One of the most popular scents for perfume and the scent of real roses. Traditionally it is assumed that the chemical Arabs the first to have a way to find products used scent of roses. Rose oil commands a high price because it is so difficult to extract. The collection of flowers is done by hand before dawn, and the leaves are used to provide the oil and fragrance extracts the same day. It takes many pounds of rose petals to make just one gram of oil. So how is the scent of rosescreated for the use of perfumes?
There are three common methods for obtaining oil from rose petals.
Extraction solvent extraction by steam distillation, by extraction of carbon dioxide surface
In the method of extraction solvent, the rose petals in a bath or mixed with some type of solvent such as hexane. Hexane recalls the scent of roses, and some wax and pigments. A vacuum process removes the hexane, leaving a thick waxy mass, which is called in concreteThe fragrance industry. Alcohol is put through the concrete, pulling the fragrance only partially. The mixture of alcohol and then evaporated at low pressure, with the scent of pure extract of back. This is called Rose Absolute and is a yellow-yellow to deep red in color. This is the most economical method of extraction of the perfume.
Remove pink perfume by steam distillation involves large statues full of rose petals and water. The still is heated for some time, until the water vapor withRose oil evaporates from the firm and a condenser where the condensate is drained into a container. Then the water is drained from petroleum oil, leaving very concentrated. Distilled water is then run again to extract oil soluble in water or alcohol, which is still present in water. There is also a method to perform a combination of distillation, extraction of the left over water. These components are soluble in water mixed with the original oil is concentrated to obtain oil lastProduct called Rose Otto or Attar. Rose Otto by about 20% of oil and 80% of the concentrated water-soluble products. E 'therefore much diluted when used in perfumes. E 'pale yellow to olive green in color and crystallizes at room temperature. Bulgaria is the largest producer of Rose Otto.
Method of extraction of carbon dioxide is the most expensive of three and the price of your perfume may reflect this. Carbon dioxide, which normally is a gas under normal conditionsContact pressure under pressure until it liquefies. The rose leaves are heated and mixed with liquid carbon dioxide at very low temperatures. The rest of the procedure is comparable to the standard method of solvent extraction. Normal pressure for carbon dioxide, which retracts into gas and leaves behind the flavor extracts restored. The CO2 does not leave your scent behind.
Following a good part of the quality control of the process of preparation and my pure rose oil, since notare unusual because unscrupulous diluted with essential oils of geranium flower or plant Palmarosa (based on the geranium), or other alcohol-related chemicals.
