Sodium Percarbonate

Sodium Percarbonate, an addition compound of hydrogen peroxide and sodium carbonate with the formula 2Na₂CO₃·3H₂O₂, is a versatile, environmentally friendly oxidizing agent. It appears as a free-flowing, white, crystalline powder or granules and is a solid source of hydrogen peroxide upon dissolution in water. As a key ingredient in "oxygen" or "color-safe" bleaches, it offers a powerful yet biodegradable alternative to chlorine-based bleaches, making it a cornerstone of modern, eco-conscious cleaning formulations for household and industrial applications.

Description

Core Application Fields
1. Laundry & Cleaning Industry
  This is its most core application field. As an oxygen-based bleaching agent, it is a key component in laundry powder, color-safe bleaching powder, oxygenated bleach, and other products. The active oxygen released when it meets water can break down stubborn stains such as bloodstains, tea stains, and oil stains. It bleaches gently without damaging fabric fibers or fading colors. In linen cleaning for hotels and hospitals, as well as tableware washing, it not only removes dirt efficiently but also avoids the residual hazards of chlorine-based bleaching agents.
2. Aquaculture Industry
  It can be used as a high-efficiency oxygenating agent, releasing oxygen faster than calcium peroxide, which can quickly alleviate the problem of fish and shrimp floating due to oxygen deficiency. Meanwhile, the sodium carbonate released can adjust the pH value of water, reduce the concentration of harmful substances such as ammonia nitrogen and hydrogen sulfide in water, decrease heavy metal content, and play a role in purifying water quality.
3. Emergency & Medical Fields
  When mixed with solids containing catalysts such as copper and iron, adding water can decompose to produce oxygen. It is suitable for emergency oxygen supply in scenarios such as rural households and mining operations, and can also be used in disaster relief such as flood fighting and fire extinguishing. In addition, it can be used as a disinfectant for medical instruments, oral disinfectant, and odor eliminator.
4. Food-Related Fields
  A 1% concentration aqueous solution of sodium percarbonate can keep fruits and vegetables fresh for 4–5 months. When combined with relevant additives, it can also solve the problem of fermentation and deterioration of milk during high-temperature storage and transportation, complying with the relevant standards of the Food and Agriculture Organization of the United Nations.
Other Extended Uses
- In industry, it is used as a bleaching agent and leveling agent in the textile and papermaking industries, avoiding damage to fabrics and paper caused by chlorine-based bleaching agents. It can also be applied in metal surface treatment to remove grease and rust, preparing for processes such as electroplating.
- In the environmental protection field, it can replace hydrogen peroxide as a catalyst for advanced oxidation reactions, used to degrade organic pollutants in water, reduce chemical oxygen demand (COD), and serve as an environmentally friendly sewage treatment agent.
- It can also be used as a teeth whitening agent, kitchen grease remover, wood preservative, etc., applied in various cleaning scenarios in daily life.
Precautions for Use & Storage
- Dissolving in warm water can accelerate the release of active oxygen and improve cleaning efficiency. However, avoid mixing it with chlorine-based bleaching agents or acidic cleaners to prevent the generation of harmful gases.
- Store it in a dry and cool place with sealed packaging, avoid direct sunlight and high-temperature environments, and prevent it from becoming ineffective due to moisture absorption
