Medical Forum / General / Pharmacy / February 2007uncapped Hydrogen Peroxide burns skin
I used some old Hydrogen Peroxide that had been left uncapped on a cut and it burned like acid and turned the skin exposed by the cut white. Anyone have any idea how the H202 changed chemically to become so caustic? Did it bond with the Nitrogen in the air somehow? > I used some old Hydrogen Peroxide that had been left uncapped on a cut > and it burned like acid and turned the skin exposed by the cut white. > Anyone have any idea how the H202 changed chemically to become so > caustic? Did it bond with the Nitrogen in the air somehow? Hydrogenperoxide does exactly what you describe all by itself. Leaving it uncapped makes it less potent, not more, it will break down to water and oxygen, both of which are not "caustic".

Was the bottle you used the usual 3 percent used for cuts or did you have a 6 percent bottle used for bleaching? > >> > I used some old Hydrogen Peroxide that had been left uncapped on a cut > >> > and it burned like acid and turned the skin exposed by the cut white.

The only thing that is different is that it was old and left uncapped for a couple of months. |
