Sodium lignosulfonate (CAS: 8061-51-6) is a water-soluble anionic polymer derived from lignin, the natural binder in wood, recovered as a by-product of the sulfite pulping process. This brown powder functions as a versatile dispersant, binder, and emulsifier across construction, agriculture, and industrial applications. In concrete admixtures, it acts as a plasticizer and water reducer improving workability and strength development. The ceramic industry employs it as a binder and dispersant in brick, tile, and refractory production. Agriculture uses lignosulfonates as dust suppressants, pellet binders for animal feed, and as slow-release carriers for micronutrient fertilizers. Additional applications include dye dispersants, oil well drilling mud thinners, and carbon black dispersion in rubber. As a renewable, biodegradable, and cost-effective biopolymer, sodium lignosulfonate exemplifies sustainable chemistry in industrial processing.

– Concrete Admixtures: Used as a water-reducing plasticizer improving workability, strength, and durability of cement and concrete mixtures.
– Ceramic Processing: Serves as a binder and dispersant in brick, tile, and refractory manufacturing enhancing green strength and surface quality.
– Agricultural Applications: Applied as a pellet binder in animal feed, dust control agent, and chelating carrier for micronutrient fertilizers.
– Industrial Dispersion: Employed as a dispersant for dyes, pigments, and carbon black, and as a thinner in oil well drilling fluids.
