CONSTITUENT REPORT

beta-Himachalene

sesquiterpene hydrocarbonCAS 1461-03-6

beta-Himachalene is a cedar-associated sesquiterpene hydrocarbon best known as a major component of Himalayan and Atlas cedarwood oils and related himachalene-rich fractions. Compared with many archive constituents, it has a somewhat clearer experimental literature footprint, but much of that evidence still comes from whole-oil or fraction studies rather than isolated human-use research. For AromaForge, beta-himachalene is best framed as a cedarwood marker constituent with preclinical insecticidal and composition-focused evidence, not as a clinically established active.

Chemical identity and composition

NIST and The Good Scents Company list beta-himachalene under CAS 1461-03-6 and connect it to the broader himachalene sesquiterpene family. The local archive currently includes gamma-himachalene in hiba wood oil; beta-himachalene is more strongly documented in Cedrus oils than in the current local oil set.

Aroma and practical use

woodycedar-likedryresinousresin
  • Use the recorded woody, cedar-like, dry, resinous, resin 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.

cedarwood fraction insecticidal activity

A PubMed-indexed study on Himalayan cedarwood oil reported insecticidal activity across chromatographic fractions; one active fraction yielded beta-himachalene at 31% of essential-oil weight after purification, linking the constituent to an insecticidal cedarwood fraction.

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

diamondback moth oil activity

A PubMed abstract reported Cedrus deodara oil containing beta-himachalene at 45.8% and found measurable toxicity, repellence, and growth inhibition against diamondback moth larvae, again as whole-oil rather than isolated-constituent evidence.

Use concerns and concentration limits

Sensitization concernNot flagged

Not flagged in the current model. This is not proof of absence or unrestricted safety.

Phototoxicity concernNot flagged

Not flagged in the current model. This is not proof of absence or unrestricted safety.

Oxidation concernNot flagged

Not flagged in the current model. This is not proof of absence or unrestricted safety.

Penetration enhancementNot flagged

Not flagged in the current model. This is not proof of absence or unrestricted safety.

No numeric constituent-specific use limit is available here. Missing is not an unrestricted-use clearance.

No constituent-specific human clinical safety study or verified dermal limit for isolated beta-himachalene was found 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.

Because the published evidence is dominated by cedarwood fractions and insecticidal testing, beta-himachalene should not be framed as independently established for topical wellness use.

How the effects were investigated

terpene synthase product

A characterized bacterial terpene synthase has been described as a multiproduct beta-himachalene synthase, supporting a biosynthetic mechanism for beta-himachalene formation from terpene cyclization.

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 (7)
  • Much of the accessible bioactivity literature is on cedarwood oils or fractions, not purified beta-himachalene.
  • No verified human-use clinical evidence for isolated beta-himachalene was found in this pass.
  • The current local oil archive offers indirect himachalene-family context, but not a direct beta-himachalene constituent mapping in an existing oil file.
  • No IFRA Standard, Tisserand monograph, RIFM assessment, or peer-reviewed dermal-safety study specific to beta-Himachalene (CAS 1461-03-6) was located; PubChem (CID 11586487) and PubChem/GHS-style aggregator pages confirm identity only, without a verified human safety monograph. sensitizing:true has been corrected to null (unsupported guess) pending real citation.
  • No constituent-specific numeric dermal reference is available here.
  • 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.
