About this material
Florol by Firmenich is a masterfully crafted modern floral ingredient that embodies elegance, radiance, and refined sensuality.
Designed to evoke the luminous freshness of blooming petals, Florol brings a sophisticated, contemporary floral character that feels both airy and substantial.
Opening with a clean, dewy brightness, it immediately suggests freshly cut flowers kissed by morning light.
As it unfolds, Florol reveals a delicate yet expressive heart—softly rosy, subtly fruity, and gracefully diffusive—enhancing compositions with a natural floral lift that never feels heavy or overpowering.
Its smooth, velvety texture adds a polished softness, seamlessly blending into both classic bouquets and modern minimalist accords.
Highly versatile, Florol is prized by perfumers for its ability to amplify transparency while maintaining depth.
It pairs beautifully with citrus notes for a sparkling freshness, enriches white florals with added dimension, and lends a refined elegance to musks and woody bases.
In essence, Florol is the signature of understated luxury—an ingredient that whispers rather than shouts, leaving a lasting impression of purity, sophistication, and contemporary floral beauty.
Perfect for fine fragrance creations seeking a clean, radiant, and effortlessly chic identity.
Florol is fresh, soft and natural and can be used in almost all perfume types where it gives elegant diffusion without changing the character of the fragrance.
It is a very stable and substantive building block that can also be used to replace less stable floral aldehydes.

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.

Creative ideas to explore
Creative directions, not tested formulas.Petals and peel
With bergamot and a light citrus ideaExplore a brighter version of the floral character using a simple citrus counterpoint. Compare it with the unchanged flower accord and note whether the citrus frames the bloom or becomes the main subject of the sketch.
Stem and blossom
With geranium and leafy notesSketch the flower with a greener setting, keeping leaf and blossom as distinct ideas. Compare a clean floral reference with the greener version to decide how much of the imagined stem and garden belongs in the composition.
Petals over wood
With a transparent wood directionPlace the floral material against a spare wood backdrop and follow the balance through the evaluation. Try a softer wood variation separately, then choose whether your flower needs an open, airy setting or a smoother, more enveloping frame.
