In a 2016 study published in Scientifica (Cairo), Egyptian researchers examined the effects of titanium dioxide nanoparticles on the organs of mice by orally administering the food additive daily, for five days. The results showed that the exposure produced “mild to moderate changes in the cytoarchitecture of brain tissue in a time dependent manner.” Furthermore, “Comet assay revealed the apoptotic DNA fragmentation, while PCR-SSCP pattern and direct sequencing showed point mutation of Presenilin 1 gene at exon 5, gene linked to inherited forms of Alzheimer’s disease.” The researchers wrote: “From these findings, “the present study concluded that TiO2NPs is genotoxic and mutagenic to brain tissue which in turn might lead to Alzheimer’s disease incidence.”
- In conclusion, titanium dioxide's in oil factories is a testament to its versatility and utility in the industrial domain. From improving the performance of drilling fluids to enhancing the durability of refinery coatings, TiO2 is a critical component in the oil industry's pursuit of efficiency, safety, and sustainability. As technology advances, the potential applications of this remarkable compound are likely to expand even further, solidifying its position as an indispensable element in oil manufacturing processes.

This route affords a product that is 29.4 wt % ZnS and 70.6 wt % BaSO4. Variations exist, for example, more ZnS-rich materials are produced when zinc chloride is added to the mixture of zinc sulfate and barium sulfide.
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.
In a 2017 study published in Scientific Reports, researchers exposed rats to human-relevant levels of E171 to examine the effects of intestinal inflammation and carcinogenesis. They saw that “a 100-day E171 treatment promoted colon microinflammation and initiated preneoplastic lesions while also fostering the growth of aberrant crypt foci in a chemically induced carcinogenesis model.” They continued: “Stimulation of immune cells isolated from Peyer’s Patches [which are clusters of lymphoid follicles found in the intestine] showed a decrease in Thelper (Th)-1 IFN-γ secretion, while splenic Th1/Th17 inflammatory responses sharply increased,” researchers wrote. “A 100-day titanium dioxide treatment promoted colon microinflammation and initiated preneoplastic lesions.” The scientists concluded: “These data should be considered for risk assessments of the susceptibility to Th17-driven autoimmune diseases and to colorectal cancer in humans exposed to TiO2 from dietary sources.”
6. What happens next?
Why all of a sudden is there so much interest in the safety of Titanium Dioxide?
Researchers from France and Luxembourg gave E171 (the much more food friendly name for Titanium Dioxide) in Europe and the United States, to lab rats in their drinking water for 100 days.
Of those rats, 40 per cent of the exposed rodents developed “preneoplastic lesions” or precancerous growths. The Titanium Dioxide also inhibited the immune systems of the rats and “accelerated” the growth of the lesions. France’s INRA agricultural research institute, which took part in the study, said in a statement.“These results demonstrate a role in initiating and promoting the early stages of colorectal cancer formation,” though it said no conclusion could be drawn about later phases of cancer, or of any danger to humans……….(not till they test it on us!!)
The results of the study were published in the Nature journal Scientific Reports.
Topical Exposure
What Is Titanium Dioxide?
A safety review conducted by the EFSA in 2021 assessed thousands of studies published on titanium dioxide.
It’s particularly useful in sunscreen as it has impressive UV resistance and helps block the sun’s UVA and UVB rays from reaching your skin (6Trusted Source).
It should also be considered that due to the low pH in the stomach, the increased dissolution of the TiO2 particles may increase its bioavailability and may facilitate the entry of titanium ions into the blood circulation. Despite the relatively large consumption of TiO2 as a food additive, no studies on the effect of pH on its absorption and bioavailability have been found in the literature. This can be attributed to a general belief that TiO2is completely insoluble. However, this is not completely true, as TiO2 particles show a certain degree of solubility.
