What is Hydrogen Peroxide?
Hydrogen Peroxide (H₂O₂) is a clear, colorless liquid compound composed of hydrogen and oxygen. It is a powerful oxidizing agent with antimicrobial and bleaching properties, commonly used in cleaning, disinfection, and chemical processes.
Chemical Properties of 35% Hydrogen Peroxide Solution
Molecular Structure:

- Molecular Weight: 34.0147 g/mol.
- Solutions contain 35% H₂O₂ by weight and 65% water.
Bonding:
- Contains a peroxide bond (O-O) that is relatively weak, making it reactive.
- Hydrogen bonding in solutions contributes to increased viscosity and stability.
pH:
- The 35% solution is weakly acidic, with a pH of approximately 3.5–4.0.
Decomposition:
- Decomposes into water (H₂O) and oxygen (O₂), releasing heat (exothermic reaction): 2H2O2→2H2O+O22H₂O₂ → 2H₂O + O₂2H2O2→2H2O+O2
- Decomposition is accelerated by heat, light, or contaminants such as metals and alkalis.
Oxidation and Reduction:

Guide to Properly Storing 35% Hydrogen Peroxide

- Use an appropriate storage container: Store 35% hydrogen peroxide in a dark, opaque container made from non-reactive materials like HDPE or glass to shield it from light and maintain its potency.
- Apply clear labeling: Mark the container with the contents, concentration, and necessary safety warnings to ensure correct identification and prevent accidents.
- Store in a suitable environment: Keep the container in a cool, dark place, away from direct sunlight and heat sources for optimal stability and safety.
- Keep away from flammable items: Due to its strong oxidizing capabilities, store hydrogen peroxide separately from flammable materials to reduce the risk of combustion.
- Position the container correctly: Always store the hydrogen peroxide container in an upright position to avoid leaks and spills.
- Inspect the container frequently: Regularly examine the container for any signs of damage, leaks, or cracks, and safely transfer the hydrogen peroxide to a new container if necessary.

35% Hydrogen Peroxide: Safety Measures and Tips

Always wear gloves
When handling 35% food grade hydrogen peroxide, it is crucial to wear gloves, as the concentrated solution can cause skin irritation or burns. Use gloves made of materials that are resistant to peroxide, like nitrile or butyl rubber, for optimal protection.Wear safety goggles
To protect your eyes from accidental splashes or exposure, always wear safety goggles when working with concentrated hydrogen peroxide. Eye injuries from hydrogen peroxide can be severe, so it’s essential to take precautions.Use in a well-ventilated area
Ensure that you are working in a well-ventilated area when handling or using hydrogen peroxide. Adequate ventilation helps to prevent the buildup of potentially harmful vapors that may cause respiratory irritation or discomfort.Store in a cool, dark place
Store 35% food grade hydrogen peroxide in a cool, dark place, away from direct sunlight, heat sources, and flammable materials. Exposure to heat or light can cause the hydrogen peroxide to degrade or react, which may result in the release of oxygen gas and increased pressure inside the container.Keep away from children and pets
Ensure that hydrogen peroxide is stored out of reach of children and pets. The concentrated solution can be dangerous if ingested or if it comes into contact with skin or eyes.Reviews and Experiences Shared by Our Clients
Horrible experience
I bought this peroxide with the peroxide strips to shock my well. I followed all instructions on the strips to test the water from my tap after adding the peroxide to my well. The strips never worked!!!!! I called the company….. no answer so I left a detailed message. I also sent a text message which is recommended to communicate with them. No reply for days!!!! Now I’ve got all this peroxide in my well and I have no idea the ppm. I ended up running my well out and my process to shock my well didn’t work since you have to have a certain ppm sit in your well for 24 hours. Total waste of time, money and water!!! When I finally heard back they said I used the strips incorrectly. They won’t refund so I have to dispute. What a horrible experience!!!

Great stuff
Every 2 years I buy a large order of 35% h2o2 from Bulk Peroxide. It’s a great product for so many things. I do my own dilutions for different strengths. I finally got my MIL and SIL on board with them this past year. I’ve been buying from them for a very long time and I highly recommend them.
Love H2O2!
I love this product! It’s so versatile for use army house. I especially like how it cleans!! I like that I can dilute it to let my kids clean their bathroom safely while not worrying about harsh chemicals like bleach. I appreciate that it’s good grade and I can use it for medicinal purposes too!
Great product, great price!
Bought to treat water in my cold plunge. The shipping was efficient, packaging secure, & product was as described. I’m very pleased & satisfied with the quality & price point. I will definitely re-order!
Fast Delivery
Great service, fast delivery, product just as described, will purchase again and again. Continued success!
Use it daily
I use it in cleaning veggies, fruits and as a household cleaner. Naturally you don’t use it full strength on hardly anything most especially food products. I ordered it through the website and it was delivered in 7-10 days, comes well packaged and arrives without any packaging damage. And I’m happy with the customer service, they are always friendly and expedient! Thank you “Bulk Peroxide” folks!👍�👍�👍�
SOLID COMPANY
TOP NOTCH PRODUCT. GOOD CUSTOMER SERVICE. SHIPPING WAS QUICK AND EFFORTLESS. WELL MANAGED COMPANY.
Good stuff
Really good stuff. Fast hassle free delivery. Good price.
Great product and customer service.
I’ve been a long-term buyer of another company’s H2O2 products, but am happy with this company and their product so will continue to buy from them.
Great Service As Promised
I received it in durable containers in a timely fashion. I transferred 2 of the 4 bottles to the container I typically use in the fridge and put the other 2 in the freezer.
