Octadecenedioic acid

Octadecenedioic acid (CAS 20701-68-2) is a long-chain unsaturated dicarboxylic acid derived from oleic acid; a bio-based alternative to conventional diacids in specialty chemical formulations.

Where is Octadecenedioic acid used?

• Personal care: rheology modifier in anhydrous systems
• Personal care: skin-feel optimization in emollient-rich lip products and skin conditioners
• Coatings: reactive building block in alkyd and polyester resins
• Adhesives and sealants: co-monomer or chain extender for polyamide and polyester-based systems
• Polymer production: specialty polyesters and polyamides targeting low-melting-point performance
• Its C18 monounsaturated backbone delivers a balance of reactivity and hydrophobicity that synthetic shorter-chain diacids cannot replicate.

Commercial specifications

• Purity specifications generally ranging from 90% to 98%+
• Packaging in kilogram-scale bags through to bulk quantities depending on supplier
