The Full Story

Diphenyl oxide (CAS 101-84-8, diphenyl ether) is a simple aromatic ether with warm, floral-waxy, geranium-like scent and slight metallic quality.

Sits at the intersection of floral and chemical: enough organic character to read as flower, enough metallic edge to suggest something manufactured.

Functions as a heart modifier in geranium, rose, and warm-floral compositions.
