Furthermore, titanium dioxide imparts excellent brightness and opacity to plastics, which is crucial for achieving a consistent, high-quality appearance. It helps to mask any impurities or irregularities within the plastic material, resulting in a more attractive and marketable product. For example, in the production of white or light-colored plastic goods like appliances, packaging materials, and toys, TiO2 ensures an even, lustrous finish that consumers find appealing.

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.”
