Product Detail
China Manufacturer Cosmetics Used Anti-UV Titanium Dioxide TiO2 Nanopowder
Specification of TiO2 nanopowder for cosmetics:
Particle size: <10nm
Type: Anatase
Purity: 99.9%
Other size & type: 30-50nm, rutile
Working principle of Nano TiO2 in anti-UV:
1. When exposed to ultraviolet light, the electrons on the valence band are absorbed by the ultraviolet rays and are excited to the conduction band, and at the same time produce holes electron pairs, and therefore have the function of absorbing ultraviolet light
2. In addition, the nano titanium dioxide size is much smaller than the wavelength of ultraviolet light, the nanoparticles can be used in the UV rays scattered in all directions, thereby reducing the direction of the UV radiation, the law of scattered ultraviolet light Ray Ray light law.
