Why NaDCC Replaced Old Bleaching Powder

Recommended by WHO, UNICEF, and disaster relief organizations worldwide.

Near-Neutral pH 6.5

Unlike liquid bleach which turns water alkaline (pH 9+) and inactivates chlorine, NaDCC buffers water between pH 6.0 and 7.0 where hypochlorous acid is 95% bactericidal.

Zero Sludge / Chalk

Bleaching powder leaves heavy insoluble calcium carbonate sludge that clogs pipes and fouls tank bottoms. NaDCC dissolves 100% crystal-clear without residue.

36-Month Shelf Life

Liquid hypochlorite loses 50% strength within 30 days in tropical heat. NaDCC effervescent tablets remain stable for 3 to 5 years even under 45°C ambient conditions.

Precise Unit Dose

Eliminates measuring errors. Simply drop 1 tablet per 1,000 Liters of water—no scales, chemical gloves, or messy powder spillage required.
