Javelin Water

Javelin Water is a solution of 15 to 17% Sodium Hypochlorite. depending on the application, the percentage of Sodium Hypochlorite can have a wider range . It is a solution used for disinfection, bleaching and Eliminate odors. It’s color is close to yellow with spicy taste and smell. Javelin is a chlorinated bleach that also has antiseptic properties.

Sodium Hypo solution is unstable and decomposes in the presence of light and heat to NaCl and oxygen. In order to eliminate loss of the material, It should be stored in opaque containers away from heat.

Safety tips

Sodium Hypochlorite vapors cause severe eye and skin irritation. In general, chlorine vapors can cause eye irritation. In severe cases, contact with the skin may cause severe burns. Inhalation of this gas can damage the respiratory system. If you inhale this gas, find a place with fresh air and free of these vapors. In more acute conditions it is necessary to use oxygen capsules. Eating this substance may cause pain and burning in the mouth and Stomach, shock, anesthesia and in very severe cases death. It can have a destructive effect on the ozone layer due to the possibility of releasing Chlorine gas.
