Perfumery Terms

    Term Definition
    ABSOLUTE: A highly-concentrated fragrance oil similar to essential oil, but produced through an extraction process using volatile solvents. The extracted solid material is then combined with alcohol to produce the absolute.
    ACCORD: Several perfume notes or ingredients that are combined to produce a third unique scent that smells like something else entirely.
    ANIMAL: Originally used to describe animal-derived ingredients like ambergris or musk that emit a sensual, musky smell. Today’s animal facets are usually replaced by synthetics.
    BASE NOTES: The heaviest, longest-lasting notes in a fragrance, base notes act as a foundation to enhance the scent of other ingredients. Once the heart notes have faded, they take on a character of their own, otherwise known as the “dry down.”
    CITRUS: Composed of oils from lemon, orange, bergamot, grapefruit or mandarin zest, the citrus family imparts fresh, clean, bright notes when added to the top notes of a fragrance.
    CONCRETE: A solid, waxy substance obtained from the extraction of plants using volatile solvents. Concretes are usually further rinsed with alcohol and concentrated to produce an absolute.
    CORE NOTES: Often referred to as middle or heart notes, core notes usually define the way a scent is described and categorized. They have a strong influence on the base notes that follow and often comprise a smooth floral and/or fruit tone.
    CHYPRE: A generic name for a family of fragrances with a mossy, woody base, chypre was originally inspired by the smells of the island of Cyprus: sharp patchouli and oak-moss base notes intertwined with citrus.
    DISTILLATION: An extraction method for obtaining aromatic compounds from plants by steam evaporation.
    EAU DE COLOGNE: A term used by perfume brands to refer to fragrances whose concentration usually stands between 2% and 5% fragrance oil to alcohol.

    ESSENTIAL OILS: A concentrated distillation of a fragrant plant usually extracted via steam distillation.
    EXTRACT: A general reference to a concentrated extraction from a natural source to obtain and represent the source aroma. Extracts can also be synthesized in the lab to ensure consistency and sustainability.
    FOUGÈRE: Named after the French term for fern, fougère are green and aromatic herbal scents featuring lavender, oakmoss, citrus and woods that are often used in men’s scents.
    HEADSPACE: A method pioneered in the 1970s of capturing scent molecules and reconstructing their smell. A bell-jar like apparatus is placed over the scented object to capture the odor compounds in the surrounding air. It’s then analyzed to produce a synthetic version.
    HESPERIDIC: A term used to describe the essential oils obtained from citrus fruits.
    MOLECULAR DISTILLATION: A technique used to remove colors or contaminants in essential oils and extracts that results in very pure raw materials
