Calcium dinonylnaphthalenesulfonate

Calcium dinonylnaphthalenesulfonate (CAS 57855-77-3), also known as dinonylnaphthalenesulfonic acid calcium salt, is an oil-soluble calcium sulfonate.

Where is Calcium dinonylnaphthalenesulfonate used?

• Rust-preventive oils and corrosion-inhibiting coatings: forms a tenacious protective film on metal surfaces
• Metalworking fluids: stabilizes oil-in-water and water-in-oil emulsions
• Automotive and industrial gear oils: detergent-dispersant that keeps contaminants suspended and prevents deposit formation
• Oilfield drilling fluids and pipeline treatment products: used where water contamination is a concern
• It delivers corrosion inhibition, emulsification, and dispersancy in demanding industrial environments.

Commercial specifications

• Viscous liquid or dissolved in hydrocarbon solvent carriers
• Specifications defined by total base number (TBN), sulfonate content, and viscosity
• Packaging: drums to IBC totes
