Lignosulfonates and Lignin – A Renewable, High-Performance Bio-Polymer
Our Products
Lignosulfonates (Sulfonated Lignin) are versatile, environmentally friendly co-products derived from the sulfite pulping process used in the production of dissolving pulp. During this process, Red and Black Liquors—rich in sulfonated lignin compounds—are produced. These liquors contain water-soluble anionic polyelectrolyte polymers with high molecular weight, making lignosulfonates an exceptional renewable alternative to synthetic dispersants and binders.
Legnochem supplies a full range of lignosulfonate products across North America, available in both liquid (bulk – truck and rail) and dry (bagged) forms, sourced from multiple reliable production points. Some of our products are OMRI-listed, approved for use in organic crop production, supporting the growing demand for sustainable agricultural inputs.

Versatile Applications Across Industries
Lignosulfonates combine strong binding, dispersing, and stabilizing properties making them indispensable in a wide range of industries and formulations
Agriculture & Animal Nutrition
• Effective pellet binder for pelletized limestone or gypsum, animal feed, pet food, and fertilizers
• Used in organic crop production as a biodegradable surfactant and soil conditioner
• Enhances granulation and nutrient uniformity in fertilizers
Construction Materials
• Dispersant in concrete admixtures, brick, and gypsum board production, improving workability and strength while reducing water demand
• Used in pigment, dye, and carbon black formulations for uniform dispersion and color stability
Dust Control & Road Treatment
• Functions as a natural binder and surfactant for road dust suppression, creating durable, weather-resistant surfaces
• Reduces dust emissions in mining, logging, and unpaved transportation routes
Oil & Gas Industry
• Serves as an emulsion stabilizer and fluid-loss control agent in drilling muds and oil-well additives
• Improves rheology and stability in challenging downhole environments
Industrial Manufacturing
• Used as a copolymer in phenolic resin production, enhancing polymer structure and performance
• Acts as a binder and dispersant for metal ores and ceramics, improving processing efficiency and material strength
