7-ISOPROPYL-5-METHYLBICYCLOOCTENE-2-CARBONITRILE.

Optional CAS 68311-05-7 / PERFUMING

A synthetic fragrance molecule with dual functionality as both a perfuming agent and potential cooling sensory enhancer. This bicyclic compound belongs to a class of ingredients that can provide refreshing sensations without traditional menthol-based cooling mechanisms.

perfuming sensory enhancer

Science

Functions primarily through olfactory pathways as a fragrance component, while structurally similar bicyclooctene derivatives interact with TRPM8 cold receptors on skin surface to generate cooling sensations independent of menthol activation.
