But perfume was an expensive luxury at the time, only for upper-class women to socialize, and the fragrance company was supported and protected by the imperial court.

The synthetic fragrance industry, the natural fragrance industry, namely the essential oil industry, the blended fragrance industry and the food fragrance industry, are collectively referred to as the fragrance industry. The essential oil industry mainly deals with essential oils taken from plants. The methods of oil recovery include: steam distillation, pressing, extraction, supercritical extraction, etc. Most essential oils are used as fragrance ingredients without treatment, but sometimes the main components of essential oils are separated and used, and some are mainly used as raw materials for synthetic fragrances.

As the use of synthetic spices increases, there is a need for large quantities of raw materials that are cheap and can be secured. The raw materials used in the synthetic fragrance industry are mainly citronella oil and turpentine in terms of natural essential oils, and acetylene, acetone, and isoprene in chemical products. Progress has also been made in the development of new synthetic fragrances. It is mainly manufactured through chemical reactions such as oxidation, reduction, condensation, rearrangement, decomposition, and esterification. When refining fragrances, it is important to remove trace amounts of odorous substances contained in them, rather than simply improving the purity.

Flavors and fragrances are the products of "high, refined and new" technology that have emerged with the development of modern industry, and have been widely used in food, daily chemical, tobacco, medicine and other industries, and are closely related to people's daily life. With the rapid development of the national economy and the continuous improvement of people's living standards, traditional living consumption can no longer meet the growing consumption needs of consumers. The diversified needs of consumers have driven the growth of fast-moving consumer goods such as food, cosmetics, cigarettes, and medical treatment, which has correspondingly led to the rapid development of the flavor and fragrance industry. In 2001, the sales revenue of China's flavor and fragrance industry was only about 8.7 billion yuan, and by 2011 it had reached 47 billion yuan, an increase of 4.42 times in 11 years.

After years of rapid development, China's flavor and fragrance industry has gradually completed the transformation from small workshop production to industrial production, from product imitation to independent research and development, from imported equipment to independent design and manufacturing of professional equipment, from sensory evaluation to the use of high-precision instrument testing, from the introduction of technical personnel to the independent training of professional talents, from the collection of wild resources to the introduction of cultivation and the establishment of bases, etc., the domestic flavor and fragrance manufacturing industry has developed into a relatively complete industrial system. And a number of leading enterprises in the industry that can directly participate in the international market competition have emerged.

The huge development space of China's flavor and fragrance market has also attracted many internationally renowned flavor and fragrance manufacturers to join, and the top 10 internationally renowned flavor and fragrance manufacturers have invested in China. With the continuous entry of internationally renowned flavor and fragrance manufacturers, the domestic flavor and fragrance market has gradually formed an international competition pattern in the domestic market, and domestic flavor and fragrance companies will directly face fierce international competition.

According to the survey data of the "2013-2017 China Flavor and Fragrance Industry Development Trend and Investment Prospect Forecast Analysis Report", with the intensification of competition in the flavor and fragrance industry, mergers and acquisitions and capital operation between large flavor and fragrance enterprises are becoming more and more frequent. Because of this, a large number of excellent domestic flavor and fragrance brands have risen rapidly.
