Definition of mastic. 1 : an aromatic resinous exudate from mastic trees used chiefly in varnishes.
Mastic is used in some varnishes. Mastic varnish was used to protect and preserve photographic negatives. Mastic is also used in perfumes, cosmetics, soap, body oils, and body lotion. In ancient Egypt, mastic was used in embalming. In its hardened form, mastic can be used, like frankincense or Boswellia resin, to produce incense. Imitations and substitutes The rarity of mastic and the difficulty of its production make it expensive.
