Limonene, linalool, and coumarin are common fragrance allergens
Limonene and linalool are fragrance terpenes, and in their oxidized state, they are significant allergens. In fact, they are among the most frequent fragrances encountered by individuals in the UK. A study examining 59 products for men found that linalool (80%) and limonene (76%) were the most prevalent fragrances in items like aftershave. Similarly, in 57 household products, limonene was the predominant fragrance, found in 51% of items such as washing-up liquid and detergent. In a separate study of 44 perfumes for women, limonene (98%) and linalool (95%) were the most frequent fragrances. These chemicals are also common in rinse-off products like shower gels and shampoos, with detection rates of 68.8% and 62.5%, respectively.
Coumarin is often used to create powdery or clean notes and is sometimes associated with floral, vanilla, or Tonka bean scents. It is also useful for providing volume, weight, and opacity to base notes. While coumarin may not be as prevalent as limonene and linalool in certain product categories, it is still a common fragrance allergen. For example, in a study of 51 cosmetics labeled as containing fragrance ingredients, coumarin was identified in 51.4% of leave-on products and 43.8% of rinse-off products. In perfumes and deodorants, coumarin was detected in 73.33% of products, making it the fourth most common fragrance in this category.
The presence of these allergens in fragrances is a growing concern, as evidenced by the development of methods to simultaneously determine the presence of restricted and banned fragrance allergens in cosmetics. Consumers are advised to check ingredient labels and avoid products containing allergens to which they are sensitive. While fragrance ingredients may be listed as parfum or aroma on some products, it is worth noting that only significant allergens like limonene, linalool, and coumarin are typically listed separately on ingredient labels in certain regions, such as the United States.

They are often used in small amounts to create generic floral notes
Limonene, linalool, and coumarin are often listed on fragrances because they are common allergens. Fragrances are the most common chemicals in cosmetics that people are exposed to every day. However, these chemicals can cause unwanted allergic reactions such as contact dermatitis. As a result, regulatory bodies require that these allergens be listed on the ingredients label. It is important to note that the ingredients list is not indicative of the dose of these chemicals in the product.
Limonene, linalool, and coumarin are often used in small amounts to create generic floral notes. For example, in a shower gel, the limonene and linalool may be present in small amounts as part of lemon oil, which is added for its citrus scent. Coumarin is also commonly used in small amounts to create a "powdery" or "clean" note, reminiscent of floral vanilla or Tonka bean. These chemicals can be used to provide volume, weight, and opacity to base notes, often in conjunction with musks and synthetic woods.
The use of these chemicals in fragrances is not limited to creating floral notes. They are also commonly used to create a variety of other scents, including citrus, herbal, and woody notes. For example, limonene is often used in fragrances to create a citrus scent, as it is a major component of the essential oils of citrus fruits. Linalool is known for its floral and citrus notes and is commonly used in fragrances to create a fresh, clean scent. Coumarin, on the other hand, has a sweet scent that can be reminiscent of vanilla or tonka beans, making it a versatile ingredient in creating gourmand fragrances.
The combination of limonene, linalool, and coumarin is highly sought after in the fragrance industry due to their harmonious blend. These chemicals are often used together in scented products such as powders, hand soaps, and room diffusers. Their individual and combined scents are enjoyed by many, and their proportions can be adjusted to create unique fragrances.
While limonene, linalool, and coumarin are frequently used in fragrances, they can also be found in other cosmetic and household products, including shower gels, fabric softeners, and deodorants.
