Description

Sodium Diisododecylnaphthalenesulphonate CAS NO 63701-24-6 is a high-performance anionic surfactant derived from naphthalene. This compound matters for its excellent wetting, dispersing, and emulsifying properties in demanding formulations. It is primarily needed by manufacturers in the agrochemical, textile, and industrial cleaning sectors where robust surfactant performance is critical.

Application

• Agrochemical Formulations: Acts as a key wetting and dispersing agent in pesticide and herbicide concentrates.
• Textile Processing: Used in scouring, dyeing, and finishing operations to improve penetration and levelness.
• Industrial & Institutional (I&I) Cleaners: Serves as a powerful surfactant in heavy-duty degreasers and cleaning formulations.
• Paint & Coating Additives: Functions as a pigment dispersant and grinding aid to enhance color development and stability.
• Oilfield Chemicals: Employed in drilling muds and other formulations for its emulsifying and surface-active properties.
• Leather Processing: Aids in the wetting and penetration of chemicals during tanning and dyeing processes.
