Fragrances are part of many products we encounter every day, from cosmetics and personal care products to laundry detergents and candles. In this post, we provide a general overview of what fragrances are, how they are created, and how they are regulated in the United States.
Top Takeaways:
- Fragrances are compounds used to give products a specific scent and are widely used in cosmetics, personal care products, and household items.
- Fragrance ingredients can be derived from natural sources or created synthetically.
- Thousands of fragrance ingredients exist, most belonging to a few major chemical classes.
- Most fragrances are safe for their intended use, though some individuals may experience sensitivities such as allergies or skin irritation.
What is a fragrance?
Fragrances are substances composed of organic compounds that produce characteristic and often pleasant odors. Manufacturers add fragrance ingredients to products primarily to create a desired scent profile.
Fragrance and flavor compounds can sometimes overlap because they interact with similar sensory pathways in the body. However, ingredients used as flavors are processed and regulated differently from fragrance ingredients used in cosmetic or household products.
Where do we encounter fragrances?
Fragrances appear in many products used in everyday life, including:
- Cosmetics and personal care products
- Toiletries
- Household cleaning products
- Laundry detergents and fabric softeners
- Air fresheners
- Candles and incense
Unless consumers intentionally choose fragrance-free products, most people encounter fragrances regularly through these everyday items.
How are fragrances created?
Fragrance ingredients can be produced using both natural and synthetic approaches.
Natural fragrance ingredients are derived from plants or other natural sources. These compounds are typically extracted through physical or biotechnological processes designed to isolate aromatic compounds.
Synthetic fragrances are created through chemical synthesis and can be categorized into two groups:
- Nature-identical fragrances: Synthesized compounds that have the same chemical structure as substances found in nature.
- Artificial fragrances: Compounds created synthetically that may not occur naturally but provide desirable scent characteristics.
Most fragrance ingredients belong to one of several major chemical classes:
- Alcohols
- Aldehydes
- Ketones
- Esters
- Lactones
Thousands of fragrance ingredients are currently registered and used in product formulations worldwide.
How are fragrances regulated?
In the United States, fragrance regulation depends on the type of product in which the fragrance is used.
Cosmetic products
When fragrances are used in cosmetic products, they fall under the oversight of the U.S. Food and Drug Administration (FDA). Manufacturers are responsible for ensuring that cosmetic products are safe for consumers when used as intended.
Although the FDA does not approve cosmetics before they are marketed, it can take action, including testing products and issuing recalls, if safety concerns arise.
Household products
Products such as laundry detergents, fabric softeners, and air fresheners are generally overseen by the Consumer Product Safety Commission (CPSC). The CPSC can establish safety standards and issue recalls or bans if products pose safety risks.
Drug products
If a fragrance-containing product is marketed with claims to treat or prevent a medical condition (for example, relieving muscle aches), it may be regulated as an over-the-counter drug, meaning it must comply with additional FDA regulations.
Do other organizations support fragrance safety?
Yes. Several organizations support fragrance research and safety evaluation globally.
Two key organizations include:
- International Fragrance Association (IFRA): Maintains standards and guidance for fragrance ingredient use.
- Research Institute for Fragrance Materials (RIFM): Conducts research and safety assessments of fragrance ingredients.
These organizations provide scientific data and guidelines that help manufacturers ensure the safe use of fragrance ingredients in consumer products.

Are fragrances safe?
Manufacturers are legally responsible for ensuring that products sold to consumers are safe when used as intended. As a result, fragrances used in consumer products are considered safe for most individuals.
However, some people may be sensitive to certain fragrance ingredients and experience reactions such as:
- Skin irritation or contact dermatitis
- Asthma symptoms
- Migraines
Individuals with known sensitivities should work with a healthcare professional to identify triggers and select products that meet their needs.
Some concerns have also been raised about specific ingredients used historically in fragrances, including certain phthalates. Current evidence indicates that exposure to the levels typically present in consumer products does not pose a health risk, and harmful phthalates are not permitted in new fragrance formulations.
As with all areas of science, our understanding evolves as new research emerges, and regulatory agencies continue to monitor ingredient safety.
Do companies need to list every fragrance ingredient on the label?
In the United States, manufacturers are not required to disclose individual fragrance ingredients on product labels. Instead, the word “fragrance” or “parfum” may appear as a single entry in the ingredient list, even when that scent is composed of dozens, even hundreds of individual chemical compounds. This practice is permitted in part to protect proprietary formulations, as fragrance blends are often considered trade secrets.
In response to consumer demand for greater transparency, some manufacturers voluntarily disclose fragrance ingredients, and third-party certification programs (such as those recognizing “clean” or “transparent” formulations) help consumers make more informed choices.
The good news.
Humans have used fragrances for thousands of years. Today, advances in chemistry and toxicology allow scientists and manufacturers to better understand fragrance ingredients and evaluate their safety.
As research and technology continue to improve, scientists will gain an even clearer understanding of fragrance ingredients and how they can be used safely in the products people use every day.
