- Titanium dioxide, or TiO2, is a versatile material known for its exceptional refractive index, UV absorption, and photocatalytic activity. When produced in the nano range, specifically 30-50nm, these characteristics are amplified, opening up a world of possibilities. The 30-50nm TiO2 powders are widely used in applications such as sunscreens, self-cleaning surfaces, air purification systems, and even water treatment technologies due to their superior photocatalytic performance.

- 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 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.
The paints and coatings industry reduced their offtakes which coupled with the drop in the crude oil prices and availability of cheaper imports from the Asian market led to the fall in titanium dioxide prices. The demand decreased significantly in the fourth quarter along with the slow manufacturing due to high inflation rates keeping the price trends of the commodity in the negative zone.


Absorption
Mars Wrigley, the company that makes Skittles, is being sued by a California man who claims the candy contains a known toxin that poses such a serious health risk that Skittles are unfit for human consumption.
Comparisons
For years scientists have raised concerns about the potential toxicity of titanium dioxide.
The agency makes this exception for several approved color additives.
Suppliers of Barium Sulphate
The additives that received a “no safety concern” conclusion based on current estimated dietary exposure are as follows:
Wegman’s puts titanium dioxide in its Original Macaroni and Cheese. Campbell’s Healthy Request Chunky Chicken Corn Chowder has it, as does Food Club’s Chunky New England Clam Chowder. Marzetti uses the color agent to brighten its Cream Cheese Fruit Dip. Dairy products usually don’t need titanium dioxide to look white, but Kroger has decided to add titanium dioxide to its Fat Free Half-and-Half. And titanium dioxide isn’t only in especially white or brightly colored foods: Little Debbie adds it to Fudge Rounds and many other products. According to the Food Scores database maintained by Environmental Working Group, more than 1,800 brand-name food products have titanium dioxide on their ingredients list. That said, it can still lurk as an unspecified “artificial color,” or labels might simply say “color added.”
