trans-Pinene hydrate is a comparatively obscure monoterpene alcohol that appears mainly as a GC-identified minor-to-moderate constituent in selected essential oils rather than as a widely studied standalone fragrance molecule. The strongest evidence located here supports identity, occurrence, and nomenclature, while direct constituent-specific pharmacology and safety data are sparse. For AromaForge, it is best handled as a composition marker with an explicit evidence gap rather than as a wellness-forward active.
Chemical identity and composition
Current public identity sources are somewhat messy for this constituent. NIST lists trans-pinene hydrate under trans-2-pinanol with CAS 4948-29-2, while The Good Scents Company uses a trans-pinene hydrate entry with CAS 35408-04-9 and a different stereochemical rendering, and PubChem maps the name trans-pinene hydrate onto CID 6428289 with cis-2-pinanol as the title but includes trans-pinene hydrate among synonyms. The archived Leleshwa oil file currently carries CAS 1686-20-0, but that CAS is associated in PubChem and NIST indexing with p-mentha-1,5-dien-8-ol rather than the pinanol structure, so the archive should treat that oil-level CAS as unresolved context, not as a settled constituent identity.
Aroma and practical use
- Use the recorded camphoraceous, terpenic, woody, minty 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 Tarchonanthus camphoratus essential-oil paper identified trans-pinene hydrate at 8.8% among the principal constituents, supporting its occurrence in Leleshwa/camphor bush chemistry.

This reference does not establish a therapeutic result or a safe use level for a custom oil blend.
An earlier Food Chemistry study on Tarchonanthus camphoratus reported trans-pinene hydrate at 6.51% alongside other oxygenated monoterpenes, showing that the constituent recurs across independent camphor-bush profiles.

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.
A recorded constituent reference, not a recommended oil dilution. Product category, source applicability and all contributing oils must be checked before use.
unverified reference · No source provenance attachedThe Good Scents Company entry for trans-pinene hydrate states not for fragrance use and not for flavor use, but it does not provide a transparent toxicological rationale or exposure threshold on the indexed page.
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, sensitization, or clinical tolerability study for isolated trans-pinene hydrate was verified in this pass.

Because direct pharmacology evidence is sparse and nomenclature is inconsistent across public databases, benefit-oriented copy should stay especially conservative for this constituent.

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)
- Public identity databases do not cleanly agree on the stereochemical mapping and CAS for the name trans-pinene hydrate.
- No human clinical efficacy or tolerability study specific to isolated trans-pinene hydrate was verified in this pass.
- No robust constituent-specific pharmacology dataset was located beyond occurrence context and indirect oil-level reports.
- The numeric dermal reference lacks source provenance; a verified flag alone is insufficient.
- Some findings do not record an explicit exposure route; consult the linked study before applying them to a use.
