Esercizio 2

For the first step, natural ingredients such as flowers, fruit and wood are harvested from around the world. Alcohol, petrochemicals and other chemical substances are also used in the manufacture of perfumes. Not every plant contains essential oil; oils aren’t produced naturally by, for example, lily of the valley flowers.

In the next step, the oil is extracted. This is done immediately after picking. Solvent extractions is a common method. To extract oil from roses, layers of petals are placed on a metal-layered drum. The flowers are then immersed in a solvents. The result of this process is a waxy material that contains the oil, which is then washed in ethyl alcohol. The oil is dissolved in the alcohol and rises. Other extraction methods include steam distillation, enfleurage and maceration. A huge number of plants are needed to get a small amount of essential oil. Approximately 200,000 rose flowers, that is 400 kilograms of flowers are required to make 600 grams of essential oil.

Once essential oil is ready, it is blended together according to a certain formula and then it is mixed with alcohol. It may takes as many as 800 different ingredients and several years to develop the special formula for a scent. In the last step of the process, the perfume is aged for several months or even years after it is blended
