Hydrogen peroxide 50%/60% (CAS 7722‑84‑1) is supplied as a clear aqueous solution with a concentration range of 50‑60 % and a density of 1.20 g/cm³ at 20 °C. Purity of ≥ 99.5 % provides strong oxidising power without chlorine by‑products, making it the preferred bleaching agent for cotton, linen and other natural fibers in the textile industry. Chemically, hydrogen peroxide belongs to the inorganic peroxide family and in solution decomposes to generate hydroxyl radicals that attack chromophoric groups in natural pigments, thereby increasing the optical brightness of the fabric. At 50 % concentration, bleaching to 95 % whiteness is achieved at 60‑70 °C, while 60 % concentration accelerates the process by up to 30 % compared with lower grades, allowing a reduction in energy consumption and cycle time. The peroxide is compatible with standard reactive dyes because it does not react with the amino‑sulfonic groups of the dye molecules, preserving colour uniformity and leaving the mechanical strength of the yarn unchanged. In addition to conventional bleaching, the solution is widely used for pre‑treatment of fabrics before polyester coating, for cleaning non‑woven substrates, and for preparing fibers for advanced functional finishes such as antimicrobial or flame‑retardant treatments. When longer storage stability is required, common stabilisers such as sodium carbonate or phosphate buffers are added to inhibit premature decomposition. Handling guidelines recommend nitrile or butyl rubber gloves, safety goggles with anti‑fog coating, and a minimum ventilation rate of 10 m³/h to keep peroxide vapour concentrations well below occupational limits. Storage in sealed metal containers, protected from direct sunlight and maintained between 5 °C and 30 °C, is essential; periodic gentle agitation helps prevent localized concentration gradients. Upon dilution to a 3 % working solution, the peroxide is employed for fabric pre‑treatment prior to dyeing, improving dye uptake and reducing the need for auxiliary chemicals. Process efficiency is monitored by spectrophotometric methods, which provide precise measurements of whiteness gain and residual oxidative activity. Waste peroxide is neutralised according to local environmental regulations, typically by catalytic reduction, ensuring safe disposal without harmful emissions.

Big bags 1000 kg / Tankers
Store hydrogen peroxide 50‑60 % in its original, tightly sealed containers in a cool, dry, well‑ventilated area, away from direct sunlight and heat sources. Recommended storage temperature is between +5 °C and +25 °C; higher temperatures accelerate decomposition and oxygen release. Shelf life is typically 12‑24 months provided the packaging remains intact. During handling wear chemical‑resistant gloves, safety goggles and protective clothing, avoid contact with organic or alkaline substances, and prevent mechanical damage to the containers.
