Food-grade hydrogen peroxide vs. regular hydrogen 

The key difference between food-grade H2O2 and its regular counterpart lies in their purity levels. 

  • Food-grade hydrogen peroxide — manufactured with stern regulations to ensure that it doesn’t contain certain stabilizers (such as phenol, sodium stannate, acetanilide, and tetrasodium pyrophosphate). It’s often available in concentrations of 12% and 35%.
  • Standard hydrogen peroxide — may include stabilizers and other chemicals that make it unsuitable for internal use. It is commonly found in 3%, 6%, 10%, and 90% solutions.

Regardless of concentration or dilution, hydrogen peroxide should never be consumed.

The uses of food-grade hydrogen peroxide

Food-grade hydrogen peroxide with a 35% concentration is the best to be used internally. It is frequently a part of dental products, is used for food preparation and processing, and is applied as a disinfectant for kitchenware.

Another very popular use of this chemical compound is the preparation of budget-friendly home remedies. 

It’s believed that food-grade hydrogen peroxide kills viruses, infections, and mold, and in its diluted form, might help you handle the following discomforts:

  • Wound cleaning
  • Oral care (teeth bleaching, mouth disinfection, sore throat cushioning)
  • Earwax removal 
  • Sinus infection remedy
