Decomposed by many organic solvents.

May decompose violently if traces of impurities are present.

Decomposed into water and oxygen by many organic solvents.

Agitation or contact with rough surfaces, metals or many other substances accelerates decomposition. Rapidly decomposed by alkalies, finely divided metals; the presence of mineral acid renders it more stable.

Decomposition continuously occurs even at a slow rate when the compound is inhibited, and thus it must be stored properly and in vented containers. High-strength hydrogen peroxide is a very high-energy material. When it decomposes to oxygen and water, large amounts of heat are liberated, leading to an increased rate of decomposition, since decomposition is accelerated by increases in temperature. This rate increases about 2.2 times per 10 °C temperature increase between 20 and 100 °C.

Spontaneous ignition may occur when contact with combustible materials is made. Oxygen released in decomposition will promote combustion. Fires can be of the flaring type but are not explosive unless confined. Vapor concentration greater than 40 percent by weight can be decomposed explosively at 1 atmosphere pressure. Severe explosion hazard when it is exposed to heat, mechanical impact, detonation of a blasting cap, or caused to decompose catalytically. Decomposition can build up large pressures of oxygen and water which may then burst explosively. Avoid oxidizable materials including iron, copper, brass, bronze, chromium, zinc, lead, manganese, silver, catalytic metals. Avoid mechanical impact, uncovering the container, contact with combustible materials, light, temperatures above 95F, hot wires, catalytic impurities. (EPA, 1998)

A dangerous fire hazard by chemical reaction with flammable materials. Hydrogen peroxide is a powerful oxidizer, particularly in the concentrated state. It is important to keep containers covered because the contents of uncovered containers are much more prone to react with flammable vapors, gases, etc.; and, if uncovered, the water from a hydrogen peroxide solution can evaporate, concentrating the material and thus increasing the fire hazard.

... Solutions of hydrogen peroxide in concentration in excess of 65 wt% heat up spontaneously when decomposed to water + 1/2 oxygen. Thus, 90 wt% soln, when caused to decompose rapidly due to the introduction of a catalytic decomposition agent, can get quite hot and perhaps start fires.

Since the compound is such a strong oxidizer, when spilled on combustible materials it can set fire to them. Detonation can occur if the peroxide is mixed with incompatible (most) organic compounds.

Leakage from drums of 35% hydrogen peroxide onto a wooden pallet caused ignition of the latter when it was moved. Combustion, though limited in area, was fierce and took some time to extinguish. Leakage of 50% peroxide onto supporting pallets under polythene sheeting led to spontaneous ignition and a fierce fire. Contact of 50% peroxide with wood does not usually lead to spontaneous ignition, but hot weather, dry wood and the thermal insulation of the cover may have contributed to ignition.

Hydrogen peroxide is a colorless liquid at room temperature with a bitter taste. Small amounts of gaseous hydrogen peroxide occur naturally in the air. Hydrogen peroxide is unstable, decomposing readily to oxygen and water with release of heat. Although nonflammable, it is a powerful oxidizing agent that can cause spontaneous combustion when it comes in contact with organic material. Hydrogen peroxide is found in many households at low concentrations (3-9%) for medicinal applications and as a clothes and hair bleach. In industry, hydrogen peroxide in higher concentrations is used as a bleach for textiles and paper, as a component of rocket fuels, and for producing foam rubber and organic chemicals.

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]

Excerpt from ERG Guide 143 [Oxidizers (Unstable)]:；Refer to the "General First Aid" section. Specific First Aid: Contaminated clothing may be a fire risk when dry. (ERG, 2024)

EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.；SKIN: IMMEDIATELY flood affected skin with water while removing and isolating all contaminated clothing. Gently wash all affected skin areas thoroughly with soap and water. IMMEDIATELY call a hospital or poison control center even if no symptoms (such as redness or irritation) develop. IMMEDIATELY transport the victim to a hospital for treatment after washing the affected areas.；INHALATION: IMMEDIATELY leave the contaminated area; take deep breaths of fresh air. If symptoms (such as wheezing, coughing, shortness of breath, or burning in the mouth, throat, or chest) develop, call a physician and be prepared to transport the victim to a hospital. Provide proper respiratory protection to rescuers entering an unknown atmosphere. Whenever possible, Self-Contained Breathing Apparatus (SCBA) should be used; if not available, use a level of protection greater than or equal to that advised under Protective Clothing.；INGESTION: DO NOT INDUCE VOMITING. Corrosive chemicals will destroy the membranes of the mouth, throat, and esophagus and, in addition, have a high risk of being aspirated into the victim's lungs during vomiting which increases the medical problems. If the victim is conscious and not convulsing, give 1 or 2 glasses of water to dilute the chemical and IMMEDIATELY call a hospital or poison control center. IMMEDIATELY transport the victim to a hospital. If the victim is convulsing or unconscious, do not give anything by mouth, ensure that the victim's airway is open and lay the victim on his/her side with the head lower than the body. DO NOT INDUCE VOMITING. Transport the victim IMMEDIATELY to a hospital. (NTP, 1992)

To explore the cardiac effects of iron with or without hydrogen peroxide, the isolated perfused rat heart and enzymatically isolated ventricular cardiomyocyte were used. It was shown that treatment with cell-permeable iron (Fe-HQ) for 10 min reduced the contractile amplitude and velocity and end diastolic cell length in the cardiomyocyte and increased the contents of lactate dehydrogenase (LDH) and creatine kinase (CK) in the coronary effluent and malondialdehyde (MDA) in the myocardium. The left ventricular developed pressure (LVDP), +/-dP/dtmax, and heart rate and coronary flow showed a biphasic phase, an increase at first followed by a decline. Treatment with hydrogen peroxide for 10 min following Fe-HQ augmented the effect of iron with an increase in coronary LDH and CK release and myocardial MDA content, and decrease in LVDP, +/-dP/dtmax and heart rate. Perfusion of reduced glutathione with hydrogen peroxide counteracted these effects of Fe-HQ and hydrogen peroxide while dimethyl sulfoxide had no effect on the injury induced by Fe-HQ and hydrogen peroxide in the isolated rat heart. This suggests that augmentation of myocardial injury as a result of an increase in intracellular iron by hydrogen peroxide might involve the dysfunction of sulfydryl group containing proteins but not the hydroxyl radicals.

It has been shown that the mucolytic agent erdosteine (N-carboxymethylthio-acetyl-homocysteine thiolactone) has anti-inflammatory and anti-oxidant properties, and an active metabolite I (MET I) containing pharmacologically active sulphydryl group has been found to have a free radical scavenging activity. The aim of this study was to assess the ability of erdosteine metabolite I to protect A549 human lung adenocarcinoma cell against hydrogen peroxide (H2O2)-mediated oxidative stress and oxidative DNA damage. When A549 cells were pre-treated with the active metabolite I (2.5-5-10 ug/mL) for 10-30 min and then exposed to H2O2 (1-4 mM) for two additional hours at 37 degrees C, 5% at CO2, the intracellular peroxide production, reflected by dichlorofluorescein (DCF) fluorescence, decreased in a concentration-dependent manner. Furthermore, using a comet assay as an indicator for oxidative DNA damage, it was found that the metabolite I prevented damage to cells exposed to short-term H2O2 treatment. The data suggest that this compound is effective in preventing H2O2-induced oxidative stress and DNA damage in A549 cells. The underlying mechanisms involve the scavenging of intracellular reactive oxygen species (ROS).

Oxidative stress reduces cell viability and contributes to disease processes. Flavonoids including anthocyanins and proanthocyanidins reportedly induce intracellular antioxidant defense systems. Thus, in this study, we examined the antioxidant effects of a commercial extract from black soybean seed coats (BE), which are rich in anthocyanin and proanthocyanidin, and investigated the associated intracellular mechanisms in HepG2 cells. HepG2 cells treated with hydrogen peroxide (HPO) showed 60% viability, whereas pretreatment with BE-containing media for 2 hr ameliorated HPO-mediated cell death by up to 90%. Pretreatment with BE for 2 hr partially blocked HPO-mediated activation of extracellular-signal-regulated kinase (ERK) in HepG2 cells, and that for 1 hr led to a 20% increase in intracellular total protein phosphatase (PP) activity, which is known to deactivate protein kinases. These results indicate that BE prevents HPO-mediated cell damage by inhibiting ERK signaling, potentially via PPs.

Hydrogen peroxide (HP) or cyanide (CN) are bacteriostatic at low-millimolar concentrations for growing Escherichia coli, whereas CN+HP mixture is strongly bactericidal. We show that this synergistic toxicity is associated with ... chromosomal fragmentation. Since CN alone does not kill at any concentration, while HP alone kills at 20 mM, CN must potentiate HP poisoning. The CN+HP killing is blocked by iron chelators, suggesting Fenton's reaction. Indeed, we show that CN enhances plasmid DNA relaxation due to Fenton's reaction in vitro. However, mutants with elevated iron or HP pools are not acutely sensitive to HP-alone treatment, suggesting that, in addition, in vivo CN recruits iron from intracellular depots. We found that part of the CN-recruited iron pool is managed by ferritin and Dps: ferritin releases iron on cue from CN, while Dps sequesters it, quelling Fenton's reaction. We propose that disrupting intracellular iron trafficking is a common strategy employed by the immune system to kill microbes.

IDENTIFICATION AND USE: Hydrogen peroxide is a colorless liquid. It is an oxidizing agent which, in the presence of organic matter or if permitted to become alkaline, vigorously decomposes to oxygen and water. Hydrogen peroxide is used as a 6% solution for bleaching hair, and some disinfectant solutions for contact lenses contain a 3% hydrogen peroxide. Chlorine-free bleaches contain 6% hydrogen peroxide. Some newer fabric stain removers and bleaches contain 5% to 15% hydrogen peroxide. Industrial strengths of hydrogen peroxide are manufactured up to 90%. They are used mainly as bleaching and oxidizing agents. Solutions of 90% are used as rocket fuel. HUMAN STUDIES: The dissociation of hydrogen peroxide is a violent and exothermic reaction. Ingestion results in gastrointestinal irritation, the severity of which depends on the concentration of the solution. There is also a risk for a gas embolism. A number of deaths have been reported in the literature. In most cases the exposures were to concentrated solutions of 30% to 40%. Other reactions include vomiting (the vomitus may be frothy due to the liberation of oxygen), hematemesis, burning of the throat, and gastric distension due to the release of oxygen. Lethargy, coma, convulsions, shock and respiratory arrest have also been reported. Gastrointestinal bleeding and burns to the stomach and duodenum may occur. In severe cases ischemic ECG changes and EMD (electromechanical dissociation) may be observed because of embolization of the heart restricting blood flow. Hydrogen peroxide is an irritant to the skin with paraesthesia, blistering and whitening; solutions >10% may cause burns. Hydrogen peroxide is irritating to the eyes with a burning sensation, conjunctival hyperemia, lacrimation, and severe pain which resolves within a few hours. There are rare cases of temporary corneal injury resulting from the application of 3% solution to the eye on contact lenses including punctuate staining of the cornea, decreased visio

Gaseous hydrogen peroxide is a key component and product of the earth's lower atmospheric photochemical reactions, in both clean and polluted atmospheres. Atmospheric hydrogen peroxide is believed to be generated exclusively by gas-phase photochemical reactions. It has been found in rain and surface water, in human and plant tissues, in foods and beverages and in bacteria(1). Hydrogen peroxide occurs in cloud water with higher values generally occurring in the vicinity of lightning activity(2).

Measurements of hydrogen peroxide concentrations in the gas-phase and in cloud water were obtained in the vicinity of the USA Carolinas coast between late Jan and early Mar 1986. Gas phase concentrations, determined by a fluorometric method, were always less than 2.4 ppb and generally less than 1 ppb. Vertical profiles of hydrogen peroxide in the clear air around clouds and storm systems were highly variable. Concentrations of hydrogen peroxide in cloud water ranged from the detection limit of 0.3 uM to 112 uM, with higher values generally occurring in the vicinity of lightning activity. Hydrogen peroxide concentrations in cloud water were well below those calculated to be in Henry's law equilibrium with gas-phase concentrations of hydrogen peroxide in the cloudy air.

/SIGNS AND SYMPTOMS/ Potential symptoms of overexposure are irritation of eyes, nose and throat; corneal ulceration; erythema, vesicles on skin; bleaching of hair.

/SIGNS AND SYMPTOMS/ Pure hydrogen peroxide, its solutions, vapors, and mists are very irritating to body tissue. This irritation can vary from mild to severe depending upon the concentration of hydrogen peroxide. For instance, solutions of hydrogen peroxide of 35 wt% and over can easily cause blistering of the skin. ... The eyes are particularly sensitive to this material.

/SIGNS AND SYMPTOMS/ Large doses presumably produce gastritis and esophagitis. Cases of rupture of the colon, proctitis and ulcerative colitis have been reported following hydrogen peroxide enemas.

/SIGNS AND SYMPTOMS/ Workers exposed to vapors from 90% hydrogen peroxide have noted primarily respiratory irritation, but splash of such high concentration is generally feared as a potential cause of severe corneal damage.

Hydrogen peroxide exhibits antimicrobial properties against most forms of microorganisms, including dormant forms with known high resistance profiles, such as bacterial spores and protozoal cysts. It acts as an oxidative biocide to generate free radical species to induce DNA, protein and membrane lipid damage via oxidation.

The production of free hydroxyl radicals in the Fenton reaction is thought to be the basis of biocidal actions of hydrogen peroxide. Free radicals eventually lead to oxidative damage proteins and membrane lipids _in vivo_. The oxidizing radical as the ferryl radical induces DNA oxidation.

Hydrogen peroxide topical solution is a weak antibacterial agent, a wound cleanser, and a deodorant. The pharmacologic activity of the drug depends on the release of nascent oxygen which has a powerful oxidizing effect that destroys some microorganisms and chemically alters many organic substances. When hydrogen peroxide topical solution comes in contact with tissues that contain the enzyme catalase, the solution releases oxygen which exerts antibacterial action; the mechanical effect of effervescence loosens tissue debris and pus. The release of nascent oxygen and effervescence is more rapid on wounds, denuded areas, and mucous membranes than on unbroken skin. The presence of reactive organic material such as pus and blood diminishes the efficiency of hydrogen peroxide. The antibacterial activity of hydrogen peroxide is relatively weak and slow and the drug exhibits poor tissue and wound penetration. Hydrogen peroxide's mechanical effect of effervescence and resultant removal of tissue debris is probably a more effective means of reducing the bacterial content of wounds, denuded areas, and mucous membranes than actual antibacterial activity. The drug also appears to have a styptic effect when applied topically to minor wounds. Concentrated solutions of hydrogen peroxide have a bleaching effect on hair and may injure tissue.

Increases in the levels of reactive oxygen species (ROS) are correlated with a decrease in calcineurin (CN) activity under oxidative or neuropathological conditions. However, the molecular mechanism underlying this ROS-mediated CN inactivation remains unclear. Here, we describe a mechanism for the inactivation of CN by hydrogen peroxide. The treatment of mouse primary cortical neuron cells with Abeta(1-42) peptide and hydrogen peroxide triggered the proteolytic cleavage of CN and decreased its enzymatic activity. In addition, hydrogen peroxide was found to cleave CN in different types of cells. Calcium influx was not involved in CN inactivation during hydrogen peroxide-mediated cleavage, but CN cleavage was partially blocked by chloroquine, indicating that an unidentified lysosomal protease is probably involved in its hydrogen peroxide-mediated cleavage. Treatment with hydrogen peroxide triggered CN cleavage at a specific sequence within its catalytic domain, and the cleaved form of CN had no enzymatic ability to dephosphorylate nuclear factor in activated T cells. Thus, our findings suggest a molecular mechanism by which hydrogen peroxide inactivates CN by proteolysis in ROS-related diseases.

Matrix metalloproteinase-2 (MMP-2) is well known to proteolyse both extracellular and intracellular proteins. Reactive oxygen species activate MMP-2 at both transcriptional and post-translational levels, thus MMP-2 activation is considered an early event in oxidative stress injury. Although hydrogen peroxide is widely used to trigger oxidative stress-induced cell death, the type of cell death (apoptosis vs. necrosis) in cardiomyocytes is still controversial depending on the concentration used and the exposure time. We ... investigated the mode of cell death in neonatal rat cardiomyocytes induced by different concentrations (50-500 uM) of hydrogen peroxide at various time intervals after exposure and determined whether MMP-2 is implicated in hydrogen peroxide-induced cardiomyocyte death. Treating cardiomyocytes with hydrogen peroxide led to elevated MMP-2 level/activity with maximal effects seen at 200 uM. Hydrogen peroxide caused necrotic cell death by disrupting the plasmalemma as evidenced by the release of lactate dehydrogenase in a concentration- and time-dependent manner as well as the necrotic cleavage of PARP-1. The absence of both caspase-3 cleavage/activation and apoptotic cleavage of PARP-1 illustrated the weak contribution of apoptosis. Pre-treatment with selective MMP inhibitors did not protect against hydrogen peroxide-induced necrosis. In conclusion hydrogen peroxide increases MMP-2 level/activity in cardiomyocytes and induces necrotic cell death, however, the later effect is MMP-2 independent.

In the AO /Antraquinone/ process, 2-alkyl-9,10-anthraquinones react with hydrogen in the presence of a catalyst to form the corresponding hydroquinones. After the catalyst is removed (otherwise, the hydrogen peroxide would decompose), the hydroquinones are oxidized to quinones with oxygen (usually air) with simultaneous quantitative formation of hydrogen peroxide. Hydrogen peroxide is extracted with water, and the quinones are returned to the hydrogenator to complete the loop. The AO process, therefore, leads to the net formation of hydrogen peroxide from gaseous hydrogen and oxygen.
