About this material
Freesia Heptanol
Dimetol has a very natural fresh character that is extremely useful in floral, citrus, woody, lavender and tobacco creations.
With its unique and sparkling character, it’s no wonder Dimetol has proved to be such a great success in fragrance designed for men.
Powerful fresh Lime-like material with a citrusy floral and sweet odour and little to no terpenic undertones.

Creative ideas to explore
Creative directions, not tested formulas.A leafy cologne
With geranium and herbal notesSketch a citrus opening with a green or herbal counterpoint. Compare the leafy version with the citrus alone, noting whether the added direction suggests peel, garden freshness or an herbal character that changes the brief.
Citrus and grain
With a transparent wood directionExplore a spare citrus-and-wood structure, keeping the wood choice simple. Follow both the opening and later impression to see whether the composition keeps a clear outline as the bright citrus character changes through the evaluation.
Petal brightness
With rose and airy floral notesUse a familiar floral accord as the setting for a brighter citrus variation. Compare the flower with and without the citrus material, then decide whether to emphasise a fresh opening or a more continuous floral impression.
