Dihydrocarvone is a carvone-related monoterpene ketone most often encountered as a minor spearmint constituent and flavor-fragrance ingredient. The live evidence base is strongest for identity, occurrence in mint oils, organoleptic use, and fragrance safety review, with additional preclinical literature describing insecticidal and membrane-level bioactivity. For AromaForge, it is most accurately framed as a mint-chemistry and aroma marker with some preclinical mechanistic data rather than a human health ingredient with established clinical outcomes.
Chemical identity and composition
PubChem maps the broad name dihydrocarvone to 1,6-dihydrocarvone (CID 24473), while NIST and oil literature also distinguish cis and trans stereoisomers. In the archive, spearmint records use the broader constituent id for modest support fractions and separate cis-specific naming at the oil level when the source does so.
Aroma and practical use
- Use the recorded minty, herbal, spearmint-like, woody, camphoreous, herbaceous, camphoraceous 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.
house dust mite acaricidal activity
In a mite-control study, dihydrocarvone showed stronger contact and fumigant toxicity than benzyl benzoate, with reported LD50 values below the comparator in both house-dust-mite species.
Measured: acaricidal potency versus benzyl benzoate
This experimental finding does not establish benefit, dose or safety in people using this blend.
stored product insect bioactivity
A grain-pest study found that dihydrocarvone had measurable contact and fumigant toxicity and reduced egg hatching and later survival in Tribolium castaneum, although it ranked below the two carvone enantiomers.
Measured: toxicity ranking and egg-hatch suppression
This experimental finding does not establish benefit, dose or safety in people using this blend.

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 attachedA 2019 RIFM fragrance ingredient safety assessment exists for p-menth-8-en-2-one (CAS 7764-50-3), supporting that this constituent has been formally reviewed in fragrance-safety literature.
The source assessment applies to its specified exposure and preparation; this entry is not an unrestricted-use clearance.
The Good Scents page reviewed in this pass reports flavor-fragrance use and an IFRA-linked recommendation up to 10% in fragrance concentrate for the dextro-dihydrocarvone material listing.
This reference does not establish a therapeutic result or a safe use level for a custom oil blend.
The constituent-specific research located here did not establish human topical efficacy or broad standalone toxicology detail beyond fragrance-review context, so benefit and safety copy should stay conservative.
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.
How the effects were investigated
membrane interaction in model phospholipid films
A langmuir-film study reported that dihydrocarvone expanded DPPC monolayers, increased membrane elasticity, and likely altered membrane mechanics in ways that could influence nearby receptor function.
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 (5)
- The literature reviewed here distinguishes several stereoisomeric forms of dihydrocarvone, while many commercial and database records also use the broader unspecific name.
- No constituent-specific human clinical literature was verified in this pass.
- Most direct bioactivity papers located for isolated dihydrocarvone are agricultural or mechanistic rather than dermatologic or inhalation-use studies.
- 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.
