Table of Contents
Bleaching Powder 1kg (Calcium Hypochlorite, Ca(OCl)₂) is a high‑purity, 99% pure powder widely used as a powerful disinfectant, bleaching agent, and oxidizing agent. It is a white or grayish‑white powder with a characteristic chlorine odor, used in water treatment, laundry, textiles, and surface disinfection [citation:1][citation:3].
What is Bleaching Powder?
Bleaching Powder (Calcium Hypochlorite) is a white powder that decomposes on contact with water and has the characteristic odor of gaseous chlorine. Its chemical formula is Ca(OCl)₂ with a molecular weight of 142.98 g/mol [citation:2][citation:5]. It is produced by treating slaked lime with chlorine gas:
Ca(OH)₂ + Cl₂ → Ca(OCl)₂ + H₂O [citation:9]
Bleaching powder is a relatively unstable chlorine carrier in solid form. It consists of varying proportions of Ca(OCl)₂, CaCl₂, Ca(OH)₂, and H₂O in its molecular structure. Maximum available chlorine content approaches 39%, with commercial products typically ranging between 24% and 37% [citation:3]. Our product offers 30% – 35% available chlorine, making it suitable for both industrial and household applications [citation:5].

How to Use – For Disinfection & Bleaching
For Surface Disinfection (0.1% Chlorine Solution)
To prepare a 0.1% chlorine solution for surface disinfection:
- Add 3.5 grams of bleaching powder to 1 litre of water [citation:13].
- Stir thoroughly for 10 minutes.
- Allow the solution to rest for another 10 minutes.
- Strain through a cotton cloth to remove solids.
- Use within 24 hours for maximum efficacy [citation:13].
For Water Disinfection (Drinking Water)
For disinfecting drinking water, add approximately 2 grams of bleaching powder per 1000 litres of water, depending on the available chlorine content [citation:15].
For Laundry Bleaching
Add a small amount (approximately 1/2 cup) to a washing machine load of white clothes. Always test on a small area first [citation:15].
