Cinnamyl acetate is a sweet floral-balsamic cinnamyl ester found in cinnamon materials and ylang-ylang profiles already present in the AromaForge archive. The public evidence base is strongest for identity, occurrence, fragrance use, and safety assessment rather than for robust standalone pharmacology. Direct constituent-level anti-inflammatory evidence exists, but it is limited and mostly reported within mixture-constituent screening rather than a deep human or translational literature.
Chemical identity and composition
PubChem and food-flavouring references describe cinnamyl acetate as an acetate ester of cinnamyl alcohol with formula C11H12O2. The archive already records it in cassia, cinnamon bark, and ylang-ylang compositions, where it contributes more to sweet floral-spicy character than to the sharply hot cinnamaldehyde profile.
Aroma and practical use
- Use the recorded sweet, floral, balsamic, spicy, fruity-green 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.
A constituent-screening study on Cinnamomum osmophloeum reported that cinnamyl acetate showed excellent anti-inflammatory activity in LPS-stimulated assays.
The PubMed listing states that cinnamyl acetate had excellent activity among tested constituents from the twig oil.
This experimental finding does not establish benefit, dose or safety in people using this blend.
A 2022 RIFM safety assessment treated cinnamyl acetate as a fragrance ingredient with a formal modern toxicology review.
The PubMed listing confirms a dedicated RIFM fragrance ingredient safety assessment for cinnamyl acetate.
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 attachedModern fragrance safety literature exists for cinnamyl acetate, which is stronger than the constituent's direct pharmacology literature.
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.
Food-flavouring evaluations from JECFA and related references describe no safety concern at current levels of intake when used as a flavouring agent.

No direct public citation is attached to this entry.
This pass did not verify a public aromatherapy-style dermal maximum for isolated cinnamyl acetate.
This reference does not establish a therapeutic result or a safe use level for a custom oil blend.

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
reduced inflammatory mediator production in macrophage-style screening
An accessible constituent-screening study from Cinnamomum osmophloeum reported strong anti-inflammatory activity for cinnamyl acetate in LPS-stimulated assays, but the public snippet does not provide the same target-level depth available for better-studied constituents.
This experimental finding does not establish benefit, dose or safety in people using this blend.
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)
- Direct constituent-level pharmacology for cinnamyl acetate is thin compared with its fragrance and food-safety documentation.
- This pass did not verify a public leave-on dermal limit for isolated cinnamyl acetate.
- Most accessible bioactivity evidence is screening-level or mixture-adjacent rather than human or detailed translational work.
- 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.
