Arachidic acid is a long-chain saturated fatty acid better known as eicosanoic acid than as a fragrance-active aromatic constituent. In the AromaForge archive it appears mainly in carrier or fixed oils rather than classic volatile essential-oil profiles, which fits the literature: public evidence is strongest for identity, occurrence in lipid matrices, and cosmetic ingredient status. Direct constituent-specific bioactivity literature is thin and context-dependent, so archive copy should frame arachidic acid primarily as a compositional fatty-acid marker with clear evidence gaps around standalone wellness relevance.
Chemical identity and composition
PubChem lists arachidic acid as CID 10467 with formula C20H40O2 and IUPAC name icosanoic acid. Within the archive it appears in fixed-oil style records such as camellia seed oil at 0.29% in one COA and in moringa oil context as a minor long-chain saturated fatty acid family peer, reinforcing that this constituent belongs more to lipid profiling than to volatile aroma chemistry.
Aroma and practical use
- Use the recorded fatty, waxy, low-odor 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 2012 Ficaria kochii composition study identified fatty-acid and essential-oil profiles but did not present arachidic acid as a dominant volatile constituent, underscoring that this molecule is usually a minor part of broader lipid mixtures.

This reference does not establish a therapeutic result or a safe use level for a custom oil blend.
A 2014 Euphorbia study reported arachidic acid as the main identified constituent of one species' essential-oil fraction, but the measured antioxidant activity was assigned to crude extracts and not to isolated arachidic acid.

This experimental finding does not establish benefit, dose or safety in people using this blend.
A 2015 Trifolium angustifolium paper listed arachidic acid at 15.5% of the essential oil composition, while antioxidant, anticholinesterase, and antimicrobial results were reported at the extract level rather than for isolated arachidic acid.

A rat feeding study used arachidic acid as a saturated-fatty-acid challenge and found increased liver-to-body-weight ratio and intrahepatic macrophage population under the study conditions, with those alterations mitigated by kojibiose co-feeding.

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 attachedThe Cosmetic Ingredient Review safety assessment for fatty acids and fatty acid salts concluded that the reviewed group, including arachidic acid, is safe in cosmetics in present practices of use and concentration when formulated to be non-irritating and non-sensitizing.
The source assessment applies to its specified exposure and preparation; this entry is not an unrestricted-use clearance.

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
lipid distribution matches long chain fatty acids
A rat metabolism paper cited by the CIR safety assessment reported that radiolabeled arachidic acid followed the same principal pathways as palmitic acid, although it disappeared more slowly from blood and showed a different esterification distribution in liver lipids.
This experimental finding does not establish benefit, dose or safety in people using this blend.
No direct public citation is attached to this entry.
no clear constituent specific target mechanism
No robust constituent-specific signaling mechanism or replicated standalone pharmacology for isolated arachidic acid was verified in this pass beyond its broad role as a long-chain saturated fatty acid within lipid metabolism.

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 constituent-specific human data for isolated arachidic acid were not verified in this pass.
- Most located biological activity papers measured extract-level outcomes or used arachidic acid as a metabolic challenge rather than demonstrating a clear standalone benefit.
- Public fragrance-focused sensory, dermal-limit, and aromatherapy literature for arachidic acid remains sparse.
- 2026-07-13 re-verification (worker c3): a targeted search for arachidic acid (CAS 506-30-9) dermal/sensitization/fragrance safety data returned only supplier identity pages; no constituent-specific numeric dermal limit located, dermal_limit_verified remains false.
- 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.
