Isomenthone is a minty monoterpene ketone that recurs across AromaForge mint and geranium records, especially cornmint, peppermint, and rose-geranium profiles. The live evidence base is mixed in character: identity and archive-occurrence data are straightforward, but direct constituent-level bioactivity studies are limited and mostly preclinical. The strongest source-grounded themes are its role as a recurring chemotaxonomic and authenticity marker in mint-type oils, a cell-study signal for blocking TNF-alpha-driven fibroblast death through JNK and p38 MAPK pathways, and a weaker animal signal for slight choleretic effects compared with menthol and limonene.
Chemical identity and composition
PubChem identifies the reviewed record as C10H18O with InChIKey NFLGAXVYCFJBMK-IUCAKERBSA-N, while NIST lists the cis isomer under CAS 491-07-6. Local oil records consistently place isomenthone as a secondary-to-major component in mint and geranium materials, including 2.71% typical in redistilled cornmint, 3.666% in one cornmint COA, about 5% as the midpoint of the peppermint ISO range, and 6.5% in one geranium GC/MS lot.
Aroma and practical use
- Use the recorded minty, cool, peppermint-like, sweet descriptors to explore a blend's scent character; perceived strength also depends on the other ingredients.
- Compare the recorded goal signals with the intended purpose, while keeping model assumptions separate from observed study outcomes.
- 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 2012 human-dermal-fibroblast study found that isomenthone inhibited TNF-alpha-mediated loss of cell viability, reduced apoptosis, and blocked JNK and p38 MAPK signaling under serum-free stress conditions.
This is the strongest direct constituent-level mechanism study found in this pass, but it remains a cell model and does not establish a clinical topical benefit.
This experimental finding does not establish benefit, dose or safety in people using this blend.
A 2015 rat study testing five Danshu-capsule constituents reported that isomenthone showed only slight choleretic effects, while menthol and limonene were the main contributors to bile-related outcomes.
The abstract explicitly describes isomenthone as a menthone isomer with slight choleretic activity rather than a dominant effect driver.
This experimental finding does not establish benefit, dose or safety in people using this blend.
A mouse behavioral study identified isomenthone among peppermint-oil constituents that significantly increased ambulatory activity after intraperitoneal and lower-dose intravenous administration.
This is a whole-behavior animal result and should be framed cautiously because it does not translate directly into human aroma outcomes.
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 attachedNo constituent-specific IFRA dermal limit or similarly clear public aroma-use restriction for isolated isomenthone was verified 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.
The strongest benefit-oriented findings reviewed here are cell and animal studies, so archive copy should avoid implying established human efficacy.
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.
An Australian government tier-II assessment treats menthone and isomenthone together as industrial chemicals and does not provide a constituent-specific aromatherapy-use benefit claim basis.
The source assessment applies to its specified exposure and preparation; this entry is not an unrestricted-use clearance.

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
suppression of JNK and p38 MAPK activation under TNF-alpha stress
The fibroblast study links isomenthone to reduced activation of stress-kinase pathways and downstream apoptotic events in a serum-free TNF-alpha challenge model.
This experimental finding does not establish benefit, dose or safety in people using this blend.
minor contribution to choleretic activity in a multicomponent mint-like formula model
The rat bile-secretion study suggests isomenthone contributes only slightly to the observed effect profile and is not the main driver among the tested monoterpenes.
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)
- Direct human studies on isolated isomenthone are scarce; most accessible papers are in vitro, animal, or oil-mixture context.
- Recent literature often treats isomenthone as an authenticity or composition marker rather than a standalone bioactive constituent.
- A verified constituent-specific dermal or sensitization limit was not found in the reviewed sources.
- 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.
