Lavender Essential Oil

At ORY^®, we believe you should know what’s in your products and why. This page lists the published research behind what we say about lavender essential oil. Each section starts with our claim, then tells you how well the research supports it, then lists the sources so you can read them yourself.

Please note: ORY^® uses lavender essential oil mainly as a fragrance ingredient. Some studies on this page tested it in animals, in the lab, by inhalation (aromatherapy), or for medical conditions. FDA treats claims that a product relieves anxiety or stress-related conditions, helps you sleep, eases pain, or treats any condition as drug claims, so ORY^® does not make them.

1. General Description and Role

Verification: Supported, with caveats. Essential oils in cosmetics are regulated as fragrance ingredients. Industry safety limits are set by IFRA Standards, based on safety assessments by the Research Institute for Fragrance Materials (RIFM). We did not locate a Cosmetic Ingredient Review (CIR) conclusion specific to lavender oil.

2. Composition and Production

Verification: Supported. Composition is well documented.

    • What it shows: Review of lavender oil.

3. Skin Type Suitability

Verification: Supported, with caveats. When lavender oil oxidizes, linalyl acetate and linalool form potent contact allergens, so ORY^® uses fresh oil with antioxidants.

Citations:

• • Sköld, M., Hagvall, L., & Karlberg, A. T. (2008). Autoxidation of linalyl acetate, the main component of lavender oil, creates potent contact allergens. Contact Dermatitis, 58(1), 9–14. https://doi.org/10.1111/j.1600-0536.2007.01262.x
    • What it shows: Study of oxidized lavender components.

4. Hair and Scalp Suitability

Verification: Limited evidence. A randomized trial of scalp massage with a blend of essential oils, including lavender, was done in people with alopecia areata, a medical condition. Hair-growth claims are drug claims, and ORY^® does not make them.

    • What it shows: FDA hair-growth rule.

5. Benefits

Verification: Supported, with caveats. Reviews describe antimicrobial and anti-inflammatory activity, mostly in the lab, and a rat study found faster wound healing. Wound-healing and bite-relief claims are drug claims. Claims about mood, stress, or sleep are drug claims under FDA rules, so ORY^® describes only the scent.

6. Use Across ORY^® Product Lines

Verification: Supported. It behaves well in cold-process soap.

    • What it shows: FDA definition of soap; other bars are cosmetics.

7. Pros

Verification: Supported, with caveats. Scent and tradition are well documented; health benefits are not established for cosmetic use.

    • What it shows: Reference.

8. Cons

Verification: Supported. We list these limits so you have the full picture:

• • Oxidation allergy.
  • Adulteration. Lavandin or synthetic linalyl acetate; verify by GC/MS.
  • Not for young children’s products. Rare case reports; ORY^® avoids marketing to young children.
  • Fragrance allergens. Linalool and limonene must be declared on EU labels above set levels; FDA’s U.S. allergen-labeling rule is not yet final.
  • Oxidation. Old oils are more likely to cause allergy.

    • What it shows: Oxidation.

9. Safety Notes

Verification: Supported. Follow these precautions:

• • Patch test any new product on a small area for 24–48 hours before full use.
  • Never apply essential oils undiluted; ORY^® always dilutes them in a carrier or product base.
  • Keep away from the eyes, children, and pets; many essential oils are harmful to cats and dogs.
  • Store tightly closed away from heat and light. Oxidized (old) oils are more likely to cause allergy.
  • If you have a known fragrance allergy, check the ingredient list before use.
  • Stop use if redness, burning, itching, or rash occurs, and talk to a healthcare provider.
  • For external use only. Avoid the eyes unless the product is made for the eye area.
  • If you are pregnant, nursing, have a medical condition, or are buying for a child, ask a healthcare provider before use.
