Hydrogen peroxide (H2O2) is a powerful oxidizing and bleaching chemical that decomposes into water and oxygen, leaving no persistent residue. In industry it is used most in textile and pulp bleaching, water treatment and disinfection, chemical synthesis and electronics/semiconductor cleaning. It is sold at different concentrations; in the KORKİMYA portfolio it is supplied as a colorless transparent liquid in 30% (~35-40% H2O2 by mass) and 50% (50-55% H2O2 by mass) grades.

What is hydrogen peroxide (H2O2)?

Hydrogen peroxide is an inorganic oxidizer with the formula H2O2 and CAS number 7722-84-1. It is supplied as a colorless transparent liquid and is miscible with water in all proportions. Its key advantage is that, once it has done its oxidizing work, it decomposes into water (H2O) and oxygen (O2); unlike chlorine-based bleaches it therefore leaves no persistent salt or organic-halogen residue. That property makes it a preferred choice for both bleaching and water-treatment applications.

Pure H2O2 is not placed on the market; it is always supplied as an aqueous solution at a defined concentration. As concentration rises, shipping efficiency per unit of active substance improves, but reactivity and handling requirements increase too. The two most common industrial grades are 30% and 50%.

Key applications

The industrial value of hydrogen peroxide comes from its ability to oxidize and bleach without leaving residue. Based on the KORKİMYA product data, its main applications are:

  • Textile and cellulose bleaching: bleaching of natural and synthetic fibres with a lighter environmental footprint.
  • Paper and pulp bleaching: oxidizer in chlorine-free (ECF/TCF) bleaching processes.
  • Water treatment and disinfection: oxidation of waste and process water, odour and organic-load reduction.
  • Chemical synthesis and process chemistry: oxidizing reagent in intermediate and specialty-chemical production.
  • Electronics and semiconductor sector: in surface cleaning and treatment steps.
  • Food industry: sterilisation of packaging and equipment (at permitted dosage).
  • Cosmetics and personal care: oxidizing/bleaching component in specific formulations.

Technical properties and concentration (30% vs 50%)

Both grades are the same chemical (H2O2, CAS 7722-84-1) and both are colorless transparent liquids; the difference is in the hydrogen peroxide content by mass and the related handling/logistics properties. The comparison below relies only on the values in the KORKİMYA product data:

Which concentration should you choose?

The 30% grade is supplied in IBC tanks, metal/plastic drums and tankers (bulk) per the product data, and suits textile/paper bleaching, water treatment, food-packaging sterilisation, electronic surface cleaning and cosmetic production. Its lower concentration makes dosing and handling relatively easier.

The 50% grade has a higher active-substance density, so it is advantageous for shipping and storage efficiency per unit of active H2O2; per the product data it is supplied in 1 m3 HDPE containers (~1,160 kg) or as bulk shipment and is used for cellulose/pulp bleaching, as a chemical-synthesis oxidizer, for semiconductor cleaning and water disinfection. The right choice depends on your dosing infrastructure, your plant's water tolerance and shipping distance. If you are unsure which grade fits a given application, validation with a sample is recommended.

Safe storage and handling

Hydrogen peroxide is a strong oxidizer and contact with flammable/organic materials can intensify a fire. Store the 30% grade away from acids and acid-forming substances, in a cool, well-ventilated and dark area. Keep the 50% grade away from direct sunlight, flammable and organic materials, and avoid contact with copper, iron and other heavy-metal compounds, which accelerate decomposition. Always use protective gloves, goggles/face shield and ventilation, and follow the product's current Safety Data Sheet (SDS).
  • Store in a cool, well-ventilated area away from direct sunlight.
  • Keep separate from acids, flammable materials and organic substances.
  • Avoid contact with heavy metals (copper, iron) and incompatible catalysts; they accelerate decomposition.
  • Account for a limited decrease in H2O2 content during storage (up to about 2.5%) and observe the shelf life.
  • Use vented/suitably closed containers to guard against pressure build-up.

What is the difference between 30% and 50% hydrogen peroxide?

Both are the same chemical (H2O2, CAS 7722-84-1) and a colorless transparent liquid; the difference is the H2O2 content by mass: the 30% grade is about 35-40% and the 50% grade is 50-55% H2O2. The 50% is more efficient for shipping/storage per unit of active substance, while the 30% is relatively easier to handle.

How is hydrogen peroxide stored safely?

In a cool, well-ventilated area away from direct sunlight; kept away from acids, flammable/organic substances and heavy metals such as copper and iron, which accelerate decomposition. Follow the current SDS instructions and the shelf life.
