What is Javen bleach?
Javen is a solution Sodium hypochlorite (NaOCl) has strong oxidizing properties, producing “free chlorine” for disinfection. Commercial concentrations are usually 6–12% NaOCl.
Easy-to-mix solution form according to usage needs, suitable for everything from household to large-scale water treatment systems.
Benefits & Applications
- Benefits: Fast disinfection, broad spectrum bactericidal. Removes organic stains and whitens fibers.
- Application:
- Water treatment: Swimming pools, factory wastewater, domestic water (output disinfection, algae/microbiological control).
- Industry: Bleaching of paper and fiber; dyeing and washing in textiles; CIP cleaning at the factory.
- Aquaculture & Livestock: Disinfect tanks, ponds, equipment and processing areas.
- Factory: Cleaning ceramics, equipment surfaces, packaging areas.
- Starch processing: Applications in modified starch and cleaning processes.
Product Information & Tools Required
- Main ingredient: Sodium hypochlorite (NaOCl).
- Common concentrations: 6–12% NaOCl (depending on supplier & application).
- Brewing tools: Plastic bucket/tank, measuring cup/can, gloves, goggles, mask.
How to make Javen bleach
Golden rule: Pour Javen into water, do not do the opposite. Mix in a well-ventilated place and use immediately after mixing for best results.
Recommended mixing ratio table
| Purpose | Mixing ratio (Javen : Water) | Usage notes |
|---|---|---|
| Disinfect floors/surfaces | 1:100 | Wet wipe, let dry naturally. Food contact surfaces should be wiped with clean water. |
| Bleaching clothes (chlorine resistant fabrics) | 1:10 | Soak for 5–10 minutes, test on colored/sensitive fabric first. Do not use on wool/silk. |
| Swimming pool – maintain residual chlorine | Depending on volume | Adjust to achieve ~0.5–1.5 ppm Residual chlorine. Check with test kit, add small amounts several times. |
| Disinfection of domestic water | Reference QCVN | Performed by technician; control residual chlorine & contact time prior to use. |
| Wastewater treatment/equipment cleaning | Process | Depends on pollution level & output target. Contact technical to calculate dose & exposure time. |
Quick Brewing Process (How-to)
- Prepare: Ventilated space. Wear gloves, glasses, and mask.
- Measuring water: Pour clean water into the bucket/tub first.
- More Javen: Slowly pour Javen into water, stir well to mix.
- Use now: Activity decreases over time; use within 24 hours is preferred.
Safety notes when using Javen
- Always carry PPE: gloves, glasses, mask. Avoid direct contact with skin/eyes.
- No mix with acid or ammonia because it can generate toxic gas.
- Prepare in a well-ventilated area. Avoid prolonged inhalation of vapors, especially in confined spaces.
- Skin contact: Rinse with plenty of water. Eye contact: Rinse continuously for at least 15 minutes and seek medical attention.
Preservation & concentration stability
- Store in a sealed plastic container, in a cool place. cool dry (<25°C), avoid direct sunlight.
- Keep away from acids, metals, oxidizing/reducing agents to limit decomposition.
- Label receipt date and rotate inventory to ensure quality.
