Are you looking for a H2O2 mixing chart to dilute 12% H2O2 with water, to get 3% H2O2? You've come to the right place....
To make 3% hydrogen peroxide from 12% hydrogen peroxide, the general mixing guideline is:
1 part 12% hydrogen peroxide plus 3 parts water = 3% hydrogen peroxide. You can use this guideline with any quantity you need to mix.
To make a gallon of 3% peroxide: In a clean gallon container, combine 4 cups of 12% food grade hydrogen peroxide with 12 cups of water. That makes a gallon of 3% hydrogen peroxide.
Here’s the same thing I just said, but in the form of a H2O2 mixing chart:
|USE THIS AMOUNT OF 12% HYDROGEN PEROXIDE||AND THIS AMOUNT OF WATER*||TO MAKE THIS AMOUNT OF 3% HYDROGEN PEROXIDE|
|1 part||3 parts||4 parts|
|1/4 cup||3/4 cup||1 cup|
|1 cup||3 cups||4 cups|
|4 cups||12 cups||1 gallon (16 cups)|
To make measuring and mixing a gallon of 3% peroxide easier, do this:
This eliminates having to measure and count out 12 cups of water each time!
When you make 3% hydrogen peroxide from 12%, PLEASE PLEASE be sure to label every container with so you know what's what.
The label should say HYDROGEN PEROXIDE.
And the concentration: like 3% or 1% or 12%.
This is super important. It can be DANGEROUS if you don't know what concentration you are using. So please please do it.
ALWAYS label all containers clearly, including the concentration (also called percentage or strength).

In the hydrogen peroxide dilution chart, above, I just say “water”. But what kind of water?
That will depend on what you are planning to use the peroxide for. For most purposes, tap water will work.
Here is the exception: If you plan to use the peroxide as an oxygen supplement – to be ingested by anyone (including animals) – then you should consider using distilled water, or filtered water, if at all possible.
Any metals in water will combine with hydrogen peroxide. I’ve read that this is bad stuff to ingest. I’d like to know a lot more than I do about why, and what the level of risk is. I can’t add a lot to this, other than to say that I’ve read that this is risky. How risky I don’t know. But it does make some sense: peroxide is an oxidant. Oxidizing metal creates rust. Drinking rust particles doesn’t seem like a good idea.
I’ve also read that it is bad to ingest peroxide in combination with iron supplements. The reason is the same: iron is a metal.
If you plan to ingest peroxide, you can consider this.
