Liquids/Chemicals which cause mild chemical burns?

[ChildOfMaroon]

I am trying to figure out which chemicals/compounds might cause mild chemical burns in liquid form. I am not necessarily interested in things which would cause severe burns like acid; rather, I am interested in things which would give mild burns to human skin, perhaps after prolonged exposure. I was also interested, primarily, in organic chemicals which arise naturally in nature and not things which are synthesized, but I understand that might not be possible. Any help would be much appreciated. Thanks!

It is acid and OP said: "I am not necessarily interested in things which would cause severe burns like acid".

I don't know what kind of vinegar you are using but I've never had a severe burn from vinegar.

Because it is diluted to ~10%. In ready dish even more diluted.

You also did not have severe burns from hydrochloric acid which is in your stomach.

Apart from bases,

Hydrogen Peroxide perhaps?

https://en.wikipedia.org/wiki/Hydrogen_peroxide#Safety

"In high concentrations, hydrogen peroxide is an aggressive oxidizer and will corrode many materials, including human skin. In the presence of a reducing agent, high concentrations of H₂O₂ will react violently."

Hello COM, and welcome.

ScienceForums is a good place to com ask questions and learn new stuff.

I notice you have asked a second question since this one, but not tarried in this thread.

Other members who put in effort to help you appreciate your further input to what is, after all, your subject.

 

Anyway the word you ned to search with is 'caustic'. (Google etc)
Caustic is a general technical term for substances that can chemically attack tissue, both living and dead.
It somewhere blends into 'corrosive' . Corrosive substance attack tough inert things like metals and rocks etc.

As has already be said, many caustic substances rely on being acid or alkaline; however I note you are particularly interested in 'natural' substances so here is a good resource

Atkin's Molecules

Peter Atkins

Cambridge University Press.

Peter describes lots of molecules importart to us including those that can have a burnsing effect in sufficint concentratin for example the substances in pepper and chilles

Piperine and Capsaicin.

Why?

I can't think of any good reason for this.

And vinegar doesn't "cause severe burns like acid" so...

[swansont]

whether it causes severe burns would depend (at least in part) on the concentration. Something that burns severely at one value may not when diluted.

I, too, would like to know why the OP wishes to know this.
