Another approach utilizes titrimetry, where a standard solution of a titrant, such as lead perchlorate or barium perchlorate, is used to react with the sulfate ions. The endpoint of the titration is determined either by a color change indicator or more sophisticated instrumentation like a potentiometric titrator The endpoint of the titration is determined either by a color change indicator or more sophisticated instrumentation like a potentiometric titrator

At the present JECFA meeting, the committee considered additional toxicological studies relevant to the safety assessment of the chemical that investigated its toxicokinetics, acute toxicity, short-term toxicity, long-term toxicity and carcinogenicity, genotoxicity, and reproductive and developmental toxicity, as well as special studies addressing its short-term initiation/promotion potential for colon cancer. The experts acknowledged that a large number of toxicological studies have been conducted using test materials, including nanoparticles, having size distributions and physico-chemical properties not comparable to real-world uses of titanium dioxide as a food additive. The studies on non-representative materials were evaluated by JECFA, but the committee concluded that such studies are not relevant to the safety assessment of the additive.

In 2023, California and New York proposed banning several food additives that are banned in Europe but legal in the United States. Titanium dioxide was among the five proposed to be banned, but in September, the additive was removed from the list of additives from the California ban list.
In conclusion, titanium IV oxide is a versatile compound that is used in a wide range of industries. From sunscreen to paints to food coloring to pharmaceuticals, titanium dioxide plays a vital role in many products. Its unique properties, such as UV protection, brightness, and stability, make it an essential ingredient in various applications. As technology continues to advance, titanium IV oxide will likely continue to play a key role in the manufacturing of innovative products.
In their role as risk managers, the European Commission and Member States will now reflect on EFSA’s scientific advice and decide upon any appropriate regulatory measures or advice for consumers.
