As for titanium dioxide, the FDA approved titanium dioxide for use as a food additive in 1966. The last time the agency reviewed the additive’s safety, according to the Guardian, was in 1973.
As a food additive, titanium dioxide and its nanoparticles in particular have been associated with DNA damage and cell mutations, which in turn, have potential to cause cancer. When used as a food coloring, it is known as E171.
A review published in 2022 in the journal NanoImpact evaluated the latest research related to genotoxic effects of titanium dioxide through in vivo studies and in vitro cell tests. Researchers summarized the results by stating TiO2 nanoparticles “could induce genotoxicity prior to cytotoxicity,” and “are likely to be genotoxic to humans.”
Factory quotations vary based on purity levels, particle size distribution, and the end-use industry Factory quotations vary based on purity levels, particle size distribution, and the end-use industrybarium sulfate quotation factories. For instance, the medical sector requires high-purity barium sulfate for contrast agents, while the oil drilling industry may opt for less pure grades.
