The component can be both safe and unsafe. It’s reported to be possibly carcinogenic to humans when inhaled. That’s why we don’t recommend using products where TiO2 is used in the form of powder and can be inhaled.
Sometimes it can be a nanoparticle. We recommend avoiding this form because it’s not researched well enough. A safer option is to use a non-nano form.
