About this material
Veraspice is a recently released ‘captive’ from IFF, developed through a holistic R&D approach.
It combines warm balsamic spice, sweet tobacco leaf character and dry woody facets to create an enhacing profile similar to Iso Eugenol and Eugenol.
This next generation ingredient showcases the modern fragrance research conducted at IFF, blending detailed experimental observation, molecular modelling, and performance assessment.
A unique warm spice reminiscent of cloves embodying natural white floral notes along with smooth tobacco leaves.
Blends well with Kohinool, Trimofix, Prismantol, Vetiver LMR & Ethyl Vanillin.
Useful in the creation of spicy florals such as Lily, Carnation, Tuberose and Ylang, adding naturalness to Rose and muguet creations.
It does not discolor like other spicy notes, bringing radiance to fresh Linalool types and blooming to floral notes like Roses and Ylang fragrances.
For Saffron and Leather compositions, Verapsice TSCA SNUR really works in a middle eastern context and adds another fascinating elegant and smoky facette to oud style fragrances.

Creative ideas to explore
Creative directions, not tested formulas.Spice among petals
With rose and a clear floral accordExplore a floral study with the spicy material as the changing accent. Compare it against the flower alone, deciding whether the contrast suggests warmth, brightness or a more pronounced spice character that deserves a different brief.
Peel and spice
With bergamot and an aromatic directionSketch a brighter spice idea around citrus peel, then compare an herbal variation separately. Evaluate which setting makes the material’s listed character easiest to recognise and whether the opening still matches the composition you want to build.
A textured wood
With sandalwood and an amber directionPlace the spice character against a simple wood backdrop and compare a warmer amber variation. Keep the wood-only reference close so you can judge the contribution of each change without mistaking a richer blend for a better one.
