The maximum used and economically critical technique for extracting aromatics within the current perfume enterprise. Raw materials are submerged in a solvent which can dissolve the desired fragrant compounds. Maceration lasts everywhere from hours to months. Fragrant compounds for woody and fibrous plant materials are often received on this way as are all aromatics from animal resources. The approach can also be used to extract odorants that are too risky for distillation or effortlessly denatured with the aid of warmth. Commonly used solvents for maceration/solvent extraction include ethane, hexane, and dimethyl ether. The made from this procedure is called a "concrete."

• Supercritical fluid extraction: A quite new technique for extracting aromatic compounds from a raw cloth, which frequently employs Supercritical CO2. Due to the low warmth of method and the fairly nonreactive solvent used in the extraction, the fragrant compounds derived often carefully resemble the unique scent of the uncooked material.

• Ethanol extraction: A form of solvent extraction used to extract fragrant compounds without delay from dry raw materials, in addition to the impure oily compounds materials due to solvent extraction or enfleurage. Ethanol extraction from fresh plant substances contain huge quantities of water, in an effort to additionally be extracted into the ethanol.
