What it is
Citronellyl Acetate is an ester formed from citronellol and acetic acid. It occurs naturally in many plants, especially in rose, geranium, and citronella oils, and is also produced synthetically for use in fragrances.
How it works
In a cosmetic product, Citronellyl Acetate acts solely as a fragrance ingredient. It evaporates from the skin, releasing its scent. It does not have any known moisturizing, anti-aging, or other skincare functions.
Pros
Pleasant natural scent
Adds a fresh, rose-like fragrance that many find appealing, improving the overall user experience.
Widely used and accepted
Common in many products, so it's easy to find and generally considered safe at low concentrations.
Cons and cautions
Potential allergen
Classified as a common allergen by the EU Cosmetics Regulation, meaning it can cause contact dermatitis in sensitive individuals.
No skincare benefit
Provides only fragrance, not hydration, protection, or any active skincare function.
Best for
- People who enjoy floral-scented products
- Those without known fragrance allergies
Use caution if
- Individuals with sensitive skin or a known allergy to fragrance ingredients
Usage tips
Safety summary
Citronellyl Acetate is considered safe for most people at the low concentrations used in cosmetics. However, it is a recognized contact allergen, so individuals with fragrance sensitivities should avoid it.
Research notes
Research confirms that Citronellyl Acetate is a common fragrance allergen, with patch test studies showing positive reactions in a small percentage of the population. No evidence supports any skincare benefits beyond fragrance.
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 US (FDA) and EU, but must be listed on the label when present above 0.001% in leave-on products and 0.01% in rinse-off products due to allergen potential.
- Common uses
- Fragranced lotions, Perfumes, Body washes, Shampoos
- Environmental note
- Naturally derived from plant sources, but synthetic versions are also common. Environmental impact is low at typical usage levels.
Good to know
- Citronellyl Acetate is often listed on ingredient labels because it is a known allergen that must be declared above certain levels in the EU.
- It is naturally present in many essential oils, so products labeled 'natural' may still contain it.
