epi-Zizanal is a sesquiterpene aldehyde 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 (8)
- Minor/trace constituent; full profile and SEO detail pending.
- sensitizing corrected from an unsourced false to null (2026-07-13): epizizanal is an insect-repellent vetiver aldehyde (Weinheimer et al., 'Insect repellents from vetiver oil: I. zizanal and epizizanal', Tetrahedron Lett.); no CAS, IFRA Standard, or RIFM/SCCS assessment specific to isolated epizizanal was located. SCCS notes that Acetylated Vetiver Oil (a chemically distinct acetylated derivative) is a moderate skin sensitizer in test animals owing to reactive aldehyde/ketone constituents, which is suggestive context but not direct evidence for unmodified epizizanal, so sensitizing is left null (unknown) rather than assumed negative.
- Prior citation to sccs_o_167.pdf was fabricated/mismatched and has been removed on QA re-check 2026-07; no verified AVO opinion citation applies directly to epi-zizanal.
- 2026-07-13 second re-verification pass: no CAS number or PubChem CID could be confirmed for epi-zizanal/epizizanal under alternate spellings or the C15H24O formula search; ECHA C&L inventory has no retrievable entry without a CAS number. Dermal limit and sensitizing remain unverified/null; no numeric value set.
- No constituent-specific outcome findings are available in this report.
- No cited aroma description is available for this identity.
- No public source links are attached to this constituent report.
- No constituent-specific numeric dermal reference is available here.
