Calcium dinonylnaphthalenesulfonate

Calcium dinonylnaphthalenesulfonate (CAS 57855-77-3), commercially recognized as dinonylnaphthalenesulfonic acid calcium salt, is an oil-soluble calcium sulfonate used across lubricant and metalworking fluid formulations.

It delivers corrosion inhibition, emulsification, and dispersancy in demanding industrial environments. In rust-preventive oils and corrosion-inhibiting coatings, it forms a tenacious protective film on metal surfaces.

This makes it a preferred additive for temporary protection of ferrous components during storage and transit. Metalworking fluid formulators incorporate it to stabilize oil-in-water and water-in-oil emulsions.

It simultaneously protects tooling and workpieces from corrosion. In automotive and industrial gear oils, it functions as a detergent-dispersant, keeping contaminants suspended and preventing deposit formation.

This performance is maintained even under high-temperature operating conditions. Oilfield applications include use in drilling fluids and pipeline treatment products where water contamination is a concern.

Corrosive environments demand the robust metal protection this additive provides. Calcium dinonylnaphthalenesulfonate is supplied as a viscous liquid or dissolved in hydrocarbon solvent carriers.

It is available in technical grade, with product specifications typically defined by total base number (TBN), sulfonate content, and viscosity to meet specific formulator requirements.

Packaging ranges from drums to IBC totes for industrial volumes. This ensures efficient handling and integration into large-scale manufacturing processes for various chemical applications.
