rosacyanthin

Rosacyanthin is a fragrance compound known for its fresh green, floral aroma used in perfumery and sourced from kewra absolute.

General Material Description

Rosacyanthin, chemically identified as beta-phenethyl ethyl ether, is a volatile ether compound characterized by a fresh, green floral aroma. It commonly manifests sensory notes reminiscent of green leaves, hyacinth, chrysanthemum, jasmine, and a subtle oily waxy texture. This compound appears primarily in natural extracts such as kewra absolute, contributing to their characteristic olfactory profiles. Rosacyanthin's stable green scent, notable for its 16-hour substantivity at full concentration, makes it a valuable material in fragrance formulations. Its chemical structure and properties are indexed under PubChem, facilitating research and quality control in aroma chemistry. Derived from natural floral sources, rosacyanthin enriches compositions with herbal, gardenia, and rose-like facets, supporting diverse scent accords.

Occurrence, Applicability & Potential Uses

Rosacyanthin naturally occurs in kewra absolute, a floral extract from the pandanus flower widely used in perfumery. Its green, herbal, and floral odor qualities enable extensive use as a fragrance agent in cosmetic and personal care products. The compound enhances notes of gardenia, jasmine, hyacinth, and rose, providing fresh and natural aroma accents. According to the IFRA (Global) Code of Practice, rosacyanthin is recommended for use in fragrance concentrates at levels up to 3%. It is not approved for flavor use. Its versatility and odor profile make it suitable for complex green floral fragrance accords and natural aromatic blends.

Physico-Chemical Properties Summary

Rosacyanthin exhibits strong green odor characteristics with significant substantivity, retaining its scent for approximately 16 hours at full concentration. The compound’s ether functional group and molecular structure contribute to its volatility and polarity, impacting evaporation rate and fragrance release. Its odor profile combines fresh green and floral notes, including hyacinth, chrysanthemum, and jasmine nuances, alongside a waxy, oily undertone. These physico-chemical properties allow rosacyanthin to function effectively as a top to middle note in perfumes. Its stability and substantivity aid in prolonging fragrance persistence, while its solvency and compatibility with other aroma chemicals support flexible formulation in complex scent compositions.

FAQ
