Perfume is a mixture of fragrance oils, alcohol, and water. The amount of water in perfume depends on the type of perfume. For example, colognes contain about 3-5% perfume oil, 80-90% alcohol, and 5-15% water, while Eau de toilettes contain about 2-8% perfume oil, 60-80% alcohol, and the rest is water. The purpose of water in perfume is to reduce manufacturing costs as water is cheaper than alcohol and is not government-regulated or taxed. Additionally, water can lessen the harsh, drying effect of alcohol on the skin and increase the persistence of odours.

What You'll Learn
Water is added to reduce the drying effect of alcohol on skin
Water is added to perfumes to reduce the drying effect of alcohol on the skin. While the exact amount varies, perfumes typically contain about 3-20% water.
Alcohol is known to dry out the skin, particularly if it is already weakened, dry, or sensitive. According to dermatologist Dr. Diane Madfes, "Alcohol dehydrates the skin by evaporation of water and a breakdown of lipids in our skin's top layer. This causes a disruption of our epidermal carrier and increased skin sensitivity."
The addition of water helps to mitigate this drying effect. F.V. Wells, in Perfumery Technology, notes that "the presence of water... generally increases the persistence of odours on the skin." Water can also make the scent appear stronger, as it helps release the scent from the oil, while pure alcohol can hold it back. This can lead to a more pleasing fragrance, as some find that lower-proof alcohol with a higher water content produces a more acceptable scent.
Some people choose to add a few percent of water to their perfumes, as it decreases the vapour pressure of the water-alcohol mix and slows evaporation, making the perfume last longer on the skin. However, others find that adding water makes the smell less noticeable, and it can cause solubility problems with the fragrance.
Overall, the addition of water to perfumes is done to balance the drying effect of alcohol and create a more pleasant and longer-lasting fragrance.

Water makes perfume cheaper to produce
Water is often added to perfumes to reduce manufacturing costs. As the water content in perfume goes up, the price goes down. This is because water is cheaper than alcohol, and it is not government-regulated or taxed.
The use of water in perfume is not a modern phenomenon. In the past, royalty and nobility used scented waters for personal grooming. For example, the King of France, Louis XIV, used a concoction of scents called "heavenly water" to perfume his shirts. This mixture included aloewood, musk, orange flower, rose water, and other spices.
Today, water is added to perfumes to reduce the harsh, drying effect of alcohol on the skin. However, it is important to note that water can also cause solubility problems with fragrances, as most perfumery materials do not dissolve in water. Additionally, water can make the fragrance cloudy and susceptible to bacterial growth.
The amount of water added to perfumes varies, but it is typically around 10% or less by volume. Some sources suggest that adding water to perfumes can enhance the scent by increasing the persistence of odours on the skin. However, others argue that the increased scent perception is due to the agitation of the washing process rather than the presence of water.
Overall, while water can make perfume cheaper to produce, it also has an impact on the fragrance's performance and customer experience.

Water can make perfume cloudy
Water is commonly added to perfumes to reduce the harsh, drying effect of alcohol on the skin. It also makes the perfume cheaper to produce, as water is cheaper than alcohol and is not government-regulated or taxed. However, water can also cause cloudiness in perfumes.
Perfumes are typically composed of alcohol and various oils. As we know from basic science, oil and water do not mix. Therefore, any water in the alcohol will not mix with the oils in the perfume, resulting in cloudiness. The higher the percentage of water, the more pronounced this problem will be. This cloudiness can be reduced by using at least 95% ethanol or perfumer's alcohol, which is either 100% straight ethanol or very close to it.
Some people add water to their perfumes intentionally, as they believe it makes the scent last longer. F.V. Wells, in Bilot & Wells' Perfumery Technology, supports this idea, suggesting that "the presence of water... generally increases the persistence of odours on the skin". However, others disagree, arguing that it is the agitation of the washing process that causes the scent to become more pronounced.
Cloudiness in perfume can also be a sign of contamination or degradation. If a perfume is exposed to temperature extremes, for example, it may turn cloudy and give off a stale or old vibe. However, this does not necessarily indicate that the perfume has gone bad, as one person reported that a cloudy bottle of aftershave they purchased still smelled fine.
In conclusion, while water can be added to perfumes for various reasons, it is important to be aware that it may cause cloudiness and separation. To avoid this, it is recommended to use high-proof ethanol or perfumer's alcohol, which contains minimal water.

Water may increase the persistence of odours on the skin
The presence of water in perfumes is a topic that has been discussed by various sources. One common reason for the inclusion of water in perfumes is to reduce the manufacturing cost, as water is cheaper than alcohol. However, F.V. Wells, in "Perfumery Technology", suggests that water generally increases the persistence of odours on the skin. This is supported by the observation that some costly fragrances also include water.
Wells' suggestion is further validated by the consensus that adding water reduces the harsh, drying effect of alcohol on the skin. This makes the perfume more pleasant when applied to the skin. Additionally, it is proposed that water retards the evaporation of alcohol, giving the top notes greater persistence or staying power. Perfumes are typically sold based on the aroma of these top notes.
The role of water in enhancing the persistence of odours on the skin is also influenced by the ratio of water to alcohol. While a small amount of water can be beneficial, adding too much water can lead to solubility problems with the fragrance. This highlights the delicate balance that perfumers must consider when formulating their creations.
Furthermore, the introduction of atomizers in the late 19th century played a significant role in the merging of perfume and toilette water. Atomizers facilitated the creation of lighter, more water-laden fragrances that could be easily sprayed. This technological advancement resulted in perfumes gaining more water and toilette waters gaining more alcohol.
While the impact of water on the persistence of odours is a subject of discussion, it is important to note that other variables, such as the agitation of the washing process, may also influence the release of scents. Nevertheless, the presence of water in perfumes has both economic and aromatic implications, contributing to a complex understanding of this ubiquitous ingredient.

Water can be left out of the formula
Water is not an essential ingredient in perfumes. It is possible to make a fragrance without it, using only fragrance oil and alcohol.
The water content in perfumes is usually a result of the alcohol used, which typically contains some water. For example, ethanol used for perfumery is usually around 95% alcohol, with the remaining 5% being water. This is because it is very difficult to obtain purer ethanol through distillation. While it is possible to obtain purer ethanol through other means, it is very expensive and does not make a substantive difference to the final fragrance.
Some perfumers choose to add water to their fragrances, usually to reduce the harsh, drying effect of alcohol on the skin. However, this is not necessary, and some sources state that adding water to an alcohol-based fragrance will only serve to cloud the perfume and make it more susceptible to bacterial growth.
Water also has the potential to reduce manufacturing costs. As water is cheaper than alcohol and is not government-regulated or taxed, increasing the water content of a fragrance will lower its price.
Finally, some people believe that water can positively impact a perfume's fragrance. F.V. Wells, for example, suggests that "the presence of water... generally increases the persistence of odours on the skin". Water clings to the top notes of a fragrance and gives them greater persistence, or 'staying power'.
