Sodium Percarbonate is a biodegradable, beneficial chemical compound used in many industries. It has a chemical formula which is 2Na₂CO₃ · 3H₂O₂, which is an adduct of sodium carbonate (commonly called soda ash or washing soda) and hydrogen peroxide. This combination has created an adduct that, in its solid form, is a concentrated, crystalline powder that will allow for powerful cleaning and bleaching action. It is colorless, crystalline, highly hygroscopic, and water-soluble, which makes it ideal for cleaning and treatment processes.
Sodium percarbonate releases oxygen immediately in solution when the solid is dissolved in water (it is stable in its solid form). This oxygen release allows Sodium Percarbonate a superior oxidizing and cleaning ability with no harmful residue. Its eco-friendly profile, too, has made it a popular choice for manufacturers and customers who want to use a sustainable alternative to chlorine-based products.
Manufacturing Process of Sodium Percarbonate
Traditionally, manufacturers will produce Sodium Percarbonate via a crystallization process. They prepare an aqueous solution of hydrogen peroxide and immediately react it with sodium carbonate under controlled conditions. During the process, they introduce a salting-out agent, typically sodium chloride, to facilitate the nucleation of sodium percarbonate crystals. They then cool and crystallize the solution to yield sodium percarbonate in the form they are aiming for.
In current industrial practice, manufacturers use coating technology to stabilize sodium percarbonate. For applications that require a longer shelf life, they will gravitate towards coated alternatives in order to obtain better resistance to moisture. Depending on their intended applications, they will process the sodium percarbonate into three forms: coated, uncoated, or tablet. Each of these forms has advantages in terms of storing, handling, and performing.
