According to the classification of ultraviolet wavelengths

According to the classification of ultraviolet wavelengths, can be divided into ultraviolet A (wavelength 320 400nm), ultraviolet B (wavelength 290 ~ 290nm) and ultraviolet C (wavelength 200 290nm), so the ultrafine powder material is the preferred choice of filtering the solar UV damage, nano titanium dioxide can help scattering ultraviolet A and ultraviolet B in order to protect the skin from harm.

Up to 25% nanometer titanium dioxide sunscreen (mass percentage), about 70% of the sunscreen use nanometer titanium dioxide. In 2015 the global sun care market size of $9 billion 800 million, of which 65% is sun protection products, the other is sun repair products.
Paint and coatings

In 2015 the global paint and coatings in the field of nano titanium dioxide market value of about $56 million 800 thousand, in 2020 is expected to grow to $99 million 500 thousand, a compound annual growth rate of nearly 12%. The application of nano titanium dioxide materials in the paint and coatings industry is significantly increased, to add to produce pigment from cleaning and decontamination function etc..

Rutile nano titanium dioxide is more stable than anatase titanium dioxide nano materials, so the former is outdoor paint and paint products preferred anatase pigment, however the material cost is low, so it can be used for indoor coating products.
