In 21st century, for the worst enemy to human being especially to women is the ultraviolet radiation. People have higher requirements on the safety of sunscreen products nowadays. And the inorganic sunscreen nano TiO2 powder and nano ZnO powder are non-toxic, tasteless, non-decomposing, non-degenerative, and have strong ability to absorb ultraviolet and popular. For TiO2 and ZnO would be the smart choice for anti UV.

Nano Titanium Dioxide particle because of its excellent chemical stability and light stability, non-toxic harmless is widely used in various types of sunscreen, skin care, cosmetics and other cosmetics. For nano TiO2 powder UV range is medium and long wavelengths. It not only absorbs ultraviolet light, but also reflects or scatters ultraviolet light.

For the nano zinc oxide particles less than 100nm with excellent absorbs ultraviolet ability. It is because the nano ZnO powder has a quantum size effect. ZnO nano powder will absorbs a specific wavelength of light with a blue-shift phenomenon and the absorption of various wavelengths of light with a broadening phenomenon. So the nano ZnO powder has a strong shielding effect in a wide UV range.

Specifically, the titanium dioxide absorption wavelength from 290 nm to 355 nm  ultraviolet effect is stronger. Therefore, compared with zinc oxide, titanium dioxide inhibit melanin effect is stronger, and make the skin whitening effect is best.Zinc oxide is better than titanium dioxide in absorption wavelength from 355 nm to 385 nm.

Different wavelengths of ultraviolet radiation damage to human body:
