titanium dioxide used in plastic manufacturer

The primary function of titanium dioxide in paint is its ability to provide superior opacity. By effectively hiding the underlying surface, it allows fewer coats of paint to achieve the desired color intensity and uniformity. This not only reduces material costs but also shortens application time, making it an economical choice for paint manufacturers. Additionally, titanium dioxide's refractive index contributes to the brightness and cleanliness of the paint film, ensuring that colors remain vibrant and true over time.

Scientists analyzed research that examined how titanium dioxide nanoparticles interact with the brain for a 2015 review published in Nanoscale Research Letters. The researchers wrote: “Once the TiO2 NPs are translocated into the central nervous system through [certain] pathways, they may accumulate in the brain regions. For their slow elimination rates, those NPs could remain in the brain zones for a long period, and the Ti contents would gradually increase with repeated exposure.” After reviewing dozens of studies, the scientists concluded: “Long-term or chronic exposure to TiO2 nanoparticles could potentially lead to the gradually increased Ti contents in the brain, which may eventually induce impairments on the neurons and glial cells and lead to CNS dysfunction as a consequence.”
