The Eco-friendly Bleaches of Sodium Percarbonate

Sodium percarbonate, or sodium carbonate peroxide is a chemical substance with formula Na ₂H ₃CO ₆. It is an adduct of sodium carbonate and hydrogen peroxide.  It is a colorless, crystalline, hygroscopic and water-soluble solid,which can release oxygen in the event of moisture.  It is sometimes abbreviated as SPC.

Sodium percarbonate is commonly known as solid hydrogen peroxide. As an oxidizing agent,it is widely used in some eco-friendly bleaches and other cleaning products.

Applications in Household Products

One of the primary uses of sodium percarbonate is as an oxygen bleach and stain remover in household products. When dissolved in water, it releases hydrogen peroxide, which acts as a powerful oxidizing agent. This makes it effective for cleaning and brightening fabrics, removing stains from clothing, carpets, and even as an additive in dishwasher and laundry detergents.It is usually coated with substances such as sulfates and silicates to obtain coated sodium percarbonate to improve the storage stability requirements in detergent formulations.

Industrial and Commercial Applications

Beyond household use, sodium percarbonate finds applications in various industrial processes.

It serves as an oxygen source in chemical synthesis, can effectively increase dissolved oxygen in fish pond management.

And as a bleaching agent in paper and pulp industries. Its stable and controlled release of oxygen makes it versatile in formulations where controlled oxidation is necessary.

In the textile industry as a bleaching agent, reduction color development agent, can also be used as a separate disinfectant, deodorant, milk preservative, etc. Sodium percarbonate has the advantages of non-toxic, odorless, pollution-free, and has the characteristics of bleaching, sterilization, washing, and good water solubility.

Environmental Benefits

Unlike traditional chlorine-based bleaches, sodium percarbonate breaks down into oxygen, water, and sodium carbonate, leaving no harmful residues or by-products. This eco-friendly characteristic has made it a preferred choice in green cleaning products and initiatives aimed at reducing environmental impact.

While sodium percarbonate is generally safe for household use and considered biodegradable, it requires proper handling to avoid inhalation and contact with skin or eyes. Like any chemical compound, it should be stored in a cool, dry place away from incompatible materials.
