Most notably, a European Food Safety Authority safety assessment published in May 2021 pointed to genotoxicity concerns, as suggested by previous research. Genotoxicity is the ability of chemicals to damage genetic information such as DNA, which may lead to cancer.

The robustness of calcium compounds is not only limited to their diverse applications but also reflects in their stability during storage and transportation. This durability makes them an ideal product for wholesale manufacturers who often deal with long supply chains and need products that can maintain quality throughout the distribution process.

Other techniques that manufacturers may consider include spectrophotometry, which measures the absorbance of light by a sample at specific wavelengths, and atomic absorption spectroscopy (AAS), which uses a flame to atomize sample compounds and measure the absorption of light by the resulting atoms.

There are several factors to consider when evaluating an anatase titanium dioxide pigment supplier. Firstly, it is important to assess the quality of the pigment being offered. Look for a supplier that provides high-quality pigment that meets industry standards and specifications. This ensures that you are getting a product that will perform well in your applications and deliver the desired results.

Australia and New Zealand review of TiO2

Despite these advancements, the pigment lithopone industry faced competition from alternative pigments like titanium dioxide, which offered similar properties at a lower cost. This competition forced many factories to adapt or risk closure This competition forced many factories to adapt or risk closure This competition forced many factories to adapt or risk closure This competition forced many factories to adapt or risk closurepigment lithopone factories. Some chose to specialize in niche markets where lithopone's unique characteristics were highly valued, while others focused on improving their production processes to reduce costs. Sachtleben's journey into the world of TiO2 production began with a clear vision to manufacture high-performance pigments that not only meet but exceed industry standards. Their commitment to excellence is evident in the rigorous processes employed at their state-of-the-art facilities. Using cutting-edge technology, they have refined the traditional chloride process for producing TiO2, ensuring unparalleled purity and consistent color strength in their products.

Over the last several years, nanoparticles have come under scrutiny for adverse health effects. Nanoparticles are ultrafine particles between 1 to 100 nanometers in diameter. (To put this in perspective, the average human hair is around 80,000 nanometers thick.) Because of their size, which can be engineered and manipulated at the atomic or molecular level, nanoparticles exhibit unique physical, chemical, and biological properties. Titanium dioxide is one of the most commonly produced nanoparticles in the world.

On the other hand, titanium dioxide is a synthetic mineral that is produced through a chemical reaction involving the mineral ilmenite or rutile. It is used in industries such as cosmetics, paint, and sunscreen as a whitening agent and pigment. The manufacturing process of titanium dioxide involves extracting the mineral from ores, purifying it through chemical processes, and then grinding it into a fine powder.


In 2021, the European Food Safety Authority concluded that titanium dioxide is no longer safe in foods due to the same concerns over nanoparticles. As a result, titanium dioxide is now banned as a food additive in the EU. Although studies have shown that the absorption of ingested titanium dioxide is low, evidence suggests that titanium dioxide nanoparticles can accumulate in the body over time. Health Canada deemed it safe in 2022 but noted concerns. Unlike their European counterparts, Canadian officials did not consider studies performed with titanium dioxide nanoparticles alone.

Prof Maged Younes, Chair of EFSA’s expert Panel on Food Additives and Flavourings (FAF), said: “Taking into account all available scientific studies and data, the Panel concluded that titanium dioxide can no longer be considered safe as a food additive . A critical element in reaching this conclusion is that we could not exclude genotoxicity concerns after consumption of titanium dioxide particles. After oral ingestion, the absorption of titanium dioxide particles is low, however they can accumulate in the body”. 

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 author thanks Marco Leona, Scientist-in-Charge of the Department of Scientific Research at the Metropolitan Museum of Art for conducting fluorescence spectrometry on Wheel of Fortune and a valuable discussion of the research, as well as Silvia Centeno, Research Scientist at the Metropolitan Museum of Art, who performed Raman analysis on the watercolors and also contributed her insight. The phenomenon of the phosphorescing lithopone was originally discovered during the author's fellowship in the Sherman Fairchild Center for the Conservation of Works on Paper, funded by the Andrew W. Mellon Foundation. The author thanks all her colleagues for their ideas and support during the research of this paper, and special thanks to Rachel Mustalish for her assistance in editing this work.

Titanium dioxide comes in the form of a white powder and is sometimes used in cosmetics to adjust a color to a lighter shade. This is also why it can produce a white cast.
