Hydrogen Peroxide 35% H2O2
in Oxidisers
$29.00 - $585.00
In stockPrice varies by Size.
Hydrogen peroxide supplied as a 35% aqueous solution – a colourless, odourless liquid with a pH of 2 to 4, relative density 1.12 at 20-25 °C and a boiling point of 106 °C. The SDS classifies it Oxidising Liquid Category 2 (H272) and Skin Corrosion Category 1 (H314), and records the solution itself as non-combustible. Available in 1 quart, 4 x 1 quart, 1 gallon, 5 gallon and 55 gallon.

Description
Hydrogen peroxide, listed as a 35% aqueous solution. Hydrogen peroxide at this strength is an oxidiser, not a cleaning-agent-strength product – it is classified alongside oxidising liquids and skin corrosives, and should be segregated in storage from organics, reducing agents and combustible material.
Physical data (from the SDS)
- Colourless, odourless liquid
- pH 2-4
- Melting point -27 °C
- Boiling point 106 °C
- Relative density 1.12 at 20-25 °C
- Vapour pressure 17.4-25 mmHg
- Viscosity 1.25 mPa.s
- Non-combustible
Classification
Oxidising Liquid Category 2 (H272, may intensify fire); Acute Toxicity Category 4 (H302, harmful if swallowed); Skin Corrosion Category 1 (H314, causes severe skin burns and eye damage); Specific Target Organ Toxicity single exposure Category 3 (H335). The SDS states that untreated corrosion wounds heal slowly and with difficulty, and that eye splashes require immediate hospital referral.
A note on the declared concentration
This item is listed as 35%. The composition section of the manufacturer safety data sheet supplied with it declares a hydrogen peroxide content band of 25-34% w/v. If the exact assay matters for your method, confirm it for the batch you receive rather than relying on the listing figure.
Container sizes
1 quart, 4 x 1 quart, 1 gallon, 5 gallons and 55 gallons.
Frequently asked questions
What concentration is actually supplied?+
The item is listed as 35%. The composition section of the manufacturer SDS supplied with it declares a hydrogen peroxide band of 25-34% w/v. Where the assay is method-critical, confirm it for the batch you receive rather than relying on the listing figure.
What are the physical properties?+
Colourless and odourless, pH 2 to 4, melting point -27 °C, boiling point 106 °C, relative density 1.12 at 20-25 °C, vapour pressure 17.4-25 mmHg and viscosity 1.25 mPa.s. The SDS records the solution as non-combustible in itself.
How is it classified?+
Oxidising Liquid Category 2 (H272), Acute Toxicity Category 4 (H302), Skin Corrosion Category 1 (H314) and STOT single exposure Category 3 (H335).
Why is it in the oxidisers category rather than with cleaning agents?+
Because the SDS classifies it as an Oxidising Liquid Category 2 - H272, may intensify fire. Storage segregation from organics, reducing agents and combustible material follows from that classification, and grouping it with general cleaning products would obscure it.
What does the SDS say about skin and eye contact?+
Skin contact requires immediate rinsing with plenty of water and immediate medical treatment, because untreated corrosion wounds heal slowly and with difficulty. Even small amounts splashed into the eyes require the casualty to be taken immediately to hospital.
What container sizes are available?+
1 quart, 4 x 1 quart, 1 gallon, 5 gallons and 55 gallons.
