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.

CAS numbers (comment): The scope of this Standard includes, but is not limited to the CAS number(s) indicated above; any other CAS number(s) used to identify this fragrance ingredient should be considered in scope as well.
Contributions from other sources: None to consider
Flavor use consideration: Due to the possible ingestion of small amounts of fragrance ingredients from their use in products in Categories 1 and 6, materials must not only comply with IFRA Standards but must also be recognized as safe as a flavoring ingredient as defined by the IOFI Code of Practice (www.iofi.org). For more details see chapter 1 of the Guidance for the use of IFRA Standards.
IFRA Standard type: RESTRICTION
Intrinsic property driving the risk management measure: PHOTOTOXICITY
Restricted ingredients due to phototoxicity considerations: notes: This Standard is set due to the phototoxic effects of Methyl β-naphthyl ketone. For more detailed information on the application of this Standard, please refer to the note on phototoxic ingredients in chapter 1 of the Guidance for the use of IFRA Standards.

Creative ideas to explore
Creative directions, not tested formulas.Powdered petals
With rose and soft floral notesExplore a powdery floral sketch around a familiar flower reference. Compare the changing texture with the flower alone and decide whether the powder impression should feel like a gentle finish or the central subject of the composition.
A smooth wood frame
With sandalwood and a restrained muskSet the powdery character against a simple soft wood backdrop. Compare a musk variation separately, noting whether it brings your imagined texture into focus or makes the composition less distinct than the original reference.
Light through powder
With bergamot and a bright peel ideaTry a brighter contrast with citrus while keeping the powdery material constant. Compare the opening and later impressions, choosing whether the brief benefits from that change of light or calls for a more continuous soft character.
