About this material
Dimethyl Phenyl Ethyl Carbinyl Acetate BHT by IFF
Elderflower, Honeysuckle, and other floral fragrances benefit greatly from this highly valuable traditional material.
It also proves exceptional in a diverse range of non-floral fragrances.
Despite its strong staying power, it maintains a balanced presence even in its pure form.
Lasting approximately a day on a smelling strip, it functions as a middle to base note ingredient and offers fixative properties as well.
According to IFF, it possesses a persistent, sweet floral aroma with leafy characteristics and a rich balsamic undertone.
It finds utility in perfumery for various applications, such as enhancing Clary Sage variations in Fougeres, Chypres, Lavender compositions and serving as a green-floral undertone and variant in Gardenia or Tuberose.
ts compatibility with Dimethyl Benzyl Carbinol allows for the creation of Elderflower notes (Sureau), while also contributing well-rounded undertones in Honeysuckle and similar fragrances.

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.
