Sodium hypochlorite is an essential disinfectant in industrial manufacturing. Discover how to optimize its use to ensure maximum safety, efficiency, and regulatory compliance. As a sodium hypochlorite solution, it is one of the most commonly used industrial chemicals for sanitization across Switzerland and Europe.
The role of sodium hypochlorite in industrial operations
Sodium hypochlorite is widely used in industry for its strong oxidizing and disinfecting properties. Application sectors include food and beverage, water treatment, paper and pulp manufacturing, and the cosmetic and pharmaceutical industries.
It is used for chemical sanitization of complex systems (such as CIP installations), surface disinfection, pipework and tank cleaning, and biofilm control in critical production environments. Thanks to its microbiological efficacy, it is a preferred solution for maintaining product quality and hygiene.

Chemical properties and mode of action
Sodium hypochlorite is an aqueous NaOCl solution that releases active chlorine, effective against pathogens, biofilms, and organic residues. Its performance depends on factors like concentration, pH, temperature, and contact time.
In industrial use, standard concentrations range between 13% and 14%, providing an ideal balance between disinfection power and material compatibility. Modern dosing systems allow for precise control and customization to specific process parameters – a key advantage for production and quality teams.
Regulations and safety standards
The industrial use of sodium hypochlorite is subject to strict safety and handling regulations. Classified as a hazardous substance (ADR), it must be stored, transported, and used under controlled conditions. Best practices include:
- Avoid contact with acids (risk of chlorine gas release)
- Use of PPE: gloves, goggles, and masks where needed
- Protection from heat and UV light
- Compliance with CLP Regulation (EC No. 1272/2008) and REACH

Optimizing sanitization processes
To get the most from sodium hypochlorite, correct dosing and process monitoring are essential. Modern CIP systems benefit from precise active agent delivery, reducing cycle times, water and product consumption, and overall costs.
Targeted dosing also helps maintain microbial load control in a sustainable way. Automation and continuous monitoring enable standardized hygiene results and reduced downtime. ECSA Chemicals supports you with tailored solutions and sector-specific expertise.
Environmental impact and responsible management
Sodium hypochlorite, when correctly used and disposed of, is considered a low-impact disinfectant. Its by-products – water, oxygen, and salts – are generally harmless when legal thresholds are respected.
Responsible management includes:
- Accurate and calibrated dosing
- Minimization of unnecessary emissions
- Proper disposal by licensed operators
