Comparison of NaOCl (Javen) vs Cl₂ vs H₂O₂ — Which Disinfectant to Choose?

NaOCl (Javen, CAS 7681-52-9): Safe, easy to use, low cost, no pressure equipment required. Suitable for domestic water treatment (QCVN 01), swimming pools, food, and hospitals. Limitations: rapid decomposition under light and high temperatures.
Cl₂ (Chlorine Gas): Highly effective for large-scale wastewater treatment, lower cost at large scale. However, dangerous during transport/storage, requires specialized equipment, and poses toxic leakage risks.
H₂O₂ (Hydrogen Peroxide): No organic chlorine byproducts, more environmentally friendly. However, higher cost than NaOCl, and effectiveness depends on pH and temperature.

Recommendation: For most applications in Vietnam (water treatment, swimming pools, food, aquaculture), 10-12% NaOCl is the optimal choice for cost, safety, and QCVN compliance.

Critical Safety Notes When Diluting Javel (NaOCl MSDS):

Do not mix Javel with acids (vinegar, HCl, toilet cleaners with acid): releases toxic chlorine gas.
Do not mix Javel with ammonia: produces toxic chloramine gas, harmful to respiratory systems.
Do not dilute Javel with hot water: high temperatures degrade active chlorine.
Always wear rubber gloves and goggles when handling (per NaOCl MSDS CAS 7681-52-9).
Use diluted solutions immediately; do not store for more than 24 hours.
Prepare in well-ventilated areas.

Frequently Asked Questions (FAQ)

What is Javen? What is NaOCl?

Javen (or Javel) is the common name for Sodium Hypochlorite (NaOCl), CAS 7681-52-9. It is a light yellow liquid solution, alkaline (pH 11–13), containing 5% to 12% active chlorine depending on concentration. Javen is produced by reacting chlorine gas (Cl₂) with sodium hydroxide (NaOH). Formula: 2NaOH + Cl₂ → NaCl + NaOCl + H₂O. Loc Thien supplies QCVN 01:2009/BYT-compliant NaOCl with full CoA, MSDS, CO/CQ.

What are 5% vs 10% vs 12% Javen used for?

5% Javen: for household disinfection, light fabric bleaching. 10% Javen: most versatile — domestic water treatment (QCVN 01:2009/BYT), swimming pools, food, aquaculture. 12% Javen: industrial wastewater treatment (QCVN 40:2011), hospital disinfection, high-risk areas. All three concentrations share CAS 7681-52-9 but differ in active chlorine content.

What is the dilution ratio for Javen in drinking water treatment?

Per QCVN 01:2009/BYT, drinking water requires 0.2–0.5 mg/L (ppm) residual chlorine. To achieve 0.5 ppm in 1m³ (1000L) water, use ~50ml 10% Javel or 42ml 12% Javel. Actual dosage depends on source water quality and contact time — test with residual chlorine meters. Loc Thien offers free technical advice: 0979 891 929.

How to dilute Javen for swimming pools?

Public pools require 1–3 ppm residual chlorine per QCVN 26:2016/BYT. Use 12% Javel (NaOCl CAS 7681-52-9): inject directly into circulation systems. Initial dose: 2–4L 12% Javel / 100m³ water; maintenance dose: 0.5–1L/100m³/day depending on bacterial load and temperature. Test residual chlorine daily with DPD kits. Automatic dosing pumps are recommended for precision.

NaOCl vs Cl₂ vs H₂O₂ — which disinfectant to choose?

NaOCl (Javen, CAS 7681-52-9): safe, easy to use, low cost, no pressure equipment, ideal for most Vietnamese applications (QCVN 01, pools, food, hospitals). Cl₂ (chlorine gas): high efficiency for large-scale wastewater but hazardous during transport, requires specialized equipment. H₂O₂: more eco-friendly but costlier than NaOCl and pH/temperature-dependent. Conclusion: 10–12% NaOCl is optimal for most businesses in Vietnam.

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

Yes. Loc Thien provides full documentation for NaOCl (CAS 7681-52-9): CO/CQ (Certificate of Origin/Quality), CoA (Certificate of Analysis — active chlorine %, pH, density), MSDS (Material Safety Data Sheet per GHS), and QCVN 01:2009/BYT certification for water treatment. Documents are available within 24 hours upon request.
