cis‑γ‑Irone is an ionone‑family odorant emblematic of the orris/iris note, widely used in fine perfumery and cosmetics to impart powdery, violet, woody facets and enhance substantivity; it acts as a heart/base‑note modifier in orris–violet, white‑floral, woody, amber, and musky accords; thanks to good stability and fiber substantivity it is employed in personal‑care and home‑care fragrances (creams, shampoos, body washes, deodorants, detergents, softeners, candles, diffusers), including microencapsulated formats for long‑lasting scent; in R&D and QC it serves as a reference/marker to standardize iris materials, assess orris concrete/absolute quality, calibrate GC‑olfactometry, and study olfaction; in some jurisdictions it is also used at trace levels as a flavoring to deliver violet‑fruity nuances in confectionery, beverages, and chewing gum, subject to applicable safety standards (e.g., IFRA for dermal exposure) and local food regulations.
