Earlier this year, a bill was introduced in the California legislature to ban the manufacture, sale and distribution of foods in the state containing titanium dioxide, along with four other harmful food chemicals. 

When asked about the recent Skittles lawsuit, the FDA said the agency does not comment on pending litigation.

Moreover, titanium dioxide is also used in rubber formulations to improve the processing and curing properties of rubber compounds. It acts as a catalyst in the vulcanization process, speeding up the cross-linking of rubber molecules and enhancing the overall performance of the final product. This results in rubber products that are stronger, more flexible, and better suited for a wide range of applications.
