Product Descriptions：

Sodium percarbonate is obtained through the reaction of sodium carbonate with hydrogen peroxide, which can be achieved via dry, spray, and wet processes. The dry method comprises spraying of aqueous hydrogen peroxide solution on solid sodium carbonate. A solid-liquid reaction yield sodium percarbonate. In the spray process, sodium percarbonate is created by a fluid bed process. Solutions of hydrogen peroxide and sodium carbonate are sprayed into a drying chamber to dehydrate. The wet process forms sodium percarbonate by crystallization.

The final product appears in the form of a white, powdered, or granular solid oxidizer.

Exposure of sodium percarbonate to impurities can lead to decomposition, resulting in the liberation of oxygen gas, heat, water, and possibly steam. These impurities include strong acids, bases, and transition metals such as copper, manganese, or chromium. Systems used for transport and storage of sodium percarbonate must be adequately vented with enough emergency venting capacity to allow the system’s contents to withstand a decomposition event without consequences.

Application:

Sodium percarbonate is utilized primarily as a bleaching agent in cleaning products, eco-friendly bleaches, and as a laboratory source of anhydrous hydrogen peroxide. It is widely used as anionic surfactant in household detergents, such as washing powder, laundry detergent liquid, dishwashing liquid and other daily cleaners, pH regulators and water treatment products, water treatment chemicals, cosmetics, and personal care products, metal and non-metal surface treatment products, metalworking fluids, textile treatment products, dyes, and water softeners. Additionally, other uses include fungicides, algaecides, chemical synthesis, and environmental applications.
