How Does The Nose Smell Perfume?

Nose Smell Perfume

One of the most important body organs is the nose. It is defined as a muscular and skeletal structure lying between the eyes and mouth. We can breathe and sense smell in the air with the help of a nose smell perfume. Different aromas can be experienced because of this organ. 

Aromas or fragrances are considered as the first impression that can be conveyed quietly. Adorable memories, contrasting personalities, and mood changes are related to the fragrance of a perfume. But how does the nose smell perfume? In this blog, we will know about that. 

The Way The Nose Smells Perfume

It is first necessary to understand how scents work. Also, one must know how a particular aroma spreads in the air.  Well, the perfume that we spray ejects molecules that expand or interact with the surroundings. The particles of the perfume simply float in the air. 

Our nose consists of sensitive nerves that get stimulated after interaction with these molecules. But what is the exact mechanism at the core? Are there other things involved during the process of stimulation? Yes, millions of nerve cells that make up the nerves are responsible. They get activated by perfume particles. 

These nerve cells are directly linked to the brain. When the molecules of the perfume touch these cells, the cells send raw details of the perfume. Upon receiving the details, the cells of the nerve, or neurons, determine the type of smell associated with the perfume. 

The nose is an olfactory sense. It analyzes the molecule of aroma when the molecule is at its last phase. Surprisingly, the perfume particle moves through several phases before reaching the nerve cells. The first region where these particles reach is the olfactory epithelium.

Why Molecules of perfume is sensible?

The molecules of the perfume have to achieve a level of volatility so that they expand in the air quickly. In case the particles fail to evaporate, they become insensible. Sometimes, the molecules of the perfume may not evaporate because of the very low temperature in the surroundings. 

If the perfume molecules are volatile, and if they have reached the olfactory epithelium, the next part of the nose they enter is the mucus. Mucus is a thin liquid that is associated with the immunity cells. This fluid is responsible for the protection of our body. 

When perfume particles stick to the mucus, they bond with it with the help of binding pockets. However, during this phase, the particles need to be hydrophobic. This indicates that the particles must be soluble in water. In this way, the molecules of the perfume help our brain determine the type of aroma. 

Perfume particles may reach other parts of the body through the bloodstream. This may happen if you spray a lot of perfume. The taste of perfume could reach your tongue in this case. Such a condition can make you feel uncomfortable. 

Why Do Some Perfumes Cause Allergies?

Certain perfumes can cause allergic reactions in people. Several chemicals are responsible for this. Let us explore them below. 

1. Alpha Isomethylionone

Alpha Isomethylionone is a synthetic molecule that is made from the Methyl Ionone isomer. Because of its colorless nature, perfume manufacturers include this chemical in the perfume. Alpha Isomethylionone is a strong. Thus, it has the potential to cause allergies. 

2. Anisyl Alcohol

Alcohol is often used in perfumes. A common alcoholic component that is included in a perfume is Anisyl alcohol. When Anisaldehyde (a molecule associated with methoxy and formyl group) is reduced, Anisyl alcohol is produced. This chemical reacts with the skin and causes allergies. 

3. Benzyl alcohol

Another liquid that is colorless and responsible for allergies is Benzyl alcohol. This chemical is responsible for mild aroma in perfumes. It is toxic.

4. Limonene

Limonene is an organic compound that is found in several citrus fruits. This chemical is used in medicines. However, when used in perfumes, Limonene is known to cause allergic reactions. 

5. Geraniol

Geraniol is a natural oil that is obtained from Geraniol grass. The odor of this chemical is floral and rosy. However, Geraniol can cause harm to the skin after getting added to the perfume. People who are prone to allergies must avoid using perfumes that are made of these chemicals. 

Different Fragrances, Different Emotions

Smells are responsible for invoking emotions in people. That is why manufacturers focus on the fragrances or aromas of the perfume. Every odor is matched through receptors specified by the genes themselves. Due to this reason, different individuals are drawn to different smells. 

Fragrances act as an input for the emotion to rise. Different fragrances are connected to different emotions. For example, citrus and jasmine smells are associated with positive emotions. On the other hand, burning smells are related to passion. Rosy aroma is known to invoke feelings of love. 


In this blog, we have explored how the nose smells perfume in detail. Socialization and tastes can be influenced by smells. The aromas of perfumes are specially designed to invoke certain emotions and memories. Millions of cells located in our nose are responsible for taking in details of the aroma. 

Precautions must be taken while using a perfume. The quality of the smell may deteriorate if the perfume is of low quality or reaches its expiry date. Such products must not be sniffed at all. In some cases, they may cause allergies. Taking perfume orally is dangerous. People must avoid consuming perfumes because they are made up of harmful chemicals.
