70% ISO or Regular 70% ?
    #26494383 - 02/20/20 03:49 AM (3 years, 11 months ago)

Hi friends,

this is the second time i post this, the first post some how got deleted. any way i want to know why it is necessary to use 70% ISO.
Because a friend of mine got a distill and he can make regular 92% alcohol. so if he reduces the 92% to 70% can that alcohol be used?
or has it to be ISO Alcohol ?

Thanks for the information guys

70% is more effective for sanitizing as it penetrates cell walls easier than 90%+

As far as the type, it doesn't matter much. Ethanol is a bit more flammable, and is a bit better than isopropyl for sanitizing. But only a bit.

Ethanol has a lower latent heat of vaporisation so isn't as good at drying (at 70%) anyway. 70% Ethanol would leave water behind for significantly longer.

You might have to use a different concentration of ethanolto achieve the same effect. I have no idea how to calculate that though.

thanks for the information, about that the type of alcohol does not matter.
thats what i needed to know, as for 70% or 90% ¨so if he reduces the 92% to 70% ¨ yeah i have read many times that 70% is better because of the cell walls and because 90% evaporated quicker.


Thank you for the information

Thanks for you information, this is really helpful information.
i will register at a university-degree chemistry forum.
and post this question.

thanks

Isn't that a good thing, though? You want whatever you're sanitizing to remain hydrated, so the alcohol can do its job. If it evaporates too quickly it won't sanitize as well.

Not 100% sure, but i think ethanol of a certain concentration will leave water behind rather than helping it evaporate like with IPA. Pretty sure there's a good reason IPA is used for this sort of thing rather than ethanol, just not sure what it is!

Higher concentration iso evaps quicker and has less time to sanitize that’s why people recommend 70.

Not sure about ethanol.......

For iso and ethanol

70% kills better
It has the right osmotic pressure and tonicity to penetrate cells and denature their insides. It may denature surface proteins on cell walls and bacterial envelopes but not to the extent higher percentage alcohol(both iso and ethanol) will. Alcohol is able to permeate cells and then go to work on intracellular components

That's only a minor secondary benefit of the fact that 70% actually kills better.

Thanks Bod for clarifying.......I just went looking for where I read this long ago.

It was your agar tek

did you know
70% alcohol sanitizes better than 90+ or higher concentrations

I use the heads off my still and mix it with my iso. Idk what concentration I'm getting and of what but it's seems to work just. Maybe the last year I've been using it.

There are a couple reasons. Iso is cheaper and widely available. Ethanol that hasn't been denatured is subject to liquor tax and the laws surrounding its production, distribution, and sale. Ethanol is usually denatured with methanol which is more toxic and noxious than either of the other two alcohols.

I've made up to 88% ethanol before, but the effort and time made it too precious to go spraying on tabletops. It was much more fun to drink it with friends who thought they were gonna die after swallowing it. :grin:
