beta-Phenylethyl tiglate is an aromatic tiglate ester used in fragrance and flavor work and also reported as a minor natural constituent in some essential oils, including geranium materials already represented in the AromaForge archive. The strongest source-grounded evidence here is identity and occurrence data: NIST and PubChem define the compound, local archive oil records place it in Chinese geranium, and open composition studies also report it in immortelle and geranium-related materials. A published RIFM fragrance safety assessment exists, but directly readable public mechanistic or human-use findings specific to the isolated constituent were limited in this pass, so performance and wellness framing should stay focused on odor character and occurrence rather than health effects.
Chemical identity and composition
PubChem and NIST describe beta-phenylethyl tiglate as 2-phenylethyl (E)-2-methylbut-2-enoate with formula C13H16O2 and InChIKey KVMWYGAYARXPOL-QDEBKDIKSA-N. It is a tiglic-acid ester of phenethyl alcohol rather than a terpene hydrocarbon or alcohol, which helps explain its floral-green odor profile and its appearance in ester-rich floral materials.
Aroma and practical use
- Use the recorded green, rosy, leafy, wine-like, rose-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.
immortelle occurrence
A PubMed-listed abstract on immortelle composition reported that among Croatian populations, three dominant essential-oil components included alpha-pinene, geranyl acetate, and 2-phenylethyl tiglate, supporting natural occurrence of this ester in some aromatic plant chemotypes.
Measured: constituent occurrence among dominant oil components
This reference does not establish a therapeutic result or a safe use level for a custom oil blend.
geranium occurrence
An open geranium composition PDF snippet reported 2-phenylethyl tiglate at 1.5% in a Pelargonium graveolens sample, which aligns with the archive's lower but comparable Chinese geranium occurrence range.
Measured: relative abundance in geranium oil

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 published RIFM fragrance ingredient safety assessment exists for phenethyl tiglate, which supports treating this material as a recognized fragrance-safety subject rather than an uncatalogued minor chemical.
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.
No constituent-specific public IFRA leave-on limit, phototoxic warning, or directly readable human clinical benefit literature was located in this review pass.
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.
Because the accessible evidence was dominated by identity, odor, and occurrence sources, broader health or mechanism claims would overstate the current source base.

Constituents it may interact with
No constituent-pair interaction is recorded for this identity. The report does not assume either amplification or incompatibility.
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 directly readable public human studies focused on isolated beta-phenylethyl tiglate were located in this pass.
- No strong mechanistic pharmacology literature specific to the isolated constituent was located in accessible sources reviewed here.
- The available evidence is much stronger for identity, odor, and occurrence than for topical safety thresholds or biological activity.
- Safety-verification pass (2026-07-13, worker c5): the RIFM fragrance ingredient safety assessment for phenethyl tiglate (CAS 55719-85-2, Food and Chemical Toxicology, PMID 29305930) concludes skin sensitization shows no safety concern at current declared use levels, corroborating sensitizing:false. No IFRA Standard numeric leave-on limit was located in this pass, so the prior uncited dermal_limit_pct of 0.1 has been corrected to null.
- 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.
