improve their products continually.
- In conclusion, anatase titanium dioxide nanoparticles are emerging as factories for advanced applications due to their unique properties and vast potential. As research continues to advance, we can expect to see even more innovative uses for these fascinating nanoparticles in the future.

The compound in the Asia Pacific market experienced a mixed trends throughout the fourth quarter of 2021. These market attitudes were mostly related to lower operational loads at Chinese domestic manufacturing plants.
- One such manufacturer that specializes in the production of titanium dioxide is ABC Company. ABC Company has been in the business of manufacturing titanium dioxide for over 20 years and has established a strong reputation for delivering high-quality products to its customers. The company prides itself on its state-of-the-art manufacturing facilities and its commitment to innovation and sustainability.

Lithopone factory: Natrosol has some characteristics
- In addition to price, it is also important to consider the quality of the superfine calcium carbonate. High-quality calcium carbonate will have a consistent particle size, high brightness, and low impurities. This can have a significant impact on the performance of the product, as well as the overall quality of the end product.

A great number of other brands with fancy names have gone out of the German market, because of some defects in the processes of manufacture. The English exporters, as a rule, offer three or four grades of lithopone, the lowest priced consisting of about 12 per cent zinc sulphide, the best varying between 30 and 32 per cent zinc sulphide. A white pigment of this composition containing more than 32 per cent zinc sulphide does not work well in oil as a paint, although in the oilcloth and shade cloth industries an article containing as high as 45 per cent zinc sulphide has been used apparently with success. Carefully prepared lithopone, containing 30 to 32 per cent sulphide of zinc with not over 1.5 per cent zinc oxide, the balance being barium sulphate, is a white powder almost equal to the best grades of French process zinc oxide in whiteness and holds a medium position in specific gravity between white lead and zinc oxide. Its oil absorption is also fairly well in the middle between the two white pigments mentioned, lead carbonate requiring 9 per cent of oil, zinc oxide on an average 17 per cent and lithopone 13 per cent to form a stiff paste. There is one advantage in the manipulation of lithopone in oil over both white lead and zinc oxide, it is more readily mis-cible than either of these, for some purposes requiring no mill grinding at all, simply thorough mixing with the oil. However, when lithopone has not been furnaced up to the required time, it will require a much greater percentage of oil for grinding and more thinners for spreading than the normal pigment. Pigment of that character is not well adapted for use in the manufacture of paints, as it lacks in body and color resisting properties and does not work well under the brush. In those industries, where the paint can be applied with machinery, as in shade cloth making, etc., it appears to be preferred, because of these very defects. As this sort of lithopone, ground in linseed oil in paste form, is thinned for application to the cloth with benzine only, and on account of its greater tendency to thicken, requires more of this comparatively cheap thinning medium, it is preferred by most of the manufacturers of machine painted shade cloth. Another point considered by them is that it does not require as much coloring matter to tint the white paste to the required standard depth as would be the case if the lithopone were of the standard required for the making of paint or enamels. On the other hand, the lithopone preferred by the shade cloth trade would prove a failure in the manufacture of oil paints and much more so, when used as a pigment in the so-called enamel or varnish paints. Every paint manufacturer knows, or should know, that a pigment containing hygroscopic moisture does not work well with oil and driers in a paint and that with varnish especially it is very susceptible to livering on standing and to becoming puffed to such an extent as to make it unworkable under the brush. While the process of making lithopone is not very difficult or complicated, the success of obtaining a first class product depends to a great extent on the purity of the material used. Foreign substances in these are readily eliminated by careful manipulation, which, however, requires thorough knowledge and great care, as otherwise the result will be a failure, rendering a product of bad color and lack of covering power.
This precipitate is not suitable for a pigment until it is filtered, dried, crushed, heated to a high temperature and quenched in cold water. The second heating in a muffle furnace at 725 °C produces crystals of the right optical size.
Titanium dioxide is one of the many oxides formed naturally in our environment. Manufacturers source this mined mineral from rutile, brookite, and anatase. It is then processed and refined to meet stringent safety guidelines based on the end-use for the mineral.
Prof. Matthew Wright, chair of EFSA’s working group on E171, noted: “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.”

Research has shown that, when ingested as a food additive, titanium dioxide and its nanoparticles can impact, alter, and/or damage important protective bacteria in the gut, along with the metabolic pathways of gut bacteria.

In its statement to USA TODAY, the FDA maintained that, in all post-approvals for food additives, our scientists continue to review relevant new information to determine whether there are safety questions and whether the use of such substance is no longer safe under the Federal Food, Drug, and Cosmetic Act.
