Citronellyl acetate is a rosy-fruity monoterpene ester best known in the AromaForge archive as a supporting constituent in citronella and rose-type oils. The live evidence base is weighted toward identity, occurrence, and fragrance-safety review rather than standalone pharmacology: public sources support its registry identity, repeated occurrence in essential oils, and a modern RIFM assessment reporting no genotoxic concern at current use conditions, adequate systemic margins of exposure, and no expected phototoxicity. Archive positioning should therefore keep citronellyl acetate framed as an aroma and composition marker with stronger safety-review coverage than constituent-specific efficacy evidence.
Chemical identity and composition
NIST and PubChem identify citronellyl acetate as a C12H22O2 monoterpene ester associated with rose-like and citronella-like odor chemistry. In the archive it appears mainly as a secondary ester in citronella and rose materials rather than as a dominant top-line constituent.
Aroma and practical use
- Use the recorded rosy, fruity, sweet, citrus-floral, soft, rose-like descriptors to explore a blend's scent character; perceived strength also depends on the other ingredients.
- Review the flagged use concerns across every contributing oil and the selected dilution.
- Read the route, preparation and experimental context before using a study finding to choose an oil.
Reported benefits and effects
Findings retain their study context. An animal or laboratory result describes that experiment.
RIFM's 2022 safety assessment reported citronellyl acetate as not genotoxic under the reviewed data package.
The published assessment summary states 'Genotoxicity: Not genotoxic' and supports use as described in the safety assessment.
The source assessment applies to its specified exposure and preparation; this entry is not an unrestricted-use clearance.
The same RIFM assessment reported a repeated-dose NOAEL of 500 mg/kg/day and a reproductive-toxicity NOAEL of 200 mg/kg/day.
These values are presented in the human-health summary table alongside exposure-based margin-of-exposure conclusions.
The source assessment applies to its specified exposure and preparation; this entry is not an unrestricted-use clearance.
RIFM reported a skin-sensitization NESIL of 6400 microg/cm2 by read-across and concluded citronellyl acetate was not expected to be phototoxic or photoallergenic.
The full-text safety summary attributes the sensitization endpoint to citronellyl butyrate read-across and the phototoxicity conclusion to UV/Vis data.
The source assessment applies to its specified exposure and preparation; this entry is not an unrestricted-use clearance.
Use concerns and concentration limits
Sensitization concernFlagged
Flagged in the constituent reference; assess the source, route and finished-product concentration.
Phototoxicity concernNot flagged
Not flagged in the current model. This is not proof of absence or unrestricted safety.
Oxidation concernNot flagged
Not flagged in the current model. This is not proof of absence or unrestricted safety.
Penetration enhancementNot flagged
Not flagged in the current model. This is not proof of absence or unrestricted safety.
A recorded constituent reference, not a recommended oil dilution. Product category, source applicability and all contributing oils must be checked before use.
unverified reference · No source provenance attachedPublic safety evidence is stronger than public efficacy evidence for citronellyl acetate; this record should not imply constituent-specific wellness effects that were not directly verified.
This reference does not establish a therapeutic result or a safe use level for a custom oil blend.
No direct public citation is attached to this entry.
The SCCS fragrance-allergen opinion flags citronellol and citronellyl acetate as a corresponding example of potentially related oxidation and hydrolysis allergen systems.
The source assessment applies to its specified exposure and preparation; this entry is not an unrestricted-use clearance.
No direct public citation is attached to this entry.
RIFM's public assessment did not expect citronellyl acetate to be phototoxic or photoallergenic at the conditions evaluated.
The source assessment applies to its specified exposure and preparation; this entry is not an unrestricted-use clearance.
No direct public citation is attached to this entry.
Constituents it may interact with
No constituent-pair interaction is recorded for this identity. The report does not assume either amplification or incompatibility.
How the effects were investigated
likely ester hydrolysis to citronellol and acetic acid
This is a chemistry-based inference consistent with common aliphatic ester metabolism rather than a direct mechanistic paper on citronellyl acetate itself.
This reference does not establish a therapeutic result or a safe use level for a custom oil blend.
oxidation and hydrolysis may converge toward citronellol-related allergenic haptens
The SCCS fragrance-allergen opinion discusses citronellol and citronellyl acetate as a corresponding example for possible cross-reactive oxidation and hydrolysis chemistry.
The source assessment applies to its specified exposure and preparation; this entry is not an unrestricted-use clearance.
What this report cannot establish
- A reported constituent percentage does not establish an effective human therapeutic dose or the amount absorbed into the body.
- The presence of a constituent does not guarantee a clinical benefit, rash treatment or sleep improvement from a custom blend.
- An unflagged concern or missing use limit does not establish safety for ingestion, inhalation, skin exposure or a particular person.
- A candidate constituent interaction does not establish that two oils amplify one another at the selected proportions.
- Constituent descriptors alone do not establish a precise top, heart or base lifetime in a finished blend.
Known data gaps (5)
- This research pass did not verify a strong constituent-specific human efficacy literature for isolated citronellyl acetate.
- The mechanistic handling of citronellyl acetate is mostly inferred from ester chemistry and safety-review metabolism logic rather than direct target-level pharmacology.
- No public primary source was verified here for a standalone IFRA dermal maximum specific to isolated citronellyl acetate.
- The numeric dermal reference lacks source provenance; a verified flag alone is insufficient.
- Some findings do not record an explicit exposure route; consult the linked study before applying them to a use.
