Sodium 1-naphthalenesulfonate

Sodium 1-naphthalenesulfonate (CAS 130-14-3), also known as sodium alpha-naphthalenesulfonate, is an aromatic sulfonate salt used industrially as a dispersant and wetting agent.

Where is Sodium 1-naphthalenesulfonate used?

• Pigments, dyes and solid particles: improved distribution in aqueous and mixed-solvent systems
• Textile processing: leveling and dispersing agent for vat and disperse dyes, for uniform dye uptake on fabric
• Inks and coatings: stabilises pigment dispersions and reduces agglomeration
• Plastics and polymers: dispersion of fillers and colorants during compounding
• Leather and paper: improved wetting of fibrous substrates
• It enables more consistent penetration of treatment chemicals.

Commercial specifications

• Purity 95% to 99% for standard use
• Packaging suited to bulk industrial procurement and smaller formulation quantities
