Common Uses
- Disinfectant & Antiseptic: Used in healthcare and sanitation
- Bleaching Agent: For textiles, paper, and hair products
- Water Treatment: Removes contaminants and disinfects
- Chemical Synthesis: Acts as an oxidizer in industrial processes
- Electronics & Aquaculture: Used for cleaning and sterilization
Grades & Purity
- Standard to Super Pure
- Specialty Grades for electronics, pharmaceuticals, and more
It is often referred to as “Food Grade” hydrogen peroxide because it contains a higher degree of purity and typically lacks the stabilizers found in lower-concentration household or industrial grade
The 35% concentration is generally too strong for direct use and is meant to be heavily diluted for most applications. Its primary uses are often industrial or specialized, including:
-
Food Processing: Used as a sterilizing agent for aseptic food packaging (like juice boxes) and for disinfecting food preparation equipment. It’s also used in bleaching certain foods (e.g., wheat flour, cheese whey).
-
Disinfectant/Sanitizer: Used, after proper dilution, for general home cleaning, disinfecting surfaces, or washing produce.
-
Water Treatment: Utilized as an oxidizing agent in water purification and wastewater treatment processes.
