Fragrance oils are everywhere, from candles to laundry detergent. While they may seem harmless, some fragrance oils can have adverse effects on human health and the environment. Synthetic fragrance oils, also known as fragrance oils, are produced from man-made materials such as petrochemicals, which can cause serious health issues like cancer and endocrine disruption. Even essential oils, which are considered non-toxic, can trigger headaches and be toxic to certain individuals based on age or medical history. It is important to be cautious when handling fragrance oils and to follow safety guidelines to prevent skin and eye contact and reduce inhalation.

What You'll Learn
Potential health risks of fragrance oils
The potential health risks of fragrance oils are varied and depend on the type of oil, the method of administration, and the individual's age and medical history. It is important to note that fragrance oils are not inherently dangerous, but certain risks should be considered.
Firstly, fragrance oils can cause adverse reactions when they come into contact with the skin. This includes rashes, itching, chafing, and chemical burns. To mitigate this, it is recommended to wear gloves and aprons when handling fragrance oils to prevent direct skin contact.
Inhalation of fragrance oils can also lead to several health issues. Airborne molecules of the oil interact with our olfactory organs and are carried to our lungs, potentially affecting our entire body. Inhalation can cause coughing, wheezing, difficulty breathing, nausea, vomiting, and severe headaches. More severe long-term health concerns from unprotected use include cancer, lung disease, brain damage, and heart disease. To reduce the risk of inhaling fragrance oils, masks are recommended to minimize fume inhalation and protect respiratory health.
Additionally, certain fragrance oils may contain toxic chemicals, such as phthalates, parabens, formaldehyde, lead, and talc. These chemicals have been linked to hormone disruption, cancer, endometriosis, infertility, developmental disorders, neurological issues, and allergies. Synthetic fragrances, in particular, are produced from petrochemicals and can include endocrine disruptors, known carcinogens, and neurotoxicants. Endocrine disruptors can interfere with growth, development, intelligence, and reproduction, and the damage can be irreversible and passed on to future generations.
It is worth noting that essential oils, which are highly concentrated plant substances, can also trigger headaches when inhaled in their undiluted form. Some essential oils can be toxic to certain individuals, depending on age and medical conditions, and can even be dangerous to pets when inhaled in their pure form.
To minimize potential health risks, consumers should opt for fragrance oils that are certified as safer by reputable third-party programs, such as EPA's Safer Choice or GreenSeal. Reading ingredient lists, assessing product toxicity, and choosing products with simple and natural ingredients can also help reduce exposure to potentially harmful chemicals in fragrance oils.

Safety measures when handling fragrance oils
Fragrance oils can be dangerous if not handled correctly. It is important to take safety measures when handling these oils to protect yourself and those around you. Here are some detailed safety measures to follow when working with fragrance oils:
Read the Safety Data Sheet (SDS)
Before using any fragrance oil, take the time to read through the SDS provided by the manufacturer. This document contains crucial information about the oil's hazards, safety measures, disposal, transportation, and storage. It will also inform you of the protective equipment you should wear and any exposure limits. Understanding the SDS will help you handle the oil responsibly and safely.
Protect Your Eyes and Skin
Fragrance oils can cause irritation, rashes, and burns if they come into contact with your skin or eyes. Always wear safety goggles to protect your eyes, ensuring the strap is snug but not too tight. Consider wearing gloves, preferably latex or rubber, to prevent the oil from absorbing into your skin and reducing the risk of adverse reactions. An apron, especially one made of leather or rubber, can also help protect your clothes and skin.
Ensure Proper Ventilation
Fragrance oils can release fumes and vapors that can be harmful if inhaled. Work in a well-ventilated area to minimize the risk of inhaling these vapors. Wearing a mask can also help reduce fume inhalation and protect your respiratory system.
Store and Transport Safely
Proper storage is essential to maintain the quality of fragrance oils and prevent accidents. Store the oils in a cool, dry place away from direct sunlight, and if possible, transfer them to smaller bottles to reduce oxidation. Keep fragrance oils away from heat sources and open flames as some oils are highly flammable. Additionally, follow the transportation guidelines in the SDS to safely move or ship the oils, including any special labels or handling instructions.
Keep Out of Reach of Children and Pets
Some fragrance oils can be highly toxic if ingested, and their appealing scents may attract children and pets. Always keep them out of reach and never leave them unattended.

Health impact of synthetic fragrances
The use of synthetic fragrances, also called "fragrance oils", poses several health risks. These fragrances are produced from man-made materials, particularly petrochemicals (petroleum-based chemicals), and can contain a complex mixture of several dozen to several hundred synthetic compounds.
When inhaled, the airborne molecules of synthetic fragrances interact with our olfactory organs, sending signals to the limbic system in our brain, which is the centre of emotions. However, these molecules also reach our lungs and can, therefore, affect our entire body. The health risks associated with exposure to synthetic fragrances include:
- Endocrine disruption: Petrochemicals and their byproducts, such as dioxin, are known endocrine disruptors, interfering with hormones, growth, development, intelligence, and reproduction. This can lead to issues such as hormone disruption, endometriosis, infertility, and developmental disorders. The damage caused by endocrine disruptors can be irreversible and passed on to future generations.
- Cancer: Certain synthetic chemicals in fragrances are known carcinogens, increasing the risk of cancer.
- Neurological issues: Synthetic fragrances can contain neurotoxicants that affect the nervous system, potentially leading to neurological disorders, behavioural issues, and cognitive problems. Phthalates, commonly found in fragranced products, have been linked to autism, symptoms of ADHD, and neurological disorders.
- Allergic reactions: Synthetic fragrances can trigger allergic responses such as headaches, migraines, difficulty breathing, sinus irritation, and contact dermatitis.
- Respiratory problems: Exposure to synthetic fragrances can cause respiratory difficulties, coughing, wheezing, and nausea.
- Other health concerns: Prolonged exposure to fragrance oils without proper safety measures can contribute to long-term health issues, including lung disease, brain damage, and heart disease.
It is important to note that the impact of synthetic fragrances can vary based on age group, medical conditions, and individual sensitivity. Additionally, certain essential oils considered non-toxic to humans can be toxic to pets when inhaled in their pure form.
To reduce the potential health risks associated with synthetic fragrances, consumers can opt for fragrance-free or naturally scented products, choose products certified as safer by reputable third-party programs, and refer to apps or third-party sources that provide information on the ingredients and potential hazards of personal care products.

Natural fragrances as an alternative
Natural fragrances are a great alternative to synthetic fragrance oils, which can be harmful to health. Natural fragrances are derived from plants, flowers, or animals, and can be used to create a natural, appealing scent for products.
Natural fragrances, or essential oils, are highly concentrated plant extracts with therapeutic benefits. They are a complex mixture of terpenes and other aromatic or aliphatic compounds, produced as secondary metabolites in specialised secretory tissues of aromatic plants. They are volatile, which makes them useful as fragrances, but they also have other functions in cosmetics. For example, they can act as preservatives and active agents, while also offering benefits to the skin.
There are several methods of extracting essential oils from plants, including steam distillation, expression (physical crushing of essential oil glands), microwave-assisted extraction, solvent extraction, and enfleurage (transfer of essential oil from flower petals to fat). Steam distillation is the most common method, while expression is commonly used to obtain essential oils from citrus fruit peels.
Essential oils are used as fragrances in cosmetics and personal care products, including soaps, toothpastes, mouthwashes, deodorants, and bath products. Some of the most valued essential oils used as fragrances include citrus, lavender, eucalyptus, tea tree, and other floral oils.
Other natural alternatives to fragrance oils include hydrosols, CO2 extracts, and botanical extracts. Hydrosols are safer, less expensive, and more user-friendly than essential oils, and can be used around children and pets. They do not usually need to be diluted and have therapeutic properties. CO2 extracts can provide a natural aroma and added therapeutic benefits, such as skin regeneration and soothing sensitive skin. Botanical extracts can provide a delightful aroma that enhances the experience of using skincare products.
It is important to note that even natural fragrances can cause adverse reactions in some people. For example, some essential oils can trigger headaches when inhaled, and many essential oils can have toxic effects on certain age groups (such as babies, young children, or older people) or individuals with certain medical conditions (such as epilepsy). Additionally, some essential oils are dangerous to pets when inhaled in their pure form. Therefore, it is important to always follow safety guidelines when handling any type of fragrance, natural or synthetic, and to choose products that are certified as healthier for humans and the environment.

Regulations and labelling of fragrance oils
The regulations and labelling requirements for fragrance oils can be complex and depend on various factors, including the intended use, marketing claims, and ingredients. Here is a detailed overview:
Regulations
The US Food and Drug Administration (FDA) regulates fragrance oils based on their intended use. If a fragrance oil is intended to be applied to a person's body to enhance their attractiveness, it is considered a cosmetic under the law. On the other hand, if the fragrance oil is meant for therapeutic uses, such as treating diseases or affecting the body's structure or function, it is regulated as a drug. The distinction between cosmetics and drugs is crucial because drugs must be approved by the FDA before distribution, while cosmetics are FDA-regulated but not FDA-approved.
Additionally, the term “essential oils” does not have a regulatory definition. However, if an "essential oil" or "aromatherapy" product claims to treat health issues or improve well-being, it may be considered a drug. It's important to note that the FDA does not have regulations defining "natural" or "organic" for cosmetics, and plant-based ingredients can still be regulated as drugs.
Labelling
Fragrance oils intended as cosmetics must meet specific labelling requirements. They must include a list of ingredients, with each ingredient listed individually in most cases. However, under US regulations, fragrance and flavour ingredients can be collectively listed as "fragrance". Cosmetic labels must also include instructions for safe use and warning statements when necessary to prevent health hazards.
The Fair Packaging and Labeling Act applies to cosmetic fragrance oils, requiring specific information on the labels. However, manufacturers are not obligated to disclose trade secrets. If essential oils are identified as "fragrance", marketing text can still highlight the use of specific essential oils. In the US, the common name of the plant part and form should be used (e.g., "Orange peel oil"), while other countries like Canada and Europe use the scientific name (e.g., "Citrus sinensis peel oil").
To ensure compliance, labels should be designed to be durable and legible, as information that is obscured or crowded may violate cosmetic product labelling regulations. Waterproof labels are recommended to prevent damage from oil drips or wet hands.
