Ingredient review
Myrcenol
INCI: Myrcenol
Myrcenol is a fragrant terpene that adds a pleasant scent to products but may cause irritation in sensitive individuals.
In plain English
Myrcenol is a natural-smelling compound found in plants like hops and lemongrass. In skincare, it's mainly used to give products a fresh, floral, or citrusy scent. While it also has some antioxidant activity, its primary role is fragrance, and it's usually present in tiny amounts. Because it's a volatile essential oil component, it can be a potential irritant for people with very sensitive skin or fragrance allergies.

What it is
Myrcenol is a monoterpene alcohol that occurs naturally in the essential oils of many plants, including hops, lemongrass, and verbena. It is extracted and purified for use as a fragrance ingredient in cosmetics and personal care products.
How it works
In a cosmetic product, myrcenol contributes to the overall scent profile, providing a fresh, floral, or slightly citrusy note. It may also act as a mild antioxidant, helping to neutralize free radicals on the skin's surface, though this effect is secondary to its fragrance function.
Pros
Natural fragrance
Derived from plant sources, myrcenol provides a fresh, floral scent that many users find pleasant and natural.
Mild antioxidant
May offer some free-radical scavenging activity, adding a small protective benefit to the skin.
Cons and cautions
Irritation potential
As a volatile terpene, myrcenol can cause redness, itching, or stinging in people with sensitive or reactive skin.
Limited direct benefit
Its primary role is fragrance, so it doesn't provide significant moisturizing, anti-aging, or barrier-supporting effects.
Best for
- People who enjoy naturally scented skincare products
- Those without known fragrance sensitivities
Use caution if
- Individuals with sensitive skin or a history of fragrance allergies
Usage tips
Safety summary
Myrcenol is generally safe for most people at low concentrations, but it is a known skin sensitizer and can cause allergic reactions in susceptible individuals. Regulatory bodies require it to be listed on labels when present above 0.001% in leave-on products and 0.01% in rinse-off products.
Research notes
Research on myrcenol in skincare is limited. Most studies focus on its fragrance properties and potential as an allergen. Some in vitro studies suggest antioxidant activity, but human clinical data are lacking.
Common label clues
- Typical concentration
- Typically used at very low concentrations (under 1%) as a fragrance component
- Regulatory status
- Approved for use as a fragrance ingredient in cosmetics in the US and EU, but must be listed if present above certain thresholds due to allergen labeling requirements.
- Common uses
- Fragranced products, Cleansers, Moisturizers
- Environmental note
- Myrcenol is typically extracted from renewable plant sources, but its production may involve distillation processes with moderate energy use.
Good to know
- Myrcenol is often listed simply as 'fragrance' or 'parfum' on ingredient labels, so it may not appear by name.
- It is chemically similar to other terpenes like linalool and geraniol, which are also common fragrance allergens.
