Isopropyl alcohol is oxidized to form acetone by alcohol dehydrogenase in the liver [35] and has a biological half-life in humans between 2.5 and 8.0 hours. [35] Unlike methanol or ethylene glycol poisoning, the metabolites of isopropyl alcohol are considerably less toxic, and treatment is largely supportive.
All rubbing alcohols are unsafe for human consumption: isopropyl rubbing alcohols do not contain the ethyl alcohol of alcoholic beverages; ethyl rubbing alcohols are based on denatured alcohol, which is a combination of ethyl alcohol and one or more bitter poisons that make the substance toxic.
Methanol has a moderate to high toxicity in humans. As little as 10 mL of pure methanol when drunk is metabolized into formic acid , which can cause permanent blindness by destruction of the optic nerve . 15 mL is potentially fatal, [ 1 ] although the median lethal dose is typically 100 mL (3.4 fl oz) (i.e. 1–2 mL/kg body weight of pure ...
Highly Toxic: a gas that has a LC 50 in air of 200 ppm or less. [2] NFPA 704: Materials that, under emergency conditions, can cause serious or permanent injury are given a Health Hazard rating of 3. Their acute inhalation toxicity corresponds to those vapors or gases having LC 50 values greater than 1,000 ppm but less than or equal to 3,000 ppm ...
Isopropyl alcohol is an easy to find and use killing agent for amateurs. Potassium cyanide or other cyanide compounds, including calcium cyanide, are also used, but only by experts due to its extreme toxicity. It also has the disadvantages that it makes the specimens brittle when left in the jar for several hours and that it may also cause some ...
Alcohol inhalation is a method of administering alcohol directly into the respiratory system, with aid of a vaporizing or nebulizing device or bag. It is chiefly applied for recreational use, when it is also referred to as alcohol smoking, but it has medical applications for testing on laboratory rats, and treatment of pulmonary edema and viral pneumonia.
Alcohol has been produced and consumed by humans for its psychoactive effects since c. 7000–6600 BC. [21] Alcohol is the second most consumed psychoactive drug globally, behind caffeine. [22] [23] Drinking alcohol is generally socially acceptable and is legal in most countries, unlike with many other recreational substances.
