Food grade hydrogen peroxide

Anyone know where I can find & purchase a gallon or two here in LA. I'm in the Fairfax area, but don't mind a bit of a drive. Just not to the 909, or some such nonsense.

Thanks in advance.

  1. Is food grade the same solution that drug stores sell as opposed to beauty supplies? If so, I'd think the pharmacist could order it in for you. I'm in over my head on this one so just ignore me if I'm being stupid?

      It's a pretty specific thing. The drones at CVS would point you to the standard stuff, which is not great, and full of metallic stabilizers. Fine for healing a cut, but not for use as a cleanser for kitchens. Thanks, regardless.

        fwiw, I found diluted food grade peroxide at Eherwon Grocery on Beverly (behind the Grove), but am still in search of the gallon-size, pure stuff.

        thanks again, chowhounders.

          What you want isn't really the "pure stuff", but is diluted with water down to below about 10% strength. The "pure stuff" is highly reactive (i.e., in the presence of a catalyst, it's literally rocket fuel) and would be available, I suspect only from a chemical company, under "hazardous substance" regs. and restrictions.

            From the link below:

            Grades of Hydrogen Peroxide
            Hydrogen peroxide is available in various strengths and grades.

            A) 3.5% Pharmaceutical Grade: This is the grade sold at your local drugstore or supermarket. This product is not recommended for internal use. It contains an assortment of stabilizers which shouldn't be ingested. Various stabilizers include: acetanilide, phenol, sodium stanate and tertrasodium phosphate.

            B) 6% Beautician Grade: This is used in beauty shops to color hair and is not recommended for internal use.

            C) 30% Reagent Grade: This is used for various scientific experimentation and also contains stabilizers. It is also not for internal use.

            D) 30% to 32% Electronic Grade: This is used to clean electronic parts and not for internal use.

            E) 35% Technical Grade: This is a more concentrated product than the Reagent Grade and differs slightly in that phosphorus is added to help neutralize any chlorine from the water used to dilute it.

            F) 35% Food Grade: This is used in the production of foods like cheese, eggs, and whey-containing products. It is also sprayed on the foil lining of aseptic packages containing fruit juices and milk products. THIS IS THE ONLY GRADE RECOMMENDED FOR INTERNAL USE. It is available in pints, quarts, gallons or even drums. Various suppliers are mentioned later in this article.

            G) 90%: This is used as an oxygen source for rocket fuel.

            Only 35% Food Grade hydrogen peroxide is recommended for internal use. At this concentration, however, hydrogen peroxide is a very strong oxidizer and if not diluted, it can be extremely dangerous or even fatal. Any concentrations over 10% can cause neurological reactions and damage to the upper gastrointestinal tract. There have been two known fatalities in children who ingested 27% and 40% concentrations of H202. Recently, a 26 month old female swallowed one mouthful of 35% H202. She immediately began vomiting, followed by fainting and respiratory arrest. Fortunately, she was under emergency room care and although she experienced erosion and bleeding of the stomach and esophagus, she survived the incident. When she was re-examined 12 days later, the areas involved had healed (J Toxicol Clin Toxicol 90;28(1):95-100).

            35% Food Grade H202 must be

            1) handled carefully (direct contact will burn the skin--immediate flushing with water is recommended).

            2) diluted properly before use. 3) stored safely and properly (after making a dilution the remainder should be stored tightly sealed in the freezer).

            One of the most convenient methods of dispensing 35% H202 is from a small glass eye dropper bottle. These can be purchased at your local drugstore. Fill this with the 35% H202 and store the larger container in the freezer compartment of your refrigerator until more is needed. Store the eye dropper bottle in the refrigerator. The generally recommended dosage is outlined in the chart below. The drops are mixed with either 6 to 8 ounces of distilled water, juice, milk or even aloe vera juice or gel. (Don't use chlorinated tap water to dilute the peroxide!)

            Suggested Protocol
            The program outlined is only a suggestion, but it is based on years of experience, and reports from thousands of users. Those who choose to go at a slower pace can expect to progress more slowly, but that certainly is an option. The program is not carved in stone and keep in mind that it can be adapted to fit individual needs. Individuals who have had transplants should not undertake an H202 program. H202 stimulates the immune system and could possibly cause a rejection of the organ.


            1. re: RicRios

              OP states desired use is for "cleanser for kitchens." Perhaps that's not the grade that's really appropriate? That was a very interesting post, RicRios.

              1. re: c oliver

                If the OP is looking for a "green" kitchen sanitizer, this L.A. Times article points (my opinion) in the right way:

    2. Love that the internal/personal use thing got brought up. I'm getting rid of all haz chem cleaners at both home & work, and yes, also wish to begin a LIGHT internal regimen.

      You can find the stuff online - have a look at This is who I'll end up ordering from when I do the bulk order. You're right, SLB, the stuff is not to be messed with, but when diluted at home with distilled water, you're looking at a much healthier way to clean and sanitize.

      Done EXTENSIVE reading on the internal uses, and I'm looking forward to it, along with some other health changes I'm making.

      Thanks for the time, you'se guys.
