It is also present in wallflowers, some citrus fruits, chocolate, decomposing fruit, and feces. In perfumery, indole is known for its ability to bring intrigue and a seductive edge to a scent, providing an underlying animalic note. While some people love the sharp, animalic edge that indole provides, others find it unpleasant and headache-inducing.

What You'll Learn
Indole is a naturally occurring chemical compound
Indole has a very complex aroma, and its scent in pure form is described as extremely unpleasant, resembling mothballs, camphor, and feces. However, when diluted, indole takes on a floral note reminiscent of jasmine. It is this unique characteristic that makes indole highly valued in the fragrance industry, where it is used to create rich, narcotic, and intoxicating floral scents. Indole is also used in the food industry to create chocolate, coffee, and fruity accords in flavors, adding a natural quality to imitation flavor accords.
In addition to its use in fragrances and flavors, indole has important biological functions. It is a structural element of tryptophan-derived tryptamine alkaloids, including the neurotransmitter serotonin and the hormone melatonin. Indole also has pharmaceutical applications, with indole derivatives being studied for their carcinogenic and anticarcinogenic effects.
While indole occurs naturally, it can also be created synthetically. Synthetic indole produces a crystal-like substance that, when massively diluted, conjures up the scent of jasmine and orange blossom. This synthetic form of indole is commonly used in the fragrance industry, especially when a natural source is not feasible or sustainable. However, one challenge with synthetic indole is its interaction with aldehydes, which can cause darkening of the perfume liquid over time.

Indole is found in many essential oils and white flowers
Indole is a naturally occurring chemical compound that is found in many essential oils and white flowers. It is described as having a strong, penetrating, and complex aroma, with a musty, wet, and sharp-clean smell. In its pure form, indole is often likened to the scent of mothballs, camphor, or even rotten cabbage. However, when diluted, indole takes on a more delicate and soft character, adding a seductive and alluring quality to fragrances.
Indole is particularly prominent in white flowers, such as jasmine, tuberose, orange blossom, gardenia, and neroli. These flowers are known for their rich, narcotic, and intoxicating fragrances, with indole contributing a deep and slightly fecal tonality. Jasmine, especially the variety Jasmine Grandiflorum, is notorious for its strong indole note, with jasmine oils containing around 2.5% pure indole. The scent of blooming jasmine, with its combination of sweet, floral, and seductive notes, is a perfect example of how indole can enhance the allure of a fragrance.
In addition to white flowers, indole is also found in essential oils derived from citrus fruits, wallflowers, and some other floral sources. Ylang-ylang essential oil, for instance, contains traces of indole, as do bergamot and petitgrain oils. The presence of indole in these essential oils adds a unique character to their fragrance profiles.
While indole can enhance the allure of a fragrance, it also has some drawbacks when used in perfumery. One of its weaknesses is the aforementioned "mothball effect," which can be unpleasant when combined with certain other compounds. Additionally, indole has been known to interact with aldehydes to form a Schiff base, which can cause darkening of the perfume liquid over time. To address these issues, perfumers sometimes replace indole with alternative ingredients, such as Indolene or Indocolore, which offer similar indolic characters without the unwanted side effects.
In conclusion, indole is a powerful and versatile molecule that plays a significant role in both masculine and feminine fragrances. Its presence in essential oils and white flowers adds depth, richness, and a seductive edge to the scent profiles of these natural sources. While indole has some limitations, its ability to enhance and intensify fragrances makes it an important tool in the perfumer's palette.

Indole is described as having a complex aroma
Indole is a naturally-occurring chemical compound found in many essential oils, especially white flowers such as jasmine, orange blossom, and tuberose. It is also present in wallflowers and some citrus fruits. While jasmine contains the highest natural levels of indole, it can also be created synthetically. In its pure form, indole has a very complex aroma and is often described as extremely unpleasant, with a strong fecal character and a smell reminiscent of mothballs or camphor green. However, when diluted, it takes on a more floral note, evoking the scent of jasmine.
The complexity of indole's aroma lies in its ability to transform when diluted. In its pure form, the scent may be off-putting to some, but when diluted, it becomes more subtle and pleasant, blending seamlessly with other floral ingredients. This versatility allows perfumers to create unique and intriguing fragrances that can be both sexy and powerful.
One of the most well-known perfumes that contain indole is Calvin Klein Eternity. It has been described as one of the most indolic perfumes ever created, with its unique scent combining indole's complex aroma with other notes. The interaction of indole with other ingredients can enhance or soften its intensity, creating a range of effects from earthy and musty to floral and soft.
While indole is commonly associated with jasmine and other white flowers, it is also found in lilies and other plant life. Some plants even use the strong scent of indole to attract pollinators or deter predators. The meaning of pleasant and unpleasant is subjective, and indole's complex aroma can be perceived differently by different people.
In conclusion, indole is indeed described as having a complex aroma. This aroma can be manipulated and transformed through dilution and combination with other notes, creating a versatile and intriguing ingredient for perfumers to work with. Indole's unique characteristics contribute to its reputation as a powerful and intense molecule in the world of fragrances.

Indole is used to create chocolate, coffee, and fruity accords
Indole is a naturally-occurring chemical found in many essential oils, especially white flowers such as jasmine, orange blossom, and neroli. It is also present in wallflowers and some citrus fruits. In its pure form, indole is a crystal-like substance that smells like mothballs and has a heavy, sweet, tar-like pungency. However, when diluted, indole can take on a completely different character, becoming delicate and radiant.
In perfumery, indole is used in tiny amounts to bring a natural quality to floral accords. It is often paired with other notes such as green notes and other floral ingredients to create a radiant, sunny, and vivid effect. Fragrances like Chanel Cristalle, By Kilian Love & Tears, and L’Artisan Parfumeur La Chasse Aux Papillons use a delicate touch of indoles to achieve this effect.
Outside of fragrances, indole is used to create chocolate, coffee, and fruity accords in flavors. In food preparations, only trace amounts of indole are used, but it is essential to creating a natural quality in imitation flavor accords. For example, indole is used to create the rich, dark flavours of chocolate and coffee, as well as the sweet, juicy notes of various fruits.
The use of indole in flavours and fragrances is similar to that of animalic materials like natural civet and musk, which were commonly used in artificial flavours and fragrances decades ago. For example, raspberry was often formulated with civet to create a natural, fruity accord. However, indole is a more versatile ingredient that can be used in a wider range of applications without the ethical concerns associated with animal-derived ingredients.
