Sodium Percarbonate 
Solid Active Oxygen Agent

Sodium Percarbonate is a solid, environmentally friendly and highly stable bleaching agent, which combines the properties of hydrogen peroxide and sodium carbonate and provides an excellent bleaching and oxidizing performance as well as alkalinity. Remarkable features of crystalline Sodium Percarbonate are excellent dissolution rate and low tendency for segregation in formulation.
Sodium Percarbonate is used, for example, as a bleaching and oxidizing component in laundry powders and tablets, automatic dishwashing detergents, bleach boosters and denture cleaning agents.
Due to the high dissolution rate Sodium Percarbonate is well suited for formulations demanding rapid availability of active oxygen.
Outside detergent applications it can be used as a source of alkaline hydrogen peroxide, for example, in fish farming, as an oxidizing agent in the textile industry or as a foaming agent (source of gaseous oxygen).

Storage
Sodium Percarbonate  has to be stored in original ventilated paper bags or big bags or dedicated silos, vented and protected from direct sun in cool and dry areas. It is important to keep Sodium Percarbonate C55 protected from all types of contamination and away from combustible/oxidizable materials.

Safe handling
While working with Sodium Percarbonate, always wear safety goggles and gloves. Use clean, dry silos and equipment of compatible materials. Do not return unused product to original container and do not use spilled (contaminated) material again. In case of dust, wear eye and respiratory protection. Avoid all contact with combustible material, e.g. organic material or oxidizable products.

Hazards
Sodium Percarbonate is classified as an oxidizer. Improper handling may result in rapid decomposition. Decomposition of Sodium Percarbonate can liberate oxygen and steam which can lead to pressure build-up when stored in hermetically closed systems.
