Diphenyl Oxide (crystalline solid)

Diphenyl Oxide (Crystalline Solid) is a well-known fragrance ingredient valued in perfumery for its fresh, slightly floral, and delicately green character. Its scent profile is often described as clean, airy, and subtly reminiscent of geranium and rose, with a faint lemony and metallic freshness that gives it a distinctive brightness.

The material typically appears as white crystalline flakes or solid crystals, which may melt into a clear liquid upon gentle warming. It is appreciated for its excellent stability and diffusive freshness in fragrance compositions, where it contributes a clear and radiant aromatic effect.

In practical perfumery, Diphenyl Oxide is frequently used to support rose and geranium accords, while also adding freshness and lift to floral compositions. It blends particularly well with rose, geranium, citronellol, phenyl ethyl alcohol, and green notes, making it a useful ingredient in fresh floral perfumes, classic rose structures, and bright modern fragrance compositions.
