High-purity lignosulfonate dispersant and emulsifier for advanced industrial formulations.
Sodium Lignosulfonate Super Grade is a high-purity lignosulfonate with elevated active content for demanding industrial dispersing and emulsifying systems.
It is designed for customers that need stronger particle dispersion, emulsion stability and more consistent additive quality in advanced formulations.
This grade is commonly evaluated in dyes, pigments, ceramics, specialty admixtures and industrial emulsions where purity and performance control matter.
Key Performance Functions

Buyer Questions
What makes sodium lignosulfonate super grade different?
Its higher lignosulfonate content and tighter quality profile make it a better fit for advanced formulations that need stronger dispersion or emulsification consistency.
Where is super grade commonly evaluated?
Typical evaluation areas include pigments, dyes, ceramics, specialty admixtures and industrial emulsions.
Can it replace standard dispersant grade directly?
Not always. It often performs differently because of higher active content, so dosage and compatibility should be revalidated in the target formulation.
