Geijerene is a norsesquiterpene 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. CAS 6902-73-4 confirmed via NIST WebBook in 2026-07-11 verification pass; no constituent-specific dermal limit, sensitization, or phototoxicity data located. 2026-07-13 re-verification: further web search for IFRA/RIFM dermal limit and sensitization data for geijerene found no authoritative constituent-specific results; dermal_limit_pct, sensitizing, phototoxic, and penetration_enhancer remain unverified conservative defaults. 2026-07-13 second-pass retry: retrieved the TGSC safety data page directly (thegoodscentscompany.com/data/rw1559521.html), which confirms Oral/Dermal/Inhalation Toxicity 'Not determined' and 'not for fragrance use'. A separate insecticidal-bioassay search found an LD50 of 35.4 micrograms/larva against insect larvae, but this is an insect-toxicity endpoint, not a human dermal/sensitization safety metric, so it is not usable to set dermal_limit_pct or sensitizing. No human/cosmetic safety monograph located; fields remain unverified conservative defaults.
