Supplier reference and data limits
Fraterworks explicitly pairs Celeriax with CAS 17369-59-4, propylidene phthalide and INCI 3-PROPYLIDENEPHTHALIDE. Its reseller disclaimer names IFF, but its linked SDS visually identifies PRODANAX supplied by Ventos-VOS Pte. Ltd. Manufacturer and exact commercial-grade equivalence are unresolved, so house and registered-mark fields are omitted. Not Celery Ketone or celery seed oil. Apionax is mentioned as a supplier-page synonym, but neither Apionax nor Prodanax is made an automatic cross-grade alias here.
Linked SDS version 4.0/GHS/EN revised 07-02-2025, printed 29-07-2026, names a substance and declares 3-propylidene phthalide CAS 17369-59-4 at >=50% in its hazardous-constituent table. This is a disclosure band, not exact purity or evidence of 50% dilution. Assay, E/Z ratio, carrier and lot composition remain unknown; no point constituents inferred. No natural-manufacture claim verified; is_natural=false follows the aroma-chemical filing and does not attest a production route.
Safety review required. Product page states IFRA 51 no restriction for Category 4 and elsewhere 100%, but supplies no corresponding certificate link. No certificate-backed cap, unlimited supplier_ifra record or official CAS-based restriction flag is encoded. No product-specific allergen declaration verified; absence is not established.
The linked PRODANAX SDS lists H302 and H317, Warning. These are linked-document hazards with unresolved exact-grade applicability, not an independently verified IFF Celeriax hazard assessment.
Supplier describes a pale yellow liquid. The 284-hour strip value is a sourced catalog datum with undisclosed test conditions, not skin longevity. Evaluation dilution and numerical strength are unknown.
