Characteristics and technological advantages

Perhydrol (H2O2 35%) is a strong, oxygen-based oxidizer with a wide range of applications. Its action results from the controlled decomposition into water and oxygen, which means it does not leave foreign compounds in the process environment. The product is chlorine-free, does not introduce halides, and usually does not generate persistent by-products.

In industrial practice, a 35% solution serves as a concentrated raw material, which – according to the safety data sheet and manufacturer’s instructions – is diluted to working levels appropriate for a given application. Below is an outline of the most common areas of use.

Applications (industry overview)

Food and beverage industry

• Disinfection of packaging and aseptic lines: Hygiene of surfaces in contact with food (PET/HDPE, multilayer cartons, caps). After contact time and possible neutralization, residues decompose into H₂O and O₂.

• CIP washing / biocidal rinsing of installations: Limiting biofilm and opportunistic microflora in dairies, breweries, juice plants.

• Deodorization / oxidation of difficult organic deposits: In raw material preparation areas, waste logistics, and inter-process wastewater.

Water and wastewater treatment

• Odor removal: Oxidation of sulfides, mercaptans, and other odoriferous compounds in process waters and municipal/industrial wastewater.

• Microbiological control of process water: Supporting disinfection – often in systems with UV or ozone to reduce reagent doses and by-products.

• Advanced oxidation processes (AOP): H₂O₂ + UV/ozone/catalyst for the degradation of micro-pollutants and difficult-to-biodegrade compounds (e.g., phenols, aldehydes, traces of aromatic amines).

Healthcare and professional hygiene

• VHP (vaporized hydrogen peroxide): 35% H₂O₂ as a precursor for generating vaporized hydrogen peroxide for decontamination of cleanrooms, isolators, biosafety cabinets, and temperature-sensitive equipment.

• Disinfection of surfaces and equipment: After preparing working solutions – wide spectrum of action (bacteria, viruses, spores). An alternative to chlorine agents, limiting the formation of chlorinated by-products.

Pulp and paper industry

• Bleaching of pulp and paper: Oxidizing bleaching without chlorine, reducing AOX load in wastewater.

• Decolorization and bleaching of fibers: Cotton, viscose – preliminary stage before dyeing/finishing; control over fiber strength loss by optimizing pH, temperature, and stabilization.

Maintenance and technical cleaning

• Removal of deposits and organic discolorations: Protein-fat stains, soot, secondary discolorations from vegetable oils on compatible material substrates.

• Biofilm reduction: An element of sanitary programs in processing and water installations (tanks, lines, coolers).

Electronics and precision processes

• Micro-etching / surface preparation: Component of baths for processing copper and alloys (PCB/EMS), usually in systems with mineral acids.

• High purity washing: Component of formulations for decontaminating optical and metal components – necessary compatibility tests (aluminum, copper, brass, sinters).

Laboratories, synthesis, and process chemistry

• Auxiliary oxidizer: Reagent for selective oxidations, generating oxygen, supporting termination and cleaning reactions.

• Neutralization of post-reaction contaminants: Oxidation of traces of sulfites, aldehydes, phenols, aromatic amines before directing the stream to purification.

Agriculture and aquaculture (professional applications)

• Hygienization of irrigation systems: Limiting biofilm and microbiological blockages in drip lines; protecting emitters and uniform distribution.

• Disinfection of work surfaces and containers: Packing, sorting, greenhouse farms – as part of GHP/GMP.

Environmental protection and health and safety

• Odor detoxification and emergency neutralizations: Rapid reduction of odors at landfills, in pumping stations, and sedimentation tanks; supporting the decomposition of sulfur and nitrogen compounds with unpleasant odors.

No consumer applications

Perhydrol 35% is a professional product. It is not intended for retail/home use or for the independent preparation of consumer products.

A concentration of 35% is a popular storage standard: it provides high stability and predictability of parameters, while being logistically convenient. It is easy to prepare working solutions with required concentrations for various technological lines.

Work safety: 35% H2O2 is corrosive and strongly oxidizing – personal protective equipment (gloves, eye/face protection, clothing), compatible materials (HDPE, PTFE, acid-resistant steel under certain conditions), and ventilation are required. Avoid contact with catalytic metals, alkaline and organic reducing agents.

How to use (example working dilutions)

Prepare working solutions by slowly adding perhydrol to water (never the other way around), in a cool and well-ventilated place. Examples of calculations:

• 1% H2O2 from 35%: 1 part perhydrol + 34 parts water (1:34).
• 2%: 1 part + 16.5 parts water (≈1:16.5).
• 3%: 1 part + 10.7 parts water (≈1:10.7).

The choice of concentration, temperature, and contact time depends on the process/installation and should result from company procedures, industry standards, or equipment manufacturer documentation. After sanitizing surfaces that come into contact with food – always rinse with potable water.
