How is adipocere formed?

Adipocere, “grave wax,” is a waxy or greasy decomposition product formed by hydrolysis and hydrogenation of tissue fats. Once formed, it appears stable for extended periods. Adipocere has generally been considered to result from bacterial action, commonly in warm, damp, anaerobic environments.

In what conditions does adipocere form?

Factors favorable to adipocere formation include mildly alkaline pH, warm temperature, anaerobic conditions, and moisture. Cold temperature, lime, and aerobic conditions are limiting factors. Clearly, many factors other than postmortem interval are involved in adipocere formation.

What is adipocere and what is its forensic relevance?

Also known as “grave wax,” adipocere (from the Latin, adipo for fat and cera for wax) is a grayish-white postmortem (after death) matter caused by fat decomposition, which results from hydrolysis and hydrogenation of the lipids (fatty cells) that compose subcutaneous (under the skin) fat tissues.

What is adipocere used for?

In corpses, the firm cast of adipocere allows some estimation of body shape and facial features, and injuries are often well-preserved.

What is Adipocere and when does it occur in the decomposition process?

Adipocere is also known as grave or corpse wax or the “fat of graveyards”, and is produced when adipose tissue decomposes, usually in cold wet conditions, by the hydrolysis of triglycerides into glycerine and free fatty acids [33].

What is the meaning of Adipocere?

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.

How does a body Saponify?

Saponification is an event that occurs after death in which a body undergoes chemical changes that transform body fat into a substance called adipocere. During the adipocere formation, the water from the soft tissue is extracted, eventually making the body inhospitable to further bacterial decomposition.

How is adipocere helpful to investigators?

The formation of adipocere preserves corpses in a permanent firm cast. In a forensic context, adipocere can preserve injuries and thus help to determine the cause of a person’s death [13, 14] .

What is adipocere and when does it occur in the decomposition process?

What is the meaning of adipocere?

What is adipocere and how can it be used to estimate the postmortem interval?

The adipocere is admixed with the mummified remains of muscles, fibrous tissues and nerves. The presence of any adipocere indicates that the postmortem interval is at least weeks and probably several months. Under ideal warm, damp conditions, adipocere may be apparent to the naked eye after 3–4 weeks.

Does adipocere delay putrefaction?

PATHOLOGY | Postmortem Interval During the early stages of its production a penetrating and very persistent ammoniacal smell is emitted. Adipocere develops as the result of hydrolysis of fat with the release of fatty acids, which, being acidic, then inhibit putrefactive bacteria.
