Fernando, it was not the heat of hydration that damaged your fingernails and cuticles when you were exposed to oxalic and glycerol.


Acids cause tissue damage (as do bases) because they interfere with protein function or destroy proteins outright.

Glycerol facilitates the permeability of the skin, thus will accelerate the movement of the acid through it.  Because the skin around your nail beds is thinner, the underlying tissues there suffered more damage than was done to the rest of your hands, which are covered with a thicker skin.


Had you continued your exposure your entire hands would have been raw and sore.


Remember that the skin surface itself is dead. Damage to underlying live tissues happens when the skin's protective dead layer is removed or dissolved, as probably happened in your case.
