Mica Powder Without Titanium Dioxide-How Long Does Titanium Dioxide Stay In Your System

Titanium dioxide (TiO2) is commonly used as a pigment in paints, plastics, and cosmetics, and as a food additive (E171). When ingested, the absorption of titanium dioxide in the human body is generally low. Most of it passes through the gastrointestinal tract and is excreted in the feces.

For those particles that are absorbed, the exact duration that titanium dioxide stays in the system can vary based on several factors, including the form of the titanium dioxide, the amount ingested, and individual metabolic differences. However, studies suggest that the half-life of titanium dioxide in the body can range from a few days to a few weeks.

It’s important to note that while the majority of titanium dioxide is considered safe, there have been concerns about the potential health effects of nano-sized titanium dioxide particles, which may have different properties and could potentially lead to different retention times and biological effects.

If titanium dioxide is inhaled as dust, it can remain in the lungs for a longer period, potentially leading to respiratory issues if exposure is chronic and at high levels.

For specific medical advice or concerns about titanium dioxide exposure, it is best to consult with a healthcare professional. They can provide more detailed information based on the particular circumstances of exposure.
