  • 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. 

  • Barium sulfate, chemically represented as BaSO4, is a naturally occurring mineral known as barite. When processed into a superfine form, it possesses an array of benefits that extend beyond its inexpensive nature. Its fine particle size enhances its dispersibility, leading to improved performance in various applications. This superfine variant, despite its 'cheap' label, does not compromise on quality or functionality.

  • Scrap zinc or concentrated zinc ores are dissolved in sulfuric acid, the solution is purified, and the two solutions are reacted. A heavy mixed precipitate results that is 28 to 30% zinc sulfide and 72 to 70% barium sulfate.

  • The second quarter of 2022 saw mixed market sentiments for titanium dioxide prices. Due to demands, constrained supply and ineffective production capacity brought on by the stretched supply chain, labour shortage, and high energy prices, the production of the chemical increased in Q2 of 2022. Moreover, the US Federal Reserve's tight monetary policy and high interest rates worsened the domestic trade picture, which at quarter's conclusion supported titanium dioxide's unfavourable market views.

  • Another crucial property of TiO2 is that it can show photocatalytic activity under UV light. This makes it effective for environmental purification, for different kinds of protective coatings, sterilisation and anti-fogging surfaces, and even in cancer therapy.

  • The manufacturing process of titanium dioxide typically involves mining ilmenite, rutile, or anatase from natural sources, followed by conversion into TiO2 through various chemical processes. The resulting TiO2 can then be further processed to achieve different particle sizes and coatings that optimize its performance in specific applications. For instance, TiO2 used in sunscreens is often coated to enhance its effectiveness in blocking UV rays without causing skin irritation.

  • Titanium is one of the most common metals on earth, but it does not occur naturally in this elemental form. TiO2, also known as titanium (IV) oxide or titania, is the naturally occurring compound created when titanium reacts with the oxygen in the air. As an oxide, titanium is found in minerals in the earth’s crust. It is also found with other elements, including calcium and iron.

  • In response to the allegations, Justin Comes, vice president of research and development at Mars Wrigley North America, told Health that safety is of paramount importance to Mars Wrigley. While we do not comment on pending litigation, all Mars Wrigley ingredients are safe and manufactured in compliance with strict quality and safety requirements established by food safety regulators, including the FDA.

  • The composition of lithopone underscores its superiority in specific applications. Ideally, prepared lithopone consists of 30 to 32 percent sulfide of zinc, and a negligible percentage of zinc oxide (1.5%), with the remaining majority being barium sulfate. These attributes render lithopone nearly comparable to the best grades of French process zinc oxide in terms of whiteness. Furthermore, its oil absorption, which sits between lead carbonate and zinc oxide, solidifies its position as a functional and efficient white pigment.

  • However, China's Tio2 pigment industry is not without challenges
