(Z)-Lanceol is a sandalwood-linked sesquiterpene alcohol documented mainly as a supporting constituent of Santalum oils rather than as a well-studied standalone active. Live identity sources clearly support the `(Z)-lanceol` naming set and CAS assignment, while accessible composition papers place it in Hawaiian, Australian-grown, and other sandalwood profiles. The direct pharmacology and toxicology literature is sparse, so this record is best used as a chemistry and authenticity marker with honest evidence gaps.
Chemical identity and composition
NIST lists (Z)-Lanceol as C15H24O with CAS 10067-28-4 and maps it to the same structure as cis-lanceol and beta-bisabolen-12-ol. Local oil files already use `z_lanceol` in sandalwood records, including Hawaiian sandalwood and plantation-grown Santalum album, which supports keeping a separate isomer-explicit record rather than relying only on the neighboring cis_lanceol entry.
Aroma and practical use
- Use the recorded woody, soft, sandalwood-like, dry descriptors to explore a blend's scent character; perceived strength also depends on the other ingredients.
- Review the flagged use concerns across every contributing oil and the selected dilution.
- Read the route, preparation and experimental context before using a study finding to choose an oil.
Reported benefits and effects
Findings retain their study context. An animal or laboratory result describes that experiment.
A 2014 Hawaiian sandalwood composition paper reported (Z)-Lanceol at about 2.0-4.6% across four commercial Santalum paniculatum oils, supporting its role as a recurring analytical component of Hawaiian sandalwood aroma profiles.

This reference does not establish a therapeutic result or a safe use level for a custom oil blend.
A publicly readable Australian plantation-grown Santalum album GC/MS report listed (Z)-Lanceol at 2.8%, showing that the constituent also appears in genuine plantation-grown Indian sandalwood material outside the Hawaiian dataset.

Use concerns and concentration limits
Sensitization concernFlagged
Flagged in the constituent reference; assess the source, route and finished-product concentration.
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.
The Good Scents entry for (Z)-lanceol shows no determined oral, dermal, or inhalation toxicity values on the accessible page and should not be treated as a standalone safety monograph.
This reference does not establish a therapeutic result or a safe use level for a custom oil blend.
No direct public citation is attached to this entry.
No constituent-specific human safety study, IFRA dermal limit, or phototoxicity review for isolated (Z)-lanceol was verified in this pass.

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 (6)
- No strong isolated pharmacology literature for (Z)-lanceol was verified in the accessible public sources reviewed here.
- Safety data for the isolated constituent are much thinner than occurrence data in sandalwood oils.
- Mechanism claims would be speculative at this stage and are intentionally omitted.
- No IFRA Standard, RIFM assessment, or Tisserand & Young dermal maximum for (Z)-lanceol was located in two searches; the previous 20% dermal_limit_pct placeholder had no traceable citation and has been removed. One secondary source (scent.vn) listed CAS 10067-29-5 rather than 10067-28-4; the file's existing NIST WebBook citation (10067-28-4) is retained as the higher-authority source but this minor registry discrepancy is noted.
- No constituent-specific numeric dermal reference is available here.
- Some findings do not record an explicit exposure route; consult the linked study before applying them to a use.
