Orris absolute is a highly esteemed and luxurious ingredient derived from the roots of the iris flower, specifically Iris pallida and Iris germanica. The root undergoes a lengthy drying process, often taking up to five years, during which its initial woody and earthy aroma transforms. Orris absolute is then extracted from these aged roots through a process of steam distillation followed by solvent extraction, yielding a thick, viscous substance.
The scent profile of orris absolute is distinct and multifaceted. It is primarily floral and woody with a powdery texture, reminiscent of violets. This lends a refined, sophisticated note to perfumes. Additionally, orris absolute can have nuanced undertones that include hints of sweet raspberry, earth, and a slight metallic tinge. Its rich, complex aroma makes it a prized ingredient in the formulation of high-end and niche fragrances, where it often serves as a fixative to enhance the longevity of other scents within the perfume.
