How long is the shelf life of perfume after opening

Many women prefer to use some perfume in their lives, because perfume can not only bring people some fragrance, but also can dispel odor, especially the clothes in the closet, if they are not often taken out to dry, there will be some musty smell. At this time, adding some perfume fragrance can effectively remove the musty smell. However, perfume is generally easy to evaporate after opening. So how long is the shelf life of perfume after opening?

1. Does perfume have a shelf life?

I can tell you clearly that perfume does not have a fixed shelf life.

Even if the manufacturer/seller clearly states the shelf life or recommended usage period, whether the perfume deteriorates or not has nothing to do with this date. What matters is the storage environment - if it is well stored, it can still smell good after 10 years; if the storage environment is poor, it will still deteriorate even within the so-called shelf life.

2. If there is no fixed shelf life, why are the production date or expiration date marked on the products sold in domestic counters?

Perfumes sold in domestic counters must be affixed/printed with such labels, because this is the requirement of the health quarantine department: all cosmetics (including perfumes) sold domestically must clearly indicate the production/use period.

In foreign countries, there is no such requirement for perfume products, so perfumes purchased from foreign counters will not have such labels.

3. There is no fixed shelf life, so why are there signs like "Recommended to use up within xx months after opening" printed on the outer packaging of some perfumes?

Please note that this is only a recommendation for the use of opened perfume, not a requirement, and has nothing to do with unopened perfume.

Once the perfume is opened, it will inevitably come into contact with trace amounts of air, and the smell may change over time. Therefore, many businesses recommend that consumers use up opened perfume as soon as possible.

4. How to preserve perfume?

Taking the most common spray bottle as an example, the nozzle is intact and there is no leakage. The environment for storing perfume should be:

Keep in a cool, dry place, away from light and high temperature

In an average household, wardrobe drawers, closets, or even kitchen cabinets in the bedroom away from the heater can be used as places to store perfume.

If conditions permit, you can purchase a small refrigerator separately and adjust it to a lower temperature to store perfumes and cosmetics, but be careful not to mix them with food in a home refrigerator. The refrigerator at home where food is stored is actually very dirty and has a mixed smell, which is not conducive to the storage of perfume.

The contact area between perfume and air after opening is very small. Therefore, there is no need to consider this issue during normal use. But if you keep the bottle for a long time after opening, you should pay attention to the following: the bottle should be placed where it is not often moved, and the number of times you shake the bottle can be reduced to minimize the contact area between the perfume and the air.
