The Significance Of 36M On Colognes Explained

The number 36M on a cologne bottle is a period-after-opening symbol that indicates the useful lifetime of a cosmetic product after its package has been opened for the first time. The letter M stands for month and the number preceding it indicates the number of months. In this case, 36M means that the cologne will be usable for 36 months or three years after it has been opened. However, some sources suggest that cologne can last much longer than this if stored correctly, with some users reporting that their fragrances are still good after 10 or 20 years.

'36M' means 36 months

The "36M" printed on a bottle of cologne means that the cologne will be usable for 36 months, or three years, after the package has been opened for the first time. This is known as the Period-After-Opening, or PAO, and is indicated by the open-jar symbol and the number of months the product will last after opening, with "M" representing "month".

The PAO symbol is used for cosmetic products with a shelf life of at least 30 months, which is the case for most colognes and perfumes due to their high alcohol content. While the PAO indicates the length of time the product will remain unchanged and perform as described, it is generally accepted that cologne stored properly can last for several years or even decades beyond the PAO. Proper storage includes keeping the cologne in a cool, dry place away from direct light and fluctuating temperatures.

This is the period-after-opening symbol

The period-after-opening symbol, also known as the PAO symbol, is a graphic symbol that identifies the useful lifetime of a cosmetic product after its package has been opened for the first time. It is depicted by an open cosmetics pot and is accompanied by a written number of months or years. This symbol is commonly found on products such as mouthwash, lotion, and shower gel.

In the context of cologne, the PAO symbol "36M" indicates a period of thirty-six months or three years. This means that once the bottle of cologne is opened, it is recommended to be used within this timeframe to ensure the product's quality and safety. However, it is important to note that the PAO symbol is a conservative estimate, and proper storage can extend the lifespan of fragrances.

Proper storage plays a crucial role in preserving the quality of cologne. It is recommended to store fragrances in a cool, dark place, away from direct sunlight and fluctuating temperatures. Keeping them in their original boxes can also help protect them from light exposure. Additionally, ensuring that the caps are tightly closed can prevent oxidation and preserve the fragrance's integrity.

While the PAO symbol provides a guideline, the actual longevity of a cologne can vary. Some fragrances may last for decades if stored properly, while others may start to change or lose their aroma over time. The composition of the cologne, particularly the presence of natural ingredients, can also affect its durability.

In summary, the period-after-opening symbol, or PAO symbol, of "36M" on a bottle of cologne indicates a recommended period of thirty-six months after opening during which the product can be safely used. However, proper storage and other factors can influence the longevity and quality of the fragrance.

It indicates the useful lifetime of a cosmetic product

The "36M" symbol on a bottle of cologne is a period-after-opening (PAO) symbol, which indicates the useful lifetime of a cosmetic product after its package has been opened for the first time. In this case, it means that the cologne will be usable for 36 months, or three years, after being opened.

It's important to note that the PAO symbol is not an expiration date or a guarantee of quality. It is a conservative estimate by the manufacturer to ensure that the product will remain unchanged and perform as described during the indicated period. The actual lifespan of a fragrance can vary depending on its formulation, storage conditions, and other factors.

Proper storage is crucial to extending the lifespan of cologne. It is recommended to keep fragrances in a cool, dry place, away from direct light and heat sources, as well as fluctuations in temperature. Storing them in their original boxes or wrapping the bottles in foil can help protect them from light exposure.

Additionally, the type of fragrance can also impact its longevity. Citrus fragrances, for example, tend to change or lose their aroma more easily over time, while base notes like woody scents (e.g. patchouli or vetiver) tend to evolve and improve with age.

With proper storage and care, a bottle of cologne can last for many years beyond the PAO symbol's indicated timeframe. However, it is essential to monitor the fragrance for any changes in smell, colour, or performance, as some components may eventually degrade and affect the overall quality of the cologne.

The cologne will last at least 3 years if stored properly

The "36M" on a cologne bottle refers to the period after opening, indicating that the fragrance will expire and no longer perform optimally 36 months after it has been opened. However, this is not a hard-and-fast rule, and many factors influence how long a cologne will last.

Proper storage is key to extending the lifespan of your cologne. Fragrances are best kept in a cool, dry, and dark place, like a bedroom drawer or closet. Keeping them in their original boxes or containers is also beneficial, as this minimises exposure to air, which can cause the alcohol in the fragrance to evaporate more quickly, leading to a faster expiration. Additionally, avoid storing cologne in the bathroom or anywhere that experiences fluctuating temperatures and humidity.

By following these storage guidelines, your cologne will likely last for several years, if not decades. Some people even suggest that fragrances improve with age, like a fine wine, especially those with heavier base notes such as oriental scents with oud and amber.

So, if you store your cologne properly, it will certainly last beyond the suggested 36 months, and you can continue to enjoy your fragrance for years to come.

It won't spoil, but the aroma may change

The "36M" on a cologne bottle is a period-after-opening symbol, or PAO, that indicates the number of months a cosmetic product can be used after its package has been opened for the first time. In this case, 36M means that the cologne can be used for 36 months or three years after opening.

It's important to note that the PAO is not an expiration date or an indication that the cologne will spoil. Cologne is mostly alcohol, which has a long shelf life and can last for decades if stored properly. However, the aroma of the cologne may change over time.

Proper storage is crucial to maintaining the quality of cologne. It should be kept in a cool, dry place, away from direct light and sudden changes in temperature. Storing it in a dark closet, drawer, or wardrobe is ideal. The bathroom and car are not suitable storage locations due to fluctuating temperatures. Additionally, keeping cologne in its original box helps protect it from direct light.

While cologne can last for many years, some signs indicate that it has gone bad. Visible flocculations, an unpleasant rotten smell, or a significant loss of fragrance intensity are all indications that the cologne should be discarded.

In summary, while the PAO of 36M provides a guideline for optimal use, it doesn't mean that the cologne will spoil. With proper storage, it can last for many years, although the aroma may evolve and change over time.
