The origin of perfume:
The English “Perfume” of perfume is derived from the Latin “Parfumare”, which means “penetrating smoke”. As early as 1500 BC, Cleopatra VII had already started bathing with 15 different perfumes. In her day, it was illegal not to wear perfume in public places. But the first step of the European perfume industry actually started in the 16th century. At that time, Catherine De Medici came to Paris from Italy and was about to marry the King of France.

Perfume production process:
1. Pretreatment: The raw materials for making perfume must be pure and free of impurities. Therefore, it must be pretreated before use to ensure the high quality of the product.
2. Mixing: Put the raw materials for making perfume into the designated container according to a certain proportion, stir and mix for a period of time, so that the impurities in the essence can be fully precipitated and the clarity of the finished product can be improved.
3. Ageing: Put the mixed perfume into a closed container with a safety valve for physical or chemical ageing to make the perfume more mellow and fragrant. The length of time required for aging depends on factors such as production conditions.
4. Freezing: The perfume will become translucent or misty when it encounters a lower temperature. After that, if it is heated again, it will no longer be clear, and it will remain turbid. Therefore, when the perfume undergoes the freezing filtration step, it will not appear misty and turbid when it encounters a low temperature environment in the future.
5. Filtration: Some insoluble substances precipitate out after aging and freezing. Use a filter press and filter with diatomaceous earth and other filter aids to remove it to ensure its transparency.
6. Toning: After the filtering process, a small amount of perfume will be lost by the filter aid and cause the loss of fragrance and color. Therefore, it needs to be added after color comparison with the standard sample.
7. Finished product inspection: use instruments to compare color, determine specific gravity and refractive index, and determine alcohol content by conventional methods.
8. Bottling: Leave some gaps at the neck of the bottle during bottling to prevent the solution in the bottle from being heated and expanded during storage and the bottle rupture.
