Agarwood absolute is a highly valued essential oil derived from the heartwood of the Aquilaria tree, primarily through a solvent extraction process. This process is favoured for its ability to capture the complex aroma profile of agarwood more effectively than steam distillation.Solvent Extraction Process1. Harvesting: The process begins with the careful selection and harvesting of agarwood trees. The wood must be infected by a specific mold to develop the desired aromatic properties.2. Preparation: The harvested wood is typically cut into small chips to increase the surface area, facilitating better extraction.3. Extraction:o Solvent Selection: A non-polar solvent (like hexane or ethanol) is chosen to dissolve the aromatic compounds.o Maceration: The wood chips are soaked in the solvent for a specified period. This allows the essential oils and other volatile compounds to dissolve into the solvent.o Filtration: After maceration, the mixture is filtered to remove the solid wood pieces, leaving a solution of solvent and dissolved compounds.4. Evaporation: The solvent is then evaporated under reduced pressure or gentle heat, leaving behind a thick, viscous liquid—agarwood absolute. This liquid is rich in aromatic compounds and retains the complex scent profile of agarwood.5. Refinement: The absolute may undergo further refining to enhance purity and remove any residual solvents.Characteristics of Agarwood AbsoluteAroma: Agarwood absolute is known for its deep, rich, woody scent with sweet, balsamic undertones.Uses: It is widely used in perfumery, incense, and aromatherapy. It’s also valued in traditional medicine in some cultures.Color: Typically dark brown to black in color, depending on the extraction method and the age of the wood used.ConsiderationsSustainability: Agarwood is considered endangered due to overharvesting. Sustainable sourcing and cultivation practices are essential to protect these trees.Quality Variations: The quality of agarwood absolute can vary significantly based on the source of the wood, the extraction process, and the skill of the extractor.Agarwood absolute is a luxurious ingredient that offers unique olfactory experiences, making it a prized possession in the fragrance industry.
