2,2,6-Trimethylcyclohexanone is a minor ketonic aroma constituent best documented in fragrance, flavor, and botanical volatile analysis rather than in direct human pharmacology. Archive-ready evidence supports it as a chemically defined alicyclic ketone found in cistus-related materials and in some food aroma systems, where studies describe it as a contributor to floral-fruity or rockrose-like odor character. The present evidence base is useful for identity, occurrence, odor role, and high-level safety-assessment tracking, but it is thin for mechanism or wellness-style claims and should be labeled accordingly.

Chemical identity and composition

PubChem lists CID 17000, molecular formula C9H16O, and IUPAC name 2,2,6-trimethylcyclohexan-1-one. Synonym sets also include 2,6,6-trimethylcyclohexanone and the perfumery-facing name cistus cyclohexanone.

Aroma and practical use

floral-fruitywoody-amberyrockrose-liketea-like
  • Use the recorded floral-fruity, woody-ambery, rockrose-like, tea-like 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.

A 2025 Foods study on floral-fruity Pu-erh tea identified 2,2,6-trimethylcyclohexanone among ten key active-aroma compounds, and the aroma recombination and omission workflow supported its contribution to the characteristic profile.

A 2025 review on Cistus ladanifer essential oils and volatiles supports cistus materials as a documented occurrence context for this constituent, although alpha-pinene and viridiflorol dominate the broader profile.

Recorded dermal reference1%

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 attached
A dedicated RIFM fragrance ingredient safety assessment exists for this constituent, which is useful as a safety anchor, but the accessible abstract did not expose a numeric dermal threshold or a concise hazard conclusion that could be transcribed responsibly here.
safety reviewRoute not recorded

The source assessment applies to its specified exposure and preparation; this entry is not an unrestricted-use clearance.

No archive-safe constituent-level medical or topical-use claim should be made from the currently retrieved evidence; safety handling should stay in fragrance-ingredient and research-material territory unless fuller toxicology documents are reviewed.

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)
  • Direct pharmacology or mechanism literature specific to 2,2,6-trimethylcyclohexanone was not located in this pass beyond aroma-role and safety-assessment references.
  • The accessible RIFM abstract did not expose the detailed toxicology conclusion, so no numeric dermal cap or hazard class is asserted here.
  • Most usable evidence is odor-function or occurrence data, not human outcome data.
  • 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.
