The
synthetic perfume industry was founded at the end of the 19th century. In the early days, the artificial compounds contained in natural products, such as methyl salicylate in wintergreen oil, benzaldehyde in bitter almond oil, vanillin in vanilla bean, and coumarin in black coumarin, began to be
artificial Synthetic spices and implement industrial production. Later, the emergence of ionone and nitromusk was also an important milestone in the development of
synthetic fragrances. Because the production of natural essential oils is restricted by natural conditions, coupled with the development of the organic chemical industry,
synthetic fragrances have developed rapidly since the 1950s. Some terpenoid fragrances originally derived from essential oils such as linalool, geraniol, and nerol , Citronellol, citrinal, etc. have been put into production by semi-synthetic or full-synthetic methods, with considerable output. In addition, there are a series of new fragrances that have not been found in nature, such as lily aldehyde, new lily aldehyde, pentamethyl tricyclic heterochromatic musk and so on. These kinds of spices play an important role in the blending of new-flavored flavors, and there are no less than 2,000 commonly used varieties.
