Isononyl acetate

Isononyl acetate (CAS 40379-24-6 ), also known as 3,5,5-trimethylhexyl acetate, is an ester-based solvent and plasticizer used across coatings, adhesives, and personal care manufacturing. It combines slow evaporation characteristics with good solvency.

This chemical is a practical choice for formulations requiring controlled drying or film flexibility. In coatings and printing inks, it functions as a coalescing solvent and viscosity modifier, supporting film formation across a range of resin systems.

Adhesive and sealant formulators incorporate it as a plasticizing agent to improve flexibility and substrate adhesion in finished products. Personal care manufacturers use it as a carrier and emollient solvent in skin-feel formulations.

It is particularly useful where a dry, non-greasy texture is required. In packaging applications, it supports ink compatibility and helps regulate solvent release during high-speed printing processes, ensuring consistent quality.

Isononyl acetate is supplied as a clear liquid, typically in drum and IBC quantities for industrial buyers. Technical grade is the standard commercial offering, with purity specifications commonly at 99% or above.

Cosmetic-grade material is available for personal care applications where formulation documentation and supplier quality standards are a procurement consideration. This ensures compliance with various industrial and safety requirements.
