Sourcing Sodium Lignosulfonate? ChemicalDekho connects you with major producers like Borregaard and domestic paper mills. Access sustainable bio-polymers for construction and dispersion.
Sodium Lignosulfonate (CAS 8061-51-6) is a 'First Generation' water reducer. While less potent than PCE or SNF, it provides excellent workability retention and acts as a retarder in hot weather. It is also widely used as a binder in animal feed pellets, carbon black, and ceramics, and as a dispersant in pesticide formulations.
Verified listings include grades with reduced sugar content (to prevent excessive retardation) and specific pH levels.

Non-toxic, biodegradable, natural polymer. Dust may cause mild irritation. Not classified as hazardous.
It is the most economical water reducer. It also naturally slows down the setting time ('Retarder'), which is a huge benefit in hot Indian summers to prevent cold joints.
Yes, it is a byproduct of the wood pulping industry (paper making), making it a sustainable and renewable resource.
Sodium Ligno is more soluble and efficient. Calcium Ligno is cheaper but can cause precipitation issues in some chemical blends.
It has a distinct sweet, woody, or slightly burnt sugar smell typical of lignin products.
