The peroxide and vinegar that people will have on hand will make such a dilute concentration of Parecetic acid, that it's effectively harmless.
You have to go really out of the way to get anything above 6% peroxide and 10% acetic acid
Freeze the peroxide, boil the vinegar. Household chemical accidents with more involved steps.
The peroxide is the hard one.
I mean… Walgreens carries 40 Vol hair bleach. Typically that’s %12 peroxide. You can usually get industrial sizes locally too if you live in a larger city, people use it for retro-brighting.
Hrmmmm.... Neat!
Not sure about that.
35% Food Grade Hydrogen Peroxide
Acetic Acid Glacial 99% 2 Gallons (8 Quarts)
Anything that requires you to source chemicals online from specialty suppliers is going really out of the way.
Why would you want to do this though?
If your grocery store has a section for natural cleaners, no dyes, scents etc there will often be cleaning vinegar that is higher concentrations. It's really not that hard to find and most people won't have to go out of their way to get it.
Cleaning vinegar is typically 10%. The regular stuff is 5%
But the extra strength one I often see is 20
You can get 20 at Loews
All the peroxide I ever bought has always been 12%. But I'm from Germany, might be a regional thing
Yeah regional thing for sure, but you can still get up to 20% in the states but it'll be labelled VERY differently from the standard 3-6% stuff that's used for wound care or oral rinses.
So if I go to Germany I can more easily make paracetic acid. Got it.
aww I wanted to melt stuff :(
