Where Immortelle Comes From — Origin & Extraction
Immortelle is primarily sourced from the Mediterranean basin, with key producing countries including France (notably Corsica), Italy (especially Tuscany), and Portugal. The plant, Helichrysum italicum, thrives in sun-drenched, rocky, and sandy soils, often found in wild maquis landscapes. Corsican immortelle is prized for its intense, sweet aromatic profile, while Italian varieties contribute a richer, herbaceous complexity, and Portuguese origins offer a vibrant, citrusy facet.
Extraction methods vary: Immortelle absolute is obtained through solvent extraction of dried flowers, typically using volatile solvents like hexane or ethanol, yielding a viscous, dark brown paste rich in caramel, tobacco, and honey notes. Essential oil is produced via steam distillation of fresh flowering tops, resulting in a lighter, fresher aroma with more pronounced hay and clove facets. Solvent extraction preserves heavier molecules such as beta-diketones, which contribute to the absolute's depth and longevity.
Natural immortelle absolute costs approximately $3,000–6,000 per kilogram, reflecting its labor-intensive harvest and extraction. Synthetic analogues, based on molecules like safranal, cost significantly less ($50–200/kg) but lack the full complexity of the natural extract. Sustainability efforts focus on wild harvesting management and cultivation to prevent overexploitation, with Corsican producers pioneering sustainable harvest techniques.
Famous Fragrances That Define Immortelle in Perfumery
Immortelle has been a defining note in several landmark fragrances, often used to impart warmth, complexity, and a nostalgic aura. Annick Goutal's Sables (1985), crafted by perfumer Isabelle Doyen, is a seminal immortelle fragrance where the note forms a sun-baked, honeyed heart, paired with amber and woody accords. Etat Libre d'Orange's Like This (2010), by Mathilde Bijaoui, uses immortelle to evoke Thanksgiving desserts, blending it with ginger and pumpkin for a rich, gourmand effect.
Marc-Antoine Barrois' Ganymede (2019) and its Extrait (2023) showcase immortelle's versatility, pairing it with Italian mandarin, saffron, and violet to create a transparent yet textured scent. Manos Gerakinis Immortelle (2017) highlights the note's burnt brown sugar and cinnamon facets, combined with vanilla and tobacco for a gourmand warmth.
Other notable uses include Guerlain's Cuir Béluga, Kilian's Old Fashioned, and Amouage's Interlude Woman, where immortelle acts as a bridge between spicy, woody, and amber notes. CA Perfume's collection draws inspiration from this lineage, exploring immortelle's multifaceted character in contemporary compositions.
Natural vs Synthetic Immortelle in Perfumery
Natural immortelle absolute (INCI: Helichrysum italicum extract) is a complex, variable material extracted mainly by solvent methods, containing key aroma compounds such as beta-diketones, sesquiterpenes, and phenols. It offers a rich, warm, honeyed, and herbaceous scent with facets of caramel, tobacco, and spicy curry. Its longevity on smelling strips exceeds 170 hours, making it a powerful base note and fixative in gourmand, oriental, and amber compositions.
Synthetic substitutes focus on molecules like safranal (CAS 116-26-7) and analogues that replicate immortelle's spicy and honeyed facets. These synthetics provide consistent, stable aroma profiles at a fraction of the cost ($50–200/kg) compared to natural absolute ($3,000–6,000/kg). However, synthetics lack the full olfactory complexity and tenacity of natural extracts.
Famous fragrances such as Annick Goutal's Sables and Guerlain's L'Heure Bleue utilize natural immortelle absolute, while some modern niche perfumes may incorporate synthetic molecules for cost or stability reasons. The HumanSafe™ platform ensures transparency and safety data for both natural and synthetic ingredients, guiding formulators in responsible use and consumer safety.
