Ammonium lignosulfonate

Ammonium lignosulfonate (CAS 8061-53-8), also known as Peritan NH4, is a water-soluble anionic polymer derived from sulfite pulping of wood.

Where is Ammonium lignosulfonate used?

• Concrete and cement: plasticizer and water reducer, improving workability without compromising compressive strength
• Agriculture: dispersant and binder in pesticide granules and suspension concentrates
• Water treatment: sequesters metal ions and disperses scale-forming minerals, reducing fouling
• Leather and textile processing: dispersing agent for dyes and tanning auxiliaries
• It functions as a dispersant, chelating agent, and rheology modifier.

Commercial specifications

• Brown powder or concentrated aqueous solution, typically 40% to 50% solids content
• Technical grade is the standard commercial specification
• Performance characterized by lignosulfonate content, pH, and surface tension values
• Bulk quantities in bags or supersacks; liquid tanker shipments depending on form
