p-Mentha-1,3-dien-7-al is a cumin-linked monoterpene aldehyde that appears in the AromaForge cumin record at meaningful levels rather than as a trace artifact. The strongest public evidence supports its identity, flavor-registration status, and repeated occurrence in cumin oil, while direct isolated pharmacology and dermal safety literature remain sparse. For archive use, it is most accurate to present p-mentha-1,3-dien-7-al as a compositional and sensory marker with limited constituent-specific bioactivity evidence.
Chemical identity and composition
PubChem identifies p-mentha-1,3-dien-7-al as C10H14O with InChIKey MKVBITWQDIIUMF-UHFFFAOYSA-N and IUPAC name 4-propan-2-ylcyclohexa-1,3-diene-1-carbaldehyde. FAO/JECFA lists CAS 1197-15-5, JECFA number 1906, FEMA 4506, and the chemical name 4-isopropylcyclohexa-1,3-dienecarbaldehyde. In the local archive it is a substantial cumin constituent at roughly 2.8-22% with a current typical record around 11.42%.
Aroma and practical use
- Use the recorded fatty, spicy, aldehydic, cumin-like 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 cumin essential-oil paper reported p-mentha-1,3-dien-7-al at 26.7% of the tested cumin oil, making it the major detected constituent in that sample and reinforcing its relevance as a real chemotype marker rather than a trivial trace component.

This reference does not establish a therapeutic result or a safe use level for a custom oil blend.
A 2022 Argentine cumin-oil study did not detect p-mentha-1,3-dien-7-al in its Catamarca sample and noted prior suggestions that this aldehyde can form during storage of ground seeds or during oil distillation, which is a useful caution about occurrence variability.

WHO/JECFA lists 1,3-p-menthadien-7-al as a flavouring agent with a 2010 evaluation of no safety concern at current levels of intake when used as a flavouring agent, which is useful oral flavor-use context but not a topical-use dossier.

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 assessed
Not assessed in the available record.
Penetration enhancementNot assessed
Not assessed in the available record.
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 clearest accessible safety context for p-mentha-1,3-dien-7-al comes from food-flavor evaluation rather than constituent-specific dermal, inhalation, or human aromatherapy studies.

FAO/JECFA records describe the material as a clear colourless liquid with fatty spicy aroma and note practical insolubility in water and solubility in ethanol, which is useful formulation context but not a hazard assessment by itself.

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)
- No strong isolated constituent pharmacology study was verified for p-mentha-1,3-dien-7-al in this pass.
- Public evidence is materially stronger for identity, cumin occurrence, and flavor-use status than for direct mechanism or efficacy claims.
- This pass did not verify a constituent-specific dermal exposure limit, sensitization dataset, or human inhalation study.
- 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.
