Dihydrocallitrisin is a eudesmanolide sesquiterpene lactone 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 search (2026-07-11) corroborated the eudesmanolide/Callitris identity via primary isolation (Brecknell & Carman 1978) and total-synthesis (Ireland & Marshall 1970) literature, but no CAS Registry Number or PubChem CID was located, and no IFRA/Tisserand/EU Annex III dermal limit, sensitization, or phototoxicity data were found.
- Worker c8 search (2026-07-13): no CAS number, RIFM/IFRA assessment, or compound-specific safety study located for dihydrocallitrisin. General literature confirms eudesmanolide-type sesquiterpene lactones as a chemical class are recognized contact allergens (e.g., alantolactone, Paulsen 2017/2023 Contact Dermatitis reviews), but this is class-level evidence, not compound-specific, so sensitizing is left unconfirmed rather than set true on inference.
- 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.
