Organic solvent extraction is the most common and most economically important technique for extracting aromatics in the modern perfume industry. Raw materials are submerged and agitated in a solvent that can dissolve the desired aromatic compounds. Commonly used solvents for maceration/solvent extraction include hexane, and dimethyl ether.
Perfume (UK: / ˈ p ɜː f j uː m /, US: / p ər ˈ f j uː m / ⓘ) is a mixture of fragrant essential oils or aroma compounds (fragrances), fixatives and solvents, usually in liquid form, used to give the human body, animals, food, objects, and living-spaces an agreeable scent. [1]
Fragrance bottles. An aroma compound, also known as an odorant, aroma, fragrance or flavoring, is a chemical compound that has a smell or odor.For an individual chemical or class of chemical compounds to impart a smell or fragrance, it must be sufficiently volatile for transmission via the air to the olfactory system in the upper part of the nose.
A fixative is a substance used to equalize the vapor pressures, and thus the volatilities, of the raw materials in a perfume oil, and to increase the perfume's odour tenacity. [ 1 ] [ 2 ] In simple words, fixatives increase the time for which the scent of a perfume lasts.

First, plant material is extracted with a hydrocarbon solvent, such as hexane, to yield concrete.The concrete is then extracted with ethanol.The ethanol extract is cooled (e.g., to −15 °C) to solidify waxes, and cold filtered to yield a liquid extract.
Absolutes are completely soluble in ethanol and can be used as perfume ingredients. In contrast to this, concretes are only partially soluble in ethanol due its composition of heavier substances. [2] Therefore, they cannot directly produce perfume without being made into an absolute first. Because of their insoluble character, they are also ...
Synthetic musks have a clean, smooth and sweet scent lacking the fecal notes of animal musks. They are used as flavorings and fixatives in cosmetics, detergents, perfumes and foods, supplying the base note of many perfume formulas. Most musk fragrance used in perfumery today is synthetic. [1]
