I was buying and studying the label on a bottle of alcohol spray and a bottle of liquid alcohol. Their ingredients were Ethanol(Alcohol) 75% and isopropyl alcohol(75%) respectively. Is there any difference?
One uses isopropylic alcohol for disinfectant gels (like the ones we use now with the pesky virus around), in order to prevent idiots from drinking it. The „technical name” for it is „denaturated alcohol”.kenny1999 said:I was buying and studying the label on a bottle of alcohol spray and a bottle of liquid alcohol.

I don't believe that is correct.dextercioby said:One uses isopropylic alcohol for disinfectant gels (like the ones we use now with the pesky virus around), in order to prevent idiots from drinking it. The „technical name” for it is „denaturated alcohol”.
It is denatured to avoid consumption by humans. Often methanol is used because it is cheap and the taxman didn't really care about your health.tech99 said:Methanol is extremely toxic and I don't think it is added to these products.
Ethanol, C2H5OH is a lighter molecule, than propanol C3H7OH. The lighter molecule is more volatile. Ethanol is less toxic to mammals than propanol. I presume both mixtures are 'denatured' as dextercioby mentioned.kenny1999 said:Ethanol(Alcohol) 75% and isopropyl alcohol(75%)
What does "fortified with method" mean here? Isn't a fortified wine simply one that has had wine distillate added to it? Is that what you mean?rayj said:Some countries allow alcoholic drinks to be fortified with method - living on the edge.
Are you sure? Methanol is far too toxic. Can you cite a source for this?rayj said:sysprog,
Thank you. Yes, you are correct. And I meant to spell methanol, not method.
Traditionally, wine is fortified with other distillates. The US only allows wines to be fortified with distillates of fruits. But other countries allow some amount of methanol to be added (it is cheaper) - but may have harsh side-effects.
Both ethanol and isopropyl alcohol are types of alcohol that have a concentration of 75%, meaning that 75% of the solution is made up of alcohol and the remaining 25% is water. The main difference between the two is the type of alcohol molecule they contain. Ethanol, also known as ethyl alcohol, has a two-carbon chain, while isopropyl alcohol has a three-carbon chain. This difference in molecular structure can affect their properties and uses.
Both ethanol and isopropyl alcohol are effective at killing germs and bacteria. They work by denaturing the proteins and dissolving the lipid membranes of these microorganisms, leading to their destruction. The effectiveness of the alcohol depends on the concentration and the contact time with the germs. Generally, a higher concentration of alcohol (above 60%) and a longer contact time (at least 30 seconds) is needed for maximum effectiveness.
Yes, both ethanol and isopropyl alcohol can be used for disinfection purposes. They are commonly found in hand sanitizers, disinfectant wipes, and other cleaning products. However, it is important to check the concentration of alcohol in the product, as well as the contact time needed for effective disinfection.
Both ethanol and isopropyl alcohol are flammable and should be handled with caution. They should be kept away from open flames and heat sources. In addition, prolonged exposure to these alcohols can cause skin irritation and dryness, so it is important to use them in a well-ventilated area and to wash your hands after use.
In most cases, ethanol and isopropyl alcohol can be used interchangeably for disinfection purposes. However, there are some differences in their properties that may make one more suitable for certain applications. For example, ethanol evaporates more quickly than isopropyl alcohol, making it a better choice for cleaning electronics. It is always best to follow the instructions on the product label and use the recommended type of alcohol for a specific task.
