The FDA first approved the use of titanium dioxide in food in 1966, following its 1960 removal (along with the removal of other color additives) from the agency's original Generally Recognized as Safe list. In 1977, titanium dioxide joined the list of color additives that are exempt from certification, which means titanium dioxide doesn't have to be listed on the packaging of every product it's used in, Faber noted.

When E171 isn’t combined with other ingredients and administered in water, some studies suggest that under these artificial conditions, E171 may be processed differently in the body resulting in some biological changes in experimental animals that are poorly understood.

‌If you're curious about whether something you’re eating contains titanium dioxide, you can check the ingredients list. But know that the FDA doesn’t require food makers to use its chemical name on an ingredients list. Instead, it could be listed as:

FDA’s response

Magnesium can be made by several methods (Fig. 1), but the most common method of manufacture is by the electrolytic process, as for example the electrolysis of magnesium chloride.

Yesterday, some parts of the domestic rutile, anatase titanium dioxide new single price to maintain stability, titanium dioxide factory normal, more delivery of early orders, spot shipping pressure is small; And the buyer just needed to buy a few days ago. Downstream manufacturers are currently watching the latest execution price.The key factors affecting the current market price change1. Inventory: Low inventory of mainstream producers, mainly delivery of pre-contract orders, is expected today's spot inventory is still low, mainstream factories before the holiday spot tension.2. Mentality: the buyer has to prepare goods in advance, and the new order price is slightly less willing to purchase in bulk; Sellers due to the lack of inventory, manufacturers have no willingness to reduce the price of sales in the market of new orders just need to buy more.Trend: The load of titanium dioxide enterprises is stable, the willingness to ship at low prices is not strong, and the downstream buyer's early orders continue to digest, and the acceptance of the purchase before the holiday is acceptable. It is expected that the market of titanium dioxide just needs to be closed today, and it is concerned about the new execution price of the mainstream factory.

A  2023 study published in the journal Environmental Research, scientists examined the effect of titanium dioxide nanoparticles on important gut bacteria in mice. Their results showed “the growth inhibitory effects could be associated with cell membrane damage caused by titanium dioxide nanoparticles to the bacterial strains. Metabolomics analysis showed that TiO2 NPs caused alterations in multiple metabolic pathways of gut bacteria, such as tryptophan and arginine metabolism, which were demonstrated to play crucial roles in regulating gut and host health.” The researchers also found that four different neuroprotective metabolites “were significantly reduced” in urine and in vitro bacteria and vivo urine samples. The researchers concluded: “Increasing evidence implies that the gut microbiome plays a profound role in regulating host metabolism. Our results illustrated that TiO2 NPs hindered the growth of four beneficial gut bacterial strains.”

One of the key advantages of using titanium dioxide in rubber is its ability to enhance the whiteness and brightness of rubber products. This is especially important in applications where aesthetic appeal is a priority, such as in the manufacturing of white or light-colored rubber goods. The high opacity of titanium dioxide allows for better hiding power, ensuring a uniform and attractive finish on rubber surfaces.
