Eschar

Eschar is dead tissue that falls off (sheds) from healthy skin. It is caused by a burn or cauterization (destroying tissue with heat or cold, or another method).

An escharotic is a substance (such as acids, alkalis, carbon dioxide, or metallic salts) that causes the tissue to die and fall off.
