Product Overview

Calcium Ligninsulfonate (CAS No. 8061-52-7) is the calcium salt of lignosulfonic acids, a family of sulfonated lignin-derived macromolecules obtained from lignocellulosic processing. It is a variable-composition polymeric material rather than a single uniform stoichiometric compound. Its aromatic lignin framework, sulfonate groups and other oxygen-containing functionalities give it water compatibility, surface activity, adsorption capability and polyelectrolyte behaviour.

The product is intended for formulation, dispersion, binding and materials-development work requiring a lignin-derived anionic polymer. Because no grade, molecular-mass distribution or compositional specification is stated, the description does not assign a precise structure, sulfonate content, reducing-sugar content, viscosity or performance value.

Typical Applications

• Dispersing and water-reducing component in experimental cementitious and mineral suspensions.
• Dispersant for pigments, carbonaceous materials, ceramic powders and other particulate systems.
• Binder and agglomeration aid in laboratory pellet, granule and briquette formulations.
• Rheology-modifying and suspension-stabilising component in aqueous formulations.
• Investigation of adsorption on mineral, oxide and cement-particle surfaces.
• Research on lignin-derived polyelectrolytes, renewable polymers and modified lignosulfonate materials.

Storage Conditions

Store in a tightly closed container in a cool, dry and clean area. Protect from moisture, contamination and prolonged exposure to humid air to preserve handling characteristics and minimise caking or compositional change.
