  • Titanium dioxide anatase is a crystalline form of titanium dioxide, widely used in various industries due to its unique properties. As a supplier of titanium dioxide anatase, we understand the importance of providing high-quality products to meet the diverse needs of our customers.
  • In recent years, the demand for titanium dioxide has been on the rise due to its increasing use in the construction and automotive sectors. As a result, the expansion of TiO2 factories is a strategic move for many companies, reflecting the sector's robust growth prospects.
  • 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].

  • In 2022, a year after the EFSA recommended against the use of E171, the Food Standards Australia New Zealand (FSANZ) conducted its own reassessment of titanium dioxide as a food additive. The agency concluded that titanium dioxide was indeed safe to use as a food additive. The United Kingdom and Canada came to similar conclusions.

  • On the other hand, Lithopone B301 is a lower-grade pigment with a lower zinc sulfide content compared to B311. While B301 may not offer the same level of performance as B311, it is still a cost-effective option for applications where high opacity is not a priority

  • lithopone supplier 30% applied in masterbatch has maximum purity, good opacity and reasonable light fastness.  

  • In recent years, there has been a growing demand for lithopone in the global market, driven by the increasing use of the pigment in various industries, such as construction, automotive, and packaging. This has led to a rise in the number of factories producing lithopone, particularly in China, where the majority of the pigment is manufactured.
  • One of the primary reasons for the popularity of titanium dioxide is its excellent whiteness and opacity. It has a high refractive index, which means it can scatter light very effectively, making it an ideal choice for creating bright, vibrant colors. In addition, titanium dioxide is highly resistant to weathering and fading, making it a durable pigment that can withstand extreme conditions.

  • In the meantime, the chemical factories of Continental Europe, principally in Germany, Austria and Belgium, had taken hold of the novelty and under the collective name of lithopone or lithophone, by numerous processes, produced various grades of the pigment, branding the respective qualities as red seal, green seal, yellow seal, blue seal, etc., or selling them under some fancy name. Of this we shall speak later on. The crusade against the use of white lead in the various countries of Continental Europe, assisted the manufacturers, to a very great extent, in marketing their products, not only to industrial concerns, as has been the case in this country, until recently, but to the general painting trade. Up to 1889 the imports into this country were comparatively small. At that time one of the largest concerns manufacturing oilcloth and linoleum in the State of New Jersey began to import and use Charlton white. Shortly after that other oilcloth manufacturers followed suit, replacing zinc white with lithopone in the making of white tablecloth, etc., and later on abandoning the use of white lead in floor cloth and linoleum. This gave an impetus to several chemical concerns, that erected plants and began to manufacture the pigment. Competition among the manufacturers and the activity of the importers induced other industries to experiment with lithopone, and the shade cloth makers, who formerly used white lead chiefly, are now among the largest consumers. Makers of India rubber goods, implement makers and paint manufacturers are also consumers of great quantities, and the demand is very much on the increase, as the nature of the pigment is becoming better understood and its defects brought under control. Large quantities find their way into floor paints, machinery paints, implement paints and enamel paints, while the flat wall paints that have of late come into such extensive use owe their existence to the use of lithopone in their makeup.

  • For a review published in 2023 in the journal Environmental Pollution, researchers examined E171 as a possible factor promoting obesity-related metabolic disorders. Because gut microbiota play an important role in immune function maintenance and development, and because titanium dioxide as a food additive has been shown to alter gut microbiota, researchers wanted to review “the dysregulations along the gut microbiota-immune system axis after oral TiO2 exposure compared to those reported in obese or diabetic patients, and to highlight potential mechanisms by which foodborne TiO2 nanoparticles may increase the susceptibility to develop obesity-related metabolic disorders.” The study authors discovered recurrent changes in the gut microbiota composition when exposed to titanium dioxide nanoparticles, with an imbalance of intestinal symbiotic microbiota. These changes and imbalances were also reported and played a role in the development of obesity, the authors wrote. This highlights “foodborne TiO2 nanoparticles as an endocrine disruptor-like chemical promoting obesity-related disorders,” the authors concluded.

  • The wholesale titanium dioxide (TiO2) market is a key sector in the global chemical industry, with a wide range of applications in various end-use industries such as paints and coatings, plastics, paper, and textiles. Titanium dioxide is a white pigment that is used to impart opacity, brightness, and durability to products.
  • 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.

  • A 2022 review on past studies of titanium dioxide and rat lung cancer, for instance, said the original study was under extreme conditions and its effects were not replicated in other animal species. Additionally, the review concluded that the few studies which did directly focus on titanium dioxide's impact on humans did not end up showing any increased cancer risk.

  • In 2019, EFSA published a statement on the review of the risk related to the exposure to food additive titanium dioxide (E171) performed by the French Agency for Food, Environment and Occupational Health Safety (ANSES). In its statement, EFSA highlighted that the ANSES opinion reiterated the uncertainties and data gaps previously identified by EFSA and did not present findings that invalidated the Authority’s previous conclusions on the safety of titanium dioxide.

  • However, China's Tio2 pigment industry is not without challenges
  • According to a recent report by ResearchAndMarkets.com, the global titanium dioxide market was valued at USD 18.9 billion in 2020 and is expected to grow at a compound annual growth rate (CAGR) of 5.3% from 2021 to 2027. The Chinese market accounts for a significant portion of this growth, with domestic production and consumption of titanium dioxide expected to increase at a faster pace than the global average.
  • The trend in the production of NPs is likely to lead to increasing amounts of nano-powders in the air, water and soil, which will consequently affect living organisms. Labielle et al. demonstrated that 25 % of Al(OH)3-coated TiO2 particles from sunscreens are dispersed as a stable colloid and become available to microorganisms and filter-feeders, while the remaining 75 % are probably incorporated into geogenic sediments, where they could become available to benthic fauna. Solar UV iradiation may penetrate as far as 20 m in the water column  and therefore photo-activate the dispersed particles, which may have an adverse effect on various aquatic organisms.

  • First, the ammonia leaching method is used as a technical means for the effective treatment of acid leaching slag, and the nano nitrite powder is prepared under a weak alkaline ( Ή 8 8.5 to 10) ammonia environment. In an alkaline environment, some metal impurities such as The solubility of Ca, Mg, Fe and Al hydroxides is low, and the impurities entering the final immersion liquid in the selective leaching of ammonia-ammonium sulfate are reduced, thereby ensuring the quality of the product; the traditional acid method for preparing lithopone is because of the zinc calcination. In the roasting and reduction process of the alkalized alkali, the elemental sulfur and sulfite are more or less produced, and the prepared white powder has a yellowish color, and the metathesis reaction of the patent is carried out in an ammonia solution (alkaline). The final product obtained is sulfate, which is quickly and thoroughly added by desulfurization through 3⁄40 2 , and the whiteness of the product can be ensured without high temperature calcination; the equipment requirement is lower than that of sulfuric acid leaching, and the ordinary steel leaching tank can complete the leaching; The environmental pollution problem of acid leaching residue, especially effectively solves the environmental pollution of heavy metals such as zinc, copper, lead, cadmium and arsenic in acid leaching residue and the influence of acid ions on the storage environment. Realize the recycling of high-value metal zinc in acid leaching slag, realize the acidity improvement of soil and have the comprehensive advantages of low cost, energy saving and environmental protection.
  • Safety Concerns and Regulations
  • Anatase titanium dioxide is widely used in the coatings industry, thanks to its excellent properties and versatile applications. Coatings manufacturers appreciate the unique characteristics of anatase titanium dioxide that make it a preferred choice for a variety of coating products.
  • The FDA has issued guidance clarifying the safe use of titanium dioxide pigment as a food colorant and has stated that titanium dioxide may be safely used in cosmetics, including those intended for use around the eye. FDA also regulates the safety and effectiveness of sunscreen active ingredients, including nanoscale titanium dioxide.
