used in building materials, glass, agricultural, automotive, cosmetics and other f≥ields.

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

but it is extremely difficult to dissolve in water, which limits its application in the f∑ield 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.
