About this material
Benzyl Alcohol is a natural component of a number of essential oils; including Jasmine, Styrax and Ylang Ylang. It has antiseptic and antibacterial properties that allows this material to be effectively used as a preservative, even in its synthetic form, prolonging the freshness of a formula by stopping bacteria from forming a wall around itself; meaning a second generation of microbes will be unable to form.
Use as a natural fixative and blending agent in floral compositions.
Arctander says of this material: “Used in perfumery as a blender, in some florals quite extensively. Jasmine, Gardenia and Lilac may often be composed using Benzyl Alcohol”

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.
