Adipocere, also known as grave wax or corpse wax, is a substance that forms on the remains of dead animals and humans. It is a grayish-white, soft and waxy material that is derived from the decomposition of fats in the body. Although the term adipocere is most commonly used, other words can be used to describe this peculiar substance. Some synonyms for adipocere include mortuary wax, sepulchral wax, and corpse butter. The term mortuary wax emphasizes the association of adipocere with funerary practices, while sepulchral wax refers to its formation within tombs or burial sites. Corpse butter is another colloquial term used to describe the greasy, waxy consistency of adipocere.
