Sodium Hypochlorite CAS#7681-52-9

Sodium hypochlorite (NaOCl) is a pale green crystalline solid that is unstable in air. It readily dissolves in cold water but decomposes in hot water and has a characteristic sweet aroma. The product is typically available in two concentrations: household liquid bleach containing approximately 5.25 wt% NaOCl, and commercial-grade bleach (sometimes referred to as 15% bleach) containing 150 g/L of available chlorine, equivalent to about 13 wt% sodium hypochlorite.

Product Usage

Sodium hypochlorite, known for its strong oxidizing and disinfecting properties, has a wide range of applications. It can be used for surface disinfection in both public and private settings, including hospitals and homes. It is also effective for disinfecting drinking water, swimming pools, and sewage treatment systems. Additionally, it is suitable for cleaning fruits and vegetables, sanitizing equipment, and disinfecting non-precision medical instruments in the food processing industry.
