Hydrogen peroxide, aqueous solution, stabilized, with more than 60% hydrogen peroxide appears as a colorless liquid. Vapors may irritate the eyes and mucous membranes. Under prolonged exposure to fire or heat containers may violently rupture due to decomposition. Used to bleach textiles and wood pulp, in chemical manufacturing and food processing.

Noncombustible Liquid, but a powerful oxidizer.
It is not considered to be an explosive; however, when mixed with organic chemicals, hazardous impact-sensitive compounds may result. Materials with metal catalysts can cause explosive decomposition.

Store in an area without drain or sewer access. Separated from food and feedstuffs. See Chemical Dangers. Cool. Keep in the dark. Store in vented containers. Store only if stabilized.
Slightly unstable - will very slowly decompose. Decomposition is promoted by catalysts and heating, so store cool. Light sensitive, keep in the dark. May contain stabilizer. Reacts with rust, brass, zinc, nickel, finely powdered metals, copper and iron and their alloys.
