Adipocere, also known as corpse wax, grave wax or mortuary wax, is a wax-like organic substance formed by the anaerobic bacterial hydrolysis of fat in tissue, such as body fat in corpses. In its formation, putrefaction is replaced by a permanent firm cast of fatty tissues, internal organs, and the face.

What is corpse wax used for?

Skin fat in buried bodies transforms into an organic substance called adipocere, known also as corpse, grave or mortuary wax. The result is a white, crumbly waxy film that covers the corpse and prevents further decay.

What happens to body fat after death?

Strange, but true: “Bodies left in a cool, damp environment often decompose in a chemical process called adipocere that turns the fat into soap,” Dr. Melinek says.
