Titanium dioxide (VK-T02) strong UV resistance is due to
its high refractive index and high optical activity. Its UV resistance and
mechanism related to their size : When the particle size is large, the barrier
to ultraviolet light is reflected, scattered mainly on the medium wave and
long-wave region ultraviolet region and are valid . Sunscreen is a simple
mechanism to cover the case of general physical sunscreen , sunscreen weak ; as
the particle size decreases, the light through nano-titanium dioxide (VK-T02)
particle surface area on the long-wave ultraviolet reflection , scattering
obvious, and the ultraviolet absorption wave area significantly enhanced.
Sunscreen mechanism which absorb ultraviolet light, the main absorption wave UV
region .
Thus, titanium dioxide (VK-T02) of different wavelengths of UV sun protection mechanism is not the same , long-wave ultraviolet barrier area dominated by scattering the wave barrier to absorb ultraviolet region dominated
Titanium dioxide (VK-T02) as small size, great activity , both reflection and scattering of UV rays, but also absorb ultraviolet light , which has a stronger barrier against UV capability .
The titanium dioxide (VK-T02) is an inorganic component , has excellent chemical stability , thermal stability and non-migratory and strong achromatic power , covering power , low resistance, good ease of dispersion , and non-toxic, tasteless , non-irritating , safe to use , but also both sterilization and deodorization effect. More importantly , as mentioned above , titanium dioxide (VK-T02) both absorb ultraviolet light, but also emission , scattering of light , so the ability of UV , with the same dose as compared organic UV agents , which UV absorption peak higher ; and titanium dioxide (VK-T02) on the medium wave and long-wave region ultraviolet region have barrier effect , unlike organic UV dose zone or just a single pair of medium wave ultraviolet shielding effect of the long wavelength region . Especially due to its smaller particles , manufactures high transparency, can transmit visible light , adding cosmetics use natural skin whiteness , to overcome some organic or pigment grade titanium dioxide (VK-T02) opaque skin showing unnatural pale shortcomings.
