Heptadecane is a straight-chain C17 alkane found in the AromaForge archive mainly as part of the waxy hydrocarbon fraction of rose otto profiles. The live evidence base is lighter on direct bioactivity than on identity and safety: NIST and PubChem clearly support registry identity, local oil records show repeated occurrence in rose oils, and a 2026 RIFM citation strengthens fragrance-safety coverage. Direct functional studies located here point mostly to insect olfactory or ecological activity rather than to any human wellness use, so the archive should position heptadecane primarily as a rose-profile hydrocarbon marker with limited standalone efficacy evidence.
Chemical identity and composition
NIST lists heptadecane as C17H36, CAS 629-78-7, with common names n-heptadecane and normal-heptadecane. In aromatic materials it is a long-chain saturated hydrocarbon associated more with waxy body and stearoptene character than with a strong top-note odor, which matches its recurring presence in rose-otto chemistry.
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 2022 PubMed snippet on plant volatile organic compounds attractive to Lygus pratensis reported a strong attractant effect of heptadecane on adults, with field trapping differences at tested concentrations.
This is useful evidence that isolated heptadecane can be behaviorally active, but it is ecological entomology rather than human-use science.
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.
A 2026 PubMed citation indicates that a dedicated RIFM fragrance ingredient safety assessment is available for heptadecane.
The source assessment applies to its specified exposure and preparation; this entry is not an unrestricted-use clearance.
No direct public citation is attached to this entry.
Contemporary supplier SDS documents consistently classify heptadecane with aspiration-hazard language if swallowed and enters airways, so consumer copy should avoid implying ingestion-like use.
The source assessment applies to its specified exposure and preparation; this entry is not an unrestricted-use clearance.
No direct public citation is attached to this entry.
Public evidence located here is stronger for identity and safety handling than for constituent-specific wellness or pharmacology claims.
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.
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
behaviorally_active_plant_volatile_for_insects
The Lygus pratensis study snippet supports heptadecane acting as an attractant volatile at tested concentrations in field-trapping work.
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 (7)
- No human clinical literature specific to isolated heptadecane was verified in this pass.
- Direct isolated-compound findings located here were ecological rather than wellness-oriented.
- The full text of the 2026 RIFM heptadecane assessment was not directly read in this pass, so safety language is kept conservative.
- 2026-07-13 verification pass: repeated attempts to fetch the full-text RIFM assessment (researchgate publication 403107726 and elsevier mirror) timed out or returned no readable content; no explicit numeric dermal limit could be confirmed, so the prior dermal_limit_pct (0.1) placeholder has been corrected to null pending full-text access.
- 2026-07-13 second-pass verification: fetched The Good Scents Company listing for heptadecane (CAS 629-78-7) directly (different source from the RIFM/researchgate angle already tried). Its Safety Information section lists Dermal and Inhalation Toxicity as 'Not determined' (with only an old intravenous-mouse LDLo behavioral-toxicity citation on file), and its Safety in Use Information section only gives a flavor-usage recommendation ('not for flavor use') with no fragrance usage level listed. This corroborates the absence of a public numeric dermal limit; dermal_limit_pct, sensitizing, and penetration_enhancer remain unverified.
- 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.
