For textile/paper bleaching, water treatment and disinfection the choice follows your application dose: if you dilute on site and dose at low concentration, the 50% grade is more economical per unit of active substance for shipping and storage; if you want ready dosing and relatively easier handling, the 30% grade fits. In the KORKİMYA portfolio it comes in 30% (~35-40% H2O2 by mass) and 50% (50-55% H2O2 by mass) grades.
Hydrogen peroxide 30% or 50%?
Both grades are the same chemical: hydrogen peroxide (H2O2, CAS 7722-84-1), a colorless transparent liquid. The difference is the H2O2 content by mass and the resulting dilution economics, handling and storage class. Hydrogen peroxide, also known as perhydrol, decomposes into water and oxygen once it has done its oxidizing work, so it leaves no persistent residue in bleaching or water treatment; the choice comes down to which concentration best fits your process dose and logistics.
What is the key difference between 30% and 50%?
The comparison below relies only on the values in the KORKİMYA product data. Assay (H2O2 by mass), typical applications, transport, storage/stabilization, dilution cost logic and packaging in a single table:
Dilution economics: why is 50% cheaper per active substance?
More than half of the 30% grade is water, so a tonne of product carries less active H2O2 and the freight/storage cost per unit of active substance is relatively higher. The 50% grade carries more active substance in the same volume; when brought down to your target bleaching or disinfection concentration by on-site dilution, it lowers total cost per active H2O2. This advantage is clearest in plants with the water infrastructure and dosing automation for dilution, and the gap widens on long-distance shipments.
Which for which application?
Per the KORKİMYA product data the main applications of the two grades overlap; the distinction is concentration and handling preference:
- 30% grade: textile and paper bleaching, water treatment and disinfection, food-packaging sterilisation, electronic surface cleaning and cosmetic production. Lower concentration eases metering and handling; suits processes that want ready dosing.
- 50% grade: cellulose and pulp bleaching, water disinfection, oxidizer in chemical synthesis and semiconductor cleaning. Its active-substance density is advantageous for shipping/storage efficiency and dilution-based dosing.
- If unsure: share your target dose, your on-site dilution capability and your shipping distance; validate the right grade with a sample.
What to watch for in storage and handling?
Sourcing with KORKİMYA
KORKİMYA is a Türkiye-based B2B chemical supplier that sources hydrogen peroxide at 30% and 50% concentrations and in different packaging options. Products are offered as registered under KKDIK; technical data sheets (TDS), certificates of analysis (CoA) and safety data sheets (SDS) are shared on request. To clarify the right concentration, state your target dose, required quantity, dilution capability and delivery point in the request form on the relevant product page; this speeds up the quote and sample process.
Should I choose 30% or 50% hydrogen peroxide?
If you are sensitive to freight/storage cost per active substance and can dilute on site, the 50% grade is advantageous. If ready dosing and relatively easier handling are your priority, the 30% grade fits. Both are the same chemical (H2O2, CAS 7722-84-1); the difference is content by mass and handling.
Is 50% really more economical than 30%?
Per active H2O2 for shipping and storage, yes: the 50% grade carries more active substance in the same volume and less water is shipped. Total cost depends on your on-site dilution infrastructure, dosing automation and shipping distance; the gap widens over long distances.
Can I dilute the 50% grade myself?
Yes, the 50% grade is usually diluted on site to the target bleaching/disinfection concentration. During dilution use clean, compatible equipment and protective gear, avoid heavy metals like copper/iron, and follow the current SDS instructions.
Is storage different for the 30% and 50% grades?
The core principles are shared (cool, ventilated, oxidizer-appropriate storage), but the 30% grade is kept especially away from acids in a cool, dark area, while the 50% grade is kept away from sunlight, flammable/organic materials and heavy metals like copper/iron. The 30% grade has a 6-month shelf life from manufacture.
