Ingredient review
Eugenyl Phenylacetate
INCI: EUGENYL PHENYLACETATE
Eugenyl phenylacetate is a synthetic fragrance ingredient that adds a clove-like scent but may cause skin irritation in sensitive individuals.
In plain English
Eugenyl phenylacetate is a man-made chemical used to give products a spicy, clove-like smell. It's a type of ester, which means it's formed by combining an alcohol and an acid. Because it's a fragrance ingredient, it's usually present in very small amounts. While it's considered safe for most people in low concentrations, it can sometimes cause allergic reactions or irritation, especially on sensitive skin. If you have a known sensitivity to fragrance ingredients like eugenol, you might want to avoid products containing this compound.

What it is
Eugenyl phenylacetate is a synthetic ester derived from eugenol (a natural compound found in clove oil) and phenylacetic acid. It is used exclusively as a fragrance ingredient in cosmetics and personal care products.
How it works
In a cosmetic product, eugenyl phenylacetate contributes to the overall scent profile. It does not provide any skincare benefits like moisturizing or anti-aging; its sole purpose is to impart a pleasant fragrance. The molecule evaporates from the skin, releasing its scent.
Pros
Pleasant scent
Provides a warm, spicy, clove-like aroma that can enhance the sensory experience of a product.
Stable in formulations
As a synthetic compound, it is chemically stable and consistent, ensuring the fragrance remains unchanged over time.
Cons and cautions
Potential allergen
Eugenyl phenylacetate is a known fragrance allergen and may cause contact dermatitis in sensitive individuals, especially with repeated use.
No skincare benefit
This ingredient serves only as a fragrance and does not contribute to the efficacy or health of the skin.
Best for
- People who enjoy scented products and do not have fragrance sensitivities
- Those looking for a synthetic alternative to natural clove oil
Use caution if
- Individuals with known fragrance allergies or sensitive skin prone to irritation
Usage tips
Safety summary
Eugenyl phenylacetate is considered safe for use in cosmetics at low concentrations, but it is a recognized fragrance allergen. Individuals with sensitive skin or fragrance allergies should use caution. Regulatory bodies in the EU require specific labeling to alert consumers.
Research notes
Research indicates that eugenyl phenylacetate can cause allergic contact dermatitis in susceptible individuals. Studies are limited, but it is grouped with other fragrance allergens that have been well-documented. The EU Scientific Committee on Consumer Safety has evaluated it and set safe use limits.
Common label clues
- Typical concentration
- Typically used at very low concentrations (under 1%) due to its strong scent and potential for skin sensitization.
- Regulatory status
- Regulated as a fragrance allergen in the EU; must be labeled if concentration exceeds 0.001% in leave-on products or 0.01% in rinse-off products. In the US, it is generally recognized as safe for use in cosmetics by the FDA under current good manufacturing practices.
- Common uses
- Fragranced products, Perfumes, Scented lotions
- Environmental note
- As a synthetic compound, its environmental impact depends on production methods and disposal. It is not known to be bioaccumulative, but limited data exists on its long-term ecological effects.
Good to know
- Eugenyl phenylacetate is often listed under 'fragrance' or 'parfum' on ingredient labels, so it may not always appear by name.
- The European Union requires this ingredient to be listed separately on labels when present above certain concentrations due to its allergenic potential.
