Potassium lignosulfonate

Potassium lignosulfonate (CAS 37314-65-1), also sold as potassium ligninsulfonate, is a water-soluble anionic polymer derived from sulfite pulping of wood.

Where is Potassium lignosulfonate used?

• Concrete and cement: water-reducing admixture improving workability and compressive strength without extra water
• Agriculture: dispersant and binder in wettable powder pesticides and granular fertilizers
• Leather tanning and textile dyeing: disperses tannins and dyes evenly across substrates
• Water treatment: sequestrant inhibiting scale formation and keeping mineral deposits in suspension in cooling systems
• It functions as a dispersant, plasticizer, and binder in industrial processes.

Good to know: Buyers should confirm compatibility requirements, as molecular weight distribution varies between production sources and affects performance in concrete versus agricultural applications.

Commercial specifications

• Purity and lignosulfonate content specified by dry solids content and sulfonate group density
