Sodium methylnaphthalene sulfonate

Sodium methylnaphthalene sulfonate (CAS 26264-58-4) is an anionic surfactant used across industrial processing and formulation as a dispersant and wetting agent. It improves the distribution of solids in liquid systems. This chemical enhances substrate penetration, making it a functional building block in both process chemicals and finished formulations. In textile processing, it promotes uniform dye penetration into fiber.

This reduces uneven coloration in batch and continuous dyeing operations. Cement and concrete admixture formulators use it as a dispersant to improve workability and reduce water demand in applications. In industrial and institutional cleaning products, it boosts soil release and surface wetting on hard surfaces and process equipment. Leather and paper manufacturers incorporate it into processing baths.

Consistent dispersion of treatment agents directly affects product quality and yield. Sodium methylnaphthalene sulfonate is supplied as a powder or as an aqueous solution for various industrial uses. Powder is the more common form for dry-blended formulations and admixture manufacturing. Technical grade is the standard commercial specification for most industrial applications and processes.

Purity levels and active content vary by supplier, so buyers should confirm specifications against their formulation requirements. This ensures the material meets the necessary performance standards.
