factice

noun

1. (countable, uncountable)Vulcanized unsaturated vegetable or animal oil, used as a processing aid and property modifier in rubber.

   “Although factice is, strictly speaking, not a plasticizer, being added to mixes for a whole range of reasons including the improvement of dimensional stability and rigidity of unsupported articles in hot air cures, the improvement of surface finish and electrical insulation, it does nevertheless act as a softener, improving filler dispersion and decreasing the energy requirements of mixing.”

2. (countable, uncountable)An oversized, mock perfume bottle, usually filled with colored water instead of perfume, used for display purposes in perfumeries.
