Daucol is a carrot-associated oxygenated sesquiterpene that appears regularly in carrot seed oil and related Daucus carota extracts, but its direct evidence base is still sparse. Live sources support its identity and archive relevance clearly, while the accessible biological literature is mostly limited to antifungal screening in agricultural models where daucol was tested alongside carotol and daucene. For AromaForge, daucol is best framed as a secondary carrot-seed marker with limited preclinical activity data and explicit safety and human-evidence gaps.
Chemical identity and composition
PubChem identifies daucol as C15H26O2 and lists multiple stereochemical synonyms that place it in the daucane/carotane sesquiterpene family. Public registry data vary: PubChem synonyms include both 887-08-1 and 14089-49-7, and the existing archive carrot-seed oil record currently uses 14089-49-7. This entry follows the public synonym set that includes 887-08-1 while noting that CAS normalization remains a cleanup item. In the archive, daucol is notable in cold-pressed carrot seed oil at 12.60%, supporting it as a meaningful carrot constituent rather than a trace impurity.
Aroma and practical use
- Use the recorded earthy, woody, dry, carrot-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 2004 antifungal paper on carrot seed oil and its major sesquiterpenes tested daucol against Alternaria alternata and reported that carotol was the strongest constituent in the assay, implying daucol was less active under the same conditions.
This is direct constituent-level testing for daucol, but the study supports moderate or secondary activity rather than a standout effect.
This experimental finding does not establish benefit, dose or safety in people using this blend.
A 2019 carrot seed constituent paper isolated daucol alongside daucene and carotol and reported dose-dependent in vitro antifungal testing against three rice phytopathogens, with stronger overall performance assigned to carrot seed methanol extract and carotol.
This reinforces daucol as an actively tested constituent in agricultural antifungal research, while also showing the current evidence is weaker than for carotol.
This experimental finding does not establish benefit, dose or safety in people using this blend.
Use concerns and concentration limits
Sensitization concernNot flagged

No numeric constituent-specific use limit is available here. Missing is not an unrestricted-use clearance.
The reviewed public references did not establish a constituent-specific dermal maximum, IFRA limit, or human safety study for isolated daucol.
This reference does not establish a therapeutic result or a safe use level for a custom oil blend.
Public chemistry listings reviewed in this pass include no determined oral, dermal, or inhalation toxicity values for daucol.
This reference does not establish a therapeutic result or a safe use level for a custom oil blend.
Because daucol evidence is limited to occurrence and early in vitro screening, archive summaries should avoid translating these results into treatment-style claims.
This reference does not establish a therapeutic result or a safe use level for a custom oil blend.
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
fungal_growth_inhibition_in_screening_assays
Published daucol data support a measurable in vitro antifungal effect in comparative plant-pathogen assays, but no validated molecular target or human-use mechanism was established in the reviewed sources.
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 (6)
- No human clinical study specific to isolated daucol was verified in this pass.
- Public constituent-specific toxicology for daucol is sparse and the CAS registry picture is inconsistent across sources.
- The direct activity evidence is limited to agricultural in vitro assays rather than broader pharmacology or human-use research.
- Worker c8 search (2026-07-13): no IFRA/RIFM or peer-reviewed dermal safety data specific to daucol (CAS 887-08-1) located beyond supplier identity listings and one phytochemistry paper. Prior dermal_limit_pct:20 and sensitizing:true were unsupported placeholders and have been corrected to null/false.
- 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.
