Calcium lignosulfonate

Calcium lignosulfonate (CAS 8061-52-7), or CLS, is a natural polyelectrolyte derived from sulfite pulping of wood.

Where is Calcium lignosulfonate used?

• Concrete and cement: water-reducing admixture that improves workability without raising the water-to-cement ratio
• Animal feed: pellet binder that improves pellet durability and reduces fines during handling and transport
• Agricultural formulations: dispersant for pesticides and micronutrients, improving spray coverage and soil application uniformity
• Mining: dust suppressant and ore flotation modifier
• Water treatment: flocculation properties aggregate suspended solids for easier removal
• It functions as a dispersant, binder, and rheology modifier.

Good to know: Feed-grade material is subject to purity and contaminant limits relevant to animal nutrition compliance.

Commercial specifications

• Dry grades standardized to specific lignosulfonate content and moisture levels
• Bulk quantities in bags, supersacks, and liquid tanker shipments
