The Scientific Committee on Consumer Safety issued an opinion of the safety of titanium dioxide in food, stating that it should no longer be considered as safe when used as a food additive.

To put this all into context maybe we should go back to the beginning & Bluescope steel who make all of our lovely Australian colour bond iron roofs.

The annual production capacity of high-grade rutile titanium dioxide has reached more than 400,000 tons. It is one of the largest TiO2 manufacturers in China at present. It has more than ten product brands of Taiohua, Jinxing and other brands, and its products are sold in more than 50 countries and regions around the world. It has long maintained the excellent performance of the second overall ranking in the domestic titanium dioxide industry.

The updated evaluation revises the outcome of EFSA’s previous assessment published in 2016, which highlighted the need for more research to fill data gaps.

Currently, the development of TiO₂ memristors is associated with their use in modern highly technological applications, such as resistive random-access memory (RRAM), biohybrid systems, and sensors, as schematically shown in Figure 1A. In this mini-review, we briefly outline and summarize the key milestone achievements, as well as recent advances in the synthesis, fabrication, and application of TiO₂-based memristors. A special focus is placed on the relationships between the synthesis and deposition methods, the effects of post-synthesis treatment, and the resistive switching properties.
