Isononyl alcohol

Isononyl alcohol (CAS 27458-94-2), also known as Isononanol, is a branched-chain fatty alcohol used as a chemical intermediate and functional solvent.

Where is Isononyl alcohol used?

• Plasticizers: precursor in synthesis, including diisononyl phthalate (DINP) and phthalate-free plasticizers compounded into flexible PVC for cables and flooring
• Coatings and printing inks: slow-evaporating solvent that aids film formation and reduces viscosity
• Adhesives and sealants: reactive diluent or processing aid improving workability and substrate wetting
• Personal care: emollient carrier in skin-conditioning formulations
• It also serves as a processing solvent where controlled solvency and low volatility are required.

Good to know: Technical grade is the standard commercial specification; food-contact and cosmetic-grade material is available from select producers where downstream application compliance requires tighter quality documentation.

Commercial specifications

• Purity typically 99% or above
• Clear liquid in drum, IBC, and bulk tanker quantities
