About this material
Bergamal by IFF is a premium synthetic citrus aldehyde renowned in perfumery for its clear, uplifting bergamot character.
Bergamal delivers a fresh, lemon-lifted bergamot aroma with smooth verbena and dry orange undertones that enhance and brighten citrus bouquets in complex compositions.
Its medium aromatic strength and good substantivity make it ideal for crafting vibrant top notes in fine fragrances and enhancing citrus and green accords.
With careful formulation and respect for IFRA usage limits, Bergamal adds clarity, freshness and a beautifully nuanced citrus aldehydic edge to premium perfumery blends.

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.

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.

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.
