Naphthalene-Based Dispersants: Types, Mechanisms and Selection
Naphthalene-based dispersants are anionic materials used to help separate and stabilise solid particles in aqueous systems. The term covers more than one commercial chemistry and should not be treated as a complete product specification. In industrial and formulation markets it often refers to sulfonated naphthalene-formaldehyde condensates supplied under names such as SNF, NSF, PNS, NNO…

Dispersing Agent NNO: Chemistry, Mechanism and Qualification
Dispersing Agent NNO is a commercial name used for anionic naphthalene-sulfonate condensate dispersants supplied for dye, pigment and other particulate formulations. Buyers may also encounter descriptions such as sodium naphthalene sulfonate formaldehyde condensate, sodium methylene naphthalene sulfonate or simply NNO. Because naming conventions and grade composition vary between suppliers, the product name alone is not…

How to Qualify a Dispersant NNO Supplier in China
Buyers searching for a Dispersant NNO supplier in China should compare more than a headline purity, an undated price or a generic list of applications. NNO is a polymeric sodium naphthalene sulfonate-formaldehyde condensate, commonly identified by CAS 36290-04-7, and commercial grades can differ in inorganic salt, moisture, insoluble matter and application behaviour. Supplier qualification should…

Lignosulfonic Acid Sodium Salt: Identity, Properties and Buyer Verification
Lignosulfonic acid sodium salt, commonly called sodium lignosulfonate, is a water-soluble anionic lignin derivative supplied as a powder or liquid. It is not a single low-molecular-weight molecule with one universal formula. Commercial products are complex, polydisperse materials whose composition depends on the wood source, pulping route, recovery process, purification, concentration and final grade. This guide…

What Is Lignosulfonate? Chemistry, Types and Grade Selection
Lignosulfonates are water-soluble, anionic materials derived mainly from lignin in sulfite-pulping streams. They are not one pure molecule. Commercial products contain a distribution of sulfonated lignin fragments whose composition varies with biomass source, pulping conditions, recovery and subsequent processing. Their combination of aromatic polymer structure, sulfonate groups and other oxygen-containing functional groups allows them to…
