Petroselinic acid is a distinctive monounsaturated fatty acid concentrated in Apiaceae seed oils and is the dominant lipid marker in the archive's carrot-seed-oil record. Compared with typical volatile aroma constituents, its evidence base is more chemistry and formulation oriented: the strongest live sources cover identity, botanical abundance, skin-permeation behavior, and recent antifungal screening rather than fragrance odor impact. For AromaForge it is best presented as a fixed-oil composition marker with emerging preclinical activity data and practical formulation relevance, not as a clinically established topical active.
Aroma and practical use
- Use the recorded fatty, oily, soft, waxy 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 1998 skin-permeation paper reported that high-purity petroselinic acid enhanced indomethacin delivery through rat skin more strongly than oleic acid under the tested conditions and was effective even after transient enhancer treatment.

This experimental finding does not establish benefit, dose or safety in people using this blend.
A 2024 Phytomedicine paper reported that petroselinic acid inhibited growth, hyphae, and biofilm formation of pathogenic fungi, showed synergy with fluconazole, and retained antifungal effects in Galleria mellonella and murine candidiasis models while appearing less toxic to mammalian cells.

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 attachedCIR's 2017 plant-derived fatty-acid-oils assessment concluded that 244 plant-derived fatty acid oils are safe as used in cosmetics, which supports broad fixed-oil safety context but does not function as a constituent-specific therapeutic endorsement.
The source assessment applies to its specified exposure and preparation; this entry is not an unrestricted-use clearance.
Like other unsaturated fatty acids, petroselinic acid should be handled with normal oxidation-stability caution in storage and formulation, even though a dedicated constituent-specific modern dermal cap was not verified in this pass.
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
Rat-skin permeation work attributed petroselinic acid's enhancer effect to its interaction with stratum corneum lipids, supporting membrane-fluidization or barrier-disordering behavior as a formulation mechanism.

The 2024 antifungal study identified fructose-1,6-bisphosphate aldolase (Fba1p) as a target associated with petroselinic acid's antifungal effect in Candida models.

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 human topical or oral outcome studies on isolated petroselinic acid were not verified in this pass; most accessible literature is review, chemistry, or preclinical screening oriented.
- The local carrot-seed-oil record currently assigns CAS 112-80-1 to petroselinic acid, but live PubChem identity data support CAS 593-39-5 for the cis isomer used here.
- No modern constituent-specific leave-on dermal limit or inhalation-use framework was verified for isolated petroselinic acid.
- 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.
