French researchers studied how and where E171 nanoparticles enter the bloodstream, first studying the route through pigs and then in vitro with human buccal cells, for a 2023 study published in the journal Nanotoxicology. The research showed that the nanoparticles absorbed quickly through the mouth and then into the bloodstream, before damaging DNA and hindering cell regeneration.
Ref 1:1 What is titanium dioxide made of?
The so-called “barrier effect” makes it possible to achieve good anti-corrosion protection in primers.


The photocatalytic properties of TiO 2 are used in modern technologies. Photo catalysis is the acceleration of a chemical reaction under the influence of light (UV radiation, visible radiation, infrared) in the presence of a photocatalyst. Titanium white appropriately ground to the size of nanoparticles has unique photocatalytic properties and can get from rutile titanium dioxide supplier.

In a study published in the journal Food and Chemical Toxicology in 2016, researchers investigated whether titanium dioxide exposure led to an increase in colorectal tumor creation in mice by using a colitis associated cancer model. By measuring tumor progression markers, the researchers found that mice given titanium dioxide experienced enhanced tumor formation in the distal colon. There was also a decrease of cells that act as a protective barrier in the colon. The researchers wrote: “These results suggest that E171 could worsen pre-existent intestinal diseases.”

The production of ROS was studied on white blood cells as a model to screen the effect on eukaryotic cells after being exposed to samples and solar simulated irradiation (according to the level of penetration under the skin). For that purpose, the leukocytes were separated from anticoagulated fresh blood using the Ficoll-Hypaque reactive in a well-known technique [33]. Then, 50 μL of suspensions of P25TiO2NPs (0.2 mg/mL and 0.02 mg/mL), vitaminB2@P25TiO2NPs (0.2 mg/mL and 0.02 mg/mL) and vitamin B2 (0.2 mg/mL and 0.02 mg/mL) were prepared and mixed with 50 μL of white blood cells suspension. A solution of 3% H2O2 was used as positive control and PBS as negative control. Then, the samples were irradiated using the LED panel for 3 and 6 h to simulate the light penetration into the skin. Also, a set of samples was kept in the dark as control. Finally, the ROS were detected through the colorimetric assay employing the nitroblue tetrazolium salt (NBT salt) and the absorbance at 650 nm was measured. The experiment was reproduced twice; the standard deviation was calculated and p-value < 0.05 were considered significant.
Another important factor to consider when choosing r 996 titanium dioxide suppliers is their reliability and consistency in supply
. Having a supplier that can consistently deliver the required quantities of the product on time is crucial for maintaining smooth operations in various industries. r 996 titanium dioxide suppliers have built a reputation for their reliability and timely delivery of products, making them a preferred choice for many businesses.r 996 titanium dioxide suppliers

5. Regulatory compliance The MSDS should also include information on regulatory requirements for the safe handling and use of lithopone, including any permits or certifications that may be necessary.

So if you’re worried about titanium dioxide, don’t be! With current research and industry recommendations, titanium dioxide is a safe food additive. And if you want to avoid it, that’s ok too! Just don’t expect certain foods to be so white, smooth, and bright.

A European ban of titanium dioxide in food took effect in 2022, but it is still legal for use in food in the U.S.

Going Public
How we’re exposed to an ingredient matters greatly in terms of our long-term health.
Research shows that inhaling titanium dioxide particles in significant quantities over time can cause adverse health outcomes. Unless you work in an industrial setting, inhaling substantial amounts of titanium dioxide is highly unlikely.
