methanol vs ethanol vs isopropyl alcohol
I don’t think rubbing methabnol on you is harmful, but check anyway. Intermittent small exposure, like the OP describes, has never caused anyone I have ever known any medical problems. I also wouldn’t bathe in any of them. The common names for methyl alcohol—methanol—and isopropyl alcohol—isopropanol—follow the same rules. Ethyl Alcohol vs Isopropyl Alcohol. I’d stay away from methanol.
It’s got three carbons. Manufacturers add it to ethanol to create denatured alcohol, undrinkable by design, for use as a fuel or cleanser. Here’s the Material Safety Data Sheet (MSDS) for methanol. LD50’s only apply if you are drinking it. Interestingly the LD50 values for methanol (5.8 g/kg), ethanol (7.1 g/kg) and isopropanol ((5.8 g/ kg) (i.e the amount that will kill half of the test animals) are very similar. IANAD, but I handle methanol, ethanol, and isopropyl alcohol and there is no reason why it would hurt to use methanol over the others. The bottle is empty but I have a big jug of methyl hydrate in the basement. However, methanol is classed as toxic and do not use on the body! Ingesting even a tiny amount of methanol can cause permanent blindness or death, according to NIH Medline. Intoxication with ethylene glycol (EG), methanol, and isopropyl alcohol is associated with significant morbidity and mortality if left untreated. I wouldn’t drink either one. Ethanol Vs. Methanol. I would recommend against taking any of them internally. IIRC, methanol can be absorbed directly through the skin. Isopropanol still isn’t good for you, but it’s less volatile (less inhalation danger) and won’t make you blind (I think). “Methyl hydrate” (I swear I’ve never heard it called that, but Googling confirms it’s a synonym) is methanol or methyl alcohol, with one carbon. Ethanol is an organic molecule and isopropyl is only a part of organic molecule. Rubbing alcohol is isopropyl diluted with water. The question of ethyl alcohol vs. isopropyl alcohol (IPA) for cleaning electronics has several ramifications for the laboratory supply chain as well as the longevity of laboratory hardware. I suspect that methanol has more low level toxicity (i.e harmful effects). Ethanol is miscible with water, and also it serves as a good solvent. Absorbtion through the skin can occur, although this isn’t as fast as drinking it or breathing the fumes. Methanol (or methyl alcohol) should not be used as a hand sanitizer, hand rub, or surface cleaner to kill the virus that causes the COVID-19 ("coronavirus") disease. Isopropyl vs Ethanol. Although I will buy isopropynol on shopping day I think it’s safe to dab my zit with a little methanol. Other than a beverage ethanol can be used as an antiseptic to clean surfaces from microorganisms, and it is mainly used as a fuel and a fuel additive in vehicles. Ethyl alcohol consists of 2 carbon atoms while isopropyl alcohol has 3 carbon atoms. Isopropyl alcohol has greater lipophilic properties than ethyl alcohol and is less active against hydrophilic viruses (e.g., poliovirus) . I don’t think the OP is taking it internally or using it in culinary applications. Methanol and ethanol are variants of alcohol, and they have different properties and uses. You cannot drink this stuff without getting sick, and it will not get you drunk.. Whats more effective against lipophilic viruses, isopropyl alcohol or ethanol?
Methanol is harder on fingernail polish than isopropyl alcohol. Completely different compounds. IANAD, but I handle methanol, ethanol, and isopropyl alcohol and there is no reason why it would hurt to use methanol over the others.
Ethyl vs. Isopropyl Alcohol. Origin of 'Ethanol' Ethyl alcohol got the name "ethanol" in 1892 as a combination of the word "ethane"—the name of the carbon chain—and the "-ol" ending for an alcohol. Mistaking the two can have potentially very harmful consequences. Concentrated isopropyl alcohol can be separated into a visible layer by adding salt to water.
