[Character]The ingredient is silica gel, also is silicon dioxide. Chemical formula is SiO2. N H2O, harmless and non-toxic, chemical stability.
[Use] Lots of specs are available for packed silica gel, which can be put into the package of articles (including instruments, apparatus, electronic products, leather, shoes, garments, food, drug, household electric appliances, etc) to protect them from damping, mildewing, or rusting. At the same time, is currently the only FDA approved the drug in direct contact with the adsorbent.

A desiccant is a dehumidifying agent which attracts

moisture from the atmosphere. It adsorbs and holds

particles of water to itself. The three most common types

of desiccants are silica gel, clay and molecular sieve

desiccant.

Silica gel desiccant is made from amorphous silicate. It is

designed to control moisture levels within packaged

products. Under very low humidity conditions, a small

amount of water vapor will be adsorbed in the smallest

pores. As humidity increases, the large pores will begin

to fill. It remains dry and free-flowing, even at maximum

adsorption capacity.

Clay desiccants are non-hazardous, moisture adsorbent

substances created by the controlled drying of calcium

(bentonite) aluminosilicate clay. This naturally occurring

montmorillonite clay has a special affinity for moisture

and is chemically inert and non-corrosive. The layered

structure of clay desiccant attracts and adsorbs moisture

onto its surface and between its layers.
