Lignin-based industrial emulsifier, protective colloid and suspension stabilizer for formulated systems.
Sodium Lignosulfonate Emulsifier Grade is a naturally derived industrial emulsifier and protective colloid used to stabilize oil-water systems, suspend fine particles and support more robust formulation behavior.
Its lignin backbone and sulfonate groups help reduce interfacial tension, protect dispersed droplets and support electrostatic and steric stabilization in complex formulations.
It is often assessed in industrial emulsions, suspension systems and water-based chemical blends that need better storage stability and fewer separation problems.
Key Performance Functions
Interfacial Activity
Helps reduce oil-water interfacial tension and improve emulsion formation.
Protective Colloid Action
Supports droplet protection and lowers coalescence risk.
Suspension Support
Helps stabilize insoluble particles and reduce settling.
Metal Ion Complexation
Can help chelate selected ions that destabilize formulations.
