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.Leaf and blossom
With rose and garden floralsExplore a green floral sketch around a clear flower reference. Compare the leafy accent with the flower alone and decide whether the scene suggests a cut stem, a growing garden or a greener abstraction you want to develop.
Peel and leaf
With bergamot and herbal directionsUse citrus as a bright setting for the green material, then try an herbal alternative as a separate variation. Keeping those contrasts apart makes it easier to choose between a peel-focused idea and a leafy cologne.
A shaded wood
With transparent woods and soft muskSketch a green wood direction with a restrained backdrop. Follow the leafy character as the study develops, comparing a wood-only reference to decide whether the scene suggests fresh branches, shaded timber or a softer woodland impression.
