Isononyl Isononanoate

Isononyl Isononanoate is a synthetic branched-chain ester created from isononyl alcohol and isononanoic acid, both featuring highly branched molecular structures. This double-branched architecture gives it exceptional spreading properties and an unusually dry, non-greasy skin feel compared to linear esters, making it particularly valued in sunscreens, color cosmetics, and lightweight facial moisturizers. Its branched structure also provides excellent oxidative stability and resistance to hydrolysis, contributing to longer product shelf life.
