How to store perfume? How long is the shelf life of perfume?

Perfume is a very common product on the market. Many people like to use perfume. At the same time, we all know that perfume is easy to evaporate. So let's learn about the preservation method of perfume. What is the shelf life of perfume?

Perfume should be stored in a dark place. Because perfume is volatile, you must press the bottle cap tightly to prevent the perfume from emitting. Most perfumes use high-quality essential oils, and essential oils will decompose and change when exposed to light, especially direct sunlight, which will cause the perfume to fade, change color, or even become turbid. Perfume is very sensitive to air and may be oxidized and polymerized into resin, so try to avoid perfume contact with air. Be sure to handle it with care when using it, otherwise violent shaking and friction will easily accelerate the volatilization of the perfume. The internal components of perfume will accelerate oxidation and decomposition at high temperatures. Because of this, some friends will put perfume in the refrigerator, which is also wrong, because when the temperature is too low, the perfume will precipitate crystals of the fragrance. Avoid direct sunlight when placing it, otherwise the color and fragrance of the perfume will change to a certain extent.

The shelf life of perfume is generally 3-5 years in China. Perfume is an alcohol solution of essence, plus a proper amount of spices. It has a strong and fragrant aroma. Its main function is to spray it on the lapels, handkerchiefs and hairline, etc., to emit a pleasant aroma. It is one of the important cosmetics. Perfume, essence and spices are all volatile substances; they have a certain aroma and fragrance, which can be perceived by people's sense of smell or taste; they are required to achieve the purpose of being lovable, spiritually pleasing and enriching people's material culture and life. Perfume is widely used. For example, if you sprinkle perfume on your skin, the temperature of your body will make the fragrance evaporate from your body, making you more attractive; applying perfume thinly on the roots of your ears, the inside of your elbows, and the inside of your knees will give you a hazy beauty; sprinkle a little perfume on your handkerchief and put it in your pocket, and an alluring scent will be emitted from your pocket.

1. Pretreatment: The raw materials for making perfume must be pure and free of impurities. Therefore, they must 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 in a certain proportion, stir and mix them for a period of time to allow the impurities in the fragrance to fully precipitate and improve the clarity of the finished product.

3. Aging: Put the mixed perfume into a sealed container with a safety valve for physical or chemical aging to make the perfume more mellow and fragrant. The length of aging time is determined by production conditions and other factors.

4. Freezing: When perfume is exposed to low temperatures, it will become translucent or foggy. If it is heated again, it will no longer become clear and will always be turbid. Therefore, if the perfume is frozen and filtered, it will not become foggy when it encounters a low temperature environment in the future.

5. Filtration: After aging and freezing, some insoluble substances will precipitate out. Use a filter press and filter aids such as diatomaceous earth to remove them to ensure their transparency and clarity.

6. Color adjustment: After the filtration process, a small amount of spices will be lost by the filter aids, resulting in the loss of aroma and color. Therefore, it is necessary to add color after comparing the color with the standard sample.

7. Finished product inspection: Use instruments to compare color, measure specific gravity and refractive index, and use conventional methods to determine alcohol content, etc.

8. Bottling: Leave some space at the bottleneck when bottling to prevent the solution in the bottle from expanding due to heat during storage and causing the bottle to burst.
