Hydrogen peroxide (H2O2) is a clear, colourless, odourless liquid. It’s a product of hydrogen and oxygen and is available in many strengths (indicated by the percentage of dilution with water).
One dilution of hydrogen peroxide is 35 percent H2O2 and 65 percent water. Food producers use 35 percent H2O2 for a variety of purposes, including processing cheese and bleaching wheat flour. It’s also used to kill microorganisms in food packaging materials.
This 35 percent dilution is called “food grade” in part because it doesn’t contain certain stabilizers:
- Sodium Stannate
- Tetrasodium pyrophosphate
These stabilizers are found in most other commercially available hydrogen peroxide and should not be ingested.
