Entering the summer, of course, the inevitable topic is sunscreen, Antan, Biore , L'Oreal , Nivea and other international brands are going to compete in the sunscreen market this summer.
Common sunscreen agents are mainly inorganic and organic sunscreens. As for inorganic sunscreen, the most common ones are titanium oxide and zinc oxide . Today, let’s talk about the research on cerium oxide CeO2 in sun protection.
Titanium oxide and zinc oxide have high reflective effects on UVA and UVB, so they are widely used.
However, due to their higher refractive index, they often feel unnatural white after use, which is what we often call "painting the wall".
As for cerium oxide , it is easy to penetrate visible light, but has good absorption of ultraviolet rays, and it also makes the skin look more natural. However, because CeO2 has a high catalytic oxidation ability for organic raw materials, this requires more sophisticated science and technology and scientific research strength to solve, thus restricting its application in sun protection.
But where there are difficulties, there are also opportunities. We believe that new cerium oxide sunscreen products can open up a new sunscreen market in the near future. Let us "cerium" wait and see!!!
