Isopinocamphone

monoterpene ketoneCAS 473-62-1

Isopinocamphone is a bicyclic monoterpene ketone most strongly associated with hyssop and related Lamiaceae oils, where it often appears alongside pinocamphone as a composition-defining constituent. Public identity data are strong, but the standalone evidence base is narrower than for more common terpenes: the best accessible studies concern hyssop chemotype occurrence, insect fumigant activity, and neurotoxicity cautions linked to hyssop oil. For AromaForge, isopinocamphone should be treated primarily as a hyssop chemistry marker with clear safety caveats and limited isolated-molecule pharmacology.

Chemical identity and composition

PubChem resolves isopinocamphone to CID 84532 with formula C10H16O and InChIKey MQPHVIPKLRXGDJ-RNJXMRFFSA-N, while NIST lists CAS 473-62-1 and a stereochemical pinanone-style naming family. Public synonym sets also expose the parallel cis-pinocamphone naming that appears in essential-oil literature. In the local archive, hyssop is explicitly typed as an isopinocamphone/pinocamphone chemotype, and a representative hyssop oil record lists isopinocamphone at 44.7%.

Aroma and practical use

camphoreouswoodyherbalsharpcamphoraceousherbaceous
  • Use the recorded camphoreous, woody, herbal, sharp, camphoraceous, herbaceous 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 2016 Molecules paper on rice weevil control reported that pinocamphone and isopinocamphone were isolated from hyssop oil and showed the strongest fumigant toxicity among the tested compounds against adult Sitophilus oryzae.

This is the clearest constituent-specific activity study located in this pass, but it concerns insecticidal rather than human-directed bioactivity.

This experimental finding does not establish benefit, dose or safety in people using this blend.

A 1979 animal toxicity study on sage and hyssop essences linked hyssop neurotoxicity to the terpene ketones pinocamphone and isopinocamphone, while stating that pinocamphone had the stronger convulsant profile.

This is an important safety-context source even though it addresses oils and terpene-ketone attribution rather than purified isopinocamphone alone.

A 2026 Plants review summarized hyssop essential oil as being rich in monoterpene ketones, especially isopinocamphone and pinocamphone, and noted that full bloom is associated with high essential-oil concentration.

This supports isopinocamphone's archive relevance as a major hyssop marker, though it is review-level rather than a new constituent-specific experiment.

Recorded dermal reference0.5%

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
The 1979 hyssop toxicity paper tied hyssop neurotoxicity to pinocamphone and isopinocamphone, which supports caution around high-isopinocamphone hyssop chemotypes.

This experimental finding does not establish benefit, dose or safety in people using this blend.

The Good Scents Company shows inconsistent commercial handling across isopinocamphone records, with one page surfacing a 2.0% fragrance-concentrate recommendation and another natural-substances page showing not-for-fragrance-use language; this should be treated as a signal that source harmonization is incomplete.

No constituent-specific human tolerability study, reproductive-toxicity dataset, or robust IFRA-style limit specifically validated for isolated isopinocamphone was verified in this pass.

How the effects were investigated

major_contributor_to_hyssop_fumigant_toxicity_against_rice_weevil

A 2016 Molecules study isolated pinocamphone and isopinocamphone from hyssop oil and identified isopinocamphone as one of the major contributors to fumigant toxicity against adult Sitophilus oryzae.

preclinicalRoute not recorded

This experimental finding does not establish benefit, dose or safety in people using this blend.

neurotoxicity_caution_in_hyssop_context

An older hyssop toxicity paper tied hyssop neurotoxicity to pinocamphone and isopinocamphone, supporting a cautionary mechanism narrative around convulsant terpene ketones even though the abstract singled out pinocamphone as the more potent convulsant.

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 (6)
  • Direct human clinical evidence for isolated isopinocamphone was not verified in this pass.
  • Much of the safety narrative is inferred from hyssop-oil and terpene-ketone context rather than purified isopinocamphone toxicology.
  • Commercial source records for isopinocamphone are not fully harmonized on CAS and use-level presentation, so future cleanup may need an isomer-normalization pass.
  • 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.
  • Interaction candidates lack an attached source citation and remain unqualified.
