One of the main uses of TiO2 powder is as a pigment in paints and coatings. It is valued for its excellent opacity, brightness, and UV resistance, making it ideal for use in exterior paints, industrial coatings, and automotive finishes. TiO2 powder suppliers work closely with paint manufacturers to supply them with the right grade and quantity of TiO2 powder to meet their specific requirements.

The safety of the food additive E 171 was re-evaluated by the EFSA ANS Panel in 2016 in the frame of Regulation (EU) No 257/2010, as part of the re-evaluation programme for food additives authorised in the EU before 20 January 2009.  

It's sort of ironic, maybe ironic is the wrong word, that the ingredient in paint that makes your kitchen shiny also makes your Hostess cupcakes shiny, Environmental Working Group's senior vice president of government affairs Scott Faber added.

Developing new Lithopone formulations, one that enhances the properties of the existing Lithopone is anticipated to boost the demand for Lithopone white pigment during the forecast period. Reinforced Lithopone is one such development, wherein a copolymer is added to the polymerization reaction to yield Lithopone with increased weather resistance. Moreover, development of nano-scale Lithopone is anticipated to attract market interest during the forecast period.

In their role as risk managers, the European Commission and Member States will now reflect on EFSA’s scientific advice and decide upon any appropriate regulatory measures or advice for consumers.

Mexican researchers sought to evaluate the effects of E171 across a span of conditions in mice, including its influence on behavior, along with the effects on the colon and liver. The research, published in 2020 in the journal Food and Chemical Toxicology, showed that E171 promoted anxiety and induced adenomas, or noncancerous tumors, in the colon. They also found that E171 heightened goblet cells hypertrophy and hyperplasia, which is typically seen in asthma patients and triggered by smoking or external pollutants and toxins. They also noted mucins overexpression in the mice, which can be linked to cancer cell formation. 

Nano, or ultrafine, TiO₂ comprises primary particles sized less than 100nm. In this grade, titanium dioxide is transparent (colourless) and boasts improved UV scattering and absorbing properties compared with larger particle-size pigmentary TiO₂.

Professor Thomas Faunce spoke out about the rise in auto-immune diseases & childhood autism in relation to the rise of nano-particles in our child food supply. The full article can be found here.

There seems to be a lot of misunderstanding about titanium dioxide, which can be used as a colorant in foods. While headlines may suggest titanium dioxide is a health concern, scientific research has actually shown titanium dioxide to be safe. So what is it used for and why is it used? Read on to learn more!

The pricing of lithopone pigments can fluctuate based on several factors, including raw material costs, production processes, and market demand. Typically, wholesale prices reflect the bulk purchasing power, enabling businesses to acquire these materials at a lower cost per unit. Over the years, the market has seen fluctuations in prices due to changes in the supply chain and global economic conditions. It is crucial for buyers to stay informed about these trends to budget effectively and maintain profitability.

Sulphate process. The ilmenite is reacted with sulphuric acid giving titanium sulphate and ferric oxide. After separation of ferric oxide, addition of alkali allows precipitation of hydrous titanium dioxide. The washed precipitate is calcined in a rotary kiln to render titanium dioxide. The nucleation and calcination conditions determine the crystalline structure of titanium dioxide (e.g. rutile or anatase).

As a widely used substance with multiple applications, research is being carried out to improve the production process to reduce the levels of chemicals used and waste produced, and to recycle any by-products.

The skin of an adult person is, in most places, covered with a relatively thick (∼10 μm) barrier of keratinised dead cells. One of the main questions is still whether TiO₂ NPs are able to penetrate into the deeper layers of the skin. The majority of studies suggest that TiO₂ NPs, neither uncoated nor coated (SiO₂, Al₂O₃ and SiO₂/Al₂O₃) of different crystalline structures, penetrate normal animal or human skin. However, in most of these studies the exposures were short term (up to 48 h); only few long-term or repeated exposure studies have been published. Wu et al.83 have shown that dermal application of nano-TiO₂ of different crystal structures and sizes (4–90 nm) to pig ears for 30 days did not result in penetration of NPs beyond deep epidermis. On the other hand, in the same study the authors reported dermal penetration of TiO₂ NPs with subsequent appearance of lesions in multiple organs in hairless mice, that were dermal exposed to nano-TiO₂ for 60 days. However, the relevance of this study for human exposure is not conclusive because hairless mice skin has abnormal hair follicles, and mice stratum corneum has higher lipid content than human stratum corneum, which may contribute to different penetration. Recently Sadrieh et al. performed a 4 week dermal exposure to three different TiO₂ particles (uncoated submicron-sized, uncoated nano-sized and coated nano-sized) in 5 % sunscreen formulation with minipigs. They found elevated titanium levels in epidermis, dermis and in inguinal lymph nodes, but not in precapsular and submandibular lymph nodes and in liver. With the energy dispersive X-ray spectrometry and transmission electron microscopy (TEM) analysis the authors confirmed presence of few TiO₂ particles in dermis and calculated that uncoated nano-sized TiO₂ particles observed in dermis represented only 0.00008 % of the total applied amount of TiO₂ particles. Based on the same assumptions used by the authors in their calculations it can be calculated that the total number of particles applied was 1.8 × 10¹³ /cm² and of these 1.4 x10⁷/cm² penetrated. The surface area of skin in humans is around 1.8 m²  and for sun protection the cream is applied over whole body, which would mean that 4 week usage of such cream with 5 % TiO₂ would result in penetration of totally 2.6 × 10¹⁰ particles. Although Sadrieh et al.concluded that there was no significant penetration of TiO₂ NPs through intact normal epidermis, the results are not completely confirmative.
