The Secret of Sun Cream—Titanium Dioxide (7/10/2016)
There are many substances are white in the world, for example, the snow and cotton. However, people barely know the whitest substance in this world—Titanium Dioxide.
The relevant data delineates that one gram of Titanium Dioxide could cover more than 450 square centimetres, and it is even 5 times whiter than lithopone. Today, Titanium Dioxide has already been widely used within industrial, food, environmental sectors and its presence in cosmetics area is showing an upward trend. The relevant research shows that the sunblock effectiveness of sun cream with Titanium Dioxide is 100 times better than the normal sun cream.
The main reason for Titanium Dioxide’s excellent UV resistance is that Titanium Dioxide has high level of refractivity and its gran size. When the nanoscale Titanium Dioxide was used in the sun cream, the Ultraviolet Ray can not only be reflected, but also absorbed. This is also the reason why sun cream was divided into 10+, 30+ and 50+ different level of SPF.
