Diphenyl oxide

Description and usage notes:

A strong diffusive green note in the direction of geranium leaf. Recommended to evaluate at 1% or less. It is more green and less floral than rose oxide. Apart from the obvious rose/geranium usage, it is perfect to give green lift and diffusion to citrus / clean / aldehydic fragrances. It also works well in a mango or pineapple accord but like rose oxide, it needs to be used alongside other ingredients and bases to control the harsh-metallic character.

Although a solid, this material melts very easily (at 28 Celsius). Arctander suggests these uses: “… It is not confined exclusively to Geranium and Rose types, since Fougeres, New Mown Hay and Hyacinth, to mention a few, can benefit from this chemical. Like many other low-cost perfume chemicals, it is often an interesting tool in the hands of a skilled perfumer with audacity and imagination and an urge to use materials in an ‘unconventional’ way.”
