All silica gels are hygroscopic, and respond to the relative humidity (RH) of the surrounding air in the same way as most organic materials such as paper, textiles and wood.

Silica gel can be used to remove moisture from the air, or as a humidity-buffering agent to maintain or buffer the relative humidity (RH) to a constant level. In either case, silica gel must be conditioned.
