Lignosulfonate Binder & Dispersant
Magnesium Lignosulfonate
Magnesium lignosulfonate is a water-soluble lignin-based industrial additive used as a concrete water reducer, ceramic and refractory binder, mineral and powder binder, dust control aid, dispersant and viscosity control support in selected water-based formulations.
LigninCorp supplies magnesium lignosulfonate powder and liquid grades for manufacturers, distributors and formulation teams that need specification review, TDS/MSDS documents, sample evaluation, packaging confirmation and export quotation support.
Product Overview
Magnesium lignosulfonate, also written as magnesium lignosulphonate, is a lignosulfonate salt used where buyers need water solubility, dispersion, binding strength and compatibility with mineral, cementitious or powder-based industrial systems.
For broader lignosulfonate comparison, buyers can also review sodium lignosulfonate, calcium lignosulfonate, sodium lignosulfonate binder grade and the full industrial chemical products catalog.
Buyer note
Magnesium lignosulfonate is usually evaluated by product code, physical form, dry matter or solid content, water-insoluble matter, lignosulphonate content, total magnesium and calcium, pH, moisture, packaging and document requirements.
Main Specification
Typical values from the current technical data sheets (GAC-MgLS-1, GAC-MgLS-2 and GAC-MgLS-L, Revision 1.0). Values are typical production results for reference, not a binding specification; the COA accompanying each shipment reports batch results.

Application Fit and Grade Direction
Concrete and Cement Systems
Used as a common water reducing agent and raw material for set-retarding water reducers or pumping admixtures. Related pages: concrete admixtures, SNF superplasticizer and PCE powder.
Ceramic and Refractory Binders
Supports binding, strengthening and processing behavior in ceramic and refractory systems. See ceramic and refractory additives for application context.
Mining, Mineral and Powder Binding
Can work as a binder for iron ore powder, lead and zinc powder, pulverized coal, coke powder and selected mineral aggregate systems. Review related mineral processing and mining applications.
Dust Control and Bulk Materials
Can be evaluated for dusty industrial processes and road dust suppression where lignosulfonate binding and dispersion behavior are needed. Compare with dust suppression road stabilization.
Dispersant and Viscosity Support
Used as a dispersant or viscosity depressant in selected water-based systems, including insoluble solids or liquid-in-water dispersion needs. Compare with Dispersant NNO and Dispersant MF.
Agriculture and Pesticide Formulations
The current page links to GREEN AGROCHEM magnesium lignosulfonate for agriculture-oriented context. Confirm local regulations and formulation requirements before use.
Packaging, Documents and Export Support
Standard packing is 25 kg woven bags with inner liner. Packaging can be discussed according to customer requirement, destination market, pallet preference and container loading plan.
LigninCorp can support B2B buyers with TDS, MSDS/SDS, COA, sample dispatch, product code confirmation and quotation for distributor or manufacturer evaluation.
Technical documents
Request the current TDS, SDS and representative COA for the exact grade code before quotation or sample evaluation. Documents issued under the former single code GAC-MgLS are superseded.
Buyer Questions
When should buyers choose magnesium lignosulfonate?
Choose magnesium lignosulfonate when the target formulation needs lignosulfonate dispersion or binding behavior with magnesium as the cation profile. For many industrial systems, buyers compare magnesium, sodium and calcium lignosulfonate before final grade selection.
Can LigninCorp provide samples and technical documents?
Yes. Send target application, expected quantity, destination port and packaging requirement. LigninCorp can support TDS, MSDS/SDS, COA, samples and quotation details.
Is this page for B2B buyers or retail purchase?
This is a B2B industrial chemical product page for manufacturers, distributors and formulation teams. Pricing, availability and packaging are confirmed by inquiry instead of public retail checkout.
