Titanium dioxide, also known as titanium(IV) oxide or titania / t aɪ ˈ t eɪ n i ə /, is the inorganic compound derived from titanium with the chemical formula TiO 2. When used as a pigment, it is called titanium white, Pigment White 6 (PW6), or CI 77891. [4] It is a white solid that is insoluble in water, although mineral forms can appear ...
Titanium dioxide is in food, cosmetics, dye, tampons. Some worry it causes cancer, irregular periods. Doctors say there's no link between cancer titanium dioxide.
No reports of actual adverse health effects in workers using or producing these nanomaterials were known as of 2013. [20] Titanium dioxide (TiO 2 ) dust is considered a lung tumor risk, with ultrafine (nanoscale) particles having an increased mass-based potency relative to fine TiO 2 , through a secondary genotoxicity mechanism that is not ...
The health risks of ultrafine TiO 2 from dermal exposure on intact skin are considered extremely low, [1] and it is considered safer than other substances used for ultraviolet protection. Nanosized particles of titanium dioxide tend to form in the metastable anatase phase, due to the lower surface energy of this phase, relative to the ...
Some people get nervous because the titanium dioxide in paints gives it a bad rap. The CDC’s National Institute for Occupational Safety and Health does say ultrafine titanium dioxide is a ...

The health and safety hazards of nanomaterials include the potential toxicity of various types of nanomaterials, as well as fire and dust explosion hazards. Because nanotechnology is a recent development, the health and safety effects of exposures to nanomaterials, and what levels of exposure may be acceptable, are subjects of ongoing research.
Mineral ingredients, which include zinc oxide and titanium dioxide, are also referred to as physical sunscreens; these “block harmful ultraviolet damage by sitting on the skin,” says Dr. Mona ...
