Cologne Gone Bad: How To Know When To Toss It

Knowing if your cologne has gone bad can be tricky, especially if you haven't used it in a while. However, there are several tell-tale signs that indicate it's time to toss it out. Firstly, check if the fragrance has lost its intensity or potency. If you find yourself spraying more often than usual to achieve the same effect, it's likely that your cologne has gone bad. Secondly, take note of any changes in smell. An expired cologne may develop a sour, metallic, or ethanol-like odour, and its scent will be weaker than you're used to. Thirdly, examine the colour. Discolouration, such as darker shades or a slight hue on clear liquid, could indicate that your cologne has expired. Additionally, look out for signs of skin irritation when applying cologne. While some people may not experience any side effects, others may develop itchiness or other skin conditions. Finally, check the expiration date on the bottle or packaging, which is usually indicated by batch/barcodes or catalogue numbers.

Test the smell

Testing the smell of your cologne is a simple but effective way to determine if it has gone bad. Firstly, give the cologne a quick sniff to establish its current scent. Then, walk around for about an hour, holding your wrist close to your nose to smell the cologne on your skin. After this, give the cologne one last smell. If the scent has changed since you first sprayed it, or if it doesn't smell like it used to, it has likely expired.

The scent of a cologne can change over time, and it may develop an off-note smell. This could be sour, metallic, or ethanol-like. An out-of-date cologne will usually have a weaker scent than you are used to. To avoid an unpleasant smell on your skin, test the cologne by spraying it on a piece of paper or cloth first.

If you are unsure about the smell of your cologne, you can also check for discolouration. Has the liquid in the bottle changed colour? Has it become darker or murkier? These could be signs that your cologne has expired.

It is worth noting that colognes with heavier base notes, such as vanilla, patchouli, cedar, or sandalwood, will typically last longer than those with floral or fruity scents. Additionally, synthetic fragrances can last up to 10 years, while natural fragrances tend to have a shelf life of two to five years.

Check the colour

Checking the colour of your cologne is a great way to test its freshness. Perfumes that have gone bad tend to change colour over time, usually becoming darker or developing opacity. This is a sign that the cologne is aging.

The change in colour is often due to the evaporation of perfumes with a high concentration of alcohol, which can cause the remaining liquid to become much more concentrated in essential oils. If you notice a reduction in the volume of liquid in the bottle and you are sure you haven't been using it, this is a good sign that it is going off.

The colour change is one of the most noticeable indicators of a perfume going bad, along with changes in scent and the printed expiry date. The average bottle of perfume will only keep for about three to five years before the colour and smell change, but there are ways to make your cologne last longer.

To extend the shelf life of your cologne, it is recommended to store it in a cool, dark and stable place, such as a bedroom drawer or closet. Keeping it in its original container will also help to preserve the chemical balance and prevent acceleration of the evaporation of alcohol inside.

Look for the expiry date

Knowing whether your cologne has expired or not is important, as using expired cologne could result in skin irritation or, in the worst case, an allergic reaction. One way to know if your cologne has expired is to look for the expiry date.

Expiry dates can usually be found on the back of the cologne bottle or on the packaging it came in. They may also include batch/barcode or catalogue numbers, which indicate when and where the cologne was produced. If you can't find the expiry date, look for the PAO (period-after-opening) date, which is indicated by an "opened container" symbol and tells you how many months the cologne can be used after opening.

It's important to note that cologne that is way past its expiry date may still be usable if it has been stored properly and doesn't give off any unfamiliar scents. On the other hand, even if the cologne is within its expiry date, it may have expired if it has been exposed to harsh temperature fluctuations, humidity, or direct sunlight, which can alter its chemical structure and shorten its lifespan.

Additionally, the shelf life of cologne depends on various factors, such as the quality of its packaging, the type of bottle (spray vs screw-top), and the ingredients used. Cologne with natural ingredients tends to expire faster than synthetic fragrances, which can last up to 10 years.

In conclusion, checking the expiry date is a crucial step in determining whether your cologne has gone bad. However, it's also important to consider other factors that can affect its longevity, such as storage conditions and the type of ingredients used.

Observe any skin irritation

Skin irritation is a common issue with colognes and perfumes, and it's important to observe any skin irritation that may occur after using these products. If you experience itchiness or any other skin condition after wearing a fragrance, it could be a sign that the product has gone bad or that you have a sensitivity to one of its ingredients.

To determine if your cologne is causing skin irritation, it's recommended to perform a patch test before applying it all over your body. This involves placing a small amount of the cologne on a small area of skin, such as your inner elbow or wrist, and observing any reaction over the next 24-48 hours. If you notice redness, itching, or any other irritation in the test area, it's best to discontinue use and consult a dermatologist if symptoms persist or worsen.

In addition to performing a patch test, it's important to be mindful of the ingredients in your cologne. Certain chemicals and fragrances can be common irritants, such as those found in citrus fruits, which can cause a "Margarita sunburn" when exposed to sunlight. Other ingredients like atranol and chloratranol, commonly found in oak moss, have been associated with contact dermatitis. Preservatives and synthetic fragrances in cosmetic products can also trigger skin irritation, especially for those with sensitive skin.

It's worth noting that skin irritation from cologne can also be influenced by factors such as age, sex, and skin type. Studies have shown that females tend to have a higher exposure to scented products and are more likely to develop fragrance allergies. Additionally, individuals with sensitive skin are more prone to experiencing irritation from fragrances and should be cautious when using scented products.

If you experience skin irritation from cologne, it's recommended to opt for unscented or hypoallergenic products and to choose fragrances with natural ingredients, as they tend to have a shorter shelf life and are less likely to cause irritation.

Store it in a cool, dry place

One of the best ways to ensure your cologne lasts as long as possible is to store it in a cool, dry place. The bathroom is not ideal, as there are constant temperature fluctuations and high humidity, which can cause changes in the cologne's structure and shorten its lifespan. Instead, opt for a dark closet or cupboard, where the temperature is stable and there is no direct sunlight. The fridge is also a good option, as it maintains a stable, cool temperature.

Direct sunlight and heat sources can cause the chemical structure of your cologne to change, so it's best to keep it out of sunny areas, like a windowsill. Additionally, avoid displaying your cologne on a dresser or shelf, as this can expose it to direct sunlight and cause it to expire faster. If you do choose to display your cologne, make sure it's in its original box, which will help to filter out sunlight.

It's also important to note that the quality of the packaging can affect the shelf life of your cologne. Some colognes may last for 3 to 5 years, while others might last longer. The original box can also help protect the cologne from heat, temperature changes, and humidity.

By storing your cologne in a cool, dry place, you can help extend its lifespan and maintain its freshness and potency.
