Fragrance oils, also known as aroma oils, are artificially created fragrances or scents. They are made to mimic the scent of a natural product but contain artificial substances. Fragrance oils are synthetically manufactured in labs and are often used in perfumes, candles, cosmetics, and food flavourings. They are typically diluted with a carrier like propylene glycol, vegetable oil, or mineral oil. While they are designed to hold their scent for longer than natural fragrances, they may also contain potentially harmful ingredients that can cause adverse reactions, such as skin irritation, allergies, and respiratory issues. Natural fragrance oils, on the other hand, are derived from natural sources such as plants, herbs, and flowers, and are less likely to cause sensitivities.

What You'll Learn
Synthetic vs. natural fragrance oils
Fragrance oils, also called aroma oils, aromatic oils, or flavour oils, are either synthetic or natural. Synthetic fragrance oils are created in a laboratory and contain artificial chemical components not found in nature. On the other hand, natural fragrance oils are made by isolating naturally derived fragrance components from complex scents.
Synthetic Fragrance Oils
Synthetic fragrance oils are created from artificial chemical components that are not found in nature. They are developed in laboratories and are designed to replicate natural scents. Synthetic fragrance oils are widely used in commercial products as they hold their fragrance for much longer than natural fragrances. These oils can be composed of as many as 80 chemical ingredients, and some people may experience skin or fragrance sensitivities when exposed to them.
Synthetic fragrances are often derived from petroleum by-products and can be created through reactive chemistry to have the same chemical structure as natural fragrances. This process is known as nature-identical raw materials, and these synthetic oils do not come from botanicals. For example, synthetic linalool is chemically identical to linalool, which is derived from lavender oil, but it is not derived from a plant.
Natural Fragrance Oils
Natural fragrance oils are made by isolating naturally derived fragrance components from complex scents. These oils are extracted from natural sources such as plants, herbs, flowers, and animals. Examples include limonene, which is derived from lemons, vanillin from vanilla beans, and geraniol from roses. Natural fragrance oils are often more expensive than synthetic oils and are typically sought after by those with sensitive skin or allergies.
Regulation of Fragrance Oils
The International Fragrance Association (IFRA) regulates the levels of certain components in fragrances to ensure that both synthetic and natural fragrances are not harmful to humans. The IFRA only allows fragrances marked as "natural" to contain ingredients that correspond to the definitions set by the International Organization for Standardization. These definitions state that natural aromatic raw materials are physically obtained from plants using distillation, expression, and extraction.

Health risks of synthetic fragrance oils
Synthetic fragrance oils are artificially created fragrances or scents manufactured in a lab to mimic the scent of a natural product. They are often used as a cheaper alternative to natural fragrance oils in perfumes, candles, cosmetics, and food flavorings. However, these synthetic oils can pose several health risks.
One of the main concerns with synthetic fragrance oils is their potential to cause allergic reactions and skin irritation. Fragrance formulas are considered to be among the top five known allergens that can trigger asthma attacks and migraines. Exposure to fragrance chemicals can lead to headaches, eye, nose, and throat irritation, and allergic reactions such as contact dermatitis.
Synthetic fragrance oils have also been linked to endocrine disruption. Phthalates, commonly found in these oils, can interfere with the neuroendocrine system, impacting thyroid hormone signaling and metabolism. This disruption can increase the risk of behavioral and cognitive disorders, including ADHD and autistic behaviors, and can cause reproductive issues and birth defects.
Additionally, synthetic fragrance oils have been associated with respiratory problems. The chemical vapors in these oils, known as volatile organic compounds (VOCs), can contribute to indoor air pollution, making it unhealthy to breathe. This is especially concerning for individuals with respiratory conditions such as asthma.
Furthermore, certain chemicals found in synthetic fragrance oils, such as benzene derivatives, have been linked to cancer. These oils can contain up to 95% petrochemicals, which are known carcinogens. The National Academy of Sciences reported in the 1980s that these chemicals are linked to cancer, birth defects, and central nervous system disorders.
To avoid the potential health risks associated with synthetic fragrance oils, it is advisable to opt for natural fragrance oils or essential oils derived from plants, herbs, and flowers. Consumers should be cautious of products labeled with terms like ""fragrance" or "parfum," as these may indicate the presence of undisclosed and potentially harmful ingredients.

Health benefits of essential oils
Fragrance oils are artificially created scents or perfumes that are synthetically manufactured in a laboratory. They are designed to mimic the scent of a natural product but contain artificial substances. These oils are used in the manufacturing of cosmetics, perfumes, candles, and food flavourings. They are also used to enhance the smell of products like soap. Fragrance oils can cause adverse reactions due to their synthetic nature, and their formulas are considered to be among the top 5 known allergens that can trigger asthma attacks.
Essential oils, on the other hand, are distilled plant extracts that maintain their fragrance and offer various health benefits. Here are some of their health benefits:
- Essential oils are often used in aromatherapy to manage stress and anxiety. For example, orange oil has been found to have an anxiety-reducing effect, and lavender oil can lower self-reported anxiety levels. Bergamot essential oil may also help lower levels of the stress hormone cortisol, improving fatigue and negative emotions.
- Essential oils can help with sleep issues. Aromatherapy may promote relaxation by activating the brain chemicals that control sleep.
- They can be used as a supplementary treatment for headaches. Studies suggest that participants who used lavender, peppermint, and chamomile essential oils reported decreased pain and severity for certain types of tension headaches.
- Essential oils may relieve inflammation-related symptoms like pain, swelling, warmth, and function loss. They can also help with airway inflammation and inflammatory bowel disease (IBD).
- Essential oils can be used to treat nausea and other symptoms like vomiting and retching.
- They can be applied to the abdominal or other affected areas to reduce the severity of muscle pain and menstrual cramping.
- Essential oils have antioxidant properties, which help prevent damage to cells caused by free radicals. This damage can lead to serious diseases such as cancer.
It is important to note that while essential oils offer various health benefits, they should be used with caution. They can have side effects, and improper use can cause adverse reactions or even poisoning. Essential oils should be kept away from children and pets, and anyone who is pregnant should consult a doctor before using them.

How to use fragrance oils
Fragrance oils are synthetic oils that are manufactured to imitate a naturally occurring scent. They are versatile and can be used in several ways.
Using Fragrance Oils on Your Body
Fragrance oils can be applied to your body. When applying fragrance oils, consider applying them to your pulse points, such as your wrists, the inside of your elbows, or behind your knees. These areas will heat up and carry the scent. You can also apply fragrance oils to the back of your neck or your collarbone. Reapply if the scent becomes faint.
Using Fragrance Oils in Your Home
Fragrance oils are a great way to make your home smell nice. You can use them in an oil burner or a diffuser to fill your room with scent. Simply place a few drops of oil and some water into the burner or diffuser, and the oil and water will evaporate as they heat up, spreading the scent. You can also add fragrance oils to a spray bottle with water to create your own air freshener. Spray this mixture into the air to freshen up any room.
Using Fragrance Oils in Other Ways
Fragrance oils can be used in many other ways. You can add a few drops to a cotton ball and place it in your drawer to scent your clothes and linens.

How to store fragrance oils
Fragrance oils are either synthetic or natural. Synthetic fragrance oils are created in labs and are made from artificial chemical components not found in nature. They are often used in commercial products as they hold their fragrance for much longer than natural fragrances. Natural fragrance oils, on the other hand, are made by isolating naturally derived fragrance components from complex scents. For example, limonene is derived from lemons, vanillin from vanilla beans, and geraniol from roses. These oils are better for those with sensitive skin or fragrance allergies.
To store fragrance oils, it is important to keep them in a cool, dark place. The average shelf life of a fragrance oil is anywhere from six to twelve months, but they can last longer if stored in the proper conditions. If stored correctly, fragrance oils can retain their scent and quality for an extended period of time.
When storing fragrance oils, it is also important to keep them away from direct sunlight and heat sources, as this can cause the oil to degrade and the fragrance to fade. Additionally, it is recommended to store the oils in their original containers and ensure that the containers are tightly sealed to prevent oxidation and evaporation.
For those who purchase fragrance oils in bulk, it is advisable to decant the oils into smaller containers to avoid frequent opening and closing of the larger container, which can lead to oxidation and contamination. Storing fragrance oils in smaller containers also makes it easier to manage and control the amount of oil being used, reducing waste.
It is also important to keep fragrance oils away from children and pets, as they can be harmful if ingested. Proper storage and handling of fragrance oils are crucial to maintain their quality, longevity, and safety.
