Cologne Storage: Bathroom Or Not?

Keeping cologne in the bathroom is a common practice, but is it the best place for it? The answer is a little more complicated than a simple yes or no. While the bathroom is convenient for a quick spritz as you get ready, it may not be the best place for long-term storage. The humidity and temperature fluctuations from showers or baths can cause issues for cologne, especially more delicate fragrances with citrus or floral notes. However, if your bathroom is well-ventilated, cool, and dark, it may not be an issue. So, what's the best way to store cologne to keep it in top condition?

Heat and light exposure

The constant temperature fluctuations in a bathroom—from hot showers to a cool post-shower environment—can massively affect the composition of cologne. The ideal storage temperature for cologne is room temperature, and removing cologne from a fridge (where some people store it for longevity) to use it and then replacing it can destroy the cologne. While a cool environment is best, anything that is significantly colder than room temperature puts stress on the cologne.

If you are storing cologne in a bathroom, ensure that it is kept away from heat sources such as radiators and hair dryers, and that the room is well-ventilated.

Humidity

However, it is important to note that not all humidity is created equal. The humidity that occurs during a brief shower or bath may not be an issue if the cologne is stored in a sealed bottle. As one source explains, "Humidity isn't really going to be a factor. It's definitely not going to be an issue if your fragrances are in spray bottles and not splash bottles. If a bottle is sealed poorly enough for humid air to get in, you'll have issues, but those issues are going to be more from oxygen and fragrance evaporation than from humidity."

Additionally, the frequency and duration of showers or baths can make a difference. A short, 10-minute shower may not cause significant humidity fluctuations that would impact the cologne. On the other hand, longer or more frequent exposures to steam and moisture could be detrimental. As one fragrance expert explains, "If a fragrance is stored in a place where the temperature changes a lot, this can cause the fragrance to sweat, with condensation getting into the fragrance and causing unwanted chemical reactions to occur. This can result in your favourite scent being ruined."

Therefore, while humidity is a concern when storing cologne, the level of humidity, the duration of exposure, and the quality of the bottle sealing all play a role in determining the potential impact on the fragrance.

Temperature fluctuations

However, cold temperatures can also impact the longevity of a fragrance. If a perfume is kept too cold for too long, the scent won't project as far or for as long, so you'll need to spray more to keep the scent lasting.

The fluctuating temperatures typical of a bathroom can cause issues for cologne. If a fragrance is stored where the temperature changes a lot, this can cause the fragrance to sweat, with condensation getting into the fragrance and causing unwanted chemical reactions. This can ruin your favourite scent.

While storing cologne in a refrigerator might seem like a good idea, this can be just as bad for the fragrance as storing it in a bathroom. The constant temperature fluctuations from removing the cologne from the fridge to use it and then replacing it can destroy the perfume.

Oxygen exposure

Excessive oxygen exposure can lead to oxidation, which can alter the scent and cause it to smell "off" or change colour. This is particularly true for delicate ingredients such as citruses and florals. Additionally, when a fragrance turns, it can smell completely different from how it did at the time of purchase due to the breakdown of fragrance oils, essential oils, and alcohols.

To minimize oxygen exposure, it is crucial to keep the bottle sealed and protected from air and humidity. Storing cologne in a cool, dry, and dark place can also help slow down the breakdown process and maintain the effectiveness of the fragrance.

It is worth noting that while some sources suggest that the bathroom may not be the ideal place to store cologne due to temperature and humidity fluctuations, others argue that it depends on the ventilation and temperature of the specific bathroom. However, to ensure the longevity of the fragrance, it is generally recommended to store cologne away from the bathroom, in a cool, dark, and dry location such as a closet, cabinet, or bedroom drawer.

Shaking the bottle

Shaking a bottle of cologne is generally not recommended. While it may not ruin the fragrance, shaking can accelerate its breakdown by incorporating air throughout the perfume. Shaking can also lead to the breakage of delicate glass bottles. However, some people believe that shaking their cologne bottle is normal, especially if it has been sitting for a while.

It is a myth that perfume must be shaken before application to ensure that the ingredients are properly mixed. In reality, perfumes are designed to remain evenly mixed if stored properly. Shaking a perfume bottle can introduce air into the bottle, which may speed up oxidation and cause the fragrance to deteriorate over time. This is different from the minor effects of temperature fluctuations during transport or the small amount of air introduced when spraying the perfume.

Additionally, shaking a cologne bottle can be risky as the friction generated during shaking may negatively impact the molecules in the fragrance. However, some people argue that molecules are always in motion, and shaking a bottle is not enough to cause significant damage.

Overall, while shaking a cologne bottle once in a while may not cause any noticeable harm, it is generally not recommended as it can potentially accelerate the breakdown of the fragrance and increase the risk of bottle breakage.
