What it is. This hydrogen peroxide is a 6% aqueous solution, supplied in a 1-gallon size. It is a clear, colorless oxidizer twice as strong as standard 3% peroxide, used for cleaning, disinfection, bleaching, and reagent applications.
-
What 6% delivers. A 6% solution contains about 60 g of H2O2 per liter (roughly 1.8 M) and is often described as 20 volume, releasing about 20 volumes of oxygen per volume of liquid on complete decomposition (calculated).
-
Why choose 6%. Doubling the strength speeds oxidation and stain removal and increases disinfecting power compared with 3%, while remaining far less hazardous than 30% or 35% concentrates. It is a practical middle strength for routine cleaning and processing.
-
How it works. Hydrogen peroxide releases reactive oxygen species that oxidize organic matter, bleach stains, and inactivate microorganisms, breaking down into water and oxygen with no persistent residue.
-
Stability. Light, heat, metals, alkalinity, and contamination accelerate decomposition. Keep the container closed in a cool, dark place, and never return used solution to stock.
-
Diluting to 3%. Mixing equal volumes of 6% peroxide and deionized water gives about 3% (calculated). That makes the gallon a flexible stock for both full-strength and standard 3% uses.
-
Checking strength. Because peroxide slowly decomposes, confirm strength before critical use by titration with standardized potassium permanganate in acid, or with simple peroxide test strips for routine checks.

-
Handling. Six-percent hydrogen peroxide can irritate or damage eyes and may irritate skin with prolonged contact. Wear safety glasses or goggles and gloves, and rinse splashes with water. For concentrate, see Lab Pro's Hydrogen Peroxide 30 to 32%, 1 Pint.
-
Where it is used. Six-percent hydrogen peroxide is used to clean and disinfect surfaces and equipment, bleach and remove stains, support cosmetic and hair-care formulation work, support aquarium and pond treatment studies, support teaching labs, and serve as a stock for 3% solutions.

Applications / Common Uses
-
Surface disinfection: Cleans and disinfects equipment and benches.
-
Bleaching: Removes stains and whitens materials.

Storage, Handling & Shipping
Store tightly closed in a cool, dark place away from heat and direct sunlight. Hydrogen peroxide slowly decomposes to water and oxygen, and light, heat, and contamination speed that process, so keep the container closed and never return used solution to stock.
-
Incompatible materials: Strong reducing agents, metals and metal salts, and organic contaminants.
-
Personal protection: Safety glasses and gloves.
-
Spill response: Dilute with water and wipe up.
-
First aid: Eyes: rinse with water for several minutes and seek medical advice if irritation persists.
