Linalool is found in the essential oils of over 200 plant species, making it one of the most widely used natural fragrance components. While it has a lovely floral, lavender-like scent, it’s a common ingredient in both natural and synthetic fragrances used in personal care products, cleaning products, air fresheners, and even household items.
Even in products that claim to be fragrance-free or unscented, linalool is sometimes included to mask chemical odors or stabilize other ingredients. This can be problematic for individuals who are particularly sensitive or allergic to fragrance ingredients.
Linalool is generally considered safe, but when it oxidizes (exposed to air or light), it can become a sensitizer, meaning it may trigger allergic reactions or irritation in some individuals. People who are prone to fragrance allergies may experience skin rashes, itching, redness, or respiratory discomfort from prolonged exposure to linalool, especially if it's present in high concentrations or oxidized.
While many people turn to "natural" or "organic" products to avoid synthetic chemicals, it’s important to note that linalool is still considered a natural fragrance compound, even though it can cause allergic reactions in sensitive individuals. Just because a product is labeled as natural or organic doesn't necessarily make it free from potential allergens like linalool.
Many products labeled as "fragrance-free" or "unscented" can still contain linalool and other fragrance ingredients. "Fragrance-free" generally means no added fragrances, but it does not guarantee that the product is completely free of compounds like linalool. "Unscented" often means that no specific fragrance is added, but it may still contain ingredients to mask odors, including linalool.
Linalool is more likely to cause allergic reactions when it has oxidized. This means that products containing linalool, especially older ones, may become more allergenic over time. This oxidation is more likely to occur in products that are exposed to air over long periods, such as open perfumes, lotions, or body sprays.
People may not always recognize linalool as an allergen because it’s often hidden in the ingredient list under terms like “fragrance,” “natural fragrance,” or “essential oils.” For individuals with fragrance allergies or sensitivities, it’s important to be diligent about reading labels on personal care, household, and cleaning products.
For those with fragrance allergies or sensitivities, there are fragrance-free or hypoallergenic products available that do not contain linalool. Opting for products labeled as “sensitive skin” or “hypoallergenic” can reduce exposure to linalool, though it’s still important to read ingredients thoroughly.
Children, people with asthma, and individuals with eczema or sensitive skin may be at higher risk of developing sensitivities or allergic reactions to fragrance compounds like linalool. It’s crucial for caregivers and people with chronic skin conditions to choose products carefully and consult a healthcare professional if unsure about a product's safety.
If readers suspect they are allergic to linalool or other fragrance compounds, it is advisable to consult a healthcare provider for advice. They may recommend patch testing for specific allergens or suggest products formulated specifically for sensitive skin.
What to look for on Ingredients Labels
Fragrance can go by many names, such as:
Parfum
Fragrance
Masking Fragrance
Linalool
Coriandrol
Other chemical names of linalool are 2,6-dimethylocta-2,7-dien-6-ol;
β-linalool;
linalyl alcohol;
linaloyl oxide;
p-linalool;
allo-ocimenol;
and 3,7-dimethyl-1,6-octadien-3-ol.
The scientific name for the compound generally referred to as "Fragrance" is Linalool.
When used as a food additive, it may be called Coriandrol.
Linalool is used as a scent in perfumes, hygiene products, cleaning products, detergents, shampoos, lotions, etc.
It is even found in many first-aid and personal care products that are used on sensitive areas, such as tampons or pads, hydrocortisone cream, antiseptic sprays, even in some calamine lotions used to calm allergic skin reactions—highlighting just how serious and absurd it is to have to scrutinize every label to avoid fragrance in products that it has no business being in.
Lavender (20-35%)
Cannabis
Coriander/Cilantro
Lemongrass/Citronella Grass
Goldenrod
Mugwort
Hops
Basil
Bay Laurel

Chemical derivatives
Linalool is hydrogenated to give dihydro- and tetrahydrolinalool, which are fragrances that are more resilient toward oxidants, as might be found in household cleaning products. Linalyl acetate, a popular scent, is produced by esterification of linalool (as well as occurring naturally). Isomerization of linalool gives geraniol and nerol.
Fragrance allergy is not uncommon!
Linalool can be absorbed by inhalation of its aerosol and by oral intake or skin absorption, potentially causing irritation, pain and allergic reactions.[3][19] Some 7% of people undergoing patch testing in Europe were found to be allergic to the oxidized form of linalool.[20]

What is Linalool and Where is it Found?
Linalool is a naturally occurring compound known for its sweet, floral, and slightly spicy aroma. It belongs to the terpene family and is widely found in the essential oils of various plants. Common in nature and everyday products, linalool adds fragrance to perfumes, cosmetics, and household goods.
Natural Sources of Linalool:
Flowers: Lavender, rose, and jasmine owe much of their signature scents to linalool.
Herbs: Basil, mint, and coriander are rich in linalool, contributing to their aromatic profiles.
Trees: Birch trees produce linalool as part of their essential oil, offering a subtle woody and slightly sweet fragrance.
Fruits: Citrus fruits like oranges, grapefruits, and lemons have linalool in their rinds.
Spices: Cinnamon, nutmeg, and clove contain trace amounts of linalool.
Products Containing Linalool:
Linalool is used extensively in:
Fragrances: Perfumes, colognes, and scented candles.
Personal Care Products: Shampoos, lotions, and soaps for their relaxing or invigorating aromas.
Cleaning Products: Detergents and air fresheners for a fresh, pleasant scent.
Health and Allergen Considerations:
While linalool is naturally occurring and generally safe, it can oxidize when exposed to air, potentially triggering allergic reactions in sensitive individuals. Those with fragrance allergies or sensitivities should check product labels carefully, as linalool can be found either as a listed ingredient or as part of essential oils derived from the plants above.
If you're concerned about linalool exposure, consult a healthcare provider for guidance on managing allergies and identifying safe products.
The Price of Allergies
If you are struggling with finding fragrance-free products you've probably concluded that avoiding this allergen is expensive.
There are a few ways to offset the cost.
For individuals with a fragrance allergy, it is possible to use funds from a Health Savings Account (HSA) or Flexible Spending Account (FSA) to purchase fragrance-free hygiene products if they have a Letter of Medical Necessity (LMN) from a healthcare provider. Here's an overview of the process:
1. Identify the Need for the Letter
A fragrance allergy is a legitimate medical condition that can cause skin irritation, respiratory problems, or other allergic reactions. Many hygiene products contain fragrances that exacerbate these symptoms, making fragrance-free options a necessity rather than a preference. This need qualifies under many HSA and FSA guidelines when supported by a doctor’s letter.
2. Schedule a Doctor's Appointment
Make an appointment with your healthcare provider to discuss your allergy and how it impacts your daily life. Be prepared to provide:
A detailed history of your allergy symptoms.
Documentation of any past reactions to fragranced products.
Examples of the types of fragrance-free products you need (e.g., soap, shampoo, deodorant, pads, or tampons).
3. Request a Letter of Medical Necessity
Ask your doctor to write an LMN specifying that you require fragrance-free hygiene products to manage your medical condition. The letter should include:
Your name and the date.
A description of your fragrance allergy and the medical necessity of using fragrance-free products.
A list or general category of the products required (e.g., "fragrance-free personal care and hygiene products").
The doctor’s signature, credentials, and contact information.
4. Submit the Letter to Your HSA/FSA Administrator
Send the LMN to your HSA or FSA plan administrator. Each plan has its own process for submitting documentation, so check their specific requirements. Some may request additional paperwork or forms.
5. Keep Records for Future Purchases
Once approved, keep a copy of the LMN for your records. You may need to submit receipts for reimbursement or to confirm eligibility of the products you purchase.
6. Renew the Letter as Needed
Most HSA and FSA plans require LMNs to be renewed annually. Be sure to schedule a follow-up appointment with your doctor before the letter expires to avoid any gaps in coverage.
By obtaining an LMN, you can use pre-tax dollars from your HSA or FSA to cover the cost of essential fragrance-free products, helping to alleviate the financial burden of managing your allergy.
For individuals with a fragrance allergy, getting a prescription for over-the-counter (OTC) products like fragrance-free hydrocortisone cream or calamine lotion, etc. can help ensure access to necessary treatments and may allow for reimbursement through an HSA or FSA. Here's how the process works:
1. Understand the Need for a Prescription
While OTC products like hydrocortisone cream are widely available, many versions contain fragrances or other irritants that can exacerbate symptoms in those with fragrance allergies. By obtaining a prescription for a fragrance-free version, you ensure access to a safe product tailored to your medical needs. A prescription can also qualify the expense for reimbursement through an HSA or FSA, as prescribed items are eligible for these benefits.
2. Consult Your Doctor
Schedule an appointment with your healthcare provider and explain your allergy, including any past reactions to fragranced products. Discuss the need for a fragrance-free formulation of the specific product you require. Be prepared to share:
Specific examples of reactions you've had to fragranced versions of OTC products.
The name of the product you believe will work best for you (e.g., fragrance-free hydrocortisone cream).
3. Request a Prescription
Ask your doctor to write a prescription for the fragrance-free version of the product you need. The prescription should clearly specify:
The product name (e.g., "fragrance-free hydrocortisone cream").
The required formulation (e.g., fragrance-free, dye-free, or alcohol-free if applicable).
The dosage or instructions for use (e.g., "Apply to affected area up to 4 times daily").
If your doctor is unfamiliar with the need for fragrance-free versions, you can provide examples of available products or ask them to consult with a pharmacist.
4. Fill the Prescription at a Pharmacy
Take the prescription to your pharmacy. Depending on the product, they may carry a fragrance-free version or order one for you. If it is unavailable, your pharmacist may be able to compound a fragrance-free version.
5. Use Your HSA or FSA for Coverage
Once you have the prescription, you can use HSA or FSA funds to cover the cost of the product. Keep the prescription and receipt as documentation, as you may need to submit them for reimbursement or record-keeping purposes.
6. Discuss Alternatives if a Prescription Isn’t Possible
If obtaining a prescription isn’t an option, consider asking your doctor for a Letter of Medical Necessity (LMN) for fragrance-free OTC products. Many HSA and FSA plans accept LMNs for products used to treat a medical condition.
By working with your doctor to secure a prescription for fragrance-free OTC products, you can safeguard your health and potentially reduce out-of-pocket costs through tax-advantaged accounts like HSAs or FSAs. This approach ensures you get the care you need without risking exposure to allergens.
Some insurance plans may consider reimbursing OTC products if a doctor writes a prescription for them. This is more likely if the product is medically necessary for treating a specific condition, such as a fragrance-free hydrocortisone cream for a fragrance allergy. You’ll need to check with your insurance provider to confirm their policy on reimbursing prescribed OTC items.
Insurance companies are more likely to reimburse OTC products if:
The product is required to treat a chronic condition or allergy.
The prescribed OTC is a less expensive alternative to a prescription-only medication.
The product is unavailable in a prescription form, but a medically necessary version exists OTC.
While standard health insurance may not cover OTC products, a prescription allows you to use Health Savings Account (HSA) or Flexible Spending Account (FSA) funds to pay for them. With a valid prescription or a Letter of Medical Necessity (LMN):
HSA/FSA funds can be used for the cost of OTC medications, including fragrance-free options.
Documentation of the prescription must be retained for tax purposes.
For OTC products that are critical to managing a medical condition, you can sometimes request prior authorization from your insurance company. This involves:
Submitting your doctor’s prescription along with a medical justification for the OTC product.
If approved, the product may be reimbursed as an exception.
For individuals on Medicaid or other state-funded healthcare programs, there may be specific provisions for reimbursing prescribed OTC products. Policies vary by state and plan.
Check Insurance Coverage: Call your insurer and ask if they reimburse prescribed OTC items. Provide details about the product and medical necessity.
Consult a Pharmacist: Some pharmacies know which products might be covered or how to submit claims for prescribed OTC items.
Save Documentation: Always keep a copy of the prescription and your receipt, as you may need them for reimbursement or to use HSA/FSA funds.
While direct reimbursement from insurance is rare for OTC products, using HSA/FSA funds or seeking prior authorization can help offset costs for medically necessary items.
