Dihydrocitronellyl Acetate
INCI: DIHYDROCITRONELLYL ACETATE
A synthetic scent ingredient that makes products smell pleasant but offers no skincare benefit and may trigger sensitivity in some people.
In plain English
Dihydrocitronellyl acetate is a man-made chemical that smells like a mix of fresh flowers and fruit. It is added to skincare and beauty products purely for fragrance. It does not moisturize, treat, or improve your skin in any way. While generally considered safe at low levels, it can cause irritation or allergic reactions in people with sensitive skin or fragrance allergies.

Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
moderateThere is useful support, but formula details and claim strength still matter.
What it is
Dihydrocitronellyl acetate is a synthetic ester created by combining an alcohol (dihydrocitronellol) with acetic acid. It belongs to a family of fragrance ingredients known for their pleasant, long-lasting scent.
How it works
In a cosmetic product, dihydrocitronellyl acetate acts solely as a fragrance ingredient. It evaporates from the skin, releasing a pleasant scent. It does not interact with the skin's structure or provide any functional benefit like hydration or protection.
Pros
Pleasant scent
Adds a fresh, floral-fruity aroma that can make your skincare routine more enjoyable.
Low irritation for most
At typical low concentrations, it is well-tolerated by the majority of people without fragrance sensitivities.
Cons and cautions
No skin benefit
This ingredient does nothing for your skin's health—no hydration, anti-aging, or barrier support.
Allergen potential
It can trigger contact dermatitis or allergic reactions in people with fragrance sensitivities, leading to redness, itching, or rashes.
Best for
- People who enjoy scented skincare and do not have fragrance sensitivities
- Those using products where a pleasant scent enhances the experience
Use caution if
- Individuals with known fragrance allergies or very sensitive skin
- Anyone following a fragrance-free skincare routine to minimize irritation risk
Usage tips
Safety summary
Dihydrocitronellyl acetate is generally recognized as safe for use in cosmetics at low concentrations by regulatory bodies. However, it is a known skin sensitizer and can cause allergic reactions in susceptible individuals. The risk is low for most people but real for those with fragrance allergies.
Research notes
Research indicates that dihydrocitronellyl acetate has a moderate potential for skin sensitization. It is included in fragrance allergen lists by the EU SCCS and the International Fragrance Association (IFRA) sets usage limits to minimize risk. No significant systemic toxicity has been reported from cosmetic use.
Common label clues
- Typical concentration
- Typically used at very low levels (under 1%) in leave-on and rinse-off products.
- Regulatory status
- Approved for use in cosmetics in the US (FDA) and EU (CosIng). In the EU, it must be listed on the label if present above 0.01% in leave-on products or 0.001% in rinse-off products due to allergen labeling requirements.
- Common uses
- Perfumes, Body lotions, Cleansers, Moisturizers
- Environmental note
- As a synthetic compound, it is not biodegradable in all conditions and may accumulate in the environment, though at low levels from cosmetic use.
Good to know
- Dihydrocitronellyl acetate is often listed simply as 'fragrance' or 'parfum' on ingredient labels, making it hard to spot unless the brand provides full disclosure.
- It is considered a moderate allergen by the European Union's Scientific Committee on Consumer Safety (SCCS) and must be listed separately on products sold in the EU if above certain levels.
