FRAGRANCE EXTRACTION 2.0
CO2 extraction is a modern method for extracting fragrances from plant material, which is used particularly in perfumery and aromatherapy. The method uses carbon dioxide in a supercritical state. Supercritical is the state between gaseous and liquid in which the CO2 is under high pressure and at a certain temperature. The gas-like and liquid-like properties of the CO2 in this state make it a very pure, efficient and environmentally friendly solvent for the perfume industry.
Advantages of CO2 extraction
- Purity: Since no chemical solvents are used, the extracted oils are very pure and free of solvent residues.
- Efficiency: Supercritical CO2 can easily penetrate plant cells and extract the fragrances efficiently.
- Temperature-friendly: The extraction can be carried out at relatively low temperatures, which prevents the degradation of temperature-sensitive fragrance components.
- Selectivity: By adjusting pressure and temperature, the process can be adapted to specific fragrance components, enabling high selectivity.
- Environmental friendliness: CO2 is an inert, naturally occurring gas that can be returned to the cycle after use, minimizing environmental impact.
Application in Perfumery
In perfumery, CO2 extraction is used to extract essential oils and other aromatic compounds from flowers, fruits, woods and resins. The fragrances obtained through CO2 extraction are often more complex and nuanced than those obtained through traditional methods such as steam distillation or solvent extraction. This allows the creation of perfumes with an exceptional depth and a very natural scent. Thanks to this technique, perfumers can access a wider range of aromas and create innovative fragrances that capture the most subtle nuances of nature.
