Caustic poisons - chemical substances or their mixtures that have a local irritant, necrotizing and melting effect when in contact with mucous membranes or skin. After absorption, such poisons also have a general toxic effect. Organic (acetic, carbolic) and inorganic (nitric, sulfuric and hydrochloric) acids, as well as caustic alkalis (caustic soda, caustic potassium, caustic soda) are of the greatest importance for forensic medicine. Poisoning with oxalic acid , formalin , hydrogen peroxide, potassium permaganate, alcoholic solution of iodine, liquid ammonia, etc. are much less common. Their local action is fundamental and is directly dependent on the concentration of the substance. The pain irritation resulting from a chemical burn can cause shock and rapid death. The general toxic, resorptive effect of poison appears during a prolonged course of poisoning.
