Although fragrant extracts are known to the general public as the generic term "[[essential oil]]s", a more specific language is used in the fragrance industry to describe the source, purity, and technique used to obtain a particular fragrant extract.
Of these extracts, only ''absolutes'', ''essential oils'', and ''tinctures'' are directly used to formulate perfumes.
*[[Absolute (perfumery)|'''Absolute''']]: Fragrant materials that are purified from a ''pommade'' or ''concrete'' by soaking them in [[ethanol]]. By using a slightly [[hydrophilic]] compound such as ethanol, most of the fragrant compounds from the waxy source materials can be extracted without dissolving any of the fragrantless waxy molecules. Absolutes are usually found in the form of an oily liquid.
*[[Concrete (perfumery)|'''Concrete''']]: Fragrant materials that have been extracted from raw materials through ''solvent extraction'' using volatile [[hydrocarbon]]s. Concretes usually contain a large amount of wax due to the ease in which the solvents dissolve various [[hydrophobic]] compounds. As such concretes are usually further purified through distillation or ethanol based solvent extraction. Concretes are typically either waxy or resinous solids or thick oily liquids.
*'''[[Essential oil]]''': Fragrant materials that have been extracted from a source material directly through ''distillation'' or ''expression'' and obtained in the form of an oily liquid. Oils extracted through expression are sometimes called ''expression oils''.
*'''Pomade''': A fragrant mass of solid fat created from the ''[[enfleurage]]'' process, in which odorous compounds in raw materials are adsorbed into animal fats. Pommades are found in the form of an oily and sticky solid.
*'''[[Tincture]]''': Fragrant materials produced by directly soaking and infusing raw materials in [[ethanol]]. Tinctures are typically thin liquids.<ref name=Fortineau/>

Products from different extraction methods are known under different names even though their starting materials are the same. For instance, orange blossoms from ''[[Citrus aurantium]]'' that have undergone solvent extraction produces "orange blossom absolute" but that which have been steam distilled is known as "neroli oil".
