(Z)-gamma-Atlantone is a cedarwood-associated sesquiterpene ketone most clearly documented in Cedrus deodara composition work and registry databases that separate the E and Z isomers. The current accessible evidence base is strong for identity and occurrence but weak for isolated pharmacology or human safety testing. For AromaForge, the most defensible framing is that `(Z)-gamma-atlantone` is a cedar ketone marker with isomer-specific identity and explicit evidence gaps around standalone biological activity.
Chemical identity and composition
NIST indexes (Z)-gamma-Atlantone as a distinct stereoisomer with CAS 108549-48-0, formula C15H22O, and InChIKey QEAHSEZXAQIWSW-BUHFOSPRSA-N. Local oil records already treat it separately from pooled gamma-atlantone, including Himalayan cedarwood records that cite 2.3% (Z)-gamma-atlantone in Cedrus deodara essential oil. This record therefore stays isomer-specific instead of inheriting the ambiguity of the broader gamma_atlantone bucket.
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.
A 2009 Cedrus deodara composition paper reported (Z)-gamma-atlantone at 2.3% in the hydrodistilled essential oil from Himalayan cedar woodchips, supporting its role as a recurring cedar ketone marker.

This reference does not establish a therapeutic result or a safe use level for a custom oil blend.
A turmeric oleoresin extraction comparison reported that roughly 60% of one light fraction consisted of ar-turmerone together with the Z and E gamma-atlantone isomers, showing that gamma-atlantone chemistry is not limited to cedar materials even though the study was not an isolated-compound bioactivity paper.

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 standalone pharmacology literature specific to (Z)-gamma-atlantone was verified in this pass.
- The accessible safety trail is sparse and largely limited to registry or industry-database context rather than toxicology studies.
- Most practical interpretation currently comes from occurrence data in cedarwood and related volatile fractions.
- No IFRA Standard, RIFM assessment, or Tisserand & Young dermal maximum for (Z)-gamma-atlantone was located in two searches; the previous 2% dermal_limit_pct placeholder had no traceable citation and has been removed. phototoxic was also unconfirmed (no citation) and has been set to null pending real data.
- 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.
