1 Pretreatment: The raw materials used to make perfume must be pure and free of impurities, so it should be pretreated before use to ensure the high quality of the product.

2. Mixing: put the raw materials for making perfume into a 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. Aging: put the mixed perfume into a closed container with a safety valve for physical or chemical aging to make the perfume smell more mellow and fragrant. The time required for aging depends on factors such as production conditions.

4. Freezing: When the perfume meets a low temperature, it will become translucent or foggy. After that, it will not be clarified if it is heated again, and it will always be turbid. Therefore, when the perfume is frozen and filtered, there will be no foggy turbidity in the future when it encounters a low temperature environment.

5. Filtration: After aging and freezing, some insoluble substances precipitate out, which can be removed by filter press with the help of filter AIDS such as diatomite to ensure its transparency and clarity.

6. Color matching: After the filtration process, a small amount of perfume will be lost by the filter aid, so it is necessary to add color after comparing with the standard sample.

7. Inspection of finished products: compare colors with instruments, measure specific gravity and refractive index, and measure alcohol content by conventional methods.

8, bottling: when bottling, leave some gaps at the bottleneck to prevent the solution in the bottle from being heated and expanded during storage and the bottle is broken.

The main raw materials are alcohol, essence and pure water, and spices are divided into natural spices and artificial spices.

Natural raw materials are substances that are more concentrated than raw materials through physical separation from plant or animal materials, and the purer the extracted raw materials, the more expensive they are. Artificial spices, usually made from petroleum or turpentine, are obtained by chemical reaction or artificial synthesis. Because artificial spices are more economical and lower in cost than natural spices, artificial spices are more widely used.
