Hydrogen peroxide (H2O2) is a clear, colourless and odourless liquid. Food producers use hydrogen peroxide 35% for a variety of purposes, including processing cheese and bleaching wheat flour. It’s also used for bacterial and fungal control, and for plant/ garden/ botanical cultivation. This product is used by farmers, industrial agriculture companies and gardeners. It is purchased for pest control, treating root rot, pre-treating seeds and to boost plant growth.

This 35 percent dilution is called “food grade” in part because it doesn’t contain toxic stabilizers such as acetanilide, phenol, sodium stanate and tetrasodium pyrophosphate. These stabilizers are found in most other commercially available hydrogen peroxide and should not be ingested.
