adipocere

noun ad·i·po·cere \ ˈa-də-pə-ˌsir \

Definition of adipocere

: a waxy substance consisting chiefly of fatty acids and calcium soaps that is formed during decomposition of dead body fat in moist or wet anaerobic conditions

Origin and Etymology of adipocere

borrowed from French adipocire, from adipo- adipo- + cire "wax," going back to Old French, going back to Latin cēra — more at cerumen
Note: The e introduced into the English word is presumably after Latin cēra. Word introduced by the French physician and chemist Antoine François de Fourcroy in Annales de Chimie, tome 8 (Jan., 1791), p. 67-70: "Ces dernières propriétés, ainsi que sa qualité sonore, cassante & son tissu souvent grenu, la rapprochent de la cire. On pourroit donc la désigner par le nom de matière adipo-cireuse…La seule substance analogue à cette adipo-cire que l'aie trouvée dans le corps humain, c'est la concrétion blanche & cristalline qui constitue les calculs feuilletés de la vésicule du fiel." ("These latter properties, as well as its sound, brittle quality and its frequent graininess make it similar to wax. One could hence designate it by the term 'adipocerous matter'…The only substance comparable to this adipocere that I have found in the human body is the white, crystalline concretion constituted by the foliated stones in the bile duct….")
