Colorless liquid with a slightly sharp odor. [Note: The pure compound is a crystalline solid below 12 degrees F. Often used in an aqueous solution.]; [NIOSH]


Used for the bleaching, disinfecting, and producing other chemicals; H2O2 is used in the textile, wood pulp, food, hairdressing, fur, and water treatment industries; [ACGIH] Used in photography (hypo eliminator); [] Used in the deliming and dyeing stages of leather production; [PMID 21938525]


Liquid causes second degree burns after a few minutes of contact; [CHRIS] Hydrogen peroxide 30-70% is corrosive to the skin. [Quick CPC] "When used for household disinfectant purposes (3% to 5%), it is mildly irritating to the skin and mucous membranes. At a concentration of 10%, which is found in some hair-bleaching solutions, it is strongly irritating and may be corrosive." [ATSDR Medical Management] Corrosive to the skin and eyes and irritating to the respiratory tract; [ICSC] Hydrogen peroxide solutions 35% and greater could cause pulmonary edema after inhalation; [CHEMINFO]

Excerpts from Documentation for IDLHs

Other animal data: It has been reported that mice tolerated a single 4hour exposure to 75 ppm [Svirbely]. Human data: It has been stated that although the shortterm exposure tolerance is unknown, it is probably about 75 ppm [AIHA 1957]. Death has resulted in a man who drank 100 ml [Raukhverger and Solodko 1974].
