Does 99.8% acetic acid cause severe skin burns like formic acid? I've so far handled only concentrated fuming nitric, sulfuric &amp; hydrochloric acids from the inorganic side. Even during an accidental spill on the hand I did say only the $\ce{HNO3}$ affects the skin by turning it yellow and the top layer sometimes peels off.
But in the organic acid side I've had once experience in the past long long ago with formic acid and it was pretty nasty. A really pungent smell and if it gets on the hand then immediately the top layer of skin will peel off. Worse than there inorganic ones. Is 99.8% acetic acid this strong?
I'm about to prepare some homemade stop bath solution for Black and White film development. I'm going to prepare a 10% acetic acid solution. Just wanted to know though I will wear nitrile gloves, in case a few drops come on the skin how bad will it be? I can't seem to find any video or much info of it's effect on YouTube or anywhere either? Just want to take all precautions.
Yes it is corrosive to skin.  The Safety Data Sheet identifies it as Category 1A for skin corrosion, which means:

A substance that, according to animal data acquired from a scientifically validated method, produces irreversible damage to the skin after an exposure of three minutes or less, and within one hour of observation, in at least one of three animals.

Don't let the &quot;organic&quot; part fool you.  In terms of handling hazards glacial acetic acid rivals concentrated hydrochloric acid, and actually beats it in skin corrosion classification.
