It is in rutile crystal structure and coated with silica or/and alumina to prevent photocatalytic phenomena. 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. However titanium dioxide is a known carcinogen. [2]
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 ...
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 California Food Safety Act was colloquially referred to as the “Skittles ban” before its passage because an earlier version of the bill also targeted titanium dioxide, which is used to ...
A 2021 report from the California Office of Environmental Health Hazard Assessment found that kids who have food dyes, including red dye No. 3, can become more hyper than usual and have difficulty ...
[9]: v–ix, 33–35 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 specific to TiO 2 but primarily related to particle size and surface area. [10]: v–vii, 73–78

Some researchers argue that the risk of sun-induced skin cancer outweighs concerns about toxicity and mutagenicity, [43] [44] although environmentalists say this ignores "ample safer alternatives available on the market containing the active ingredient minerals zinc oxide or titanium dioxide", which are also safer for the environment.
