Disodium sebacate

Disodium sebacate (CAS 17265-14-4), also known as sodium sebacate, is the disodium salt of sebacic acid; used primarily as a corrosion inhibitor and lubrication additive in industrial fluid systems.

Where is Disodium sebacate used?

• Metalworking fluids and cutting oils: protects ferrous and non-ferrous metal surfaces during machining, extending tool and workpiece service life
• Automotive coolant and antifreeze: carboxylate-based corrosion inhibitor protecting aluminum, steel and cast iron engine components
• Oil and gas: water-based drilling fluids and pipeline treatment formulations, especially under high-salinity or high-temperature conditions
• Industrial lubricants: functional additive in rust-preventive coatings and hydraulic fluid concentrates
• In aqueous environments it provides metal surface protection where long-term equipment integrity is a priority.

Commercial specifications

• Purity typically 98% and above
• 25 kg bags or fiber drums; bulk quantities available
