In October 2020 the SCCS confirmed the safety of TiO 2 in a range of cosmetic applications, including face products in loose powder form and hair aerosol spray products. In their latest opinion published on December 2023, SCCS concluded that some types of TiO₂ are subject to additional testing.
1 Μαρ 2024 · While the cosmetic industry often uses titanium dioxide in its pigment form, which consists of larger particles that cannot be inhaled, the use of nano-sized particles in products, particularly...
On the basis of safety assessment, the SCCS is of the opinion that the use of pigmentary titanium dioxide (TiO2) up to a maximum concentration of 25% in a typical hair styling aerosol spray product is not safe for either general consumers or hairdressers.
Inhalation & Cancer: The data suggests nanoized titanium dioxide can be inhaled by some mammals, leading to concerns about adverse effects of human inhalation. Existing studies have suggested TiO2 nanoparticles may be more toxic than traditional larger particles of TiO2.
13 Απρ 2018 · Titanium dioxide can be both safe and unsafe, depending on its use. When inhaled, titanium dioxide is considered possibly carcinogenic to humans. This means that in products that contain powdered titanium dioxide like loose powders, pressed powders, eyeshadows, and blushes in which the makeup is in powder form, titanium dioxide can be inhaled.
A study assessed the nano-TiO 2 distribution after topical application to the dorsal skin of hairless rats for 56 days. 28 Nano-TiO 2 was detected in the stratum corneum layer of the epidermis and follicular epithelium, but not in the viable skin areas.
18 Αυγ 2020 · The SCCS’s preliminary opinion concluded that use of pigmentary TiO2 up to a maximum concentration of 25% was safe in make-up applications as a loose powder. However, it concluded that use at these concentrations in aerosol sprays for general consumers or hairdressers was not safe.
