trans-Sabinyl acetate is a bicyclic monoterpene ester best known as a defining marker of certain wormwood, sage, and Achillea chemotypes. The live evidence base is strongest for identity, chemotype occurrence, and pregnancy-related safety concern signals rather than for broad standalone pharmacology. The most source-grounded use for AromaForge is as a chemistry-and-safety marker constituent: common enough to shape oil character in some profiles, but supported by much thinner isolated-compound efficacy literature than its occurrence data might suggest.
Chemical identity and composition
PubChem's directly readable REST record supports trans-Sabinyl acetate as C12H18O2 with the stereospecific bicyclic acetate structure and a trans-specific InChIKey, while PubChem synonym output exposes CAS 139757-62-3 for the queried record. NIST also lists trans-Sabinyl acetate and (E)-sabinyl acetate as names for the same structure. In archive context, the constituent is especially relevant to low-thujone wormwood and other sabinyl-acetate-rich Asteraceae profiles.
Aroma and practical use
- Use the recorded herbal, green, camphoraceous, fresh 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.
The 2026 low-thujone wormwood paper reported trans-Sabinyl acetate as the predominant constituent at 59.6 +/- 10.1% while trans-thujone remained low.
This is strong support for treating the molecule as a major chemotype marker in selected wormwood oils.
This reference does not establish a therapeutic result or a safe use level for a custom oil blend.
A 2020 Achillea fragrantissima paper reported trans-sabinyl acetate at 20.7 +/- 0.00% in leaves oil and 24.0 +/- 0.19% in stems oil.
This broadens the constituent's archive context beyond Artemisia absinthium and supports its role in Achillea chemotypes.
This reference does not establish a therapeutic result or a safe use level for a custom oil blend.
The 2015 Achillea falcata paper reported that trans-sabinyl acetate belonged to the dominant trans-sabinol ester set and that the tested compounds showed moderate acute toxicity, moderate acetylcholinesterase inhibition, and antinociceptive activity in preclinical models.
The paper is the clearest directly readable source for isolated or semi-isolated bioactivity signals, but the evidence remains preclinical.
This experimental finding does not establish benefit, dose or safety in people using this blend.
A 2021 review on maternal reproductive toxicity of essential oils and constituents summarized trans-sabinyl acetate as a constituent associated in the literature with maternal toxicity, embryo-fetotoxicity, and abortifacient concern.
This is a synthesis source rather than a new experiment, but it is the strongest accessible current framing for pregnancy-related caution.
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 assessed
Not assessed in the available record.
Penetration enhancementNot assessed
Not assessed in the available record.
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 attachedPregnancy-related avoidance is the clearest source-grounded caution in the reviewed literature because sabinyl-acetate-rich oils and review papers repeatedly associate the constituent with embryo-fetotoxic or abortifacient concern.
The source assessment applies to its specified exposure and preparation; this entry is not an unrestricted-use clearance.
The directly readable preclinical paper reports moderate acute toxicity for trans-sabinyl ester-rich testing material, which supports conservative handling language but does not provide a modern full human risk assessment.
This experimental finding does not establish benefit, dose or safety in people using this blend.
A constituent-specific public leave-on dermal maximum or IFRA restriction for isolated trans-Sabinyl acetate was not verified in this pass.
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
moderate acetylcholinesterase inhibition in isolated-compound screening
The main directly readable preclinical paper reports that trans-sabinol esters, including trans-sabinyl acetate, moderately inhibited acetylcholinesterase in vitro.
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)
- Public registry sources disagree on CAS presentation for trans-sabinyl acetate, so the record uses the PubChem trans-specific synonym output while keeping the alternate Good Scents CAS in sources for transparency.
- Human clinical literature specific to isolated trans-Sabinyl acetate was not located in this pass.
- A directly readable modern constituent-specific dermal sensitization or irritation threshold for isolated trans-Sabinyl acetate was not verified.
- 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.
