BMJ Case Reports · 2012 · observational · n=1

Case report of a caustic chemical skin burn caused by accidental contact with sodium hydroxide, illustrating the corrosive, alkali-injury potential of sodium hydroxide on human skin.

International Journal of Burns and Trauma · 2025 · animal

In rats, sodium hydroxide skin contact caused second-degree (90 s) to third-degree (180 s) burns via lipid saponification and triggered ferroptosis: increased reactive oxygen species, ferrous iron, malondialdehyde and ACSL4/LPCAT3 expression with depleted GPX4 and glutathione, linking NaOH burn injury to disrupted lipid metabolism.
