Cerium is a lanthanide metal, which oxidation products - Cerium oxide has been widely 

used in building materials, glass, agricultural, automotive, cosmetics and other fields.

Cerium oxide has excellent defense ability against UVB, UVA and high-energy short wave blue light,

but it is extremely difficult to dissolve in water, which limits its application in the field of cosmetics.

JSCOS^®Basic α has achieved the uniform dispersion of cerium oxide in water by self-developed 

special processing technology for cerium oxide, and reached the nanometer level.
