CONSTITUENT REPORT
alpha-Atlantone
Alpha-atlantone is a sesquiterpene ketone closely associated with Atlas and Himalayan cedarwood chemistry in the AromaForge archive. The reviewed literature supports its role mainly as an identity and composition marker rather than as a standalone human-use active: public sources describe it as a recurrent cedarwood ketone, report substantial abundance ranges in Atlas cedarwood oils, and include one odor-focused study showing that atlantones were not the main odor-impact compounds despite their historical reputation. No human clinical evidence or constituent-specific dermal limits were located in the reviewed public sources.
Chemical identity and composition
PubChem lists alpha-atlantone with molecular formula C15H22O and the searched record resolves to the (E)-alpha-atlantone structure. In the archive's cedarwood records, alpha-atlantone appears at 4.81% in one Atlas cedarwood profile and 10.60% in a Himalayan cedarwood GC profile, while a Moroccan Atlas cedarwood composition study reported (E)-alpha-atlantone across samples at 5.2-29.5%.
Aroma and practical use
- Use the recorded woody, cedar-like, dry 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.
cedarwood occurrence range
A composition study summarized in AGRIS and journal indexing reported (E)-alpha-atlantone as one of the major Atlas cedarwood constituents, spanning 5.2-29.5% across sample origins and distillation modes.
Measured: relative abundance range
This reference does not establish a therapeutic result or a safe use level for a custom oil blend.
odor contribution reassessment
A Phytochemistry abstract reported that, in GC-O testing with 12 panelists, the atlantones were odorless while other constituents accounted for the most potent odor-active signals in Atlas cedarwood oil.
Measured: odor-impact ranking
This experimental finding does not establish benefit, dose or safety in people using this blend.
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.
No constituent-specific IFRA leave-on limit, phototoxic restriction, or human tolerability study was located in the reviewed public sources for isolated alpha-atlantone.
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.
Because publicly accessible evidence is centered on analytical chemistry and aroma research rather than direct safety testing of the isolated constituent, safety claims should remain minimal.

olfactory role reassessment
GC-O and aroma extract dilution analysis of Atlas cedarwood oil found that the two most potent odor-active constituents were vestitenone and 4-acetyl-1-methylcyclohexene, while the atlantones were reported as odorless in the assay with 12 panelists.
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 (6)
- No human clinical studies specific to isolated alpha-atlantone were located in the reviewed public sources.
- Public evidence reviewed here does not provide constituent-specific dermal sensitization, phototoxicity, or numeric leave-on restriction data.
- Most accessible literature treats alpha-atlantone as a cedarwood identity or aroma-analysis compound rather than as an isolated pharmacology subject.
- 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.
- Interaction candidates lack an attached source citation and remain unqualified.
