Sodium percarbonate (Synonyms: sodium carbonate peroxyhydrate, sodium carbonate peroxide, PCS) is a free-flowing crystalline granules. Percarbonate has an active available oxygen content which is equivalent to about 27.5% H2O2. For this, some people name it as solid hydrogen peroxide. It breaks down to oxygen, water and sodium carbonate upon decomposition. 2Na2CO3·3H2O2 → 2 Na2CO3 + 3 H2O2. It's an environmentally safe bleaching agent. Sodium Percarbonate dissolves into water rapidly to release oxygen and provides powerful cleaning, bleaching, stain removal and deodorizing capabilities. It has a wide range of applications in various cleaning products and detergent formulations including heavy duty laundry detergent, all fabric bleach, wood deck bleach, textile bleach and carpet cleaner. Sodium Percarbonate is not suitable for use with silk or wool. Sodium Percarbonate will not remove rust stains or mineral deposits from hard water. Other applications have been explored in personal care formulations, denture cleaners, pulp and paper bleaching process, and certain food bleaching applications. The product also has functions as disinfector for institutional and home applications, oxygen releasing agent in aquaculture, waste water treatment chemical, first-aid oxygen generating agent, etc. sodium Percarbonate donot like sodium perborate, bleaching action only take place at elevated temperatures. To release its bleaching action at lower temperatures, an activator such as Tetra Acetyl Ethylene Diamine must be needed.
Percarbonate is used as an activated oxygen component in detergents, bleaches and cleaning agents. Due to the unsatisfactory storage stability of the uncoated sodium percarbonate in warm/moist surroundings and in the presence of certain detergent and cleaning agent components, percarbonate must be stabilized against the loss of active oxygen. An essential principle of stabilization involves encasing the percarbonate particles in a coating of components having a stabilizing action. Here comes the definition: the coated sodium percarbonate is the crystals coated with single or multiple layers of various substances in order to increase active oxygen stability and optimize storage and ensiling properties.
Benefits • No environmental hazards - breaks down to oxygen, water and sodium carbonate (soda ash) in your wash water. • Color safe and fabric safe. It brightens colors • Continual use will not cause yellowing or graying of cotton fabric • Effective stain removal in a broad range of water temperatures • Lengthens time between linen replacement • Prevents fabric from becoming yellowed or darkened • Does not weaken the strength of fabrics like chlorine bleach • In the laundry Sodium Percarbonate is used to destain, deodorize, and whiten. It is very effective as a laundry presoak for heavily stained articles.
Coated sodium percarbonate is the more commonly commercialized peroxide compared with the uncoated type. But the uncoated product is still the preferred ingredient for simply mixing with enough quantity of soda ash and some surfactants to form the popular oxygen bleaches.
