Hydrogen peroxide occurs naturally in the air as a small amount of gas. Hydrogen peroxide is unstable, easily decomposes into oxygen and water with the release of heat. Although non-flammable, it is a strong oxidizing agent that can cause spontaneous combustion when in contact with organic material. Hydrogen peroxide is available in low concentrations (3-9%) for many home medical applications and as a clothing and hair bleach.
