In 2019, EFSA published a statement on the review of the risk related to the exposure to food additive titanium dioxide (E171) performed by the French Agency for Food, Environment and Occupational Health Safety (ANSES). In its statement, EFSA highlighted that the ANSES opinion reiterated the uncertainties and data gaps previously identified by EFSA and did not present findings that invalidated the Authority’s previous conclusions on the safety of titanium dioxide.

One of the most significant impacts of TIO2 in factories is its role in photocatalysis. This process involves the acceleration of photoreaction in the presence of light and a catalyst—in this case, TIO2. By harnessing the power of sunlight or artificial UV light, TIO2 can break down organic pollutants into substances, playing a crucial role in environmental remediation efforts within industrial settings. This not only helps factories minimize their environmental footprint but also reduces the costs associated with waste treatment and disposal.
