Steam Distillation: Distillation is the most common process of extracting an Essential Oil. Steam Distillation in particular isolates the aromatic, volatile element of the plant with the help of steam.
Cold Pressing: Cold Pressing – also called Expression – is used primarily for citrus fruits like oranges and lemons, in which the Essential Oils are obtained from tiny pockets in the fruits’ peels. Oils extracted by cold pressing are the most volatile of Essential Oils and can evaporate quickly when exposed to air. Solvent Extraction: In this method, flowers that are too delicate to be processed with heat or pressure are soaked in a solvent that extracts the flowers’ volatile elements. The solvent is then evaporated at high temperatures, leaving only the most fragrant constituents behind. This process produces what is called an "Absolute."
CO2 Extraction: The CO2 Extraction method yields a greater number of aromatic compounds than any other distillation process. In certain conditions at a low temperature, Carbon Dioxide (CO2) can be pressurized to become a liquid. This liquid then acts as a solvent and is used to extract the oil from plants. After extraction is completed, the extraction vessel is brought back to normal temperature and the CO2 rapidly converts to gas, leaving behind a high-quality oil that is free of solvents.
