Why it is chosen
Peroxide decomposes to water and oxygen. There is no chloride, no sulfate, and no persistent residue to deal with downstream — which is frequently the deciding factor where discharge limits are tight.
Handling
It decomposes on contact with metals, dirt, and organic material, and that decomposition is exothermic and generates oxygen. In a sealed container that means pressure. Vented closures are required, and a peroxide container must never be sealed tight or returned to a drum after removal.
Store in vented HDPE or passivated aluminium, away from heat and combustibles. Never return unused product to the original container — contamination that would be harmless in most chemicals starts a runaway decomposition here.
At 35% it causes severe eye damage and skin burns that whiten the skin on contact. Rinse immediately and at length.
Documents
Safety data sheets and certificates are available to account holders. Request one below and we send it the same business day — or ask us to attach documents to every shipment automatically so you are not requesting them one at a time.
Read the sheet before the first use
Section 2 covers the hazards, Section 8 the protective equipment actually required, and Section 10 what this must not be stored next to. Storage incompatibility is the single most common cause of serious chemical incidents. How to read an SDS
