The Musk Mystique: Cologne's Enduring Attraction

Musk is a class of aromatic substances commonly used as base notes in perfumery. The original musk came from a sex gland secretion from a specific species of deer, the Tibetan or Himalayan musk deer, which became endangered. The musk was extracted from a gland in the deer's abdomen and was dried and powdered, then soaked in ethanol to create a more pleasant aroma. Today, nearly all musk fragrance used in perfumery is synthetic, sometimes called white musk, to avoid harming the endangered deer. Synthetic musk is essential for fragrance diffusion and tenacity and is used to fix, blend and mould ingredients. It has a subtle, powdery, clean scent, similar to baby's skin, and is said to have aphrodisiac qualities.

History of musk in cologne

Musk, derived from the Late Greek 'moskhos', from Persian 'mushk' and Sanskrit 'muṣka' (meaning 'testicle'), was originally a substance with a strong odour obtained from the glands of male musk deer. The name originates from the belief that the deer gland resembled a scrotum.

The use of musk in perfumery dates back to the 6th century when it was brought from India by Greek explorers. It was then perfected by Arabic and Byzantine perfumers, including the famous Al-Kindi, who mentioned musk in many of his perfume recipes. The substance was highly valued for its aphrodisiac properties and was widely used by the Islamic prophet Muhammad and his companions, as well as Alexander the Great.

Musk was extensively used in perfumery until the late 19th century when economic and ethical concerns arose due to the endangerment of the musk deer. The natural musk trade is now controlled by the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), but illegal poaching and trading continue.

Today, most musk fragrance used in perfumery is synthetic, sometimes called "white musk". These synthetic musks are created using molecules responsible for the musk smell, such as Muscone, and can be divided into three major classes: aromatic nitro musks, polycyclic musk compounds, and macrocyclic musk compounds.

Synthetic musk

The creation of synthetic musks was largely driven by the need to eliminate the nitro functional group from nitro-musks due to their photochemical reactivity and instability in alkaline media. The discovery of ambroxide, a non-nitro aromatic musk, led to further research and the development of nitro-free musks, such as phantolide.

Today, synthetic musks can be divided into three major classes: aromatic nitro musks, polycyclic musk compounds, and macrocyclic musk compounds. The first two groups have broad applications in various industries, including cosmetics and detergents. However, concerns have been raised about their detection in human and environmental samples, as well as their carcinogenic properties, leading to bans or reductions in their use in many regions. On the other hand, macrocyclic musk compounds are expected to replace the other two classes due to their safer profile.

Animal musk

Musk is a class of aromatic substances commonly used as base notes in perfumery. Animal musk is the name originally given to a substance with a strong odour obtained from the glands of a musk deer. The substance has been used as a popular perfume fixative since ancient times and is one of the most expensive animal products in the world.

The musk deer, scientifically known as Moschus Moschiferus, belongs to the family Moschidae and lives in Tibet, India, Nepal, Pakistan, Afghanistan, China, Siberia, Mongolia, Manchuria, Korea and North Vietnam. The musk pod is a preputial gland in a pouch, or sac, under the skin of the abdomen of the male musk deer. The reddish-brown paste inside the musk pod is dried and turns into a black granular material called "musk grain", which is then tinctured with alcohol to create a pleasant odour.

Natural musk was used extensively in perfumery until the late 19th century when economic and ethical concerns led to the adoption of synthetic musk, which is now used almost exclusively. The organic compound primarily responsible for the characteristic odour of musk is muscone.

Today, the trade quantity of natural musk is controlled by the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), but illegal poaching and trading continue. The musk deer is now a protected species, and animal musk has been replaced by vegan-friendly synthetic and natural alternatives in modern perfume-making.

Different types of musk

Musk is a broad category of scent that can be found in many perfumes and colognes. Originally, it referred to a compound taken from the musk deer, which was then dried and soaked in ethanol to create a pleasant aroma. Nowadays, nearly all musk fragrance used in perfumery is synthetic, sometimes called "white musk".

There are dozens of types of musk, but here is a non-exhaustive list of some of the most common synthetic musks used in fragrances:

• Galaxolide: A syrup-like liquid due to it being mostly found diluted in a solvent. It has a slightly sweet and floral scent with powdery, fresh, and clean notes similar to a tumble dryer or clean bed sheets.
• A synthetic musk similar to Galaxolide: This one has added elegance, strength, and a slightly "woodier" and metallic undertone that replicates the smell of a hot iron on a freshly cleaned t-shirt.
• A synthetic musk with a soapy aroma: This musk also has fruity undertones and finely replicates ambrette seed oil from the musk mallow plant.
• A synthetic musk with hints of vanilla: This variety also has notes of woods and spices. It is great for intensifying other sweet and floral ingredients.

In addition to synthetic musks, there are also plant-based musks that are derived from botanical roots and seeds. Some examples include:

• Essential oils from angelica archangelica: Commonly known as garden angelica or wild celery, these plants produce a fresh, musk-like aroma.
• Abelmoschus moschatus: Also known as the musk mallow plant, this plant flourishes in the tropical climates of Asia. The oil obtained from its seeds has a heavy, sweet scent.
• Mimulus moschatus: A species of monkeyflower, otherwise known as the musk flower, that grows in the mountains and woodlands of North America. Its small yellow flowers produce a slightly musky scent.

How musk is extracted

Musk is a class of aromatic substances commonly used as base notes in perfumery. The name originates from the Late Greek 'moskhos', from Persian 'mushk' and Sanskrit 'muṣka' (lit. 'testicle'), derived from the Proto-Indo-European noun 'múh₂s' meaning "mouse". The musk deer gland was thought to resemble a scrotum.

Natural musk is obtained from the musk pod, a preputial gland in a pouch, or sac, under the skin of the abdomen of the male musk deer. The musk pod is normally obtained by killing the male deer through traps laid in the wild. The reddish-brown paste inside the musk pod is then dried and turns into a black granular material called "musk grain". This is then tinctured with alcohol to create a pleasant-smelling aroma.

The organic compound primarily responsible for the characteristic odour of musk is muscone. There are several ways of preparing commercial musk, and the best method is to dry the pod by sunning and airing immediately after it is taken from the animal. Natural musk is usually packed in hermetically sealed vessels and wooden boxes lined with tin foil because of its powerful diffusion of odour.

Today, nearly all musk fragrance used in perfumery is synthetic, sometimes called "white musk". This is due to ethical concerns and the fact that the musk deer is an endangered species. Synthetic musk can be divided into three major classes: aromatic nitro musks, polycyclic musk compounds, and macrocyclic musk compounds.
