Guaia-3,9-diene is a sesquiterpene hydrocarbon occurring as a minor constituent of essential oils.
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 (4)
- Minor/trace constituent; full profile and SEO detail pending. 2026-07-11 verification pass: PubChem CID 585005 synonym list does not expose a CAS registry number (secondary source Chemeo lists CAS 489-83-8, unconfirmed against PubChem/NIST); no constituent-specific dermal limit, sensitization, or phototoxicity data located. 2026-07-13 re-verification: web search for guaia-3,9-diene dermal/sensitization safety data returned only chemical-identity database listings (PubChem, NIST, Chemeo); dermal_limit_pct, sensitizing, phototoxic, and penetration_enhancer remain unverified conservative defaults. 2026-07-13 second-pass verification: fetched NIST Chemistry WebBook directly by InChI (https://webbook.nist.gov/cgi/inchi/InChI=1S/C15H24/c1-10(2)13-7-5-11(3)14-8-6-12(4)15(14)9-13/h10,13H,5-9H2,1-4H3) and confirmed CAS Registry Number 489-83-8 directly from NIST (not merely Chemeo), so cas field has been set. Separately searched "36577-33-0" (the related guaia-6,9-diene CAS) plus IFRA/RIFM for any cross-reference and found no fragrance-safety assessment; a direct search for guaia-3,9-diene IFRA/RIFM dermal data again returned no authoritative results, so dermal_limit_pct, sensitizing, phototoxic, and penetration_enhancer remain unverified.
- No constituent-specific outcome findings are available in this report.
