Generally, the shelf life of perfume is counted from the time of opening the bottle, but the perfume we buy in China may only see a shelf life date on the bottle, which is required by the relevant regulations of the domestic cosmetics industry. However, when buying perfume abroad, the shelf life after opening the bottle is generally marked on the bottle body, and some may also mark two shelf lives.
The basic ingredients of perfume are water, alcohol and essence. Generally, the essence content is the least, and the products with different water and alcohol contents are different. According to the speed of volatilization, alcohol is the fastest. Once alcohol is volatilized, the preservation of perfume will be very problematic for a long time. Under strong light and temperature changes, perfume will be oxidized.
Please hide in the shade.
Spray perfume is easier to store, because the design on the bottle body is sealed, while immersion perfume is more difficult to store. It is recommended to clean the bottle mouth with 75% alcohol cotton ball before sealing. Cover the bottle tightly, then seal the bottle with wax and put it in a cool place, so as to avoid the smell of perfume.
The quality of artificial perfume generally seems to be about 3-5 years, and individual perfumes will last longer. The shelf life of natural perfume is 2-3 years. It is suggested that the perfume should be used up within one year after opening, and it can be thrown away when it turns black. Or expired perfume can be put in the car or sprayed on the house.
