(organic compound) A white transparent waxy crystalline isoprenoid ketone, 1,7,7-trimethylbicyclo[2.2.1]heptan-2-one, with a strong pungent odour, used in pharmacy.
a small ball of chemical pesticide and deodorant placed in or around clothing and other articles susceptible to damage from mold or moth larvae in order to protect them from this damage; mothballs have either naphthalene or paradichlorobenzene as their active ingredient.
A tough, white, aromatic resin, or gum, obtained from different species of the Laurus family, esp. from Cinnamomum camphara (the Laurus camphora of Linnæus.). Camphor, C10H16O, is volatile and fragrant, and is used in medicine as a diaphoretic, a stimulant, or sedative.
(transitive) To store or shelve (something no longer used).
‘They mothballed the old version after the new one came out.’;
originally, a gum resembling ordinary camphor, obtained from a tree (Dryobalanops aromatica formerly Dryobalanops camphora) growing in Sumatra and Borneo; now applied to its main constituent, a terpene alcohol obtainable as a white solid C10H18O, called also Borneo camphor, Malay camphor, Malayan camphor, camphor of Borneo, Sumatra camphor, bornyl alcohol, camphol, and borneol. The isomer from Dryobalanops is dextrorotatory; the levoratatory form is obtainable from other species of plants, and the racemic mixture may be obtained by reduction of camphor. It is used in perfumery, and for manufacture of its esters. See Borneol.
(transitive) To stop using (something), but keep it in good condition.
To impregnate or wash with camphor; to camphorate.
A small sphere of camphor or naphthalene used to keep moths away from stored clothing.

To put into long-term storage; as, to mothball the battleships not needed after the war.
Camphor () is a waxy, flammable, transparent solid with a strong aroma. It is a terpenoid with the chemical formula C10H16O. It is found in the wood of the camphor laurel (Cinnamomum camphora), a large evergreen tree found in East Asia; and in the related kapur tree (Dryobalanops sp.), a tall timber tree from South East Asia.
