Fragrances are substances with strong-smelling organic compounds that have pleasant odors. Manufacturers use fragrances in a variety of products, including perfumes, colognes, aftershaves, and cosmetics. The art of perfumery has a rich history, with its roots in ancient civilizations like ancient Rome and Islamic-controlled Spain. Today, fragrances are classified based on their concentration of aromatic compounds, with terms like parfum or eau de parfum indicating the intensity and longevity of the scent. While fragrances enhance our olfactory experience, there are concerns about the potential health and environmental risks associated with certain fragrance chemicals. Some fragrance ingredients are toxic and can cause adverse health effects, while others contribute to indoor air pollution and environmental contamination.

What You'll Learn
Fragrances improve cleanliness and are used in devotion to God
Fragrances are often added to cleaning products to improve their smell and make them more appealing to consumers. Many of the chemical ingredients in cleaning products have an unpleasant odour, so fragrances are used to mask these smells. For example, synthetic musks are used to cover the unpleasant scent of laundry detergents and personal cleaning products. The use of fragrances in cleaning products is not just about improving the smell, but also about creating a perception of cleanliness. Tropical aromas, such as pine or cedar, and citrus scents are commonly associated with cleanliness and can even boost moral behaviour, according to a study by Brigham Young University.
Fragrances have a long history of being used in devotion to God, dating back to ancient times. In Islamic-controlled cities in Spain, such as Al-Andalus, fragrances were used as a layer of cleanliness that was needed for their devotion to God. The art of perfumery in Western Europe was also influenced by the Islamic invasion of Spain and Southern Italy, with recipes for perfumes recorded by monks in Italy as early as 1221.
Today, fragrances continue to play a role in religious and spiritual practices. For example, Devotion Pour Homme by Dolce & Gabbana is a men's cologne that combines citrus and coffee notes, creating a soft and sharp scent. The women's version, Devotion, celebrates the aromas of the Italian dessert panettone, with top notes of candied lemon, a heart of orange blossom, and a base of vanilla. These fragrances offer a modern take on devotion, providing a sensory experience that evokes a sense of elegance, class, and summer.
The act of applying fragrance can also be a form of devotion or self-care ritual. Taking the time to choose and wear a fragrance that aligns with one's values and aspirations can be an act of devotion to oneself and one's sense of well-being. Fragrances have the power to enhance our emotions and experiences, whether it's a feeling of cleanliness, a connection to nature, or a sense of elegance and sophistication.

They are used in courtship and socialising
Fragrances have been used in courtship and socialising for centuries. The sense of smell has a rare evocative intensity, especially on the female brain, and can be a powerful tool in the arsenal of anyone looking to attract a partner.
A study published in the Journal of Environmental Psychology in 2012 found that pleasant fragrances have a positive effect on dating requests. In the study, an attractive man approached 18-25-year-old women in a shopping mall and asked for their phone numbers. The women were approached in areas with pleasant ambient odours (e.g. pastries) or with no odour. It was found that women agreed more often to the man's request in the pleasant-smelling areas. The researchers suggested that pleasant odours tend to increase positive moods, and people in a good mood are more likely to help, trust each other, and say yes to a request.
The power of scent when it comes to attracting a partner has been recognised for centuries. Ancient texts and archaeological excavations show the use of perfumes in some of the earliest human civilisations. The art of perfumery in Western Europe was reinvigorated after the Islamic invasion of Spain and Southern Italy in the 8th and 10th centuries, and Andalusian women used perfumes for courtship.
Today, fragrances are often marketed as having aphrodisiac qualities, and certain scents are considered to be more seductive or alluring than others. For example, oud is described as "sophisticated, mysterious, and oh-so-seductive", while orris is said to infuse men's fragrances with "opulent elegance".
However, it is important to note that not everyone enjoys fragrances. Some people have fragrance sensitivities that can cause adverse health effects, such as contact dermatitis, migraines, and asthma attacks. It is estimated that as many as 1 in 3 people have some level of fragrance sensitivity, and it can be difficult to avoid fragrances completely, as they are commonly used in personal care products, cleaning materials, and air fresheners.

Fragrances are added to cosmetics and household goods
The Addition of Fragrances to Cosmetics
Fragrances have been used as cosmetics for thousands of years, with early humans using perfumed balms in religious ceremonies. Today, fragrances are commonly added to cosmetics to make them more appealing to consumers. Fragrances can be natural or synthetic, with natural fragrances derived from plants or, in some cases, animals. The aroma compounds found in plants can be extracted through distillation, the most common method, or solvent extraction. Steam distillation, a type of distillation, involves heating raw plant materials over steam and collecting the condensation containing the aroma compounds. These aroma compounds are then cooled and liquefied to create essential oils. Dry distillation, on the other hand, involves heating raw plant materials directly over high heat without water or any other solvent, resulting in a "toastier" aroma. Solvent extraction, a less commonly used method due to its cost and time consumption, involves adding the plant material to a solvent to form a waxy aromatic compound that is then mixed with alcohol to release the essential oils.
The addition of fragrances to cosmetics enhances the user experience by providing a pleasant aroma and masking unpleasant scents from other ingredients. Fragrances have the power to attract, comfort, and excite, as well as alleviate stress and signify cleanliness. They contribute to people's individuality, self-esteem, and personal hygiene. However, it is important to note that fragrances can also cause adverse reactions in some individuals, such as allergic contact dermatitis and asthma flares.
The Inclusion of Fragrances in Household Goods
Fragrances are also added to household goods, such as air fresheners, disinfectants, laundry detergents, scented candles, and surface cleaners. These products are used to improve the indoor environment, particularly regarding odour control. While natural and synthetic fragrances enhance the olfactory perception of these products, they can also negatively impact indoor air quality and human health. The chemicals in synthetic fragrances can be considered emerging contaminants of concern, potentially triggering or intensifying allergic symptoms.
In summary, fragrances are added to cosmetics and household goods primarily to enhance the user experience by providing a pleasant aroma and masking unpleasant odours. However, it is crucial to be mindful of potential adverse health effects, especially for individuals with fragrance sensitivities or allergies.

They can cause health issues like asthma and dermatitis
Fragrances are added to many cosmetic and household products to emit a pleasant smell. However, they can also contain allergens or carcinogenic compounds that may cause health issues such as asthma and dermatitis.
Asthma
Many asthmatics report airway symptoms upon exposure to fragrances and strong odors. Fragrances have been characterized as putative triggers that may exacerbate asthma symptoms. Common triggers include perfumes, household or industrial cleaners, air fresheners, and nail polishes and removers. However, the mechanism by which exposure to pure, non-irritating odorants can elicit an adverse reaction in asthmatic patients is still unclear and may involve both physiological and psychological processes. For example, in one study, asthmatic participants' expectations of harm from exposure to a fragrance altered their perceptual response to the odor and increased their exhaled nitric oxide levels.
Dermatitis
Fragrances and perfumes are one of the most frequently cited substances in personal and cosmetic care products that cause eczema reactions. The chemical substances in some fragrances can cause contact allergic dermatitis in sensitized individuals. Symptoms of irritant contact dermatitis include localized erythema at the site of exposure, dry cracked skin, and blisters and erosions in severe cases. Allergic contact dermatitis is a delayed hypersensitivity reaction and may occur after just one or more exposures. Symptoms are similar, but tiny quantities may be sufficient to trigger an allergic reaction. Fragrance allergy often causes dermatitis of the hands, face, and neck, axillae, and patches in areas where perfumes are dabbed on, such as behind the ears, the upper chest, elbow flexures, and wrists. In men, aftershave products can cause an eczematous eruption of the beard area and the adjacent part of the neck.
Some personal care products such as lotions and soaps are marketed as being "unscented" or "fragrance-free" yet they contain herbal ingredients or oils from botanicals that may contain allergens such as rose oil, vanilla, and sweet almond oil.

Fragrances are bad for the environment and can cause pollution
Fragrances are often needed and used to emit a pleasant smell. They are usually applied to the body in the form of perfumes, colognes, and aftershaves. However, despite their appealing scents, fragrances can have detrimental effects on the environment and contribute to pollution.
Fragrances contain chemical vapors known as volatile organic compounds (VOCs). These VOCs are released into the atmosphere when fragrances are sprayed or applied. Once in the air, VOCs react with sunlight and other chemicals, leading to the formation of ozone pollution and fine particulates. This phenomenon is known as the photochemical reaction, which results in the creation of ground-level ozone, a major component of smog. According to a study by the National Oceanic and Atmospheric Administration (NOAA), emissions from scented products like perfumes, hair sprays, and air fresheners emit the same amount of chemical vapors as petroleum emissions from vehicles, particularly in urban areas like Los Angeles. This finding highlights the significant contribution of fragrances to air pollution, which affects around 90% of the world's population.
The use of fragrances can also lead to water pollution. Synthetic musks, commonly used in fragrances due to their pleasant smell and low cost, have been detected in the sediments and waters of the Great Lakes. These pollutants pose risks to both human and animal health when they enter the food chain. Additionally, the high demand for aromatic materials such as sandalwood, agarwood, and musk has led to the endangerment of these species.
Furthermore, fragrances can have negative health impacts. One-third of the general population experiences adverse health effects from fragranced products. These effects can range from minor issues like irritation and headaches to more severe problems, including asthma flares, allergic contact dermatitis, and potential links to kidney, liver, and nervous system damage. The chemicals in fragrances are often not disclosed on product labels, making it challenging for consumers to make informed choices.
To reduce the environmental and health impacts of fragrances, it is essential to opt for products with lower VOC emissions and avoid excessive use of fragranced items. Additionally, choosing green beauty brands and products with the EWG VERIFIED mark can help minimize potential harm to the environment and personal health.
