Bio-based industrial dispersant for ceramic, construction, dye, pigment and suspension systems.
Sodium Lignosulfonate Dispersant Grade is a lignin-derived anionic dispersant for water-based systems that need particle wetting, anti-settling performance and stable suspension behavior.
This grade helps reduce agglomeration, improve suspension uniformity and stabilize fine solids in industrial formulations.
It is commonly evaluated in pigment dispersions, dye systems, ceramic slurries, construction additives and other solid-liquid formulations that require practical storage stability.
Key Performance Functions
Particle Dispersion
Reduces agglomeration of fine solids in water-based systems.
Suspension Stability
Helps keep insoluble particles distributed more evenly over storage and use.
Wetting Support
Improves contact between water phase and solid surfaces during mixing.
Industrial Compatibility
Useful in ceramic, pigment, dye and construction formulations after validation.

Buyer Questions
What is sodium lignosulfonate dispersant grade used for?
It is mainly used where fine particles must stay better dispersed in water, such as pigment systems, dye formulations, ceramic slurries and selected construction blends.
Is powder or liquid grade better?
That depends on the plant process. Powder grade often suits dry storage and export packing, while liquid grade can be easier for direct dosing into water-based systems.
Can LigninCorp help choose the right grade?
Yes. LigninCorp can recommend grade format, provide the TDS and support trial discussions based on your formulation and dosing method.
