🚀 Application
Sodium Hypochlorite is a versatile solution used across numerous industries:
1. Water & Wastewater Treatment: Primary disinfectant for drinking water and municipal wastewater.
2. Healthcare & Institutional: Surface disinfection, sanitizing medical equipment, and laundry bleaching.
3. Food & Beverage Processing: Sanitizing processing equipment, surfaces, and produce washing.
4. Pulp & Textile Industry: As a bleaching agent for wood pulp, paper, and textiles.
5. Chemical Industry: As an oxidizing agent in various chemical synthesis processes.
6. Household & Commercial Cleaning: Active ingredient in many household bleaches.

💡 How to use
⚠️ Warning: Handle with care
Always use Personal Protective Equipment (PPE) including gloves, safety goggles, and protective clothing.
- Dilution is Key: Always dilute with cold water before use based on the target concentration (ppm).
- For Surface Disinfection: A typical dilution is 1:100 to achieve a ~1000 ppm solution. Apply by spraying or wiping.
- For Water Treatment: Dosage is controlled by metering pumps based on water flow and quality.
- Mixing Precaution: Never mix with acids or ammonia-based cleaners. This produces toxic chlorine gas.
🌟 Advantages
- Rapid Action: Works immediately upon contact to kill microorganisms.
- Proven Effectiveness: A time-tested, globally recognized disinfectant.
- Cost-Effective: Lower upfront cost per unit of chlorine compared to solids.
- Easy to Apply & Dose: Liquid form allows for precise dosing with pump systems.
- Leaves No Solid Residue: Dissolves completely without leaving insoluble particles.
🌡️ Storage Method
- Store in a Cool, Dark Place: Temperature should ideally be below 20°C (68°F).
- Use Ventilated Areas: Use corrosion-resistant containers like HDPE or fiberglass.
- Short Shelf Life: Plan for FIFO usage. Strength can decrease significantly within weeks.
- Isolate from Incompatibles: Store away from acids, ammonia, and flammables.
❓ FAQ
Q1: What is the shelf life of Sodium Hypochlorite?
A1: Its shelf life is limited. A 12.5% solution stored at 20°C (68°F) can lose 30-50% of its strength within 3-4 months. Higher temperatures and light will accelerate degradation.
Q2: Why does it sometimes have a yellow or brown color?
A2: The pale greenish-yellow color is normal. A darker yellow or brown color can indicate dissolved iron or other metals, or that the product is old and has degraded.
Q3: How does it compare to solid chlorine (e.g., TCCA)?
A3: Liquid Sodium Hypochlorite is faster acting and leaves no residue, but has a shorter shelf life and higher transport costs compared to more stable solid chlorine alternatives.
Q4: Is it corrosive?
A4: Yes, it is highly corrosive. It can damage metals, degrade many plastics, and irritate skin and eyes. Always use recommended materials (HDPE, PVC) and wear PPE.
Q5: Why is there a strong chlorine smell?
A5: The smell indicates the release of chlorine gas due to decomposition. This is common if the product is old, stored improperly, or contaminated.
Q6: Can it be used for drinking water?
A6: Yes, it is a primary disinfectant for municipal drinking water systems, provided it is dosed accurately to maintain safe residual chlorine levels.
