  • Applications

    Gamma-ionone (CAS 79-76-5) is a key fragrance ingredient with violet–woody–fruity facets, widely used in fine fragrances, cosmetics and personal care (creams, shampoos, deodorants), as well as in cleaners and home care products to add depth and diffusion; in flavors it is applied at very low dosages to contribute or adjust berry, peach, tea, carrot, and tobacco notes in beverages, confectionery, baked goods, and tobacco flavors; in research and quality control it serves as an analytical reference and sensory standard when studying carotenoid degradation and flavor formation in foods; it can also act as an intermediate for the synthesis of ionone‑derived aroma molecules (e.g., damascones/damascenones) for fragrance–flavor use, with usage aligned to IFRA safety guidance, FEMA/GRAS status, and local regulations.
