Di-epi-alpha-cedrene is a sesquiterpene hydrocarbon reported as a minor constituent in essential-oil GC-MS profiles.
Aroma and practical use
No aroma description is attached to this identity yet.
Reported benefits and effects
Findings retain their study context. An animal or laboratory result describes that experiment.
There are no constituent-specific outcome findings in this report. No therapeutic benefit is inferred from its presence.
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.
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 (5)
- Minor GC-MS constituent added during composition completion; profile/SEO detail pending. Bounded identity search (2026-07-11) found multiple non-matching CAS candidates for 'di-epi-alpha-cedrene' isomers (NIST 50894-66-1 vs Cheméo 21996-77-0, PubChem CID 576610), with no way to confirm which isomer matches the Bisht & Hemanthraj sandalwood GC-MS peak, so CAS is left unset rather than guessed. No IFRA/Tisserand/EU Annex III dermal limit, sensitization, or phototoxicity data were found for this constituent.
- Worker c8 search (2026-07-13): di-epi-alpha-cedrene (PubChem CID 10878276) identity confirmed via PubChem/NIST WebBook; note related isomer alpha-cedrene is IFRA-restricted (51st Amendment) as a fragrance allergen-adjacent material, but no constituent-specific RIFM/IFRA dermal or sensitization data for the di-epi isomer itself was located.
- No constituent-specific outcome findings are available in this report.
- No cited aroma description is available for this identity.
- No constituent-specific numeric dermal reference is available here.
