Perfume has no shelf life. Perfume is mainly composed of essence and ethanol. Ethanol is alcohol, which has the function of disinfection and antisepsis. The percentage of ethanol in perfume is generally 60% to 90%. Therefore, perfume has never been said not to expire. However, perfume is easy to deteriorate if not properly stored. After using perfume, tighten the lid and place it in a dark and cool place at room temperature to prevent perfume from fading.
Due to the different regulations at home and abroad, according to the requirements of China's health quarantine department, all cosmetics (including perfume) sold in China should be clearly marked with the production and use period. Therefore, the warranty period marked on the bottle body of perfume is generally 3-5 years, and the perfume after opening should be used up within 24 months or 36 months. This is the recommended service life, not required to be used up within this period of time.
If the perfume is not used for a long time, you can seal the mouth of the perfume bottle with plastic wrap and store it in the refrigerator. If it is well preserved, it will still taste good 10 years later.
