However, it’s also important to note that such adverse effects depend heavily on the form of the titanium dioxide. It can come down to characteristics like “particle shape, purity, surface charge, solubility, agglomeration rate, photo-activation, etc.”

The risks associated with titanium dioxide exposure depend on a variety of factors, including the form of the mineral, the route of exposure (such as being inhaled or consumed), and the duration and intensity of exposure.

Titanium dioxide is typically micronized and coated for use in cosmetics products. The micronizing makes this somewhat heavy-feeling ingredient easier to spread on skin, plus a bit more cosmetically elegant. Micronized titanium dioxide is much more stable and can provide better sun protection than non-micronized titanium dioxide.

Magnesium oxide (MgO). It is used as a curing agent and an acid scavenger in solvent-borne polychloroprene adhesives. It is a white powder with a high melting point. It has a greater ability to reflect visible light more efficiently than titanium dioxide

Titanium dioxide remains in many food products in this country because of regulatory folly by the Food and Drug Administration, which allows problematic food ingredients to remain undetected and unreviewed.
