  2. Rose oil - Wikipedia

    en.wikipedia.org/wiki/Rose_oil

    There are three main methods of extracting the oil from the plant material: Steam distillation, which produces an essential oil called rose otto or attar of roses. Solvent extraction, which results in an absolute called rose absolute. Supercritical carbon dioxide extraction, yielding a concrete that may be marketed as a concrete, absolute or CO ...

  3. Fragrance extraction - Wikipedia

    en.wikipedia.org/wiki/Fragrance_extraction

    Fragrance extraction refers to the separation process of aromatic compounds from raw materials, using methods such as distillation, solvent extraction, expression, sieving, or enfleurage. [1] The results of the extracts are either essential oils , absolutes , concretes , or butters , depending on the amount of waxes in the extracted product.

    Calamodin oil or calamansi essential oil comes from a citrus tree in the Philippines extracted via cold press or steam distillation. Calamus oil Used in perfumery and formerly as a food additive; Camphor oil used in cosmetics and household cleaners. [4] Cannabis flower essential oil, used as a flavoring in foods, primarily candy and beverages ...

  5. Essential oil - Wikipedia

    en.wikipedia.org/wiki/Essential_oil

    An essential oil is a concentrated hydrophobic liquid containing volatile (easily evaporated at normal temperatures) chemical compounds from plants.Essential oils are also known as volatile oils, ethereal oils, aetheroleum, or simply as the oil of the plant from which they were extracted, such as oil of clove.

  6. Absolute (perfumery) - Wikipedia

    en.wikipedia.org/wiki/Absolute_(perfumery)

    The ethanol extract is cooled (e.g., to −15 °C) to solidify waxes, and cold filtered to yield a liquid extract. When the ethanol evaporates, an oil—the absolute—is left behind. [1] Traditionally, the absolute was obtained by enfleurage, where the resulting pommade was extracted with ethanol to yield the absolute.

  7. Concrete (perfumery) - Wikipedia

    en.wikipedia.org/wiki/Concrete_(perfumery)

    Rose is one of the most popular natural flowers used in perfumery. A semi-solid residue of essential oils, waxes, resins and other oil-soluble plant chemicals remains. [2] The solvent used for extraction must be chosen carefully regarding its polarity and boiling point. If the boiling point is too high, compounds that are readily deactivated by ...

  8. Types of plant oils - Wikipedia

    en.wikipedia.org/wiki/Types_of_plant_oils

    In modern vegetable oil production, oils are usually extracted chemically, using a solvent such as hexane. Chemical extraction is cheaper and more efficient than mechanical extraction, at a large scale, leaving only 0.5–0.7% of the oil in the plant solids, as compared to 6–14% for mechanical extraction. [4]

  9. Cananga odorata - Wikipedia

    en.wikipedia.org/wiki/Cananga_odorata

    The essential oil of the flower is obtained through steam distillation of the flowers and separated into different grades (extra, 1, 2, or 3) according to when the distillates are obtained. The main aromatic components of ylang-ylang oil are benzyl acetate, linalool, p-cresyl methyl ether, and methyl benzoate, responsible for its characteristic ...
