desiccant
/ˈdɛsɪk(ə)nt
/noun
A hygroscopic substance used as a drying agent: natural desiccants cause fleas to dehydrate and die [mass noun]: a small packet of desiccant to absorb any moisture...
- However, desiccants contain chemical agents that may be toxic to children, pets, and the chemically sensitive.
- Unlike cooling-based dehumidifiers, which cool the air to condense moisture, desiccants attract moisture molecules directly from the air and release them into an exhaust air stream.
- One ingredient found in almost all tablet or capsule containers is a desiccant - cotton batten or a small canister containing a harmless, water-absorbing compound.
Origin
Late 17th century: from Latin desiccant- 'making thoroughly dry', from the verb desiccare.
