gamma-Atlantone is a cedarwood-associated sesquiterpene ketone most strongly linked with Cedrus deodara and related cedar materials, and it also appears in some turmeric volatile fractions. The accessible evidence base is much stronger for identity, isomer naming, and occurrence in GC-MS composition studies than for direct isolated-compound pharmacology or human safety testing. For AromaForge, the most defensible framing is that gamma-atlantone is a cedar ketone marker with pooled E/Z naming complexity and limited standalone biological evidence.
Chemical identity and composition
Public chemistry sources usually index gamma-atlantone as separate E and Z stereoisomers rather than one single registry target. NIST lists both (E)-gamma-Atlantone and (Z)-gamma-Atlantone as C15H22O isomers, while the AromaForge oil archive sometimes pools them under a single gamma_atlantone constituent entry when a supplier GC profile reports combined gamma-atlantone peaks.
Aroma and practical use
- Use the recorded woody, ambery, cedar-like, warm descriptors to explore a blend's scent character; perceived strength also depends on the other ingredients.
- 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.
cedrus deodara extract composition
A PubMed-indexed Cedrus deodara composition paper reported that the solvent-extracted volatile fraction was dominated by E-gamma-atlantone at 38.5% with E-alpha-atlantone at 10.2%, showing that gamma-atlantone can be a major cedar extract marker.

turmeric extract occurrence
A Europe PMC abstract for a turmeric extraction comparison reported that about 60% of the light fraction consisted of ar-turmerone, (Z)-gamma-atlantone, and (E)-gamma-atlantone, indicating that gamma-atlantone is also relevant outside cedarwood chemistry.
Measured: light-fraction composition

Use concerns and concentration limits
Sensitization concernNot flagged
Not flagged in the current model. This is not proof of absence or unrestricted safety.
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.
No numeric constituent-specific use limit is available here. Missing is not an unrestricted-use clearance.
The Good Scents pages for the E and Z gamma-atlantone isomers list them under natural substances and extractives and mark them as not for fragrance use and not for flavor use, but the pages do not provide a modern full toxicology monograph.

No constituent-specific human clinical safety trials, dermal limits, or phototoxicity reviews for isolated gamma-atlantone were located in the reviewed public sources.

Because public registry data are largely isomer-specific, safety interpretation for an unsuffixed pooled gamma-atlantone record should stay conservative.

Constituents it may interact with
No constituent-pair interaction is recorded for this identity. The report does not assume either amplification or incompatibility.
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 (6)
- No strong isolated-compound mechanism or human-use study literature specific to gamma-atlantone was verified in this pass.
- The public identity trail is cleaner for the separate E and Z isomers than for a pooled unsuffixed gamma-atlantone record, so the CAS field is intentionally left null.
- Future upgrades should reconcile whether this archive entry should remain pooled or split into explicit E- and Z-gamma-atlantone records.
- No IFRA Standard exists for gamma-atlantone (E- or Z-isomer), so no category-specific dermal maximum could be sourced; the previously recorded dermal_limit_pct:2 value was not corroborated by any primary source in this pass.
- No constituent-specific numeric dermal reference is available here.
- Some findings do not record an explicit exposure route; consult the linked study before applying them to a use.
