anhydrous
Lacking all moisture
Anhydrous means containing no water.
The term appears mainly in chemistry to describe compounds from which water has been removed or that naturally lack water molecules: anhydrous ammonia, anhydrous ethanol.
Anhydrous forms of substances often behave differently from their hydrated counterparts and may react vigorously when water is introduced.
