CINNAMYL ISOBUTYRATE.

Optional CAS 103-59-3 / PERFUMING

An aromatic ester primarily utilized for its sophisticated sweet, balsamic, and fruity fragrance profile in personal care formulations. While valued for its sensory contributions, it is also being investigated for secondary potential as an antimicrobial and antioxidant agent.

Perfuming Flavoring

Science

Functioning as a perfuming agent, it interacts with the olfactory system to provide a sweet scent; on a molecular level, it may provide auxiliary formulation support through mild antimicrobial and antioxidant activities, though these are not its primary skin-active functions.
