First, methanol (whether it enters the body by ingestion, inhalation, or absorption through the skin) can be fatal due to its CNS depressant properties in the same manner as ethanol poisoning. Second, in a process of toxication , it is metabolized to formic acid (which is present as the formate ion) via formaldehyde in a process initiated by ...
Methanol fuel is an alternative biofuel for internal combustion and other engines, either in combination with gasoline or independently. Methanol (CH 3 OH) is less expensive to sustainably produce than ethanol fuel, although it is more toxic than ethanol and has a lower energy density than gasoline.
Unlike ethanol, however, methanol is toxic to humans and is commonly used as a solvent in industrial processes, a precursor for producing formaldehyde and an ingredient in products like antifreeze ...
Toxicity from methanol is related to the dose you get and how your body handles it. As with alcohol, the less you weigh, the more you can be affected by a given amount.
Methanol and its vapours are flammable. Moderately toxic for small animals – Highly toxic to large animals and humans (in high concentrations) – May be fatal/lethal or cause blindness and damage to the liver, kidneys, and heart if swallowed – Toxicity effects from repeated over exposure have an accumulative effect on the central nervous system, especially the optic nerve – Symptoms may ...
1 US gallon or 3.785 litres of denatured alcohol in a metal container. Denatured alcohol, also known as methylated spirits, metho, or meths in Australia, Ireland, New Zealand, South Africa, and the United Kingdom, and as denatured rectified spirit, is ethanol that has additives to make it poisonous, bad-tasting, foul-smelling, or nauseating to discourage its recreational consumption.

In addition to the toxicity of ethanol, the main psychoactive component of alcoholic beverages, other physiological symptoms may arise from the activity of acetaldehyde, a metabolite of alcohol. [11] These effects may not arise until hours after ingestion and may contribute to a condition colloquially known as a hangover.
