General data

Sodium lignosulfonate is a natural, eco-friendly anionic surfactant derived from wood pulp (lignin) during paper production. It is a brown, water-soluble powder used widely as a dispersant, binder, and emulsifier in construction (cement water-reducer), agriculture, ceramics, mining, and, as a coating in pharmaceuticals, offering high-strength bonding and reduced viscosity. 

Key Characteristics:

• Source: Produced from wood pulp, making it a renewable, natural polymer.
• Properties: High dispersing ability, surface activity, water-solubility, and strong bonding capabilities.
• Form: Typically available as a brown powder or liquid.
  
• Key Uses and Applications:
  • Construction & Cement: Acts as a water-reducing agent (superplasticizer) in concrete, improving workability, flowability, and strength while reducing cement usage.
  • Agriculture: Used as a soil conditioner, plant growth promoter, and for dust control. It also enhances the effectiveness of pesticides and fertilizers.
  • Industrial Binders: Acts as a binder in animal feed pellets, ceramic production, and in manufacturing refractory materials.
  • Dispersant: Used to disperse coal particles in coal-water slurries, reducing viscosity for easier transportation. Also used for dyes, pigments, and carbon black.
  • Oil Drilling: Used in oil well drilling fluids to manage viscosity and prevent mud flocculation.
  • Other Uses: Pharmaceutical tablet coating, paper production defoamer, and leather processing.
• Benefits:
  • Eco-Friendly: Derived from renewable, natural sources.
  • Efficiency: Improves energy efficiency in industrial processes like coal slurries.
  • Performance: Increases the durability of construction materials.
