Similarities and differences between rose essential oil and rose hydrosol
Rose oil saturated dew is a kind of pure dew. It is a fresh rose essence extracted by distillation. During the distillation process, hot pressure water vapor is ejected from the jet port of the jet, using the heat of the steam and the collision force of the steam molecules The volatile organic aromatic compounds combined in the cytoplasm are separated from the cellular organic matter, and they are brought to the distillation tower along with the steam, and then to the condenser for condensation. In the traditional sense, the oil that floats on the upper layer after the oil-water separator is the essential oil, and the cooling liquid in the lower layer is pure dew. Pure dew contains a small amount of essential oils, but also contains many precious parts of flowers that are insoluble in oils. These are generally nutrients that are lacking in essential oils. Therefore, although the characteristics of pure dew are similar to essential oils, they are not exactly the same. The nature o...
