p-Mentha-1,3,8-triene is a lesser-known monoterpene hydrocarbon most often encountered as a compositional marker in parsley herb, parsley shoots, and related aromatic-herb oils rather than as a widely studied isolate. The strongest live evidence supports its identity, odor profile, and repeated occurrence in parsley-type oils, while constituent-specific pharmacology and safety data remain sparse. For AromaForge, it is most accurate to present p-mentha-1,3,8-triene as an herbaceous-terpenic identity marker with clear research gaps around isolated effects.
Chemical identity and composition
PubChem lists p-mentha-1,3,8-triene as CID 176983 with formula C10H14 and IUPAC name 1-methyl-4-prop-1-en-2-ylcyclohexa-1,3-diene. NIST search results confirm CAS 18368-95-1 and the common synonym 1,3,8-p-menthatriene. Within the AromaForge archive, parsley herb oil already uses this constituent as a notable component, citing 6.2% in a typical parsley herb analysis and 7.9-14.9% in a public Petroselinum crispum leaf-oil study.
Aroma and practical use
- Use the recorded terpenic, camphoreous, herbal, woody, pine, camphoraceous, herbaceous, piney 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 2017 herb-oil comparison study reported parsley shoot essential oil with 1,3,8-p-menthatriene at 38.4% to 48.8%, supporting its role as a major compositional marker in some parsley chemotypes.

Public parsley herb and parsley leaf references cited in the archive place p-mentha-1,3,8-triene around 6.2% in a typical parsley herb analysis and 7.9% to 14.9% in a Petroselinum crispum leaf-oil study.

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 concernFlagged
Flagged in the constituent reference; assess the source, route and finished-product concentration.
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.
No authoritative constituent-specific IFRA standard, ECHA harmonized classification page, or human tolerance study was located for isolated p-mentha-1,3,8-triene in this pass.
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.
Because the accessible evidence is heavily occurrence- and odor-focused, consumer copy should avoid implying specific physiological benefits for the isolated constituent.

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
no strong isolated mechanism located
No strong constituent-specific mechanism paper was located for isolated p-mentha-1,3,8-triene during this research pass; most evidence is identity and occurrence data.

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)
- No convincing isolated pharmacology literature was located for p-mentha-1,3,8-triene.
- No public constituent-specific safety monograph or dermal restriction was found during this pass.
- The available evidence is strong for identity and occurrence but weak for mechanism, toxicology, and human relevance.
- 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.
