Fragrance allergen reference
Generic regulatory reference only. This is not a supplier allergen declaration, measured composition, allergen-free claim or finished-product labelling assessment.
Raw-material reference based on recorded CAS numbers. A CAS match identifies a reference entry; it does not verify the supplied grade, composition, purity or finished-product compliance. Naturals, bases and mixtures require composition review.
European Union / Northern Ireland
No direct listed-entry CAS match in this jurisdiction’s held reference set. This does not mean the material is allergen-free. Constituents, grouped entries and natural-material composition may require further review.
Finished-cosmetic declaration thresholds: greater than 0.001% leave-on; greater than 0.01% rinse-off. Apply the current target-market rules to the actual complete formulation; no concentration is inferred here.

Documentation Supply PolicyIFRA formulation guide
Generic reference only — not an IFRA certificate, compliance decision or use recommendation. The Responsible Person and qualified safety assessor must assess the actual finished formula using current applicable IFRA Standards, supplementary documentation where available and the CPSR.
Raw-material reference based on recorded CAS numbers. A CAS match identifies a reference entry; it does not verify the supplied grade, composition, purity or finished-product compliance. Naturals, bases and mixtures require composition review.
Source: 51st Amendment overview, held source checked 2026-10-21. Bundle 2026-10-27. Individual Standards prevail over the overview.
No direct IFRA overview entry matched the recorded CAS in this held dataset. This does not mean unrestricted use, absence of relevant Standards or compliance. Constituent restrictions may still apply.

Creative ideas to explore
Creative directions, not tested formulas.Polished petals
With rose and soft floral notesExplore an aldehydic floral silhouette around a simple rose accord. Compare the opening and later impression with an unchanged floral reference; decide whether the effect feels airy, waxy or abstract before adding further complexity.
Citrus in white
With bergamot and a musk directionBuild a study around citrus brightness and a restrained musk backdrop. Let the aldehydic material be the changing variable, then note whether it supports the peel impression or takes the sketch towards a more abstract clean accord.
A softer frame
With sandalwood and powdery notesSet the listed aldehydic character against a soft wood or powder direction. Compare the balance through the evaluation rather than judging only the first impression, and keep any successful version simple enough to understand what changed.
