Where is Sodium methylnaphthalene sulfonate used?

• Textile processing: promotes uniform dye penetration into fiber, reducing uneven coloration in batch and continuous dyeing
• Cement and concrete admixtures: dispersant improving workability and reducing water demand
• Industrial and institutional cleaning: boosts soil release and surface wetting on hard surfaces and process equipment
• Leather and paper processing baths: incorporated by manufacturers
• It improves the distribution of solids in liquid systems.

Good to know: Purity levels and active content vary by supplier, so buyers should confirm specifications against their formulation requirements.
