Chrysanthenyl acetate is a bicyclic monoterpene ester that appears in mugwort, Anthemis, feverfew, and related Asteraceae volatile profiles. The current evidence base is uneven: identity and occurrence data are straightforward, and a small number of older and newer papers discuss prostaglandin-synthesis inhibition or antimicrobial/biofilm effects, but much of that context is indirect or mixture-linked. For AromaForge, it is best described as a chemotype and composition marker with interesting preclinical leads and explicit gaps around standalone safety and human relevance.
Chemical identity and composition
PubChem lists chrysanthenyl acetate as C12H18O2 with the IUPAC name (2,7,7-trimethyl-6-bicyclo[3.1.1]hept-2-enyl) acetate. Public literature uses cis-, trans-, and (E)- labels inconsistently, and some archive oil records or supplier references may attach different CAS numbers depending on isomer assignment. This record follows PubChem and PubMed-indexed chemical-list support for CAS 54324-99-1 while keeping the stereochemical ambiguity explicit.
Aroma and practical use
- Use the recorded green herbal, camphoraceous, fresh ester-like descriptors to explore a blend's scent character; perceived strength also depends on the other ingredients.
- Review the flagged use concerns across every contributing oil and the selected dilution.
- 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 1988 Journal of Pharmacy and Pharmacology study reported an IC50 of 14.2 microM for chrysanthenyl acetate in the in vitro inhibition of prostaglandin synthetase-mediated PGE2 production from arachidonic acid.
This is the clearest isolated-compound mechanistic result located in this pass, but it is an older enzyme assay and not a human-use study.
This experimental finding does not establish benefit, dose or safety in people using this blend.
A 2020 review centered on Anthemis secundiramea described a flower oil consisting essentially of (+)-(E)-chrysanthenyl acetate and summarized antibacterial, antibiofilm, and antioxidant-enzyme findings for that highly enriched flower-oil system.
The review is useful because the flower oil was unusually pure in chrysanthenyl acetate, but the activity claims still rest mostly on oil-level data rather than definitive isolated-compound dosing studies.
This experimental finding does not establish benefit, dose or safety in people using this blend.
A 2010 comparative analysis of six Anthemis taxa reported cis-chrysanthenyl acetate at 17.5-22.0% in Anthemis austriaca oils, supporting its status as a genuine chemotype-level constituent rather than a one-off trace detection.
This finding strengthens occurrence confidence and helps separate identity support from the much thinner mechanistic literature.
This reference does not establish a therapeutic result or a safe use level for a custom oil blend.
Use concerns and concentration limits
Sensitization concernFlagged
Flagged in the constituent reference; assess the source, route and finished-product concentration.
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.
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 authoritative constituent-specific IFRA restriction, RIFM safety monograph, or human dermal study for isolated chrysanthenyl acetate 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.
Because public bioactivity papers often rely on enriched flower oils or historical screening assays, safety interpretation should default to parent-oil context rather than standalone constituent certainty.

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
prostaglandin_synthetase_inhibition
An older feverfew paper measured in vitro inhibition of prostaglandin synthetase-mediated PGE2 production by chrysanthenyl acetate, suggesting a plausible inflammation-related enzyme target in preclinical systems.
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)
- Very little modern isolated-compound pharmacology was verified for chrysanthenyl acetate beyond an older prostaglandin-synthetase assay.
- Public safety data for isolated chrysanthenyl acetate are sparse, and no constituent-specific topical-use limit was found.
- CAS and stereochemical labeling vary across sources, so future curation may need to split cis/trans records if the archive adopts stricter isomer handling.
- 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.
