Diluting Cologne: Mixing With Water, Safe Or Not?

Mixing cologne with water is not recommended as it can introduce bacteria and contaminants into the mixture. While it may seem like a good idea to stretch out your cologne by adding water, it will likely weaken the performance and longevity of the cologne. Additionally, water can cloud the fragrance and make it susceptible to bacterial growth. Instead of adding water, you can try using perfumers' alcohol or grain alcohol to dilute your cologne without affecting its performance.

Can you mix cologne with water?

Adding water to cologne may introduce bacteria

While it may be tempting to add water to your cologne to stretch it out, doing so may introduce bacteria and other contaminants into your perfume. Cologne is a mixture of essential oils, a blend of extracts, alcohol, and water. The typical concentration of cologne is 2-5% scented formulations, with a base of 70-90% dilute ethanol.

The introduction of bacteria can occur when water is not sterile and can cause the cologne to spoil or become unsafe to use. Even sterile water can become a breeding ground for bacteria once it comes into contact with the other ingredients in cologne, as it provides a hospitable environment for bacterial growth.

To avoid introducing bacteria, it is recommended to use perfumer's alcohol or grain alcohol instead of water for dilution. These types of alcohol are more effective at preserving the fragrance and preventing bacterial growth.

Additionally, adding water to cologne can weaken its performance and longevity. The water may dilute the fragrance, reducing its potency and how long it lasts on the skin.

Therefore, it is generally not recommended to add water to cologne, as it may introduce bacteria and negatively impact the fragrance's performance and longevity.

Water can dilute cologne

Diluting cologne with water is possible, but it is not recommended. While it may not hurt the notes of the cologne, it will weaken the performance and longevity of the fragrance. This is because water has the potential to introduce bacteria and contaminants into the perfume.

If you are looking to dilute your cologne, it is suggested to use perfumers alcohol or grain alcohol, instead of water.

However, water does have a purpose in perfumes and colognes. Firstly, it is cheaper than alcohol, and it is not government-regulated or taxed, which can reduce manufacturing costs. Secondly, it can improve the user experience. The presence of water can increase the persistence of odours on the skin and lessen the harsh, drying effect of alcohol. Water also retards the evaporation of alcohol, giving the top notes greater persistence, and perfumes are generally sold based on the aroma of these top notes.

Additionally, water can help to release the scent from the oil, making the perfume appear stronger to the nose. This can lead to a balancing act where less fragrance is needed to produce the desired smell strength when alcohol of a lower proof and higher water content is used. This may explain why some cheaper fragrances are preferred over more expensive originals.

In summary, while water can dilute cologne, it also has benefits and purposes in perfumery beyond simply reducing manufacturing costs.

Water may reduce the longevity of cologne

While cologne can be mixed with water, it is important to note that doing so may reduce its longevity. Adding water to cologne will dilute it, weakening its performance and reducing its staying power on the skin. This is because water has the potential to introduce bacteria and contaminants into the mixture.

When it comes to the production of cologne, the addition of water is not solely for cost reduction, despite water being cheaper than alcohol. Water can enhance the user experience by lessening the harsh, drying effects of alcohol on the skin. It also retards the evaporation of alcohol, giving the top notes greater persistence.

Furthermore, water can help release the scent from the oil, making the cologne appear stronger to the nose. This allows for the use of less fragrance to achieve the desired smell strength. However, it's important to note that water can also cloud the fragrance and make it more susceptible to bacterial growth.

Therefore, while mixing cologne with water may provide some benefits, it is important to consider the potential trade-off in terms of longevity and other possible drawbacks.

Water is cheaper than alcohol

While it is not recommended to mix cologne with water, as it can introduce bacteria and weaken the fragrance, some people still do it to stretch out their cologne. However, it is important to note that water is generally cheaper than alcohol, and this price difference has various implications.

In some countries, such as Australia, New Zealand, the Czech Republic, and Germany, alcohol is cheaper than bottled water in most bars and restaurants. This price discrepancy can have a significant impact on public health, as it may contribute to a culture of binge drinking, particularly among young people. According to research published in the New Zealand Medical Journal, the relative price of alcohol has plummeted over the past decade as average wages have increased. This makes alcohol more affordable and accessible, leading to potential health and social harm from alcohol misuse.

One of the main reasons for the low cost of alcohol in these countries is competition in the market. For example, in Australia, the wine industry has been dealing with a glut of grapes, resulting in an oversupply of wine. Additionally, the strength of the Australian currency affects wine exports. When the currency appreciates, foreign prices increase, and demand for Australian wine decreases. This leads to an excess of domestic supply, making wine even more affordable for locals.

Another factor contributing to the cheap alcohol is the pricing strategies of major retailers and supermarkets. In Australia, for instance, two retailers, Woolworths and Coles, control most alcohol sales, allowing them to negotiate lower wholesale prices with wine producers. Similarly, in the UK, leading supermarkets have been criticized for selling cut-price alcohol for less than bottled water. These retailers offer discounted own-brand alcohol, with lager costing as little as 23p per can, which is less than the equivalent volume of water.

To address the issue of cheap alcohol and its potential negative consequences, experts have suggested adopting policies similar to those used to curb tobacco consumption. This includes raising taxes, controlling marketing and sponsorship activities, and limiting the opening hours of retailers. Implementing a minimum price per unit of alcohol, especially for cask wine and alcopops, could also help curb the negative impacts of cheap alcohol on public health and society.

Water can improve the user experience of cologne

While cologne is traditionally a mixture of alcohol and essential oils, some people wonder if it is possible to add water to the mix. Some sources suggest that adding water to cologne is not beneficial and may even be harmful, as water has the potential to introduce bacteria and contaminants into the mixture.

However, others argue that water can indeed improve the user experience of cologne. Firstly, water can lessen the harsh, drying effect of alcohol on the skin, making the cologne more pleasant to use. It can also retard the evaporation of alcohol, giving the top notes greater persistence and staying power. This means that the scent of the cologne will last longer on the skin.

Additionally, water can help to release the scent from the oil, making the cologne appear stronger to the nose. This can lead to a more balanced fragrance, where less fragrance is needed to achieve the desired smell strength. This may explain why some people prefer the cheaper, more diluted colognes to their more expensive, concentrated counterparts.

Furthermore, in the process of drying, alcohol can release some unpleasant "boozy off-notes" from side products formed in traces. Water can help to reduce the presence of these unwanted scents.

In conclusion, while adding water to cologne may not be advisable for everyone, it can offer several benefits that improve the user experience, including reducing the harshness of alcohol, increasing the persistence of the scent, and enhancing the strength of the fragrance.
