Dodecanedioic acid

Dodecanedioic acid (CAS 693-23-2), commonly abbreviated as DDDA, is a long-chain dicarboxylic acid used as a building block in polymer synthesis and a functional acid in lubricant formulations.

Where is Dodecanedioic acid used?

• Plastics and polymers: key monomer in Nylon 6,12 and Nylon 12,12, with longer carbon chain delivering improved flexibility and lower moisture absorption than shorter-chain diacids
• Lubricants and metalworking: diester base fluids and corrosion inhibitors for biodegradable lubricant systems
• Personal care: emulsifier and texture modifier in creams and rinse-off products
• Food-contact and flavor-adjacent formulations: acidulant and processing aid
• It also serves as a surface-active agent in personal care and industrial applications.

Commercial specifications

• Purity typically 99% or higher for monomer-grade requirements
