How long can perfume be stored? Can perfume be stored in the refrigerator?

Many people like perfume, but how long can perfume be kept? Can perfume be placed in the refrigerator? What is perfume made of?

Perfume has a relatively long shelf life, and there is no definite statement. If it is not opened, it can be kept for 3-5 years at most, and if it is properly stored, it can even be kept for more than 10 years. There is no regulation on the shelf life of perfume after opening, but it is best to use it up within one year. The main ingredient of perfume is alcohol, which is volatile and will cause the fragrance to fade over time.

Perfume can be stored in the refrigerator. In summer, storing perfume in the refrigerator will have a cooling effect when spraying. Perfume can also be stored longer at low temperatures and can be used longer. Perfume should be stored away from light and kept in a dark and cool place. Light can easily change the color of perfume, especially direct sunlight, which can cause fading, discoloration, and even turbidity. Perfume should be protected from oxidation. Perfume may polymerize into a resin due to oxidation, so try to avoid contact with air. Do not leave residual liquid at the mouth of the bottle to prevent oxides from entering the bottle when used next time, causing the perfume to oxidize and deteriorate.

Perfume is made from essence, ethanol, water and other raw materials. Essence includes a mixture of natural essence (such as plant essential oils, animal spices) and synthetic monomer spices. If plant essential oils are used, the aromatic volatile oils in the plants are usually extracted by steam distillation, and then mixed with ethanol, water and other raw materials to make perfume. The spices used in perfume are generally a mixture of various spices made by perfumery.

Perfume can be brought on high-speed trains. Perfume is not a dangerous item and can be brought on high-speed trains. However, since perfume contains a certain amount of alcohol, you must comply with the high-speed train's limited carry-on rules and can only carry no more than 100ml of perfume.
