Tricosane is a straight-chain C23 alkane that appears in some floral oils and wax-rich aromatic materials more as a heavy hydrocarbon marker than as an odor-dominant terpene. The live evidence base is strongest for identity, physical chemistry, and ecological roles as a cuticular hydrocarbon in insects, with much weaker direct human-use or aromatherapy-style evidence. For AromaForge, tricosane is best presented as a waxy compositional constituent with semiochemical and cuticle-related research context, alongside clear safety and efficacy gaps.
Chemical identity and composition
NIST and PubChem both identify tricosane as C23H48, a straight-chain saturated hydrocarbon also named n-tricosane. HMDB describes it as a very hydrophobic alkane and notes plant-food occurrence context. In the local archive, tricosane appears in Moldovan pink musk rose otto / Rosa gallica at 5.3% and in Chinese Kushui rose standards at 0.6-2.0%, which fits its role as a heavier hydrocarbon component of some rose profiles rather than a high-impact top note.
Aroma and practical use
- Use the recorded waxy, faint, oily, paraffinic 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 2018 Drosophila suzukii study reported that tricosane (n-C23), when tested among major cuticular hydrocarbons, negatively regulated courtship and mating when normal hydrocarbon ratios were disrupted.
The paper identifies tricosane as one of several 23-carbon cuticular hydrocarbons associated with sexually mature flies and shows behavioral effects in bioassays.
This experimental finding does not establish benefit, dose or safety in people using this blend.
A 2015 Cell Reports paper on Camponotus ants found that antennal sensilla broadly detect cuticular hydrocarbons, supporting the relevance of compounds such as tricosane within social-recognition chemistry.
The study is broader than tricosane alone, but it is a strong primary source for the functional context of straight-chain hydrocarbons in insect communication systems.
This experimental finding does not establish benefit, dose or safety in people using this blend.
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.
NOAA CAMEO characterizes tricosane as a mostly unreactive saturated aliphatic hydrocarbon that is insoluble in water and mainly incompatible with strong oxidizing agents.

Because tricosane is a heavy hydrocarbon with sparse human-use literature, benefit-facing copy should stay limited to composition and aroma context rather than physiology claims.

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
participation in cuticular hydrocarbon signaling and recognition systems
In insect models, tricosane functions as one of the hydrocarbons detectable by olfactory or contact-communication systems involved in social or mating behavior.
This experimental finding does not establish benefit, dose or safety in people using this blend.
hydrophobic barrier behavior typical of long-chain saturated hydrocarbons
This is a chemistry-grounded inference supported indirectly by HMDB's hydrophobic description and the broader cuticular-hydrocarbon literature rather than by a tricosane-only human formulation study.
This reference does not establish a therapeutic result or a safe use level for a custom oil 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)
- Direct human fragrance-safety, dermal, or inhalation data for isolated tricosane were not identified in the reviewed public sources.
- Most functional literature concerns insect cuticular hydrocarbons generally, not tricosane as a standalone therapeutic or cosmetic-active ingredient.
- The rose-occurrence evidence is useful but partly relies on standards or excerpt-level access rather than a large open constituent-specific literature.
- 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.
