Definition - What does Desiccant mean?

A Desiccant is a hygroscopic substance which has the ability to sustain or induce a state of dryness in its proximity. The commonly detected Desiccants are the solids which absorb water. They can also be in other forms other than solid and may work on other principles like the chemical bonding of water molecules. They are generally used in certain foods to retain their crispness. They are also used for removing water from solvents that are typically needed by chemical reactions which do not tolerate water.

Petropedia explains Desiccant

There are various substances that are capable of soaking water from the surrounding but only a few of them can be used practically and very few are readily available for the average person. One example is a Desiccant, which is a substance that promotes drying. Desiccants are typically used in shipping containers to protect goods against moisture damage. They are used in industries for controlling the level of water in gas streams. They come in many forms and are used widely in the pharmaceuticals, electronics, foods, packing and various manufacturing industries. Air conditioning systems are made depending on Desiccants.
