Product Description

• Detergent Industry: It is often used as an additive in detergents. It can form soluble chelates with metal ions, effectively preventing the formation of precipitates and increasing the cleaning power. It is also used as a soap synergist to prevent the oil in bar soap from precipitating and frosting. It has a strong emulsifying effect on lubricants and fats and can be used to adjust the pH value of soap solutions.
• Food Industry: It is used as a food additive. In the processing of meat products, it can be used as a water - retaining agent to improve the tenderness and viscosity of the finished product and increase the yield. For example, adding it to duck meat and chicken can improve the water - retaining rate of meat products and the quality and flavor. In fish, it can significantly enhance the deformation, water - holding capacity, and water distribution of fish - crab meat protein gels. It can also be used as a softener to soak or blanch fruits and vegetables, maintaining their soft characteristics by reducing the hardness of the skin.
• Other Industries: It can be used as a water softener in industrial water treatment, a pre - tanning agent in leather making, a dyeing assistant, a dispersant in the preparation of suspensions in the paint, kaolin, magnesium oxide, and calcium carbonate industries, and a drilling mud dispersant. In the paper - making industry, it is used as an anti - oil agent. In addition, due to its nitrogen and phosphorus content, it can be used as a flame retardant in fire - extinguishing agents, paper - based materials, coatings, plastics, etc. It can also be used as a non - toxic cross - linking agent to improve the pH value and thermal stability of copolymers.
