Matthew Wright, chair of the authority's working group on titanium dioxide, noted that the evidence for general toxic effects was not conclusive, but that the panel couldn't rule out genotoxicity entirely. There were also some current data limitations and the assessment could not establish a safe level for daily intake of the food additive, he stated.

One of the key challenges facing TiO2 industry suppliers is the fluctuation of raw material prices. The production of TiO2 requires raw materials such as ilmenite or rutile, which are subject to market price volatility. Suppliers must carefully monitor these fluctuations and adjust their production processes accordingly to ensure profitability.
