Camphene hydrate is an oxygenated monoterpene alcohol that appears intermittently in conifer, citrus, and specialty wood or leaf volatile profiles, and it is already represented in the AromaForge archive through ho-sho leaf and related analytical records. The current public evidence base is thin: live sources strongly support identity and repeated GC-MS occurrence, but this research pass did not verify a substantial constituent-specific pharmacology or human safety literature. Archive use should therefore emphasize chemistry, occurrence, and honest evidence gaps rather than benefit-forward claims.
Chemical identity and composition
PubChem identifies camphene hydrate as C10H18O with the name 2,3,3-trimethylbicyclo[2.2.1]heptan-2-ol. NIST provides a dedicated 2-exo-camphene hydrate entry with the same formula, while The Good Scents Company lists CAS 465-31-6 and notes it as a natural-substances-and-extractives material with no fragrance or flavor use recommendation shown on the page reviewed in this pass.
Aroma and practical use
- Use the recorded camphoraceous, woody, cooling, terpenic descriptors to explore a blend's scent character; perceived strength also depends on the other ingredients.
- 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 2023 Norway spruce hydrosol study reported that camphene hydrate was the only compound detected in all 32 hydrosol samples analyzed.
This is useful archive evidence that camphene hydrate can behave as a recurring hydrosol marker even when it is not among the best-studied terpene constituents.
This reference does not establish a therapeutic result or a safe use level for a custom oil blend.
A 2021 white fir foliar essential-oil paper quantified camphene hydrate at 0.6-0.7% in two analyzed Abies concolor samples.
The paper strengthens constituent-level occurrence evidence in conifer oils and supports use of camphene hydrate as a minor but stable analytical marker.
This reference does not establish a therapeutic result or a safe use level for a custom oil blend.
The archive's ho-sho leaf oil record is anchored to a public study that reports camphene hydrate at 1.5% in one analyzed profile.
This directly supports AromaForge relevance even though it is occurrence data rather than an activity paper.
This reference does not establish a therapeutic result or a safe use level for a custom oil blend.
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.
The Good Scents page reviewed in this pass lists no published fragrance-use or flavor-use recommendation for camphene hydrate.
This reference does not establish a therapeutic result or a safe use level for a custom oil blend.
No constituent-specific IFRA limit, human exposure study, or dedicated dermal-sensitization paper for isolated camphene hydrate was verified in this pass.
This reference does not establish a therapeutic result or a safe use level for a custom oil blend.
Because the accessible literature is mostly analytical rather than biological, archive copy should avoid implying established functional benefits for isolated camphene hydrate.
This reference does not establish a therapeutic result or a safe use level for a custom oil blend.
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 convincing human clinical literature for isolated camphene hydrate was verified in this pass.
- Direct constituent-specific pharmacology appears far weaker than the occurrence literature and may be absent in the public record.
- Constituent-specific dermal, inhalation, and repeated-dose safety data for isolated camphene hydrate were not located in the reviewed public sources.
- A c6 verification search (2026-07-13) found only sensitization/NESIL data for parent camphene (CAS 79-92-5), not the hydrate (CAS 465-31-6); no RIFM/IFRA assessment specific to camphene hydrate exists, so the prior unsourced 20% dermal_limit_pct and sensitizing:true were corrected to null.
- 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.
