DIYChemicals 34% Hydrogen Peroxide INDUSTRIAL GRADE
Also known as 34% H2O2, H2O2, or Liquid Oxygen, is a commodity chemical that has a variety of hobbyist and industry uses across the United States. If you are looking to buy high grade 34% Hydrogen Peroxide, you have come to the right place. You will receive a pure, affordable packaged product – without compromising on quality. 34% Hydrogen Peroxide is often imitated with low quality, second-rate suppliers. With our concentrate hydrogen peroxide, DIYChemicals is not a middleman or distributor, we are the supplier.
Features
- Multiple packaged sizes ranging from 1 Quart to 55 Gallons. If you buy large quantities, visit our partners at BulkChemistry.com.
- Used in various chemical, industrial, hydroponics, manufacturing, and cleaning (powdery mildew) applications.
- Satisfaction guaranteed, made in the USA; packaged in Texas!
Uses
With no additives or fillers, you can use 34% Hydrogen Peroxide in almost every industry. Extremely concentrated: dilute to a more manageable concentration first, like 3%. The benefit of buying 34% H2O2 versus 3% H2O2 is that you don’t pay for water-weight. Why would you pay $50+ for mostly water? Instead, 1 gallon of 34% H2O2 can be diluted to the equivalent of 11 gallons of 3% peroxide! Other common usages include cleaning, brightening agent for laundry, and as “liquid oxygen” in horticulture. NOT FOOD GRADE. NEVER INGEST OR APPLY TO BODY. USE SAFETY PROTECTION.
So, it is imperative to remember no matter your intended usage – you could do everything correctly in theory but still have a bad finished product or result if you use low quality starting components. It is important to purchase pure, quality, raw materials. We also stock most of the Chemboys™ products in our store if you are a horticulture or gardening enthusiast! For example, Humic liquid, is a “must-have” for growing!

You website checkout is terrible and needs to be made user friendly. But you did correct it and I finally got my order. The state address system wants to put a few states no matter what. You could have answered my call as I was about to cancel my charge when I received the order.
Bruce Denton (verified owner) –
It took a few weeks to receive my order. Purchased 1 gallon 34% h2o2. What I received was 2 quarts and one burst open in the box during shipping and the ups center actually taped the wet broken box back up.
I called their phone number, left a message and left an email because I ordered a gallon and 2 quarts are only half a gallon. Never heard back from them and am calling my bank by tomorrow to have the transaction reported and reversed if I don’t get a call back or email back from diy chemicals today. It’s been several days already. No email response back and no phone call back.

Julia (verified owner) –
I haven’t actually used my hydrogen peroxide yet, but I wanted to let you all know that when it shipped, the seal must have broken on the bottle because the package was wet. I should have worn gloves when handling, but I didn’t realize the box was saturated with the peroxide and it burned my hands. I washed for about 20 minutes with dish soap and it seemed to go away. Additionally, due to the peroxide solution getting on the outside of the bottle, the letters on the label wiped off as I dried the bottle with a towel. This makes me a little nervous as I can no longer read most of the label. I wanted to let you all know to hopefully prevent this from happening to someone else. Thank you.

NOT FOOD GRADE
I googled food grade Peroxide and did not read this description well enough. I can still use for cleaning, but will not purchase again because I prefer to use food grade peroxide.

This product arrived at my house quickly and worked exactly like I needed it to! I’m doing the Elephant Toothpaste lab with my chemistry students and this higher-strength peroxide is sure to provide a fun day of learning for all of them. I’d highly recommend this product and this website as a whole.

I think the H2O2 got too hot inn transit-all 4 bottles were bowed out at the bottom, and one released some within the plastic bag that unfortunately burned a lot of one hand before I realized there was enough to do that…

It would be best if you shipped in a sealed plastic bag. My bottle leaked during shipping and my hands were bleached white In splotches where the hydrogen peroxide had leaked. That was very temporary so no problem. Other than that very happy that you are providing these chemicals at reasonable prices.

okay, they shipped on time and i received the chemical i ordered at a competitive price..and then it arrived…the bottle was not wrapped in a plastic bag and, admittedly thoughtlessly, i reached in barehanded. perhaps ten minutes later the index finger and thumb of my right hand turned white and began to burn as well as a few blotches on my left hand which i had obviously touched with my right. there was no msds sheet enclosed and when i accessed on on line it recommended rinsing the chemical burn with water for sixty minutes. this proved unnecessary, after an hour or so the white blotches began to fade and the burning had ceased before that. minuscule amount of 34% hydrogen-peroxide on the bottle’s exterior? unknown, however, gloves will be a necessary component of any future unpacking from this vendor.
