The FDA and certain others say titanium dioxide is safe to use in foods and personal care products. The FDA provides strict guidelines on how much can be used in food. The limit is very small: no more than 1% titanium dioxide.
Titanium dioxide R-996 is mainly used in powder coatings, water-based and solvent-based external coatings, high-grade color masterbatches, plastics, rubber, inks, high-grade paper and wax paper and leather upholstery fabrics, cosmetics, suitable for high-grade interior coatings, high-solid paints, Road marking paints, marine paints and inks, and also used in the plastics, rubber, paper and leather industries.
It is a white crystalline powder, which is a mixture of zinc sulfide and barium sulfate. The more zinc sulfide it contains, the stronger the hiding power and the higher the quality. The density of lithopone is 4.136~4.34/cm3 and it is insoluble in water. It easily decomposes when exposed to acid to produce hydrogen sulfide gas, but does not work when exposed to hydrogen sulfide and alkaline solutions.

In cosmetics, titanium dioxide’s properties enhance coloration and can help protect skin from damaging UVA and UVB rays.

But what is titanium dioxide, exactly? Here's what you need to know about this popular food additive — including what products it's used in and whether it's safe to consume.
Skittles has been making headlines in recent weeks and not because a new flavor has been added to the popular taste the rainbow candy.
Nanotoxicology “focuses on determining the adverse effects of nanomaterials on human health and the environment.”
In sunscreen, titanium dioxide is used as a barrier to keep the sun's ultraviolet (UV) rays from damaging your skin. It's processed into much smaller particles than what goes into food, called nanoparticles. In this form, it becomes transparent, and also absorbs UV light so it doesn't reach your skin.
Some consumer advocacy groups and health agencies — particularly, those at the Environmental Working Group — have been pushing federal officers at the Food and Drug Administration (FDA) to reconsider their existing rules on the additive, which is commonly found in processed snacks and sweets.
