Demand in the European region has been significantly boosted by higher offtakes in the furniture, building, and industrial sectors compared to Q2, after a boost in containment measures. DIY activities increased significantly as people engaged in more home renovation and building tasks during the extended period of lockdown. With the restart of Chinese shipments in the latter half of Q2 2020, supply has also remained plentiful.
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.
While the conclusions of the EU expert panel were considered in this report, Health Canada's Food Directorate conducted its own comprehensive review of the available science. This included evaluating new scientific data that addressed some of the uncertainties identified by the EU expert panel and were not available at the time of their review.
When it comes to sourcing titanium dioxide, it is essential to understand the various processes involved in its production. The two primary production methods are the sulfate process and the chloride process. The sulfate process tends to be more cost-effective in certain contexts, but it also generates a substantial amount of waste, putting pressure on manufacturers to invest in waste treatment technologies. On the other hand, the chloride process is known for its superior quality and lower environmental impact, albeit at a higher production cost.

Anyway, it doesn't matter if it reflects or absorbs, Titanium Dioxide is a pretty awesome sunscreen agent for two main reasons: it gives a nice broad spectrum coverage and it's highly stable. Its protection is very good between 290 - 350 nm (UVB and UVA II range), and less good at 350-400 nm (UVA I) range. Regular sized Titanium Dioxide also has a great safety profile, it's non-irritating and is pretty much free from any health concerns (like estrogenic effect worries with some chemical filters).
As a food additive, titanium dioxide and its nanoparticles in particular have been associated with DNA damage and cell mutations, which in turn, have potential to cause cancer. When used as a food coloring, it is known as E171.
The production of Chinese anatase titanium dioxide involves a series of complex chemical processes, including hydrolysis and calcination of titanium precursors. These processes result in the formation of nanoscale particles of anatase titanium dioxide, which exhibit enhanced properties such as increased surface area and improved reactivity. The size and morphology of these nanoparticles can be controlled during the synthesis process, allowing for the production of tailored materials with specific properties for different applications.

Calcium carbonate and titanium dioxide are two important minerals that are widely used in various industries. While they share some similarities, they also have distinct differences when it comes to their manufacturing processes and applications.
