About this material
Aurantiol
Hydroxycitronellal-Methyl Anthranilate (Schiff Base)
Aurantiol by Givaudan, is probably the best known Schiff base.
Aurantiol Schiff Base is extensively used in a large variety of floral notes such as Orange Blossom, Linden Blossom and Tuberose.
Used in citrus cologne types, it acts as an excellent fixative as well as exalting the top notes.
It gives an oriental character when used in amber and chypre compositions and blends particularly well with macrocyclic musks.
Due to its high viscosity, it can be challenging to handle this material in its raw form, which is why we offer it in a more manageable dilution.

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.
