Comparison of NaOCl (Javen) vs. Cl₂ vs. H₂O₂ — Which Disinfectant Should You Choose?

NaOCl (Javen, CAS 7681-52-9): Safe, easy to use, low cost, no pressure equipment required. Suitable for treating potable water (QCVN 01), swimming pools, food products, and hospitals. Limitations: Rapid decomposition when exposed to light or high temperatures.
Cl₂ (Chlorine Gas): Highly effective for large volumes of wastewater; lower costs at large scales. However, it is hazardous during transport and storage, requires specialized equipment, and poses a risk of toxic leaks.
H₂O₂ (Hydrogen Peroxide): Produces no organic Chlorine byproducts and is safer for the environment. However, it is more expensive than NaOCl, and its disinfection effectiveness depends on pH and temperature.

Recommendation: For most applications in Vietnam (water treatment, swimming pools, food processing, aquaculture), NaOCl 10–12% is the optimal choice in terms of cost, safety, and compliance with QCVN standards.

Important safety precautions when diluting Javel (MSDS NaOCl):

Do not mix Javel with acids (vinegar, HCl, acid-based toilet cleaners): the reaction releases toxic chlorine gas.
Do not mix Javel with ammonia : this produces toxic chloramine gas, which can cause respiratory damage.
Do not mix Javen with hot water : high temperatures decompose active chlorine.
Always wear long-sleeved gloves

Frequently Asked Questions (FAQ)

What is Javel? What is NaOCl?

Javel is the common name for Sodium Hypochlorite (NaOCl), code CAS 7681-52-9. It is a pale yellow liquid solution with alkaline properties (pH 11–13), containing active Cl ranging from 5% to 12% depending on concentration. Javen is produced by reacting Cl₂ gas with NaOH solution. Formula: 2NaOH + Cl₂ → NaCl + NaOCl + H₂O. Loc Thien supplies Javen NaOCl, which complies with QCVN 01:2009/BYT and comes with complete CoA, MSDS, and CO/CQ.

What are the different concentrations of Javen 5%, 10%, and 12% used for?

Javen 5%: Used for household disinfection and mild fabric bleaching. Javen 10%: The most versatile—for potable water treatment (QCVN 01:2009/BYT), swimming pools, food processing, and aquaculture. Javen 12%: Industrial Wastewater Treatment (QCVN 40:2011), Disinfection in Hospitals, Operating Rooms, and High-Risk Areas. All three concentrations are available as CAS 7681-52-9, differing only in active chlorine content.

What is the dilution ratio for Bleach (Sodium Hypochlorite) used to disinfect drinking water?

According to QCVN 01:2009/BYT, drinking water must maintain a residual Chlorine level of 0.2–0.5 mg/L (ppm). To achieve 0.5 ppm in 1 m³ of water (1,000 L), approximately 50 mL of Javel 10% or 42 mL of Javel 12% is required. However, the actual dosage depends on the quality of the source water and the contact time—it should be verified using a residual chlorine tester. Loc Thien offers free technical consultation: 0979 891 929.

How should Javel be diluted for Swimming Pool treatment?

Public Swimming Pools must maintain a residual chlorine level of 1–3 ppm in accordance with QCVN 26:2016/BYT. Use Javel 12% (NaOCl CAS 7681-52-9): pump directly into the circulation system. The initial dose is typically 2–4 L of Javel 12% per 100 m³ of water; the maintenance dose is 0.5–1 L per 100 m³ per day, depending on bacterial load and temperature. Check residual chlorine daily using a DPD test kit. An automatic dosing pump is recommended for precise control.

NaOCl vs. Cl₂ vs. H₂O₂ — which disinfectant should you choose?

NaOCl (Javen, CAS 7681-52-9): safe, easy to use, low cost, no pressure equipment required, suitable for most applications in Vietnam (QCVN 01, swimming pools, food, hospitals). Cl₂ (chlorine gas): highly effective on a large scale but hazardous during transport and requires specialized equipment. H₂O₂: more environmentally friendly but more expensive than NaOCl, and its effectiveness depends on pH. Conclusion: NaOCl 10–12% is the optimal choice for most businesses in Vietnam.

Does industrial Javen come with an MSDS, CO/CQ, and CoA?

Yes. Loc Thien provides a complete set of legal documents for Javen NaOCl (CAS 7681-52-9): CO/CQ (Certificate of Origin/Quality), CoA (Certificate of Analysis—analysis of active chlorine concentration, pH, and specific gravity), MSDS (Material Safety Data Sheet compliant with GHS standards), and QCVN 01:2009/BYT certification for water treatment products.
