A LITTLE CARE GOES A LONG WAY

Using it thoughtfully

Read the full safety context before bringing this oil into your routine.

Cited dermal maximum · leave-on: 0.8%
Phototoxicity: Not flagged in this profile
Oxidation risk: medium

A cited maximum is a limit, not a suggested dilution. Missing restrictions do not establish safety.

No phototoxic restriction was identified in the reviewed source set for Ylang Ylang II. The main safety concern is sensitization rather than furocoumarin phototoxicity.

Contraindications & cautions

moderatePublic ylang-ylang safety guidance flags sensitization risk and gives a 0.8% maximum for skin application.

10 constituents

An oil's character comes from its natural chemical composition. Explore each constituent to understand the connections.

About this composition

This grade-II record is anchored to a public Naturkosmos allergen declaration with explicit percentages for the main declared aroma allergens and composition markers, plus two public technical sheets that identify Ylang Ylang II as the 6-8 hour distillation fraction from flowers. The public source set is weaker than a full GC/MS chromatogram, so the constituent list here is intentionally conservative and limited to compounds with exact published percentages in the reviewed documents.

A TRADITION OF BOTANICAL CURIOSITY

Traditional & reported uses

These uses reflect the profile's reported traditions and literature. They are not established treatment recommendations.

reported to support restful sleep and easing of occasional stress
traditionally associated with supporting feelings of romance in ritual use
used in perfumery as a heavier, more sesquiterpene-rich floral base-heart note
reported to support a sense of calm during moments of nervous tension

What we're still learning · 4 data gaps

Good decisions start with knowing what is — and isn't — in the evidence.

No public full GC/MS chromatogram for the exact reviewed Ylang Ylang II batch was verified in this pass; the missing source type is a batch-level GC/MS or peer-reviewed grade-II composition table with exact percentages for non-allergen major constituents such as germacrene D and alpha-farnesene.
odor_intensity 78 is an archive normalization from public qualitative odor statements ('floral, jasmined' and 'note florale de fond fleurie, douce') rather than a source-native 0-100 measurement.
Closure remains at 50.0% after a targeted re-check in this pass: a Laboratoire Helpac Grade II technical sheet (https://www.laboratoire-helpac.com/wp-content/uploads/2023/10/HEB185V_HE-YLANG-YLANG-GRADE-II.pdf) confirms germacrene D, beta-caryophyllene, geranyl acetate, and alpha-farnesene as principal components but publishes no percentages; an Arogreen spec sheet's chromatographic table is blank; no Shay and Company GC/MS lot report exists for grade II (only grade III); and several guessed supplier GC-MS URLs (NHR, Florihana, Eden Botanicals) returned no content. Sibling grade files (ylang-ylang-iii, ylang-ylang-fine) confirm germacrene D and alpha-farnesene are major in nearby cuts, but their exact percentages are grade-specific and cannot be substituted for grade II without inventing numbers, so no additional rows were added this pass.
Follow-up research pass (2026-07-09): re-searched for grade-II-specific GC/MS percentage data (distillation-time/fraction studies, supplier GCMS batch reports on Eden Botanicals/Florihana/Mountain Rose Herbs). Located one promising paper -- 'Comprehensive Characterisation of Ylang-Ylang Essential Oils According to Distillation Time, Origin, and Chemical Composition' (ScienceDirect S0021967320300054 / ResearchGate 338479564) -- which studies fractions by distillation time (directly analogous to commercial grading), but the ResearchGate mirror URL exceeded the fetch tool's URL-length limit and the ScienceDirect abstract page did not expose numeric percentages for individual fractions in the accessible preview. No new percentage rows were added to avoid fabricating grade-specific numbers; sibling grade files (ylang-ylang-i, ylang-ylang-iii, ylang-ylang-fine, ylang-ylang-extra) confirm germacrene D (11-18%) and alpha-farnesene (3-11%) are consistently major across nearby grades, but exact grade-II values cannot be safely interpolated without a source. Closure remains 0.500. Reaching >=0.95 requires either the full text of the distillation-time paper above or a readable grade-II-specific supplier GC-MS batch report, neither of which was accessible in this or the prior research pass.
