Information @ a Glance

General

  • Hydrogen peroxide (H2O2) is a very pale blue liquid which appears colorless in a dilute solution, slightly more viscous than water.
  • Hydrogen peroxide is a weak acid. It has strong oxidizing properties and is therefore a powerful bleaching agent that is mostly used for bleaching  paper.
  • Hydrogen Peroxide found its use as a disinfectant, as an oxidizer, as an antiseptic, and in rocketry as a monopropellant, and in bipropellant systems.
  • The oxidizing capacity of hydrogen peroxide is so strong that the chemical is considered a highly reactive oxygen species.
     

Process

  • Hydrogen peroxide is naturally produced as a byproduct of oxygen metabolism, and virtually all organisms possess enzymes known as peroxidases.
  • Hydrogen peroxide always decomposes exothermically into water and oxygen gas spontaneously.
  • Hydrogen peroxide is a weak acid, and it can form hydroperoxide or peroxide salts or derivatives of many metals.
  • Hydrogen peroxide is manufactured by the autoxidation of 2-ethyl-9,10-dihydroxyanthracene to 2-ethylanthraquinone and hydrogen peroxide using oxygen from the air. This is known as the Riedl-Pfleiderer process.
     

Applications

  • H2O2 can be used either as a monopropellant or as the oxidizer component of a bipropellant rocket.
  • Industrial applications for hydrogen peroxide include the manufacture of sodium percarbonate and sodium perborate, used as mild bleaches in laundry detergents.
  • Hydrogen peroxide can be used as a toothpaste when mixed with correct quantities of baking soda and salt.
  • Hydrogen peroxide and benzoyl peroxide are sometimes used to treat acne.
  • Hydrogen peroxide is used as an emetic in veterinary practice.
     

Report

  • Antioxidant potential of silk protein sericin against hydrogen peroxide-induced oxidative stress in skin fibroblasts.
  • Hydrogen Peroxide Health Risks concerning Teeth Whitening.
  • The Food and Drug Administration (FDA) has not approved hydrogen peroxide for human consumption; therefore, the sale of hydrogen peroxide for this purpose is illegal.
  • Study of wet hydrogen peroxide oxidation process applied for advanced treatment of wastewaters containing high phenol concentrations.
