The Sodium HypoChlorite is a chemical widely used, known for the disinfectant, bleaching and cleaning properties. Generally, it is found in domestic and cleaning products, being effective when sanitising and disinfecting surfaces. However, the effectiveness of Hypochlorite might decrease within time, especially when the levels of concentration are up to 12% - 15%. A good storage is crucial to maintain its power and maximise the shelf-life of Sodium Hypochlorite.
Sodium hypochlorite Stability at 12% - 15%
When concentrated at 12% -15%, the sodium hypochlorite is highly reactive and it can degrade in lower concentrations. The higher the concentration, the faster it decomposes in salt and oxygen. This degradation decreases the effectiveness of the chemical over time, especially when exposed to certain environmental factors. Under the right storage conditions, the sodium hypochlorite can maintain its effectiveness for up to two to three months.
Factors affecting the shelf-life of the Sodium Hypochlorite
Several factors might affect significantly the shelf-life of the Sodium Hypochlorite at 12% - 15% some of this factors are:
Shelf-Life
When correctly stored, in a fresh and dark area with sealed containers, the sodium hypochlorite at 12% -15% can last up to 60 to 90 days. After this time, the concentration will decrease, with a typical solution of 12% decreasing 10% after three months. Over time, the decreasing phase will continue, making it less effective.
Summary
Sodium Hypochlorite at 12-15% has a short shelf-life due to its instability. The right storage as keeping it fresh, away from light and in sealed containers is essential to maximise the shelf-life. The chemical can last effectively up to 3 months when packed and stored as it should be, this chemical is reliable to use in a short time as a disinfectant and for cleaning products.
