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.

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.

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.Fruit with its peel
With citrus and leafy contrastsExplore a fruit sketch that includes a suggestion of peel or leaf. Compare those accents separately against the fruity reference, noticing whether they create a fresher impression or pull the idea away from the fruit you imagined.
An orchard in bloom
With rose or another familiar flowerPlace the fruity direction beside a simple floral accord. Keep a flower-only comparison and assess whether the fruit reads as a supporting accent, a juicy centre or a separate note that needs a different setting.
Fruit and cream
With vanilla and soft wood directionsSketch a more rounded fruit idea with vanilla as one variation and soft wood as another. Compare sweetness and texture before combining both, leaving room for the original fruity character to remain identifiable in the study.
