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
- 1.85%
- 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 flower-oil-specific phototoxic restriction was identified in the cited public sources. The reviewed public material describes a steam-distilled flower oil rather than a cold-pressed peel oil.
Contraindications & cautions
- moderatePomelo flower essential oil carries high natural farnesol (~15.7%) plus linalool and limonene, all regulated fragrance allergens; individuals with known fragrance/allergen sensitivity should patch-test and avoid leave-on use above the IFRA-derived dermal limit, since even the archive's own max_dermal_pct (1.85%) is calculated from the IFRA farnesol Category 5A leave-on cap rather than a whole-oil safety monograph.

About this composition
This record combines the public 1991 Journal of Essential Oil Research abstract for exact major-component percentages with a directly readable March 9, 2026 supplier COA and live July 7, 2026 supplier/product-page checks for the exact INCI, flower part, steam-distilled production, odor profile, and physical constants of current commercial pomelo flower oil listings. The 1991 Vietnam flower-oil paper reports a nerolidol / limonene / linalool / farnesol-led profile, while the June 23, 2026 cultivar-comparison abstract confirms that pomelo flower essential oils remain terpenoid-dominant and that farnesol is a major marker in at least one current cultivar set. On July 7, 2026 I re-checked the live Scent.vn product page HTML and directly extracted text from the public COA PDF at `https://scent.vn/cdn/shop/files/COA-POMELO-FLOWER.pdf?v=7596612286696407549`: it remains publicly readable and states `Product name: Pomelo Flower Essential Oil`, `INCI name: Citrus Maxima Flower Oil`, `Product ID: POMELO-FLOWER`, `Lot: HBUOI0326`, `Testing Date: March 09, 2026`, `Odor: Bright citrus facets blended with a rich, indolic sweet-creamy undertone`, `Specific Gravity @20˚C 0.835 -> 0.855 / 0.853`, and `Refractive Index @20˚C 1.465 -> 1.486 / 1.48`. On the same date, the live Hermitage Oils Italy mirror page for this material also remained publicly readable and independently described a Citrus maxima flower oil from China with a neroli-like but more honeyed floral profile, naming lot `PFE02` in the marketing text and exposing schema `dateModified` 2025-09-24T07:52:28+00:00. The same live Scent.vn product HTML also states that purchasers receive an IFRA compliance certificate, GCMS report, and SDS, but the public IFRA, GCMS, and SDS buttons for this exact product still point to customer-authentication links whose `return_to` target is the product page rather than an exposed file URL. I also reviewed IFRA's public standards FAQ on July 7, 2026, which states that official IFRA Certificates of Conformity are generally not issued for raw materials such as citrus essential oils, so supplier-issued conformity communication or a readable raw-material technical dossier remains the needed safety source. Because no public oil-specific raw-material certificate with numeric category limits was reachable, the stored oil-level dermal ceiling is derived conservatively from the verified IFRA Category 5A farnesol limit of 0.29% and the cited flower-oil farnesol content of 15.7%, giving an inferred finished-product ceiling of about 1.85% for this profile. Relative to pomelo peel oils, the flower oil remains more floral, more indolic, and more sesquiterpenic.

- traditionally associated with promoting a fresh, comforting atmosphere
- shares the general reputation of citrus-blossom oils (similar to neroli-type profiles) for gentle floral character

What we're still learning · 4 data gaps
Good decisions start with knowing what is — and isn't — in the evidence.
- No public oil-specific raw-material dermal certificate with numeric category limits was reachable for this exact flower oil. The stored `max_dermal_pct` 1.85 is therefore a constituent-based derivation from the verified IFRA Farnesol Category 5A limit of 0.29% and the cited flower-oil farnesol content of 15.7%, not a supplier-published pomelo-flower certificate value. The missing stronger source type remains a readable supplier raw-material conformity statement, SDS section, GCMS dossier with safety section, or primary safety monograph for Citrus maxima flower oil. Live review on 2026-07-07 confirmed that the Scent.vn product HTML for `https://scent.vn/en/products/pomelo-flower-essential-oil` exposes a certificate carousel with cards for COO, COA, IFRA Certificate of Conformity, GCMS Chromatography Report, and Safety Data Sheet; the COA card routes through `/customer_authentication/login?return_to=%2Fcdn%2Fshop%2Ffiles%2FCOA-POMELO-FLOWER.pdf%3Fv%3D7596612286696407549`, and the direct COA file URL still returns HTTP 200 as `application/pdf` with content-length 535640 and canonical file link `https://cdn.shopify.com/s/files/1/0744/9886/7479/files/COA-POMELO-FLOWER.pdf`. By contrast, the IFRA, GCMS, and SDS cards for this exact product all route to `/customer_authentication/login?return_to=%2Fen%2Fproducts%2Fpomelo-flower-essential-oil&locale=en&ui_hint=full` instead of a public file path or readable numeric category table. The live IFRA guidance page `https://ifrafragrance.org/using-the-standards`, reviewed on 2026-07-07, also states that IFRA Certificates are generally not issued for raw materials and that suppliers instead communicate raw-material conformity to clients, which makes a readable supplier technical dossier or raw-material conformity statement the practical missing public source here. No alternate public supplier for this exact flower oil surfaced with a readable numeric limit on 2026-07-07.
- The exact constituent percentages are supported by the public Journal of Essential Oil Research abstract, but a directly readable full-text composition table for the 1991 Vietnam flower-oil paper is still missing.
- Odor intensity 68 normalizes source language such as bright citrus, rich indolic, sweet-creamy, floral, and fresh into the archive's 0-100 scale rather than transcribing a published numeric intensity.
- No public source located in this pass gave directly measured volatility-rate or tenacity-hour values.
