Disodium sebacate

Disodium sebacate (CAS 17265-14-4) is the disodium salt of sebacic acid, supplied in powder to crystalline form under trade names including IRGACOR DSS G and NS 18, and abbreviated as SA-NA. It carries no assigned E-code and is registered under EC number 241-300-3.

In metalworking fluids and industrial lubricants, disodium sebacate functions as a corrosion inhibitor by forming a protective coordination layer on ferrous and non-ferrous metal surfaces, displacing moisture and blocking anodic dissolution. It is also incorporated into water-based hydraulic fluids and oil-field process water treatments where pH-stable inhibition is required at elevated temperatures.

Disodium sebacate is available in technical grade and is subject to REACH registration requirements for supply within the EU. It is typically packaged in 25 kg bags or bulk quantities. Buyers should confirm grade specification and documentation, including safety data sheets compliant with EU Regulation 2020/878, with their supplier prior to procurement.
