Oxidation in perfumes is a natural process that occurs when the liquid comes into contact with oxygen, or as a result of exposure to natural light. This causes the perfume to darken in colour and the fragrance to change. While oxidation does not cause any harm to the skin, it can be prevented by storing perfumes in a cool, dark place, such as a cupboard, drawer, or refrigerator. Additionally, some sources suggest that maceration, a process similar to aerating wine, can be used to improve the scent of a new perfume by pumping it into the air several times and allowing it to rest.

What You'll Learn

Keep perfume in a cool, dark place
Keeping perfume in a cool, dry, and dark place is essential to preserving its scent and preventing bacteria from growing. Direct sunlight and fluctuating temperatures can break down the chemical structure of perfume, causing changes in its scent and colour. Therefore, it is recommended to store perfume in a cool, dark location like a cupboard, closet, or even a refrigerator.
The ideal storage location for perfume is a cool, dark place, such as a bedroom drawer or a cupboard. Keeping perfume in a consistent environment, away from direct sunlight and heat sources, will help to preserve the fragrance for a longer period. Avoiding extreme temperatures is crucial, as too much heat or cold can adversely affect the scent quality.
It is also important to note that bathrooms are not suitable for storing perfume due to the extreme humidity and temperature fluctuations. Instead, a closet or cupboard outside the bathroom is preferable. Additionally, keeping perfume in its original box can significantly increase its longevity. When paired with a dark storage space, this method effectively preserves the scent.
To further protect your perfume from light exposure, consider using dark glass bottles such as amber or cobalt blue. These bottles block out most of the harmful light that can degrade the fragrance compounds. Discolouration in perfume can indicate that the scent has been compromised, especially in synthetic fragrances.
Lastly, remember that oxygen is perfume's worst enemy. Always keep your perfume bottles tightly capped to prevent oxidation and evaporation. By following these simple storage guidelines, you can keep your favourite perfumes smelling fresh for years to come.

Avoid sunlight exposure
Sunlight exposure can cause perfumes to deteriorate. Ultraviolet (UV) rays from the sun can break down the chemical compounds in fragrances, leading to colour changes and a weakened scent. Therefore, it is important to avoid direct sunlight when storing your perfumes.
Keep your perfumes in a cool, dark place, such as a cupboard or a box. Avoid storing them on a windowsill or any other place where they will be exposed to sunlight. If you want to go the extra mile, you can even store your perfumes in a refrigerator, as long as they are well-sealed to avoid any unwanted odours from permeating the bottle.
Additionally, it is recommended to leave your perfumes in their original packaging or a beauty case, as this will provide extra protection from sunlight and heat. The cases are designed not only for aesthetic pleasure but also to protect the fragrance.
It is also worth noting that you should avoid heat when storing your perfumes. High temperatures can accelerate the oxidation process, causing the perfume to deteriorate faster. Therefore, it is best to keep your perfumes in a cool environment, away from any sources of heat.
By following these simple steps, you can help prolong the life of your fragrances and minimise colour and scent changes caused by sunlight exposure.

Store in its original box
Storing your perfume in its original box is one of the best ways to ensure its longevity. The original boxes are made to be airtight, protecting your perfume from harmful rays and oxidation. The cardboard may seem flimsy, but it is designed to hold the bottle and its aromatic contents.
Keeping your perfume in its original box can drastically increase the life of the scent, especially when paired with a closet or cupboard. The dark, dry environment of a cupboard or drawer is ideal for storing perfume. The back of a cabinet or drawer in your bedroom is a great place to store your perfume, especially one that you don't open often. Keeping the perfume in its box in a cool, dry place will ensure the scent remains intact.
It is best to avoid storing perfume in the bathroom. The humidity from the shower or bath can oxidize the more delicate ingredients, such as citruses and florals, and negatively impact the scent. Extreme humidity and temperature fluctuations are a perfect blend for a perfume graveyard. Instead, keep the perfume in its box, away from sunlight, and in a cool environment. If temperatures are high, it may be a good idea to store the perfume in the refrigerator.
To further protect your perfume, you can double pack it. Keep it in its original box and then place it in an airtight bag. The more opaque the bag, the better, as it will guarantee minimum oxidation levels and protect the fragrance from light.

Oxidation causes colour change
Oxidation occurs when a substance reacts with oxygen, altering its composition. In perfumes, this reaction primarily affects the organic compounds present in the scent. The aldehydes in the perfume are particularly susceptible to oxidation. As these compounds react with oxygen, they undergo chemical changes that lead to a change in colour. This transformation can range from a subtle shift to a more noticeable alteration in the fragrance's appearance.
Exposure to light can also contribute to colour change in perfumes. Ultraviolet (UV) rays from sunlight or artificial sources can accelerate the oxidation process. When a fragrance is consistently exposed to light, it may undergo more rapid changes in colour and scent compared to one stored in a dark environment. Therefore, it is recommended to store perfumes in a cool, dark place, away from direct sunlight and temperature fluctuations.
Additionally, heat can accelerate oxidation, so it is best to avoid storing perfumes in areas with high temperatures. To minimise exposure to oxygen when the perfume is not in use, it is advisable to keep the bottle tightly sealed.
While the colour change in perfumes due to oxidation may be disconcerting, it does not affect the safety or overall quality of the fragrance. The fragrance may still be used without any problems, and the slight change in colour is a testament to the complex chemistry that makes perfumes intriguing.

Oxidation is safe
Oxidation is a natural chemical process that occurs when a substance comes into contact with oxygen, causing it to degrade and change its properties. While oxidation can be detrimental to certain materials, such as metals, it is important to understand that oxidation is safe in the context of perfumes.
Perfumes are created with a combination of essential oils and alcohol, and they are susceptible to oxidation over time. This oxidation process can cause the perfume to darken in colour and may alter the fragrance. However, it is perfectly safe to continue using oxidised perfumes. The change in colour and scent does not indicate any harm to your skin or health. This natural process is simply a result of the aldehydes in the perfume becoming acidic due to exposure to oxygen and light.
To slow down the oxidation process and maintain the integrity of your perfume, proper storage is key. Keep your perfumes away from direct sunlight by storing them in a dark place, such as a cupboard or their original boxes. A cool environment is also preferable, and if temperatures are high, consider storing them in the refrigerator. Additionally, as perfumes run low, the empty space in the bottle gradually fills with oxygen, accelerating oxidation. Therefore, it is advisable to use your perfumes within a few months of opening to enjoy the fragrance as intended.
While oxidation in perfumes is safe, it is worth noting that oxidation in other contexts, such as food, can have different implications. Oxidation of certain foods can lead to nutrient loss, spoilage, and the formation of harmful bacteria or toxic compounds. However, in the case of perfumes, oxidation does not pose any health risks, and you can continue to use your perfumes confidently even after they have undergone oxidation.
In summary, oxidation in perfumes is a natural and safe process. While it may alter the colour and fragrance, it does not compromise the safety of the product. By understanding how to properly store and use your perfumes, you can prolong their quality and enjoy your favourite scents without any concerns.
