What it is
Citronellyl Phenylacetate is an ester formed from citronellol (a natural alcohol found in rose and geranium oils) and phenylacetic acid (a compound found in honey and some flowers). It is almost always synthetically produced for consistent quality and safety.
How it works
In a cosmetic product, Citronellyl Phenylacetate acts solely as a fragrance ingredient. It does not provide any skin benefit like moisturizing or anti-aging. It simply evaporates from the skin, carrying its sweet, floral scent to your nose.
Pros
Pleasant Scent
Adds a sweet, rosy-honey fragrance that many find appealing and uplifting.
Low Irritation Risk
At typical use levels, it has a low irritation potential for most skin types.
Cons and cautions
No Skincare Benefit
This ingredient does not moisturize, protect, or improve skin health; it only provides scent.
Potential Allergen
As a fragrance ingredient, it can cause allergic reactions or irritation in sensitive individuals, especially with repeated use.
Best for
- Anyone who enjoys lightly scented skincare products
- People without known fragrance allergies
Use caution if
- Individuals with a known allergy or sensitivity to fragrance ingredients
- Those with very sensitive or reactive skin conditions like eczema or rosacea
Usage tips
Safety summary
Citronellyl Phenylacetate is considered safe for use in cosmetics at typical concentrations. The International Fragrance Association (IFRA) sets usage limits to minimize skin sensitization risk. However, like all fragrance ingredients, it can cause allergic reactions in susceptible individuals.
Research notes
Safety assessments by fragrance industry panels and regulatory bodies have concluded that Citronellyl Phenylacetate is not genotoxic, not a reproductive toxicant, and has low acute toxicity. Skin sensitization potential is low but present, leading to IFRA restrictions on maximum use levels.
Common label clues
- Typical concentration
- Typically used at very low levels, often below 1% in leave-on products
- Regulatory status
- Approved for use in cosmetics in the EU, US, and many other countries. It is subject to fragrance allergen labeling requirements in the EU when present above certain levels.
- Common uses
- Fragranced skincare, Perfumes, Body lotions, Hair products
- Environmental note
- As a synthetic compound, its environmental impact depends on manufacturing practices. Biodegradability data is limited, but many fragrance esters break down relatively quickly.
Good to know
- Citronellyl Phenylacetate is often listed simply as 'fragrance' or 'parfum' on ingredient labels, so it may not appear by name.
- It is not the same as citronellal or citronellol, though they share a similar name.
