What is Hydrogen Peroxide?

Hydrogen Peroxide is a very pale blue liquid which appears colorless in solution. It is a weak acid with strong oxidizing properties making it a powerful bleaching agent. Hydrogen Peroxide is a component of living cells, playing a role in host defense and oxidative bio-synthetic reactions. Peroxide also plays an important role in cancer development. Hydrogen Peroxide is unstable, readily decomposing to oxygen and water with a release of heat. It is non-flammable but as a strong oxidizer, it can cause spontaneous combustion when it contacts organic material.

Hydrogen Peroxide Exposure and Health Risks

Hydrogen Peroxide is an irritant; its vapors may irritate the eyes and mucous membranes. Gas may explode if heated under pressure. Hydrogen Peroxide is harmful if swallowed or inhaled. Inhalation can cause respiratory irritation. Direct contact with high concentrations or high exposure of hydrogen peroxide may cause severe dermal burns and eye damage. Hydrogen Peroxide has been verified to be of low concern to the environment.
