A 2012 study published in the journal Environmental Science & Technology noted that children are especially exposed to titanium dioxide because of the food that contains the food additive and is particularly marketed to children, including candy and cakes.

What does titanium dioxide do? 

In recent years, there has been growing interest in the development of novel applications for Chinese anatase titanium dioxide, such as in the field of energy storage and conversion. For example, it has been investigated as a potential electrode material for lithium-ion batteries, due to its high conductivity and stability. Furthermore, its photocatalytic activity has been explored for use in dye-sensitized solar cells, where it can help to improve the efficiency of solar energy conversion.
