What is Isononyl acetate?
Isononyl acetate (CAS 40379-24-6), also known as 3,5,5-trimethylhexyl acetate, is an ester-based solvent and plasticizer.
Where is Isononyl acetate used?
- Coatings and printing inks: coalescing solvent and viscosity modifier supporting film formation
- Adhesives and sealants: plasticizing agent improving flexibility and substrate adhesion
- Personal care: carrier and emollient solvent
- Packaging: supports ink compatibility and regulates solvent release during high-speed printing
- It combines slow evaporation with good solvency.
Good to know: Cosmetic-grade material is available where formulation documentation and supplier quality standards are a procurement consideration.
Commercial specifications
- Purity specifications commonly at 99% or above
- Clear liquid, typically in drum and IBC quantities
