The 1939 Nobel Laureate for Chemistry, Leopold Ružička stated in 1945 that "right from the earliest days of scientific chemistry up to the present time, perfumes have substantially contributed to the development of organic chemistry as regards methods, systematic classification, and theory." Ancient texts and archaeological excavations show the use of perfumes in some of the earliest human civilizations. Modern perfumery began in the late 19th century with the commercial synthesis of aroma compounds such as vanillin or coumarin, which allowed for the composition of perfumes with smells previously unattainable solely from natural aromatics.

A ''flacon'' (from Late Latin , meaning "bottle"; cf. "flagon") is a small, often decorative, bottle. It has an opening seal or stopper and is designed to hold valuable liquids which may deteriorate upon contact with the air. They are widespread in the food industry, the pharmaceutical industry, and the cosmetics industry. They are generally made of glass for perfumes, but can also be made out of plastics for other uses. Manufacturing techniques The plastic bottles can be manufactured using different processes depending on the size and the proposed application (i.e. what the content will be, what the surrounding environment will be etc.). A common technique is blow molding. Like any object made by extrusion, it is possible to produce multilayer plastic bottles. This is called coextrusion. The combination of different materials or colours can be used to produce flacons with different properties, such as: impermeability to light, oxygen, recycled inner layer. The glass bottles are m ...
