Ingredient review
Myrtenol
INCI: MYRTENOL
Myrtenol adds a fresh, pine-like scent to products but may cause irritation in sensitive skin, especially at higher concentrations.
In plain English
Myrtenol is a natural compound found in essential oils like myrtle and pine. In skincare, it's mainly used to give products a pleasant, woodsy or pine-like fragrance. It also has some antimicrobial properties, meaning it can help reduce certain bacteria on the skin. However, because it's a fragrance ingredient, it can be irritating for people with sensitive or reactive skin. You'll usually find it in very small amounts in cleansers, toners, or other scented products.

Quick decision guide
Useful, but context matters
Myrtenol can be useful, but watch for some irritation potential.
Plain-English read
Treat this as a practical screening step before you compare products that contain this ingredient.
- Step 1Start with the score, then check the irritation and clogging risk before judging Myrtenol.
- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.
- Step 3If a product stings, breaks you out, or worsens irritation, judge the finished formula and stop using it even if the ingredient scores well.
Score terms in plain English
Irritation risk
moderateCan bother some users, especially with frequent use, damaged skin, or strong companion ingredients.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
Myrtenol is a monoterpene alcohol that occurs naturally in the essential oils of plants such as myrtle, pine, and other conifers. It is extracted through steam distillation or synthesized for use in cosmetics.
How it works
In cosmetic products, myrtenol primarily functions as a fragrance ingredient, imparting a fresh, pine-like aroma. It may also exhibit antimicrobial activity against certain bacteria and fungi, potentially contributing to product preservation or skin-cleansing benefits, though this is not its primary role.
Pros
Natural fragrance source
Myrtenol is derived from plants like myrtle and pine, offering a natural alternative to synthetic fragrances for those who prefer botanical scents.
Potential antimicrobial effect
Some studies suggest myrtenol can inhibit the growth of certain bacteria and fungi, which may help keep skin cleaner in rinse-off products.
Cons and cautions
Irritation risk for sensitive skin
As a fragrance ingredient, myrtenol can cause redness, itching, or stinging in people with sensitive or compromised skin, especially at higher concentrations.
Limited skincare-specific research
Most studies on myrtenol focus on its antimicrobial or aromatic properties in general, with few direct investigations into its long-term effects in cosmetic formulations.
Best for
- People who enjoy natural, woodsy fragrances in their skincare
- Those with normal to oily skin looking for a fresh-scented cleanser
Use caution if
- Individuals with sensitive, reactive, or eczema-prone skin
- Anyone with a known allergy to pine or myrtle essential oils
Usage tips
Safety summary
Myrtenol is considered safe for use in cosmetics at low concentrations, but it poses a moderate risk of skin irritation and allergic reactions, particularly for those with sensitive skin or fragrance allergies. Regulatory bodies in the EU require it to be labeled as a potential allergen.
Research notes
Research on myrtenol is limited in the context of skincare. Most studies focus on its antimicrobial and antioxidant properties in essential oils, with some evidence of skin sensitization potential. More targeted research is needed to confirm its benefits and risks in cosmetic formulations.
Common label clues
- Typical concentration
- Typically used at very low concentrations, often below 1%
- Regulatory status
- In the EU, myrtenol is regulated as a fragrance allergen and must be listed on the ingredient label if its concentration exceeds 0.01% in leave-on products or 0.001% in rinse-off products. In the US, it is generally recognized as safe for use in cosmetics by the FDA, but no specific concentration limits are set.
- Common uses
- Fragranced products, Cleansers, Toners
- Environmental note
- Myrtenol is typically sourced from steam distillation of plant materials, which is a relatively low-impact process. However, large-scale harvesting of wild plants could affect local ecosystems if not managed sustainably.
Good to know
- Myrtenol is a common allergen listed in EU fragrance allergen regulations, so it must be declared on labels if present above certain levels.
- It is chemically related to pinene, another compound found in pine oils.
