35% is not necessisarily the Real Thing, it is a moderately high
dillution. however, it does have dangers associated with it:

Oxidizer. Contact with combustibles may cause fire. Decomposes yielding
oxygen that supports combustion of organic matters and can cause
overpressure if confined.

Corrosive to eyes, nose, throat and lungs. May cause irreversible tissue
damage to the eyes including blindness. May cause skin irritation.

Wear cup type chemical safety goggles and/or full face shield, polyester
or acrylic full cover clothing and rubber or neoprene gloves and shoes.
Avoid cotton, wool and leather. Avoid excessive heat and contamination.
Contamination may cause decomposition and generation of oxygen gas which
could result in high pressures and possible container rupture. Hydrogen
peroxide should be stored only in vented containers and should be
transferred only in a prescribed manner (see FMC technical bulletins).
Never return unused hydrogen peroxide to original container. Empty drums
should be triple rinsed with water before discarding. Utensils used for
handling hydrogen peroxide should be made only of glassy stainless steel,
aluminum or plastic.

Higher consentrations are difficult to locate. Incidentally, the chemical
is used to purify water, and is sold under a variety of trade names.
