Sodium percarbonate, commonly known as solid H202, is an addition compound of H202 and sodium carbonate. After decomposition, it produces oxygen, water and sodium carbonate. Its effective active oxygen content is equivalent to 27.5% H202. Sodium percarbonate not only has the function of liquid H202, but also rapidly decomposes and releases oxygen at low water temperature to achieve functions such as bleaching, decontamination, sterilization, and deodorization, and at the same time decomposes to generate sodium carbonate, which can increase the pH value of water and reduce The ability of calcium and magnesium ions in hard water to soften the water. In addition, as pH increases, soils and fibers are more negatively charged, thereby increasing the repulsion between soil and fibers, improving bleaching and washing performance. Decomposition products of sodium percarbonate: Oxygen, water and sodium carbonate are naturally occurring substances and have no negative impact on the environment, so sodium percarbonate is a very environmentally friendly high-performance low-temperature oxygen-based bleaching agent.

Sodium percarbonateCAS 15630-89-4 Usage

This product is used as raw material for low-phosphorus and non-phosphorus washing powder. It is used as a rinse agent and a reducing color developer in the textile industry. It can also be used as a disinfectant and deodorant alone.

Sodium percarbonate is commonly known as solid H202
. As a classic chemical product, the industry began to produce it more than 100 years ago. With the growth of social needs, especially the needs of ecological environmental protection, H202 has become more popular in recent years and is called "green oxidant". Sodium percarbonate is widely used in a variety of industrial and consumer products, such as laundry detergents, color bleaching powders, wood floor cleaners, carpet cleaners, and other household and personal care formulations. Sodium percarbonate can be made into various disinfectants and oxygen supply agents for oxygen supply in fish ponds, industrial wastewater treatment, medical disinfection/first aid, etc. In addition, sodium percarbonate can also be used in food bleaching, pulp bleaching and textile printing and dyeing.
Sodium Percarbonate
Washing auxiliaries: Sodium percarbonate has the functions of bleaching, sterilization and disinfection at the same time of washing and decontamination. It has become the development trend of detergents. development in this regard. Because sodium percarbonate is odorless and non-toxic, it is easy to dissolve in cold water, and has strong detergency. After dissolving in water, it can release oxygen and play a variety of functions such as bleaching and sterilization, which is in line with the development trend of modern detergents. The application of sodium percarbonate in detergent production is increasing. At present, sodium percarbonate has been widely used as household and industrial washing, bleaching, bactericide, and used in the production of synthetic fibers, animal fibers, synthetic resin fibers, pulp fat and other fields. Good bleaching effect, no damage to the fabric, no yellowing. For example, in Japan's heavy-duty color bleaching washing powder, the addition amount of sodium percarbonate is 10%; the common enzyme bleaching washing powder in foreign countries, the addition amount is 8%; Japan's new detergent for stain removal, the addition amount is 20%; Dust-proof bleached laundry detergent, added at 8%. Since the 1980s, the demand for detergents in developed Western industrialized markets has grown at an average annual rate of 10%. In China, the application of sodium percarbonate to detergent production is in its infancy, and some manufacturers have begun to combine sodium percarbonate with other effective detergent auxiliaries. In the face of fierce market competition, it is hoped to add sodium percarbonate to improve the performance of washing powder, especially the production of low-phosphorus or no-phosphorus washing powder. direction development.
Sodium Percarbonate
Medical and health care: Mix sodium percarbonate with a solid substance containing polyvinyl acid and any compound catalyst such as Cu, Fe, Co, Mn, etc. When oxygen is used for emergency use, add an appropriate amount of water to decompose oxygen, which is simple and convenient. Oxygen supply is large. This oxygen source is suitable for family (especially rural family),  underground construction and mining, flood control, fire fighting and disaster relief and other emergency occasions. It is an excellent first aid oxygen supply. According to conservative estimates, the sodium percarbonate used for medical oxygen supply in Beijing and Tianjin alone needs about 400 tons per year, and some exported sodium percarbonate is also used in this aspect. Sodium percarbonate is also a bactericidal disinfectant, which can kill common germs such as Escherichia coli, staphylococcus, and hepatitis virus. It can be used as sterilizer and disinfectant in hospitals and public places, denture cleaner, tableware and fruit disinfectant, soap disinfectant, etc.
Sodium Percarbonate
Others: Sodium percarbonate can be used for food preservation and disinfection, 1% sodium percarbonate aqueous solution can keep fruits and vegetables in storage for 4-5 months without deterioration. It has been widely used in the food industry in the West, and China has also formulated industry standards for the food additive sodium percarbonate in accordance with the standards of the United Nations Food and Agriculture Organization to better guide enterprises to use sodium percarbonate and promote its consumption in the food industry. . In addition, sodium percarbonate can replace Ca2O2 as an oxygen generator in aquaculture, and the oxygen release rate is significantly higher than that of Ca2O2, and it can supply oxygen to fish, shrimp, crabs and other organisms during storage and transportation. With the continuous development of my country's aquaculture industry, the amount of sodium percarbonate in this area will show an upward trend year by year. Sodium percarbonate can be used as a finishing agent for textiles, printing and dyeing. Unlike 
bleaching, which has the disadvantage of easy fading, it is suitable for rinsing and finishing of synthetic fibers, animal fibers, synthetic resin fibers and fibers treated with optical brighteners that are not suitable for  bleaching. Sodium percarbonate can be used as an oxidant in the reaction of aldehyde group conversion to phenolic hydroxyl group, organoborane oxidation, nitrile hydrolysis, thioether and amine oxidation, olefin epoxidation, ketone oxidation, α-diketone cleavage oxidation and other reactions. In addition, sodium percarbonate can also be used as metal surface treatment agent, electroplating detergent, sewage treatment agent and polymer polymerization control agent.
