Eremophilene is an eremophilane-type sesquiterpene hydrocarbon found in blue cypress and other botanical volatile profiles in the AromaForge archive. The current source base is stronger for identity, occurrence, and biosynthetic or agrochemical research than for human wellness evidence. Publicly accessible evidence does include a modern engineered-yeast study reporting insect-repelling activity for (-)-eremophilene, but that remains preclinical and application-specific, so the archive should frame eremophilene primarily as a chemistry marker with early functional signals rather than a validated therapeutic ingredient.
Chemical identity and composition
PubChem REST data identifies eremophilene as CID 12309744 with formula C15H24 and IUPAC name (3R,4aR,5S)-4a,5-dimethyl-3-prop-1-en-2-yl-2,3,4,5,6,7-hexahydro-1H-naphthalene. PubChem synonym data and The Good Scents Company both support CAS 10219-75-7 and the synonym eremophylene. In the AromaForge archive, blue cypress records place eremophilene at 3.38% of a public Callitris intratropica monograph profile.
Aroma and practical use
- Use the recorded woody, dry, herbaceous, sesquiterpenic 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.
occurrence in blue cypress
The reviewed Australian Botanical Products blue cypress monograph lists eremophilene at 3.38% among the principal sesquiterpenes of Callitris intratropica wood-and-bark oil.
Measured: principal constituent percentage
This reference does not establish a therapeutic result or a safe use level for a custom oil blend.
insect repellency research
The PubMed snippet for the 2022 Metabolic Engineering paper states that (-)-eremophilene repelled fall leafworm, positioning eremophilene as an early-stage agricultural or ecological research molecule.
Measured: repellency against fall leafworm
This experimental finding does not establish benefit, dose or safety in people using this 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 Company lists eremophilene as a natural substance and extractive and notes 'not for fragrance use' and 'not for flavor use,' but does not provide a transparent constituent-specific dermal limit.

Constituents it may interact with
No constituent-pair interaction is recorded for this identity. The report does not assume either amplification or incompatibility.
How the effects were investigated
insect repellent volatile signal
The accessible abstract literature links (-)-eremophilene to repellency against fall leafworm, suggesting a volatile ecological or pest-deterrent mechanism rather than a medical mechanism.
This experimental finding does not establish benefit, dose or safety in people using this blend.
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 human clinical studies specific to isolated eremophilene were located in the reviewed public sources.
- Direct constituent-specific anti-inflammatory, antimicrobial, or topical-use papers were not verified in this pass beyond ecological or engineering-context evidence.
- Constituent-specific dermal-limit, sensitization, and phototoxicity data were not located in the reviewed public sources.
- 2026-07-13 verification pass: web search for IFRA/RIFM dermal limit and sensitization data found no authoritative constituent-specific results; prior dermal_limit_pct (25) and sensitizing (true) were unsourced placeholders and have been 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.
