Australia and New Zealand review of TiO2

Because of its ability to absorb UV light, it's particularly useful as an ingredient in sunscreens — while its light-scattering properties are great for applications that require white opacity and brightness, such as in paint and paper.

In 2016, the European Food Safety Authority, or EFSA, assessed titanium dioxide and determined that the evidence available at the time didn’t conclusively point to any health problems for consumers. 

Titanium dioxide (E171) is an additive that is used in food as a colour. The function of food colours is to make food more visually appealing, to give colour to food that would otherwise be colourless, or to restore the original appearance of food. Titanium dioxide is used to provide whiteness and opacity to foods.
